Description

Technical Field

[0001] The present invention relates to the technical field of fertilizers, and in particular, to a water-soluble fertilizer for tomatoes, a preparation method and application thereof, and a tomato planting method. Background Art

[0002] During tomato planting, it is very easy to occur or happen that the fruit color change is slow or the coloring is poor, which directly affects the fruit quality and commerciality of tomato agricultural products, and causes a relatively serious impact on planting. The main reasons are environmental temperature and nutrient deficiency.

[0003] First of all, in terms of temperature, when tomatoes enter the mature green stage, the chlorophyll content is relatively high and the carotenoid content is relatively low. Lycopene is easily formed under the condition of air temperature of 18°C - 26°C. When the temperature is higher than 32°C, the fruit grows and matures faster, but the formation of lycopene is blocked, which also affects coloring. High-temperature weather will inactivate the chlorophyll of plants, reduce the photosynthesis speed of plants, inhibit plant photosynthesis, reduce the generation and accumulation of sugars, and also harm flower bud differentiation, promote the increase of male flowers, and reduce the number of female flowers. At the same time, high temperature will continue to affect the pollen activity, resulting in difficult pollination or uneven pollination of female flowers, an increase in small fruits and deformed fruits of fruits and vegetables. In addition, high temperature will not only cause the proteins in tissue cells to coagulate and denature, resulting in irreversible damage, but also easily cause diseases in fruits and vegetables, such as the occurrence of mosaic, streak, and small leaves in the main stem, the shrinkage, deformation of fruits and vegetables, and the loss of commercial value.

[0004] Secondly, in terms of nutrition, when there is too much nitrogen fertilizer, the growth potential of the plant is strong, but when the water is insufficient, uneven coloring of the fruit shoulder is likely to occur; when nitrogen is deficient, the fruit shoulder shows yellow. When potassium is deficient, the fruit shoulder is yellowish green and the vascular bundles in the fruit heart are lignified. When boron is deficient, the fruit shoulder remains green with necrotic spots and has corky cracks on the surface. When calcium is deficient, the skin of the fruit shoulder is thin and easy to open and rot, and physiological diseases such as blossom end rot and fruit cracking are likely to occur in the fruit.

[0005] Generally, when planting tomatoes, in case of high-temperature weather or nutrient deficiency, when it is not easy to change color or physiological diseases such as deformity and blossom end rot occur, the whole plant is generally sprayed with plant regulators or foliar fertilizers, or the fruits are directly ripened after picking to improve the commerciality of tomatoes and achieve early listing of tomatoes. However, in the implementation process, it is very difficult to control the operation timing and dosage. Excessive amount or residue on the leaves is very easy to cause the withering of the plant, the operation is inconvenient, and it is easy to produce phytotoxicity and fertilizer damage, which is not conducive to the commerciality and healthy implementation of healthy tomato products.

[0006] In view of this, the present invention is specifically proposed. Summary of the Invention

[0037] In some preferred embodiments, the water-soluble tomato fertilizer comprises 15 parts of urea, 17 parts of industrial monoammonium phosphate, 60 parts of potassium nitrate, 2 parts of magnesium sulfate, 2 parts of gallium ethylenediaminetetraacetate, 1 part of boric acid, 0.5 part of zinc sulfate, 0.2 - 0.5 part of methyl jasmonate and 0.5 - 1 part of chromogenic amine.

[0038] In some more preferred embodiments, the water-soluble tomato fertilizer comprises 15 parts of urea, 17 parts of industrial monoammonium phosphate, 60 parts of potassium nitrate, 2 parts of magnesium sulfate, 2 parts of gallium ethylenediaminetetraacetate, 1 part of boric acid, 0.5 part of zinc sulfate, 0.5 part of methyl jasmonate and 1 part of chromogenic amine.

[0041]

[0042] Among them, methyl jasmonate can induce plants to produce defense substances to improve the stress resistance of crops. For example, betaine, soluble sugar substances and proline, etc. as important cell osmotic adjustment substances, can reduce the osmotic potential of cells. At the same time, the content and activity of superoxide dismutase, catalase, peroxidase and non - enzymatic antioxidants increase rapidly, clearing the excess reactive oxygen free radicals in the plant body. Exogenous MeJA promotes the degradation of chlorophyll, the synthesis of carotenoids and anthocyanins in the fruit peel by increasing the release of ethylene in the crop, improving the color of the fruit, improving the quality of the fruit, enabling the crop to be listed earlier, and increasing the benefits of growers.

[0043] The molecular formula of chromogenic amine (CPTA) is C 12 H 19 Cl2NS, which is a synthetic growth hormone. It is absorbed and conducted through the leaves and the fruit epidermis, can promote the synthesis of carotenoids, and at the same time can also enhance the gloss of fruits.

[0044] Continuing from the above, the water-soluble fertilizer for tomatoes provided by this application rationally allocates macro and micro elements such as nitrogen, phosphorus, potassium, calcium, magnesium, zinc, and boron according to the physiological demand characteristics during the fruit swelling period of tomatoes, and can meet the fertilizer requirement ratio during the fruit swelling period of tomatoes (nitrogen:phosphorus:potassium = 1:0.2:1.7); at the same time, it adds amidochrome that can adjust the color-changing metabolism during the fruit swelling period, which can promote color change during the fruit setting and swelling period of tomato planting, and make its function and color-changing effect tend to be coordinated by strictly controlling the addition ratio; by adding methyl jasmonate, it can enhance the ability of tomatoes to cope with stress environments such as high temperature, and play a role in improving the color-changing quality and increasing the yield of tomatoes.

[0045] Correspondingly, this application also provides a preparation method for the above-mentioned water-soluble fertilizer for tomatoes, including the following steps: mixing each raw material according to the ratio.

[0046] In addition, this application also provides the application of the above-mentioned water-soluble fertilizer for tomatoes, which is used for fertilizing tomatoes during the planting process.

[0047] Correspondingly, this application also provides a tomato planting method, which includes the following steps: after applying the base fertilizer, apply the above-mentioned water-soluble fertilizer for tomatoes independently once during the flowering and fruiting period, young fruit period, fruit swelling period, and harvesting period, and the amount of each fertilization is 25 - 30 kg / mu.

[0048] For reference, the amount of each fertilization can be 25 kg / mu, 26 kg / mu, 27 kg / mu, 28 kg / mu, 29 kg / mu, or 30 kg / mu, etc., or any other value within the range of 25 - 30 kg / mu. Preferably, the amount of each fertilization is 25 kg / mu.

[0049] Specifically, the above-mentioned water-soluble fertilizer for tomatoes is applied by drip irrigation.

[0050] During drip irrigation, the mass ratio of the water-soluble fertilizer for tomatoes to water can be 1:550 - 650, such as 1:550, 1:560, 1:570, 1:580, 1:590, 1:600, 1:610, 1:620, 1:630, 1:640, or 1:650, etc., or any other value within the range of 1:550 - 650. Preferably, during drip irrigation, the mass ratio of the water-soluble fertilizer for tomatoes to water is 1:600.

[0051] Through the above method, it can enhance the ability of tomatoes to cope with stress environments (such as high-temperature weather) during the process of tomato fruiting, can improve and change the color-changing effect by promoting the synthesis rate of lycopene, reduce physiological diseases such as deformity and blossom-end rot, and thus improve the quality of tomato products.
