Description

Technical Field

[0001] The invention relates to the technical field of kumquat cultivation methods, in particular to a kumquat early cultivation method. Background Art

[0002] Kumquat, also known as kumquat and golden bullet, is a small evergreen fruit tree of the genus Fortunella of the Rutaceae family. Its fruit is small and round, golden in color, and has a moderate sweet and sour taste. It can be eaten fresh as a fruit, or processed into jam, juice, candied fruit and other foods, and is deeply loved by consumers. Kumquat has the characteristic of blooming and bearing fruit many times a year, which brings it a higher economic value and has broad development prospects and market demand. Through scientific cultivation and management, the yield and quality of kumquat can be further improved to meet the needs of consumers.

[0003] Kumquats bloom 4-5 times a year, and the first batch of flowers and fruits mature in late November to early to mid-December, and the fifth batch of flowers and fruits may mature in March or April of the following year. However, the fruit price of the first batch of flowers and fruits is the highest, and the fruits are large and of the best quality. In addition, the normal first batch of flowers of kumquats usually blooms around the Dragon Boat Festival, and high temperatures and heavy rains are often not conducive to preserving flowers and fruits. In recent years, due to frequent abnormal weather, the average yield of kumquats, especially new varieties such as Crisp Honey Kumquat, is generally low. Existing cultivation methods can hardly effectively cope with these challenges, resulting in the impact on the yield and quality of kumquats.

[0004] Furthermore, we disclose a method for promoting early cultivation of kumquat to advance the maturity period of kumquat and ensure the yield to improve the economic benefits of kumquat, providing technical support for the sustainable development of the kumquat industry. Summary of the Invention

[0005] In view of this, the object of the present invention is to provide a method for promoting early cultivation of kumquat, so as to advance the maturity period of kumquat and increase the yield.

[0006] Based on the above purpose, the present invention provides a method for promoting early cultivation of kumquat, comprising the following steps:

[0007] S1. Heating: During the entire cultivation period, precise temperature control is performed by heating according to the different growth stages of kumquat (pre-warming period, budding period, flowering period and young fruit period) and supplemented with red and blue light in a 3:1 ratio. During this period, new energy-saving temperature control facilities and greenhouse temperature control technology are used;

[0008] S2. Flowering promotion: Prune and fertilize before bud break, adjust nitrogen fertilizer and moderate watering after new shoots are pruned, and use chemical regulation to promote flowering if the tree is too vigorous;

[0009] S3, fruit preservation: fruit preservation treatment is carried out during the flowering period, spraying a mixture of gibberellic acid, thiobencarb and boron fertilizer for the first time, and spraying a mixture of benzylamine gibberellic acid, thiobencarb and amino acid water-soluble fertilizer 7-10 days later;

[0010] S4. Management during the fruit coloring period: artificially control the temperature difference between day and night and use a 3:1 red and blue light supplementary light to supplement the light. Use temperature control facilities to actively reduce the temperature at night. The temperature difference between day and night is controlled between 10-15 degrees.

[0011] S5. Intelligent monitoring and automated management: During the entire cultivation cycle, a variety of sensors are used to monitor the key parameters of the kumquat growth environment in real time. An early warning system is set up to automatically send an alert to the manager's mobile phone or computer when the environmental parameters deviate from the optimal range;

[0012] S6. Green pest and disease control: Use biological control methods, release natural enemies to control the number of pests, reduce the use of chemical pesticides, and use biological pesticides and botanical pesticides in combination.

[0013] Preferably, preheating is started from December to January to 16-18℃ at night and 20-22℃ during the day, 18-20℃ at night and 22-26℃ during the budding period, 22-25℃ at night and 30-33℃ during the flowering and young fruiting period, and heating is stopped after the minimum temperature outside the shed stabilizes at above 15℃ in May.

[0014] Preferably, the new energy-saving temperature control facility greenhouse temperature control technology uses air energy for heating or cooling to adjust the temperature, and adopts a greenhouse-in-small greenhouse model. The small greenhouse is 50 cm smaller than the large greenhouse, and an air layer is used in the middle to reduce energy consumption.

[0015] Preferably, high-nitrogen compound fertilizer should be applied before budding, and nitrogen fertilizer should be controlled and appropriate drought should be maintained after the new shoots are pruned. If the tree is too vigorous, spray 300 times of 25% paclobutrazol solution when the new shoots are pruned, and spray 300 times of 25% paclobutrazol solution again after 5-7 days to promote flowering.

[0016] Preferably, during the anthesis stage (when the anthers turn from yellow to white), spray once with 2000 times of 3% gibberellic acid + 2000 times of 0.1 thiobencarb + 800 times of boron fertilizer to ensure fruit growth.

[0017] Preferably, 7-10 days after the first spraying, spray the fruit for the second time: 3.6% benzylamine·gibberellic acid 800 times + 0.1 thiobenzyl alcohol 2000 times + amino acid water-soluble fertilizer to preserve the fruit.

[0018] Preferably, the temperature difference between day and night is regulated at 10-15°C during the fruit color change period and supplemented with red and blue light in a 3:1 ratio. At night, new energy-saving temperature control facilities can be used in greenhouses to control the temperature difference between day and night within the required range.

[0019] Preferably, during the cultivation period, key parameters of the kumquat growth environment are monitored in real time through temperature sensors, humidity sensors, light intensity sensors and soil moisture sensors.

[0020] Preferably, the biological control method uses the release of natural enemies (predatory mites) to control the number of pests such as red spider mites and rust mites, and biological pesticides and botanical pesticides include matrine, azadirachtin and other pesticides that have less impact on the environment and human body.

[0021] Beneficial effects of the present invention:

[0022] 1. The early cultivation method of kumquat realizes the early cultivation of kumquat through precise temperature control, fertilizer management, chemical regulation and artificial adjustment of day and night temperature difference. Specifically: First, precise temperature control can simulate the most suitable environment for the growth of kumquat, so that kumquat can obtain the best growth conditions in various stages such as pre-warming period, budding period, flowering period and young fruit period, thereby advancing its growth cycle and making kumquat fruit mature 1-2 months earlier. Secondly, through pruning and fertilizing management before budding, nitrogen fertilizer adjustment and moderate water control after new shoot self-pruning, and chemical regulation to promote flowering when the tree is too vigorous, it can effectively promote the differentiation of flower buds of kumquat, improve the quantity and quality of flower buds, and lay a solid foundation for the subsequent fruit yield and quality. The fruit preservation treatment carried out during the early stage, by spraying a mixture of gibberellic acid, thiobenzyl and boron fertilizer, and spraying a mixture of 3.6% benzylamine·gibberellic acid, 0.1 thiobenzyl and amino acid water-soluble fertilizer 7-10 days later, can significantly improve the fruit setting rate of kumquat and increase the large fruit rate. Finally, the artificial control of day and night temperature difference and light supplementation measures during the fruit coloring period, using temperature control facilities to actively cool down, and controlling the day and night temperature difference between 10-15°, is conducive to the sugar accumulation and coloring of kumquat fruit, making the fruit brighter in color and better in taste. In summary, the above-mentioned kumquat early cultivation method can not only advance the maturity time of kumquat, increase the large fruit rate and yield, but also improve the quality of the fruit, make the kumquat more in line with market demand, thereby improving economic benefits.

[0023] 2. This method of promoting early cultivation of kumquats, by introducing an intelligent monitoring and automated management system, monitors and precisely manages the growth environment of the kumquats during their cultivation cycle in real time. Multiple sensors work together to ensure that managers can quickly grasp changes in key parameters such as temperature, humidity, light and soil moisture. Once environmental parameters deviate from the optimal range, the system will automatically send an alarm to the manager's mobile phone or computer, so that timely adjustment measures can be taken, effectively preventing growth disorders caused by unsuitable environmental factors. At the same time, the implementation of green pest and disease control strategies, especially the use of biological control methods, such as releasing natural enemies to control the number of pests, and the coordinated use of biological pesticides and botanical pesticides, has significantly reduced the use of chemical pesticides, reduced potential harm to the environment and human body, and improved the yield and quality of kumquats. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 1 The present invention is a flow chart of a method for promoting early cultivation of kumquat. DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 As shown, an embodiment of the present invention provides a method for promoting early cultivation of kumquat, comprising the following steps:

[0027] S1. Heating: During the entire cultivation period, precise temperature control is performed by heating according to the different growth stages of kumquat (pre-warming period, budding period, flowering period and young fruit period) and supplemented with red and blue light in a 3:1 ratio. During this period, new energy-saving temperature control facilities and greenhouse temperature control technology are used;

[0028] S2. Flowering promotion: Prune and fertilize before bud break, adjust nitrogen fertilizer and moderate watering after new shoots are pruned, and use chemical regulation to promote flowering if the tree is too vigorous;

[0029] S3. Fruit preservation: Fruit preservation treatment is carried out during the flowering period. The first spray is a mixture of gibberellic acid, thiobenzyl and boron fertilizer. After 7-10 days, spray a mixture of 3.6% benzylamine·gibberellic acid, 0.1 thiobenzyl and amino acid water-soluble fertilizer.

[0030] S4. Management during the fruit coloring period: artificially control the temperature difference between day and night and use a 3:1 red and blue light supplementary light to supplement the light. Use temperature control facilities to actively reduce the temperature at night. The temperature difference between day and night is controlled between 10-15 degrees.

[0031] S5. Intelligent monitoring and automated management: During the entire cultivation cycle, a variety of sensors are used to monitor the key parameters of the kumquat growth environment in real time. An early warning system is set up to automatically send an alert to the manager's mobile phone or computer when the environmental parameters deviate from the optimal range;

[0032] S6. Green pest control: Use biological control methods, release natural enemies to control the number of pests, reduce the use of chemical pesticides, and use biological pesticides and botanical pesticides in combination;

[0033] By adopting the above technical scheme, the method realizes the early cultivation of kumquat through precise temperature control, fertilizer management, chemical regulation and artificial adjustment of the temperature difference between day and night. Specifically: first, precise temperature control can simulate the most suitable environment for the growth of kumquat, so that the kumquat can obtain the best growth conditions in various stages such as the pre-warming period, the budding period, the flowering period and the young fruit period, thereby regulating its phenological period and making the kumquat fruit mature 1-2 months earlier; secondly, through pruning and fertilizing before budding, nitrogen fertilizer adjustment and moderate water control after new shoot self-pruning, and chemical regulation and flowering promotion when the tree vigor is too vigorous, the flower bud differentiation of kumquat can be effectively promoted, the quantity and quality of flower buds can be improved, and a solid foundation for the subsequent fruit yield and quality can be laid; thirdly, The fruit preservation treatment carried out during the flowering period, by spraying a mixture of gibberellic acid, thiophenecarboxamide and boron fertilizer, and spraying a mixture of 3.6% benzylamine·gibberellic acid, 0.1 thiophenecarboxamide and amino acid water-soluble fertilizer 7-10 days later, can significantly improve the fruit setting rate of kumquat and increase the large fruit rate. Finally, during the fruit coloring period, the temperature difference between day and night is artificially controlled, and the temperature control facilities are used to actively cool down and control the temperature difference between day and night between 10-15°, which is conducive to the sugar accumulation and coloring of the kumquat fruit, making the fruit bright in color and better in taste. In summary, the above-mentioned kumquat early cultivation method can not only advance the maturity time of kumquat, increase the large fruit rate and yield, but also improve the quality of the fruit, make the kumquat more in line with market demand, and thus improve economic benefits.

[0034] During the S1 heating process, preheating should be started from December to January to 16-18℃ at night and 20-22℃ during the day. During the budding period, the temperature should be 18-20℃ at night and 22-26℃ during the day. During the flowering and young fruiting period, the temperature should be 22-25℃ at night and 30-33℃ during the day. When the minimum temperature outside the greenhouse stabilizes above 15℃ in May, heating should be stopped.

[0035] By adopting the above technical scheme, starting from December to January, pre-heating is used to provide a suitable growth environment for kumquats, which helps to break their dormancy and promote early growth. During the budding period, by adjusting the temperature at night and during the day, the best temperature conditions are provided for the budding of kumquats, which is conducive to the neat germination and strong growth of buds. During the flowering period and young fruit period, the temperature at night and during the day is further increased, which is conducive to the opening of flowers, pollination and fertilization, and the early development of fruits, thereby improving the fruit setting rate and fruit quality. The entire regulation process lasts until May. When the minimum temperature outside the greenhouse is stabilized at above 15°C, heating is stopped. This helps the kumquats gradually adapt to the external environment and lays the foundation for subsequent fruit ripening and harvesting. Through precise temperature control and supplementary light, the early growth and development of kumquats can be effectively promoted, the quality and yield of the fruit can be improved, thereby realizing the early cultivation of kumquats.

[0036] During the S1 heating process, the new energy-saving temperature control facility greenhouse temperature control technology uses air energy for heating or cooling to adjust the temperature. It adopts a greenhouse-in-small greenhouse model. The small greenhouse is 50cm smaller than the greenhouse, and an air layer is used in the middle to reduce energy consumption.

[0037] By adopting the above technical scheme, the new energy-saving temperature control facility greenhouse temperature control technology in the pre-heating period, budding period, flowering period, young fruit period and color change period plays a vital role. This technology uses air energy for heating or cooling to adjust the temperature. Through precise temperature control, it provides the most suitable growth environment for kumquat. The small greenhouse is 50cm smaller than the large greenhouse. This design not only helps to maintain the stability of the temperature in the greenhouse, but also uses the air layer to reduce energy consumption. The air layer here plays an insulating role, which can reduce energy loss and thus improve energy utilization efficiency. This design not only ensures the temperature conditions required for kumquat in different growth stages, but also effectively reduces energy consumption. Through precise temperature control, the most suitable environment for kumquat growth can be simulated, thereby promoting the growth and development of kumquat. At the same time, this technology can also avoid the adverse effects of extreme weather on the growth of kumquat, such as high temperature, low temperature, heavy rain, etc.

[0038] During the S2 flowering promotion process, apply high nitrogen compound fertilizer before budding, control nitrogen fertilizer after new shoots are pruned and maintain appropriate drought conditions. If the tree is too vigorous, spray 25% paclobutrazol 300 times solution when new shoots are pruned, and spray 25% paclobutrazol 300 times solution again 5-7 days later to promote flowering;

[0039] By adopting the above technical scheme, high-nitrogen compound fertilizer is applied before budding in order to provide sufficient nutrition for the budding of the kumquat tree and promote the growth and development of new shoots. After the new shoots are pruned, the excessive growth of the new shoots can be inhibited by controlling the application amount of nitrogen fertilizer and appropriately drought, so that more nutrients from the tree can be allocated to flowers and fruits, which is beneficial to preserving flowers and fruits. When the tree vigor is too vigorous, the excessive growth of the new shoots may affect the formation of flower buds. At this time, by spraying 300 times of 25% paclobutrazol solution when the new shoots are pruned and 5-7 days later, the tree vigor can be effectively regulated, and the formation and differentiation of flower buds can be promoted, thereby improving the yield and quality of kumquat. The above measures achieve the purpose of promoting flowers and preserving fruits by comprehensively regulating the nutritional growth and reproductive growth of the kumquat tree.

[0040] During the S3 fruit preservation process, during the anthesis stage (when the anthers turn from yellow to white), spray once with 2000 times of 3% gibberellic acid + 2000 times of 0.1 thiobencarb + 800 times of boron fertilizer to preserve the fruit. 7-10 days after the first spraying, spray the second time: 800 times of 3.6% benzylamine gibberellic acid + 2000 times of 0.1 thiobencarb + amino acid water-soluble fertilizer to preserve the fruit.

[0041] By adopting the above technical scheme, during the flowering period, which is the critical period when the anthers turn from yellow to white, by spraying gibberellic acid and thiophenecarb as plant growth regulators, the adhesion and resistance to shedding of the fruit can be enhanced, thereby reducing fruit drop and increasing the fruit setting rate. Boron fertilizer and amino acid water-soluble fertilizer provide necessary nutrients for kumquat trees. Boron element helps the development of flowers and fruits, while amino acid water-soluble fertilizer can be quickly absorbed and utilized by plants to supplement tree nutrition and promote healthy fruit growth. The fruit preservation treatment measures described in this paragraph are aimed at effectively reducing fruit drop and improving the yield and quality of kumquats through chemical regulation and nutritional supplementation.

[0042] During the S4 fruit coloring period management, the day and night temperature difference is controlled at 10-15℃ during the fruit color change period. At night, the new energy-saving temperature control facility greenhouse can be used to control the day and night temperature difference within the required range and supplement the light with a 3:1 red and blue light supplementary light;

[0043] By adopting the above-mentioned technical solution, regulating the temperature difference between day and night is one of the key measures to improve fruit quality. By artificially controlling the temperature difference between day and night during the fruit coloring period, the fruit can better deposit pigments and accumulate sugars under appropriate temperature fluctuations, thereby improving the color brightness and taste quality of the fruit. Specifically, appropriate temperature difference between day and night can promote the conversion and accumulation of sugar in the fruit, making the fruit sweeter. At the same time, it can also promote the synthesis and distribution of pigments on the fruit epidermis, making the fruit color more attractive.

[0044] S5 intelligent monitoring and automated management uses temperature sensors, humidity sensors, light intensity sensors, and soil moisture sensors to monitor key parameters of the kumquat growth environment in real time during the cultivation cycle;

[0045] By adopting the above-mentioned technical solutions, these sensors can collect accurate data on temperature, humidity, light and soil moisture in real time, helping growers to understand the conditions of the kumquat growth environment in a timely manner. Through data analysis, growers can make more scientific decisions and adjust the environmental conditions of the greenhouse to meet the optimal needs of kumquat growth. Real-time monitoring helps to accurately control the input of agricultural production resources such as irrigation, fertilization and light, and avoid resource waste. For example, by monitoring soil moisture through soil moisture sensors, on-demand irrigation can be achieved, which not only meets the growth needs of kumquats, but also avoids resource waste and soil salinization caused by excessive irrigation, thereby further improving the efficiency and yield of early kumquat cultivation.

[0046] S6 Green pest control uses biological control methods, such as releasing natural enemies (predatory mites) to control the number of pests such as spider mites and rust mites. Biopesticides and botanical pesticides, including matrine and azadirachtin, have less impact on the environment and humans.

[0047] By adopting the above technical solutions, not only the use of chemical pesticides is effectively reduced, and the potential harm to the environment and human body is reduced, but also the ecological balance and biodiversity are promoted. Through the natural predation of natural enemies, the number of pests can be accurately and continuously controlled, and the damage to crops such as kumquat caused by pest outbreaks can be avoided. At the same time, the problem of increased pest resistance caused by excessive use of chemical pesticides is reduced. The use of biological pesticides and botanical pesticides, with their low toxicity and low residue characteristics, further ensures the safety of agricultural products and improves the quality and market competitiveness of crops such as kumquat.

[0048] The technical solution provided by the present invention accurately controls the phenological period of kumquats through advanced energy-saving temperature control facilities, successfully achieving the early maturity of kumquat fruits. Compared with traditional cultivation methods, the fruits can be put on the market 1-2 months earlier. This significant time advantage not only meets the market's urgent demand for early-maturing kumquats, but also avoids the risk of price decline caused by a large number of kumquats being put on the market in the later period. At the same time, precise temperature control is conducive to increasing the yield of kumquats, ensuring that the most suitable environmental conditions can be obtained at each growth stage, significantly improving the large fruit rate, and improving the fruit quality. Through these comprehensive measures, the economic benefits of growers have been significantly improved, and the market competitiveness has also been greatly enhanced.
