Description

Technical Field

[0001] This invention relates to the field of cherry tomato cultivation technology, and in particular to a method for dwarfing and dense planting of cherry tomatoes in arched greenhouses. Background Technology

[0002] Cherry tomatoes (Lycopersicon esculentum var. cerasiforme A.Gray) are cultivated varieties of the genus Lycopersicon in the Solanaceae family. They are annual or perennial vine-like herbaceous plants. Cherry tomatoes are small fruits, small in size, sweet in taste, and rich in nutrients. They contain a large amount of vitamin C, vitamin E, carotene, calcium, phosphorus, and other nutrients. They have the effects of quenching thirst and beautifying the skin, making them one of the most popular fruits. They have good edible and ornamental value.

[0003] Plant height, representing plant architecture, is one of the important agronomic traits affecting crop yield, and the selection of ideal plant architecture is an important way to achieve simplified cultivation. Dwarfing treatment can reduce plant height, reduce labor costs for vine training and plant damage, increase the number of cherry tomatoes in the limited height of the facility, ensure yield and improve fruit quality. Recent studies have found that plant growth inhibitors can effectively control excessive crop growth, promote reduced plant height, thicker stems, faster fruit formation, and increased yield. Commonly used plant growth inhibitors are mainly divided into three categories: First, triazole growth regulators, represented by paclobutrazol and uniconazole, are characterized by strong efficacy and rapid effect, but are prone to over-controlling growth or causing phytotoxicity; second, quaternary ammonium salt growth regulators, represented by mepiquat chloride and chlormequat chloride, are characterized by mild efficacy, but slow effect and poor growth control when the dosage is too small; and the third category is a new type of plant growth regulator—calcium cyclamate. Calcium cyclamate can effectively shorten internode length, increase chlorophyll content, enhance photosynthesis, promote flower bud differentiation, improve fruit setting rate, promote fruit enlargement, and enhance sweetness and coloring. Furthermore, calcium cyclamate is an excellent growth regulator that controls foliage without controlling flowering and fruiting, has low toxicity, and hardly affects subsequent crops. In contrast, various pesticides, including paclobutrazol and other growth regulators, have higher toxicity, larger residue levels, and longer residual periods. Therefore, calcium cyclamate has good application prospects for plant dwarfing treatment. However, calcium cyclamate is expensive, has a short half-life, and is easily decomposed and inactivated. Spraying calcium cyclamate using conventional methods results in rapid decomposition and inactivation, and multiple sprays increase labor and financial costs. Summary of the Invention

[0004] Based on the above-mentioned technical problems, the purpose of this invention is to provide a method for dwarfing and dense planting of cherry tomatoes in arched greenhouses, which solves the problem that calcium cyclamate is easily decomposed and ineffective after being applied in conventional methods, thus reducing its effectiveness.

[0005] The present invention solves the above-mentioned technical problems through the following technical means:

[0006] A method for cultivating dwarf and densely planted cherry tomatoes in arched greenhouses, the method comprising the following steps:

[0007] (1) Seedling cultivation: Mix peat moss, vermiculite and perlite in a mass ratio of 7:2:1 to obtain a substrate, fill it into a seedling tray, and then sow cherry tomatoes in the seedling tray filled with substrate for seedling cultivation. When the seedlings grow to 3-4 true leaves, they are transplanted.

[0008] (2) Transplanting and planting: From late March to early April, after preparing the land and making ridges in the arched greenhouse, the seedlings are transplanted and planted.

[0009] (3) Dwarfing treatment: Spray the growth regulator at a rate of 6-15 kg / mu before the cherry tomatoes bloom to carry out dwarfing treatment;

[0010] (4) Pruning: The three-stem pruning method is used to prune the main vine, retaining the lateral branches at the first and second flower nodes of the main vine, and removing the remaining lateral branches to increase the number of fruits and reduce the weight of a single fruit.

[0011] (5) Stage dynamic water control: Reduce the amount of watering before harvesting each bunch of fruit to control water content and increase the soluble solids content of the fruit.

[0012] (6) Harvesting: Harvest in batches according to the ripeness of the fruit.

[0013] Furthermore, the regulator comprises the following raw materials:

[0014] Calcium cyclohexane, polyvinyl alcohol, 2,5-dihydroxybenzoic acid, coconut oil, asparagine, p-toluenesulfonic acid.

[0015] Furthermore, the method for preparing the regulator is as follows:

[0016] A: After heating coconut oil to 30°C and stirring to melt it, add calcium cyclohexane and homogenize it at 30°C and 800-1200 r / min for 10-15 min. Then, place it at 4°C to solidify it, grind and sieve it to obtain encapsulated microparticles.

[0017] B: Dissolve polyvinyl alcohol in water to prepare a 2wt% polyvinyl alcohol solution. Add asparagine and p-toluenesulfonic acid to the polyvinyl alcohol solution, heat to 40-50℃ and stir for 4-6 hours. After the reaction is complete, adjust the pH to 8.5-9.5, then add 2,5-dihydroxybenzoic acid, stir at room temperature for 1-2 hours, then heat to 75-85℃ and stir for 10-20 minutes to obtain a mixed solution. Place the embedded microparticles and the mixed solution into a homogenizer and homogenize at 10℃ and 800-1200 r / min for 10-15 minutes to obtain a regulator.

[0018] Furthermore, in step A, the mass ratio of coconut oil to calcium cyclohexane is (1-2):(0.06-0.1).

[0019] Furthermore, in step B, the mass ratio of polyvinyl alcohol solution, asparagine, p-toluenesulfonic acid, and 2,5-dihydroxybenzoic acid is (6-14):(0.05-0.07):(0.01-0.02):(0.06-0.08).

[0020] Furthermore, in step B, the mass ratio of the mixed adhesive solution to the embedded microparticles is (6-14):(1-2).

[0021] Furthermore, the planting operation in step (2) is as follows:

[0022] After tilling the soil inside the arched greenhouse, apply 3000-5000 kg / mu of well-rotted livestock and poultry manure, and then apply earthworm castings and oil cake residue at a rate of 200 kg / mu. Then, make ridges, aligning the ridges with the longitudinal direction of the arched greenhouse. The center-to-center spacing of the ridges should be 1.6 m, the bottom width of the ridges should be 60-70 cm, the top width of the ridges should be 40-50 cm, and the height of the ridges should be 15-20 cm. Then, plant the seedlings in double rows at a density of 2500-2800 plants / mu.

[0023] Furthermore, the specific dynamic water control operation in step (5) is as follows:

[0024] Before the first fruit set, water thoroughly to maintain a relative soil moisture content of 75%–85%. Then, 5–7 days before harvesting each fruit cluster, reduce watering to maintain a relative soil moisture content of 50%–60%.

[0025] Furthermore, the cultivation temperature inside the cherry tomato greenhouse is 25–35°C during the day and 16–18°C at night.

[0026] Calcium cyclamate has a short half-life and is easily decomposed rapidly in the soil, losing its efficacy. Direct spraying of calcium cyclamate using conventional methods significantly shortens its action time and reduces its effectiveness, while multiple sprays greatly increase labor and financial costs. Therefore, this invention prepares calcium cyclamate into a long-acting regulator for treating tomato plants. Combined with cultivation methods, this reduces internode length and single fruit weight, increases fruit set and soluble sugar content, and achieves high-quality cherry tomato cultivation.

[0027] Specifically, this invention first uses coconut oil to encapsulate the active ingredient calcium cyclamate into encapsulated microparticles. These microparticles are then mixed and homogenized with polyvinyl alcohol (PVA) adhesive to disperse within the PVA solution. When the regulator is sprayed, the PVA solution, being viscous, carries the encapsulated microparticles and allows them to adhere well to the plant's leaf surface. Meanwhile, the coconut oil melts and releases the encapsulated calcium cyclamate at daytime cultivation temperatures above 25°C, allowing the tomato plant to absorb and utilize it. At night, when the temperature drops below 18°C, the coconut oil solidifies, re-encapsulating and fixing the calcium cyclamate. Through repeated melting and solidification of the coconut oil, the calcium cyclamate is fixed within the regulator system, inhibiting its loss. This effectively protects the calcium cyclamate while allowing it to be slowly released over a long period to act on the tomato plant, extending its duration of action, enhancing its efficacy, and reducing the frequency of application, thereby reducing labor and financial costs.

[0028] To fully utilize the effect of calcium cyclamate in the embedded microparticles, this invention first treats polyvinyl alcohol (PVA) with asparagine to adjust the molecular structure of PVA and enhance the hydrogen bonding between PVA and the coconut oil embedded in the microparticles. This ensures that the embedded microparticles are continuously and stably dispersed in the PVA solution. Furthermore, 2,5-dihydroxybenzoic acid is added to react and combine with PVA, increasing the interaction between PVA and the leaf surface, thereby improving the adhesion of the PVA solution to the leaf surface. By adjusting the interaction between the PVA solution and the coconut oil embedded in the microparticles, as well as between the PVA solution and the plant leaves, the regulator can be continuously and stably attached to the surface of the tomato plant and release calcium cyclamate during the day when the coconut oil melts, effectively inhibiting gibberellin synthesis, reducing internode length, and increasing fruit set rate.

[0029] Beneficial effects:

[0030] 1. This invention cultivates cherry tomatoes in a large arched greenhouse. During the cultivation process, methods such as double-row dense planting, staged water control, and treatment with regulators are used to dwarf the tomato plants. Within the limited height of the greenhouse, the number of fruit clusters is increased, the fruit set is improved, and the weight of individual fruits is reduced. While ensuring yield, the soluble sugar content can be increased, thereby achieving high-quality cultivation of cherry tomatoes, which has good development prospects.

[0031] 2. This invention uses a specific method to prepare the growth regulator calcium cyclamate into a growth regulator, which can be sprayed onto cherry tomato plants. This effectively inhibits the decomposition and inactivation of calcium cyclamate, prolongs the action time, enhances the effect, and reduces manpower and financial costs, thus showing good application prospects.

[0059] Example 4: Dwarf and High-Density Cultivation Method for Cherry Tomatoes in Arched Greenhouses

[0060] (1) Seedling cultivation: Mix peat moss, vermiculite and perlite in a mass ratio of 7:2:1 to obtain a substrate, fill it into a seedling tray, and then sow cherry tomatoes in the seedling tray filled with substrate. Manage the seedlings according to conventional methods. When the seedlings have grown to 3-4 true leaves, transplant them.

[0061] (2) Transplanting and planting: In early April, after tilling the soil in the greenhouse, apply 4000 kg / mu of well-rotted livestock and poultry manure, and then apply earthworm castings and oil cake residue at a rate of 200 kg / mu respectively. After ridging, the ridges should be aligned with the longitudinal direction of the greenhouse, with a center-to-center spacing of 1.6 m, a bottom width of 60 cm, a top width of 40 cm, and a height of 15 cm. When transplanting, plant in double rows with a plant spacing of about 30 cm, with a planting density of 2800 plants / mu. Maintain a daytime temperature of 26℃ and a nighttime temperature of 17℃ in the greenhouse.

[0062] (3) Dwarfing treatment: Before the cherry tomatoes bloom, spray the regulator prepared according to the method in Example 1 at a rate of 8 kg / mu;

[0063] (4) Pruning: The three-stem pruning method is used to prune the main vine, retaining the lateral branches at the first and second flower nodes of the main vine, and removing the remaining lateral branches to increase the number of fruits and reduce the weight of a single fruit.

[0064] (5) Stage dynamic water control: Before the first fruit set, water thoroughly to maintain the relative soil moisture content of about 80%. Five days before harvesting the fruit, reduce the amount of watering to maintain the relative soil moisture content of 55% in order to increase the soluble solids content of the fruit.

[0065] (6) Harvesting: Harvest in batches according to the ripeness of the fruit.

[0066] Experiment: High-density, dwarfing, and high-sugar cultivation method for cherry tomatoes

[0067] 1. Experimental Methods: The growth regulators prepared in Example 1 and Comparative Examples 1-5 were used in a greenhouse cherry tomato cultivation experiment in Jinji Town, Litong District, Wuzhong City, Ningxia. The experiment was divided into 9 groups: experimental group 1, control groups 1-7, and blank control group. The growth regulators and cultivation methods used in each group are as follows:

[0068] Experimental group 1: The regulator of Example 1 and the cultivation method of Example 4 were used;

[0069] Control groups 1-5: The regulators used in comparative examples 1-5 and the cultivation method of Example 4 were used respectively;

[0070] Control group 6: The plant growth regulator prepared in Example 1 was used, and the planting density was reduced to 2200 plants / acre at transplanting time. The remaining steps were the same as in Example 4.

[0071] Control group 7: The regulator prepared in Example 1 was used, and no staged water control was carried out during cultivation; instead, the soil moisture content was maintained at 80%.

[0072] Blank control group: No regulator was sprayed, but water was sprayed instead. The planting density was 2200 plants / acre. No stage water control was carried out, but the soil moisture content was kept at 80%. The remaining cultivation steps were the same as in Example 4.

[0073] 2. Results detection: The number of cherry tomatoes set in each group was recorded. After harvest, the internode length (distance between 9 and 10 leaves) of each tomato plant was measured, as well as the weight of a single fruit, soluble solids, and soluble sugar content. The experiment was repeated three times, and the average data are shown in Table 1.

[0074] Table 1

[0075]

[0076] Based on the data analysis in Table 1, we can conclude that:

[0077] (1) Cultivating cherry tomatoes according to the method of the present invention can effectively reduce the internode length of the plant, reduce the weight of a single fruit, increase the number of fruits set, increase the content of soluble solids and soluble sugar, and can better realize the development of high-quality cherry tomato fruits.

[0078] (2) In control group 1, the regulator was not prepared by encapsulating calcium cyclamate with coconut oil, resulting in a large amount of loss and ineffectiveness of the active ingredient, calcium cyclamate, leading to poor efficacy and increased internode length in tomatoes, which further affected the fruit set rate. In control group 2, the regulator was not prepared by treating polyvinyl alcohol with asparagine, which reduced the fixation effect of the polyvinyl alcohol solution on the encapsulated microparticles in coconut oil, leading to an increased loss of internal calcium cyclamate, reduced efficacy, higher internode length, and lower fruit set rate. In control group 3, the regulator was not prepared by treating polyvinyl alcohol with 2,5-dihydroxybenzoic acid, resulting in poor adhesion of polyvinyl alcohol to the leaf surface, leading to loss and ineffectiveness of the regulator and reduced efficacy. In control group 4, the regulator was prepared by adjusting the pH to 7, which reduced the stability of calcium cyclamate under neutral conditions, thus reducing its efficacy. In control group 5, the regulator was prepared by directly placing the encapsulated microparticles in water, which made the regulator easily lost from the leaf surface, greatly reducing the efficacy of the active ingredient, calcium cyclamate.

[0079] (3) In control group 6, the planting density of cherry tomatoes was reduced and the weight of single fruit increased; in control group 7, no water control was carried out during the cultivation of cherry tomatoes, but the substrate soil was kept at a high moisture content, and the content of soluble solids and soluble sugar in the fruit decreased significantly.

[0080] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications and substitutions should be covered within the scope of the claims of the present invention.
