Description

Technical Field

[0001] The invention mainly relates to the technical field of cucumber cultivation, and specifically relates to a dwarfing and strong seedling cultivation method of hydroponic cucumbers and a cultivation device thereof. Background Art

[0002] The plant type characteristics of cucumber have an important impact on its yield and benefits. The concept of "ideal plant type" was first proposed by Donald in 1968. It should have the characteristics of short vines and shortened internodes, which helps to save greenhouse space and improve land use efficiency. However, most of the cucumber varieties currently in production have long vines, long internodes, and tall plants, which require a large cultivation space. This not only affects the ventilation and light transmission in the greenhouse, but also increases production costs and labor, and reduces the yield of cucumbers. Therefore, creating a dwarf and compact plant type can not only increase the planting density, but also help to achieve one-time mechanized harvesting. At present, the main methods to prevent cucumbers from growing too tall are temperature control, water and fertilizer management, physical measures, and the application of plant growth regulators.

[0003] The above methods all have certain problems in actual production applications. Among them, the temperature control method requires precise equipment and technical support, which is easy to increase production costs, and may affect the control effect under extreme weather conditions. The water and fertilizer management method requires accurate calculation of the amount of water and fertilizer and the supply frequency, which increases the difficulty of cultivation management and may have a certain impact on the root growth and yield of cucumbers. The physical measure method mainly weakens the apical dominance of the plant by adjusting physical measures such as hanging vines, pruning branches, and pinching heads. This method has certain operational difficulties and is easy to cause certain damage to the cucumber plant, affecting its normal growth and yield. The application of plant growth regulators is effective in inhibiting the excessive growth of cucumbers. However, the use of plant growth regulators may have a certain impact on the environment and easily lead to residual plant hormones in fruits and vegetables. Therefore, exploring a safe and residue-free seedling method to effectively inhibit the excessive growth of cucumbers has become a technical difficulty that needs to be solved urgently. Summary of the invention

[0038] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] The following describes an embodiment of the present invention based on its overall structure. Example

[0040] Please refer to the attached Figure 1 , 2 As shown, in a preferred embodiment of the present invention, a method for cultivating dwarf and strong seedlings of hydroponic cucumbers comprises the following steps:

[0041] Step 1, pre-soaking cucumber seeds; soaking the cucumber seeds in a 10% sodium hypochlorite solution for 10 minutes, and after soaking, washing the surface of the seeds with clean water to obtain seed 1;

[0042] Step 2, germination of cucumber seeds: Place filter paper on the bottom of the culture dish and add clean water, place seed 1 on the filter paper, put it into a constant temperature incubator and germinate the seed 1 at 25 degrees Celsius plus or minus 1 degree Celsius;

[0043] Step 3: hydroponically cultivate cucumber seeds. Wrap the seeds in a moist sponge after they turn white in a constant temperature incubator. Place the sponge wrapped with the seeds in a hydroponic box 10, and introduce clean water into the hydroponic box 20 for hydroponic cultivation.

[0044] Step 4: hydroponics of cucumbers; when the seeds in the sponge grow to fully unfolded cotyledons, the cucumber plants are planted on the foam board and placed in the hydroponic box 10, and the garden test nutrient solution is passed into the hydroponic box 20 for hydroponic cultivation;

[0045] The EC of the nutrient solution for the garden test is 1.2 dS / m. The formula of the nutrient solution for the garden test is: macroelements: 472 mg / L Ca(NO3)2·4H2O, 404 mg / L KNO3, 77 mg / L NH4H2PO4, 247 mg / L MgSO4·7H2O; trace elements: 23.6 mg / L Fe-DETA, 2.86 mg / L H3BO3, 2.11 mg / L MnSO4·4~5H2O, 0.22 mg / L ZnSO4·7H2O, 0.08 mg / LCuSO4·5H2O, 0.02 mg / L Na2MoO4·2H2O;

[0046] When the garden test nutrient solution was hydroponically cultivated, the pH value was maintained at 7.0, and the cucumber plants were placed in a human environment with a light intensity of 16,000 lux and a temperature of 26°C for 12 hours during the day and a temperature of 16°C for 12 hours at night. Oxygen was pumped in 3 times a day for 5 minutes each time, and the garden test nutrient solution was replaced every 7 days.

[0047] Step 5, replacement of culture solution; when the cucumber plant grows to two leaves and one heart, the garden test nutrient solution in the hydroponic box 20 is replaced with the GG nutrient solution to continue the hydroponic culture, and the GG nutrient solution is replaced every five days during the cultivation period;

[0048] When preparing the GG nutrient solution, take 6.5-26.0 mL of 77% glycerol glucoside in 1L of pure water, stir with a magnetic stirrer at 25°C for 30 minutes, and after fully mixing, prepare a GG mother solution with a concentration of 5-20 mL / L. According to the ratio of 1:99, take 5-20 mL / L of the GG mother solution and mix it into the garden test nutrient solution. After fully mixing, prepare a GG nutrient solution with a concentration of 0.05 mL / L-0.2 mL / L.

[0049] The glycerol glucoside concentration of the GG nutrient solution was 0.2 mL / L;

[0050] When replacing the nutrient solution, the waste liquid in the hydroponic box 20 is discharged, the lifting component 21 on the hydroponic box 20 lifts up the hydroponic box 10, and the cleaning liquid is input from the input end of the hydroponic box 20 to flush the hydroponic box 20. After a unit of flushing time, the rinsing component 24 at the execution end of the lifting component 21 drives the hydroponic box 10 to rise and fall to rinse the roots of the plants. After the rinsing is completed, new nutrient solution is input from the input end of the hydroponic box 20 to complete the replacement of the nutrient solution.

[0051] It should be noted that, in this embodiment, 6.5 mL, 13.0 mL, 26.0 mL, and 64.9 mL of 77% GG were respectively taken into 1L of pure water, stirred for 30 min with a magnetic stirrer at 25°C, and fully mixed to prepare GG mother solutions with concentrations of 5.0 mL / L, 10.0 mL / L, 20.0 mL / L, and 50 mL / L, where GG is glycerol glucoside.

[0052] According to the ratio of 1:99, 5.0 mL / L, 10.0 mL / L, 20.0 mL / L, and 50 mL / L of GG mother solution were mixed into the garden test nutrient solution. After thorough mixing, GG nutrient solutions with concentrations of 0.05 mL / L, 0.1 mL / L, 0.2 mL / L, and 0.5 mL / L were prepared.

[0053] The cucumbers were hydroponically cultivated using the GG nutrient solution, and the cucumbers were hydroponically cultivated using the garden test nutrient solution without GG as the control (CK). After 20 days of cultivation, the aboveground and underground properties of the cucumbers were measured. The results are shown in Tables 1, 2, 3, and 4.

[0054] Table 1: Effects of different concentrations of GG on the growth of hydroponic cucumber

[0055] Table 2: Effects of different concentrations of GG on the biomass of hydroponic cucumber leaves

[0056] Table 3: Effects of different concentrations of GG on the biomass of hydroponic cucumber stems

[0057] Table 4 Effects of different concentrations of GG treatment on root biomass of hydroponic cucumber

[0058] The results showed that the response of all parts of cucumber to GG was concentration-dependent, that is, after exceeding a specific threshold, the growth indicators of cucumber showed a reversal trend. In general, low concentrations of GG (0.05 mL / L and 0.1 mL / L) promoted the growth of cucumber, while high concentrations of GG (0.5 mL / L) showed a significant inhibitory effect. The 0.05 mL / L GG treatment significantly increased the stem diameter, stem fresh weight, leaf dry weight and root fresh weight of cucumber; under the 0.1 mL / L GG treatment, the stem diameter and root fresh weight of cucumber also increased significantly. However, when the GG concentration increased to 0.5 mL / L, except for the chlorophyll content and leaf dry matter content, which remained unchanged and the root dry matter content increased, the other indicators were inhibited.

[0059] The 0.2 mL / L GG treatment significantly reduced the plant height of cucumber, but did not affect the growth of stem diameter. In addition, under this concentration treatment, the chlorophyll content, leaf dry matter content, and stem dry matter content of cucumber were not significantly different from those of CK, and the root dry matter content was higher than that of CK.

[0060] These results show that when the GG concentration is less than 0.2 mL / L, the addition of GG has a significant promoting effect on cucumber growth and has a positive regulatory effect on improving the seedling index of hydroponic cucumbers; when the GG concentration is 0.2 mL / L, the GG treatment not only maintains the photosynthesis and nutrient accumulation of cucumber seedlings, but also significantly reduces the plant height. Therefore, in actual application production, according to the actual growth of the plants and target requirements, a GG nutrient solution with a concentration of 0.05-0.2 mL / L can be selected for cucumber cultivation.

[0071] During cultivation, the cucumber seeds are immersed in a sodium hypochlorite solution with a concentration of 10% for 10 minutes, and after the immersion is completed, the surface of the seeds is rinsed with clean water, filter paper is spread on the bottom of the culture dish and clean water is added, the seeds are placed on the filter paper, and the culture dish is placed in a constant temperature incubator and the seeds are germinated at a temperature of 25 degrees Celsius plus or minus 1 degree Celsius; the seeds in the constant temperature incubator are wrapped in a moist sponge after turning white, the sponge wrapped with the seeds is placed in a hydroponic box 10, and clean water is passed into the hydroponic box 20 to perform hydroponic culture; when the seeds in the sponge grow to the point where the cotyledons are fully unfolded, the cucumber plants are planted on a foam board and placed in the hydroponic box 10, and a garden test nutrient solution is passed into the hydroponic box 20 to perform hydroponic culture. Carry out hydroponic cultivation; when the cucumber plant grows to two leaves and one heart, the garden test nutrient solution in the hydroponic box 20 is replaced with the GG nutrient solution to continue the hydroponic cultivation. The GG nutrient solution is replaced every five days during the cultivation period; when the nutrient solution is replaced, the waste liquid in the hydroponic box 20 is discharged through the drain assembly 233, the lifting component 21 on the hydroponic box 20 lifts the hydroponic box 10, and the liquid supply assembly 232 inputs the cleaning liquid to flush the hydroponic box 20. After the flushing unit time, the rinse component 24 at the execution end of the lifting component 21 drives the hydroponic box 10 to rise and fall to rinse the roots of the plants. After the rinse is completed, the liquid supply assembly 232 inputs new nutrient solution to complete the replacement of the nutrient solution;

[0072] The liquid supply pipe 2322 in the liquid supply assembly 232 can be connected to the clean water supply system, the garden test nutrient solution supply system and the GG nutrient solution supply system respectively, so as to supply the required liquid into the hydroponic box 20. When supplying, the valve on the liquid supply pipe 2322 is opened, and the liquid enters the hydroponic box 20 through the liquid supply pipe 2322, the diversion pipe 2321 and the supply pipe 2323;

[0073] When the drain assembly 233 is working, the valve on the discharge pipe 2334 at the end of the hydroponic box 20 is opened, and the waste liquid can be discharged through the discharge pipe 2334 at the end of the hydroponic box 20. The actuator end of the electric cylinder 2333 drives the L-shaped valve plate 2332 to move, so that the auxiliary drain box 2331 is connected with the hydroponic box 20, and the liquid can be discharged through all the discharge pipes 2334 to prevent the waste liquid from flowing back during flushing;

[0074] When the lifting component 21 is working, the execution end of the power cylinder 212 drives the annular frame 22 to move up and down;

[0075] When the rinsing component 24 is working, the driving end of the driving motor 247 drives one of the power gear discs 245 to rotate, and one of the power gear discs 245 drives the other power gear discs 245 to rotate through the transmission gear disc 246. When the power gear disc 245 rotates, it drives the driven rotating disc 243 to rotate. During the rotation of the driven rotating disc 243, the transmission shaft 244 slides in the slide groove 2421 and drives the n-shaped lifting frame 242 to move up and down along the n-shaped slide rail frame 241. The n-shaped slide rail frame 241 drives the hydroponic box 10 to move up and down to produce a rinsing effect;

[0076] When the scrubbing slow-flow component 25 is working, the first slow-flow plate 252 and the second slow-flow plate 253 realize the slow flow of the flushing liquid, and during the slow flow process, the water flow is guided backflow through the arc-shaped part of the plate body to protect the plant roots. At the same time, the first liquid flow groove 2521 facilitates the rapid passage of water that deviates from the plant root system, and the second liquid flow groove 2531 facilitates the rapid passage of the rinse water flow passing through the plant root system.
