Description

TECHNICAL FIELD

[0001] The present application relates to the field of agricultural planting technology, in particular to a greenhouse leaf roller prevention system and a control method and control device thereof. BACKGROUND

[0002] Greenhouse tomato is an important economic crop and is widely planted all over the world. Its high-yield and efficient cultivation mode requires not only high-quality breeding technology, but also effective disease and pest control measures. However, the greenhouse environment provides suitable temperature and humidity conditions for tomato growth, and also provides conditions for the occurrence of various diseases and pests. Among them, the leaf roller is one of the most serious pests in greenhouse tomato cultivation.

[0003] The leaf roller is a typical leaf pest. Its larvae cause leaf damage, wilting and even death of the plant by feeding on tomato leaves. The damage of the leaf roller not only affects the normal photosynthesis of the tomato and reduces the yield, but also seriously affects the quality of the tomato fruit, leading to a decrease in the market competitiveness of agricultural products. The leaf roller has strong adaptability and reproductive capacity, and its reproductive cycle is short. The eggs, larvae and adults can all hatch and grow in the greenhouse, causing the population to grow rapidly. If not controlled in time, it can easily lead to large-scale outbreaks, causing great economic losses to greenhouse tomato cultivation.

[0004] Currently, the prevention and control of the leaf roller mainly relies on the use of chemical pesticides. However, it may lead to excessive pesticide residues in agricultural products, affecting food safety, and may even cause drug resistance problems. In order to reduce the use of chemical pesticides and avoid their negative effects, in recent years, researchers at home and abroad have begun to explore non-chemical means such as biological control and physical control, and have achieved certain control effects. However, single control measures are often difficult to control the occurrence of the leaf roller stably in the long term.

[0005] In addition, although some greenhouse tomato growers have taken physical control measures such as the use of yellow sticky traps and sex pheromone traps, the control effect is greatly affected by environmental factors, so it is still necessary to combine other measures to enhance the control effect. In particular, timely monitoring and early warning are crucial for control effect at the initial stage of the occurrence of the leaf roller.

[0006] In summary, the existing control technology still has problems such as unstable control effect, excessive reliance on chemical pesticides, and food safety.

[0007] Therefore, there is an urgent need for a comprehensive control method that integrates early warning, physical control and reasonable use of chemical pesticides to achieve efficient control of the leaf roller of greenhouse tomato, while reducing the amount of pesticide use and ensuring the safety and yield of agricultural products. SUMMARY

The method of the application combines physical, biological and chemical methods, can not only effectively prevent and control leaf-rollers from breaking out in large scale, reduce prevention and control cost, improve tomato yield and quality, but also avoid the agricultural product safety hidden trouble problem caused by excessive use of pesticides by reasonably controlling the use of chemical pesticides, only when the number of leaf-rollers is higher than a certain number, the chemical pesticides are used.

[0014] It is emphasized here that the solar insecticidal lamp belongs to physical prevention and control, the bacillus thuringiensis insecticide belongs to biological prevention and control, and the spinosyn insecticide belongs to chemical prevention and control, when the number of leaf-rollers is small, physical prevention and control can achieve good insect killing effect, when the number of leaf-rollers increases, the bacillus thuringiensis insecticide is used for biological prevention and control, which is mainly aimed at killing leaf-roller larvae, and the bacillus thuringiensis insecticide is harmless to human beings, so that the food safety of products can be ensured, when the number of leaf-rollers further increases, it indicates that there are a large number of leaf-roller adults in the greenhouse, at this time, the spinosyn insecticide is used for chemical prevention and control, which can kill leaf-roller larvae and adults at the same time, so that the method of the application can not only effectively prevent and control leaf-rollers from breaking out in large scale, but also avoid the agricultural product safety hidden trouble problem caused by excessive use of pesticides.

[0015] The bacillus thuringiensis insecticide can be selected as a 200-fold diluted insecticide, that is, 1 volume of bacillus thuringiensis is mixed with 200 volumes of diluent to form the bacillus thuringiensis insecticide.

[0016] In some embodiments, the greenhouse leaf-roller control system further comprises an acid-base adjusting device and a pH sensor, the acid-base adjusting device is configured to spray an acidic solution or a basic solution, and the pH sensor is configured to detect the pH value of the culture soil. The control method further comprises: when the pH value of the culture soil is less than a fourth preset value, controlling the acid-base adjusting device to spray a basic solution into the greenhouse; and when the pH value of the culture soil is greater than a fifth preset value, controlling the acid-base adjusting device to spray an acidic solution into the greenhouse.

[0017] In the technical solution, the greenhouse further comprises an acid-base adjusting device and a pH sensor. The acid-base adjusting device is configured to spray an acidic solution or a basic solution. The pH sensor is in contact with the culture soil and is configured to detect the pH value of the culture soil. When the pH value of the culture soil is less than a fourth preset value, the acid-base adjusting device is controlled to spray a basic solution into the greenhouse. When the pH value of the culture soil is greater than a fifth preset value, the acid-base adjusting device is controlled to spray an acidic solution into the greenhouse.

[0018] In some embodiments, the acidic solution can be at least one of sodium phosphate dibasic and ammonium sulfate, and the basic solution can be at least one of potassium hydroxide and potassium bicarbonate.

[0019] Specifically, using sodium phosphate dibasic or ammonium sulfate to adjust the pH of the soil to be slightly acidic can promote the absorption of phosphorus, iron and other elements by tomatoes, enhance root development and fruit quality. Potassium hydroxide or potassium bicarbonate is suitable for neutralizing over-acidic soil and providing potassium to improve disease resistance and sugar accumulation. Reasonable adjustment of acidic and basic solutions can optimize soil pH and improve nutrient availability, but excessive acidification or alkalization should be avoided to maintain healthy growth and high yield of tomatoes.

[0020] In some embodiments, the fourth preset value can be 5.5 to 6.0, for example, the fourth preset value is equal to 6.0. The fifth preset value can be 7.0 to 7.5, for example, the fifth preset value is equal to 7.0. By adding a soil pH adjusting system, the present application automatically adjusts the soil pH by adjusting the soil pH with an acid-base solution, maintains the pH at 6.0-7.0, destroys the suitable living environment of leaf-roller larvae, and maintains the optimal growth environment of plants.

[0021] In some embodiments, the greenhouse leaf-roller control system further comprises a temperature and humidity sensor and at least one ventilation opening. The temperature and humidity sensor is configured to detect the environmental temperature and humidity in the greenhouse. The ventilation opening can be opened or closed to realize air exchange or blockage between the inside and outside of the greenhouse. The control method further comprises: when the temperature in the greenhouse is greater than a first preset temperature or the humidity in the greenhouse is greater than a first preset humidity, opening the ventilation opening to realize air exchange between the inside and outside of the greenhouse; and when the temperature in the greenhouse is less than or equal to the first preset temperature and the humidity in the greenhouse is less than or equal to the first preset humidity, closing the ventilation opening.

[0022] The first preset temperature can be 28-30 DEG C, for example, 30 DEG C. The first preset humidity can be 55-75%, for example, 55%.

[0023] In the technical scheme, when the temperature in the greenhouse is higher than 30 DEG C, the ventilation opening is opened to speed up air circulation; when the temperature is lower, the ventilation opening is appropriately closed to reduce energy waste. Similarly, when the humidity is too high, the ventilation opening is also opened to speed up air circulation. This measure avoids the accumulation of high humidity environment by improving air circulation, thereby inhibiting the breeding of leaf-mining moths and promoting the healthy growth of tomato plants. In addition, a plurality of fans can be arranged in the greenhouse, and the fans are started when the temperature in the greenhouse is greater than the first preset temperature or the humidity in the greenhouse is greater than the first preset humidity, thereby speeding up air circulation.

[0024] In some technical schemes, the greenhouse leaf-mining moth control system also includes a water mist device and a soil humidity sensor, the water mist device can spray water mist, and the soil humidity sensor is used to detect the humidity of the culture soil, and the control method further includes: when the humidity of the culture soil is less than a second preset humidity, controlling the water mist device to spray water mist into the greenhouse.

[0025] In the technical scheme, the greenhouse also has a water mist device and a soil humidity sensor, and the water mist device sprays water mist into the greenhouse when the humidity of the culture soil is less than a second preset humidity. The present application adopts an intelligent drip irrigation system, combines soil humidity sensor data, accurately controls water supply, and avoids poor plant growth and occurrence of diseases and pests caused by excessive dryness.

[0026] The second preset humidity is greater than or equal to 60% and less than or equal to 70%, for example, 60%. That is, 60% is the minimum humidity of the soil suitable for tomato growth.

[0027] In addition, the water mist device of the present application can also adjust the irrigation frequency and water volume based on the temperature outside the greenhouse, for example, when the external environment is greater than or equal to 28 DEG C, the irrigation frequency and the single water injection amount are increased, and when the external environment is less than or equal to 20 DEG C, the irrigation frequency and the single water injection amount are reduced, thereby ensuring that the water supply is appropriate, and long-term management can be realized.

[0028] In addition, a dehumidification device can also be arranged in the greenhouse, and the dehumidification device is started when the humidity inside the greenhouse is higher than the first preset humidity, thereby reducing the humidity inside the greenhouse and avoiding an excessively humid environment, which helps to reduce the spread of leaf-mining moths and other diseases and pests.

[0029] In some embodiments, the greenhouse leafroller control system further comprises a temperature sensor configured to obtain the temperature outside the greenhouse, and the greenhouse further comprises an alarm device, and the control method further comprises: in the case that the temperature outside the greenhouse is greater than or equal to a second preset temperature or less than or equal to a third preset temperature, controlling the alarm device to send an alarm information for replacing the greenhouse covering film, wherein the second preset temperature is greater than the third preset temperature.

[0030] In this embodiment, the second preset temperature is greater than or equal to 30℃, for example, the second preset temperature is equal to 30℃, and the third preset temperature is less than or equal to 10℃, for example, the third preset temperature is equal to 10℃. The present application can flexibly send a reminder to replace the greenhouse covering film according to the seasonal change. For example, a more light-transmitting material is used in summer to enhance the light and maintain the light transmittance of the greenhouse, and a heat preservation material is used in winter to increase the indoor temperature and maintain the heat preservation of the greenhouse. This adjustment can effectively control the light intensity and temperature in the greenhouse, and create a more suitable growth environment for the tomato plants, thereby reducing the breeding probability of the leafroller. The greenhouse covering film comprises one of the following: a polyethylene film, a polypropylene film or a polycarbonate film.

[0031] In some embodiments, the step of controlling the pesticide spraying device to spray the Bacillus thuringiensis pesticide into the greenhouse every second preset time interval specifically comprises: controlling the pesticide spraying device to spray the Bacillus thuringiensis pesticide into the greenhouse in the form of water mist every second preset time interval, and the Bacillus thuringiensis pesticide covers all the leaves of the plants.

[0032] In some embodiments, the step of controlling the pesticide spraying device to spray the spinetoram pesticide into the greenhouse every third preset time interval specifically comprises: controlling the pesticide spraying device to spray the spinetoram pesticide into the greenhouse in the form of water mist every third preset time interval, and the spinetoram pesticide covers all the leaves of the plants.

[0033] In this embodiment, the pesticide is sprayed in the form of water mist, which improves the adhesion rate of the pesticide and the contact probability of the larvae, thereby improving the pesticide effect. The particle diameter of the water mist can be greater than or equal to 50μm and less than or equal to 100μm.

[0034] In some embodiments, the first preset time interval is greater than or equal to 6 days and less than or equal to 8 days, for example, 7 days.

[0039] In some embodiments, the third preset value is greater than 1000 and less than or equal to 1200; for example, the third preset value is equal to 1000.

[0040] In these embodiments, the time interval for killing pests and other parameters are limited to balance the control effect and pesticide residues, so that the residues are lower than the national standard and the pests do not develop resistance.

[0041] The second aspect of the present application provides a control device of a greenhouse leaf-roller control system, comprising a memory and a processor, the memory stores computer programs or instructions, and the processor executes the computer programs or instructions to realize the control method of the greenhouse leaf-roller control system according to any one of the first aspect of the present application.

[0053] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0054] like Figure 1 and Figure 3 As shown in the first aspect embodiment of the present invention, the control method of the greenhouse leafminer control system 1 includes a sex pheromone trapping device 102, a solar insecticidal lamp 106, and an insecticide spraying device 104.

The control method includes: S102: The controlled pheromone trapping device is activated once every first preset time interval and the number of leaf miners per thousand square meters is monitored. S104: Determine whether the number of leaf miners per thousand square meters is greater than or equal to the third preset value. If yes, execute S106; otherwise, execute S108. S106: Control the insecticide spraying device to spray ethyl spinosad insecticide into the greenhouse once every three preset time intervals; S108: Determine whether the number of leaf miners per thousand square meters is greater than the second preset value and less than the third preset value; if yes, execute S110; if no, execute S112. S110: Control the insecticide spraying device to spray Bacillus thuringiensis insecticide into the greenhouse once every second preset time interval; S112: Determine whether the number of leaf miners per thousand square meters is greater than or equal to the first preset value and less than or equal to the second preset value. If yes, execute S114; otherwise, execute S102. S114: Controls the solar-powered insecticidal lamp to turn on.

[0055] The greenhouse leafroller control system control method provided by the application is characterized in that a sex pheromone trapping device 102, a solar insecticidal lamp 106 and an insecticide spraying device 104 are arranged in the greenhouse, the sex pheromone trapping device is controlled to be turned on once regularly, and the number of leafrollers per 1000 square meters is monitored; when the number of leafrollers per 1000 square meters is greater than or equal to a first preset value and less than or equal to a second preset value, it indicates that the number of leafrollers is relatively small at this time, the solar insecticidal lamp is controlled to be turned on at this time, and insect killing is realized at night through the solar insecticidal lamp; when the number of leafrollers per 1000 square meters is greater than the second preset value and less than a third preset value, it indicates that the number of leafrollers is relatively large at this time, the insecticide spraying device is controlled to spray bacillus thuringiensis insecticide into the greenhouse regularly at this time to realize insect killing; and when the number of leafrollers per 1000 square meters is greater than or equal to the third preset value, it indicates that leafrollers are likely to break out in large scale at this time, the insecticide spraying device is controlled to spray spinetoram insecticide into the greenhouse regularly at this time to realize insect killing. The method of the application combines physical, biological and chemical methods, can not only effectively prevent and control the large-scale outbreak of leafrollers, reduce the control cost, improve the yield and quality of tomatoes, but also avoid the problem of agricultural product safety hazards caused by excessive use of pesticides by reasonably controlling the use of chemical pesticides, only when the number of leafrollers is higher than a certain number.

[0056] The first preset value is less than the second preset value, and the second preset value is less than the third preset value.

[0057] It is emphasized here that the solar insecticidal lamp belongs to physical control, the bacillus thuringiensis insecticide belongs to biological control, and the spinetoram insecticide belongs to chemical control. When the number of leafrollers is small, physical control can achieve good insect killing effect. When the number of leafrollers increases, biological control of the bacillus thuringiensis insecticide is adopted, which is mainly aimed at killing the larvae of leafrollers, and the bacillus thuringiensis insecticide is harmless to humans, so that the food safety of products can be ensured. When the number of leafrollers further increases, it indicates that there are a large number of adult leafrollers in the greenhouse, and chemical control of the spinetoram insecticide is adopted at this time, which can kill the larvae and adult leafrollers at the same time, so that the method of the application can not only effectively prevent and control the large-scale outbreak of leafrollers, but also avoid the problem of agricultural product safety hazards caused by excessive use of pesticides.

[0058] The bacillus thuringiensis insecticide can be selected as a 200-fold diluted insecticide, that is, 1 volume of bacillus thuringiensis is mixed with 200 volumes of diluent to form the bacillus thuringiensis insecticide. The spinetoram insecticide can be selected as a 1000-fold diluted insecticide, that is, 1 volume of spinetoram is mixed with 1000 volumes of diluent to form the spinetoram insecticide.

[0059] In some embodiments, the greenhouse leaf roller control system 1 optionally further comprises an acid-base adjusting device 110 for spraying an acidic solution or a basic solution, and a pH sensor 112 for detecting the pH value of the culture soil. The control method further comprises: when the pH value of the culture soil is less than a fourth preset value, controlling the acid-base adjusting device to spray a basic solution into the greenhouse; and when the pH value of the culture soil is greater than a fifth preset value, controlling the acid-base adjusting device to spray an acidic solution into the greenhouse.

[0060] In this embodiment, the greenhouse further comprises an acid-base adjusting device and a pH sensor. The acid-base adjusting device is used for spraying an acidic solution or a basic solution. The pH sensor is in contact with the culture soil and is used for detecting the pH value of the culture soil. When the pH value of the culture soil is less than a fourth preset value, the acid-base adjusting device is controlled to spray a basic solution into the greenhouse. When the pH value of the culture soil is greater than a fifth preset value, the acid-base adjusting device is controlled to spray an acidic solution into the greenhouse.

[0061] The acidic solution can be at least one of sodium phosphate dibasic and ammonium sulfate, and the basic solution can be at least one of potassium hydroxide and potassium bicarbonate.

[0062] Specifically, using sodium phosphate dibasic or ammonium sulfate to adjust the soil pH to slightly acidic can promote the absorption of phosphorus, iron and other elements by tomatoes, enhance root development and fruit quality. Potassium hydroxide or potassium bicarbonate is suitable for neutralizing over-acidic soil and providing potassium to improve disease resistance and sugar accumulation. Reasonable adjustment of acidic and basic solutions can optimize soil pH and improve nutrient availability, but excessive acidification or alkalization should be avoided to maintain healthy growth and high yield of tomatoes.

[0063] The fourth preset value can be 5.5 to 6.0, for example, the fourth preset value is equal to 6.0. The fifth preset value can be 7.0 to 7.5, for example, the fifth preset value is equal to 7.0. The present application adds a soil pH adjusting system to automatically regulate the soil pH by adjusting the soil pH with acidic and basic solutions, maintains the pH at 6.0-7.0, destroys the suitable living environment of leaf roller larvae, and maintains the optimal growth environment for plants.

[0064] In some embodiments, the greenhouse leaf roller control system 1 optionally further comprises a temperature and humidity sensor 126 for detecting the environmental temperature and humidity in the greenhouse 2, and at least one ventilation opening 114 that can be opened or closed to realize air exchange or blockage between the inside and outside of the greenhouse 2. The control method further comprises: opening the ventilation opening to realize air exchange between the inside and outside of the greenhouse when the temperature in the greenhouse is greater than a first preset temperature or the humidity in the greenhouse is greater than a first preset humidity; and closing the ventilation opening when the temperature in the greenhouse is less than or equal to the first preset temperature and the humidity in the greenhouse is less than or equal to the first preset humidity.

[0065] The first preset temperature can be 28-30°C, for example, 30°C. The first preset humidity can be 55-75%, for example, 55%.

[0066] In this embodiment, when the temperature in the greenhouse exceeds 30°C, the ventilation opening is opened to accelerate air circulation; when the temperature is lower, the ventilation opening is appropriately closed to reduce energy waste. Similarly, when the humidity is too high, the ventilation opening is also opened to accelerate air circulation. This measure avoids the accumulation of high-humidity environment by improving air circulation, thereby inhibiting the breeding of the tomato leafminer and promoting the healthy growth of the tomato plant. In addition, a plurality of fans can be arranged in the greenhouse, and the fans are started to accelerate air circulation when the temperature in the greenhouse is greater than the first preset temperature or the humidity in the greenhouse is greater than the first preset humidity.

[0067] In some embodiments, the greenhouse tomato leafminer control system 1 also includes a water mist device 116 capable of spraying water mist and a soil humidity sensor 118 for detecting the humidity of the culture soil, and the control method further includes: when the humidity of the culture soil is less than a second preset humidity, controlling the water mist device to spray water mist into the greenhouse.

[0068] In this embodiment, the greenhouse also has a water mist device and a soil humidity sensor, and the water mist device sprays water mist into the greenhouse when the humidity of the culture soil is less than a second preset humidity. The present application adopts an intelligent drip irrigation system, combines soil humidity sensor data, accurately controls water supply, and avoids poor plant growth and the occurrence of diseases and pests caused by excessive dryness.

[0069] The second preset humidity is greater than or equal to 60% and less than or equal to 70%, for example, 60%. That is, 60% is the minimum humidity of the soil suitable for tomato growth.

[0070] In addition, the water mist device of the present application can also adjust the irrigation frequency and water volume based on the temperature outside the greenhouse, for example, when the external environment is greater than or equal to 28°C, the irrigation frequency and the single water injection volume are increased, and when the external environment is less than or equal to 20°C, the irrigation frequency and the single water injection volume are reduced, thereby ensuring that the water supply is appropriate and long-term management can be realized.

[0071] In addition, a dehumidification device can also be arranged in the greenhouse, and the dehumidification device is started when the humidity inside the greenhouse is higher than the first preset humidity, thereby reducing the humidity inside the greenhouse and avoiding an excessively humid environment, which helps to reduce the spread of diseases and pests such as the tomato leafminer.

[0072] In some embodiments, the greenhouse leaf roller control system 1 optionally further comprises a temperature sensor 120 configured to obtain a temperature outside the greenhouse 2, and the greenhouse 2 is further provided with an alarm device 122, and the control method further comprises: in the case that the temperature outside the greenhouse is greater than or equal to a second preset temperature or less than or equal to a third preset temperature, controlling the alarm device to issue alarm information for replacing the greenhouse covering film of the greenhouse, wherein the second preset temperature is greater than the third preset temperature.

[0073] In this embodiment, the second preset temperature is greater than or equal to 30℃, for example, the second preset temperature is equal to 30℃, and the third preset temperature is less than or equal to 10℃, for example, the third preset temperature is equal to 10℃.

[0086] The method of the present application combines physical, biological and chemical methods, which not only can effectively prevent and control the large-scale outbreak of leaf rollers, reduce the control cost, improve the yield and quality of tomatoes, but also can avoid the problem of agricultural product safety caused by excessive use of pesticides by reasonably controlling the use of chemical pesticides, only when the number of leaf rollers is higher than a certain number.

[0087] In the above embodiments, optionally, the number of sex pheromone trapping devices 102 in each hectare of area is greater than or equal to 2 and less than or equal to 4. Specifically, two sex pheromone trapping devices 102 are installed per hectare before the tomato is transplanted. When the number of leaf roller bodies is monitored to increase, the number of sex pheromone trapping devices 102 is increased to four per hectare.

[0088] In the above embodiments, the number of the sticky boards 108 per hectare is optionally greater than or equal to 150.

[0089] In the above embodiments, the height of the pheromone trapping device 102 relative to the cultivation soil is 1.5 meters.

[0090] In the above embodiments, the height of the pheromone trapping device 102 relative to the cultivation soil is 1.5 meters.

[0091] In these embodiments, the parameters such as the pheromone trapping device 102, the sticky boards 108, and the hanging height are quantified to construct a physical control network, improve the interception efficiency of adult insects, and avoid interference between devices.

[0092] Another embodiment of the present application provides a control method for preventing and treating tomato leafminer in a greenhouse. The control method comprises the following steps: Before the tomato is transplanted, a pheromone trapping device is installed in the greenhouse to monitor the number of tomato leafminer per thousand square meters. Two pheromone trapping devices are installed per hectare to monitor the occurrence of tomato leafminer.

[0093] When the number of tomato leafminer per thousand square meters in the monitoring area is 1-300 or the tomato leafminer is first found on the plants in the greenhouse, yellow sticky boards are hung in the field, and no less than 150 boards are hung per hectare.

[0094] When the number of tomato leafminer increases and the number of tomato leafminer in the monitoring area is 300-1000, Bacillus thuringiensis insecticide is used, diluted 200 times, and sprayed every 7 days; when the tomato leafminer adults are in groups and eggs are found at the same time or the number of tomato leafminer in the monitoring area is greater than 1000, spinosad is used, diluted 1000 times, and sprayed every 5 days.

[0095] After the occurrence of tomato leafminer in the greenhouse, i.e., when the number of tomato leafminer is greater than or equal to a first preset value, the following adjustments are made, but are not limited to: adjusting the ventilation condition, adjusting the soil condition, adjusting the water management, pruning and training the plants, adjusting the greenhouse covering material, and adjusting the nutrient solution formula.

[0096] The adjustment of the ventilation condition includes increasing or decreasing the number of ventilation openings in the greenhouse, or adjusting the opening time and frequency of the ventilation openings.

[0097] The adjustment of the soil condition includes changing the pH value of the soil or adjusting the organic matter content in the soil.

[0098] The organic matter is mainly composed of carbon, hydrogen, oxygen, nitrogen and other elements, and contains a small amount of phosphorus, sulfur, calcium, magnesium and other elements. When the soil moisture content is 60%-80% of the water holding capacity, it is conducive to the transformation of organic matter. In the temperature range of 0-35℃, appropriate increase of temperature can promote the decomposition of organic matter.

[0099] The adjustment of water management includes controlling water supply by using drip irrigation or sprinkler irrigation system, or adjusting irrigation frequency and water volume of each irrigation.

[0100] The pruning and training of plants can promote the growth of new branches and ventilation.

[0101] The adjustment of greenhouse covering materials can control the light transmittance.

[0102] The adjustment of nutrient solution formula, the change of the proportion of nitrogen, phosphorus and potassium in the nutrient solution or the content of other trace elements can enhance the stress resistance and nutrient absorption capacity of the plants.

[0103] The proportion of nitrogen, phosphorus and potassium is controlled between 1:0.2:0.8 and 1:0.5:1.5, that is, if the nitrogen is one part, the phosphorus is 0.2-0.5 parts, and the potassium is 0.8-1.5 parts.

[0104] The content of trace elements is 2-3mg / L of iron, 0.5-1mg / L of manganese, 0.2-0.5mg / L of zinc, 0.5-1mg / L of boron and 0.05-0.1mg / L of molybdenum.

[0105] In the above embodiment, the installation height of the sex pheromone trapping device is 1.5 meters from the ground.

[0106] In the above embodiment, the hanging height of the yellow armyworm board is 1 meter from the ground.

[0107] In the above embodiment, the spraying method of the Bacillus thuringiensis insecticide is spraying, and all the leaves of the plant are covered.

[0108] In the above embodiment, the spraying method of the spinetoram insecticide is spraying, and all the leaves of the plant are covered.

[0109] In the above embodiment, the adjustment of ventilation conditions can also be: according to the indoor and outdoor temperature difference and humidity, the opening degree of the ventilation opening is automatically adjusted, when the indoor temperature of the greenhouse is greater than 30℃, the ventilation opening is opened, the fan is automatically opened, air circulation is realized, and the rest of the time remains closed.

[0110] In the above embodiment, the adjustment of soil conditions can also be: the pH value of the substrate culture soil is detected periodically, and the pH value is kept within 6.0-7.0.

[0111] In the above embodiment, optionally, the adjusting the moisture management can also be automatically adjusting the irrigation system according to the data of the soil moisture sensor.

[0112] In the above embodiment, optionally, the pruning and training step specifically comprises: pruning and training regularly according to the plant growth, removing the old leaves at the bottom every 1-2 weeks, and keeping 11-13 compound leaf blades per plant.

[0113] In the above embodiment, optionally, the adjusting the greenhouse covering material specifically comprises: replacing the appropriate greenhouse covering material according to the seasonal change, and the greenhouse covering material can be selected from one of polyethylene, polypropylene or polycarbonate.

[0114] In the above embodiment, optionally, the monitoring period of the number of leaf-roller adults is once a week.

[0115] In the above embodiment, optionally, when the number of leaf-roller adults is monitored to increase, the number of sex pheromone traps is increased to 4 per hectare.

[0116] In the above embodiment, optionally, the control method further comprises using a solar insecticidal lamp for night trapping.

[0117] In the above embodiment, optionally, the control method of the present application further comprises stopping the use of chemical pesticides when the number of leaf-roller adults is reduced to 300 or less, that is, stopping the use of spinetoram insecticide.

[0118] The control method provided by the present application can reduce the harm of leaf-roller to tomato crops, ensure the yield and quality of tomatoes, and effectively solve the problems of unstable control effect and excessive dependence on chemical pesticides in the process of controlling leaf-roller of greenhouse tomatoes.

[0119] The control method provided by the present application can reduce the harm of leaf-roller to tomato crops, ensure the yield and quality of tomatoes, and effectively solve the problems of unstable control effect and excessive dependence on chemical pesticides in the process of controlling leaf-roller of greenhouse tomatoes.

[0120] More specifically, when the number of leaf-rollers is small or initially appears, physical control measures are adopted, mainly by hanging yellow sticky insect boards in the greenhouse to capture leaf-rollers. At least 150 yellow sticky insect boards are hung per hectare, and the number of leaf-rollers is reduced by physical methods to avoid large-scale reproduction.

[0121] When the number of leaf miners increases to a certain number (300 heads per kilometer-1000 heads per kilometer), biological control methods are used, that is, Bacillus thuringiensis is sprayed. After diluting Bacillus thuringiensis 200 times, spraying every 7 days can effectively inhibit the growth of leaf miner larvae and reduce their harm to crops.

[0122] When leaf miner adults form groups and eggs are found, or when the number of leaf miners in the monitoring area exceeds 1000 heads per kilometer, chemical pesticides are used. Ethyl spinosyn (diluted 1000 times) is sprayed every 5 days to kill all stages of leaf miners and prevent further spread.

[0123] The present application also carries out a series of optimized growth management measures, including ventilation condition management, soil management, water management, plant pruning and training, greenhouse covering material management and nutrient solution formula management.

[0124] Ventilation condition management automatically adjusts the opening degree of the ventilation opening according to the temperature and humidity difference between the inside and outside of the greenhouse, ensuring air circulation in the greenhouse. When the temperature in the greenhouse exceeds 30℃, start the fan to speed up air circulation; when the temperature is lower, close the ventilation opening appropriately to reduce energy waste. This measure improves air circulation and prevents the accumulation of high humidity environment, thereby inhibiting the breeding of leaf miners and promoting the healthy growth of tomato plants.

[0125] Soil management: regularly test the soil pH value to ensure it is maintained within the appropriate range (usually 6.0 to 7.0). If the soil acidity or alkalinity deviates from the normal range, adjust it in time to maintain the best growth environment for plants. In addition, by adding organic matter to improve soil structure, the resistance and nutrient absorption capacity of the plant are further enhanced.

[0126] Water management: use an intelligent drip irrigation system combined with soil moisture sensor data to accurately control water supply. By regularly adjusting irrigation frequency and water volume, ensure appropriate water supply to avoid poor plant growth and disease and pest occurrence caused by excessive wetness or dryness. In addition, avoiding excessive wet environment helps reduce the spread of pests such as leaf miners.

[0127] Plant pruning and training: according to the growth stage of the plant and the need for disease and pest control, regularly prune and train the plant to ensure that the tomato plant maintains good ventilation conditions and light distribution. Remove old leaves and weak branches at the bottom every 1-2 weeks to promote the growth of new branches and strengthen the resistance of the plant. These measures not only optimize the morphology of the plant, but also enhance the self-defense ability of the plant against diseases and pests.

[0128] Adjustment of Greenhouse Covering Material: According to seasonal changes, the covering material of the greenhouse is flexibly replaced. For example, in summer, more light-transmitting material is used to enhance light, and in winter, heat preservation material is used to increase the temperature inside the greenhouse. This adjustment can effectively control the light intensity and temperature in the greenhouse, creating a more suitable growth environment for tomato plants, thereby reducing the breeding probability of the tomato leafworm.

[0129] Optimization of Nutrient Solution Formula: According to the growth needs of tomato plants and the occurrence dynamics of the tomato leafworm, the formula of the nutrient solution is reasonably adjusted. When the tomato leafworm first appears, the proportion of nitrogen, phosphorus, and potassium in the nutrient solution is ensured to be appropriate to meet the plant's nutritional needs and enhance the plant's growth potential; when the number of insects increases, the concentration of the nutrient solution is adjusted to maintain appropriate nutrient supply and avoid excessive growth of plants caused by excessive nutrients, further increasing the risk of plant diseases and insect pests.
