Problems solved by technology

[0006] In summary, the problems in the prior art are: At present, the nutrient solution for soilless cultivation of gift watermelon in production uses a formula for the whole growth period of watermelon, and the elements added in different growth periods are the same, which cannot guarantee the nutrient elements required by watermelon in different periods. There are problems such as weak growth at the seedling stage, poor stress resistance, susceptibility to diseases, and slow seedling growth; after flowering, the female flower melon has a small fetus, poor fruit setting ability, easy to melt melon, and slow fruit expansion speed, which seriously affects the yield and fruit quality.

preparation example Construction

[0029] Such as figure 1 Shown, the preparation method of the root nutrient solution of the watermelon coconut bran substrate cultivation different growth period that the embodiment of the present invention provides comprises the following steps:

[0030] S101: Take a certain volume of deionized water, put a certain quality of calcium nitrate, 13% chelated iron, superphosphate, potassium dihydrogen phosphate, magnesium sulfate, potassium nitrate, potassium sulfate, and sodium chloride into the water, and stir until completely dissolved;

[0031] S102: Grind a certain quality of manganese sulfate, boric acid, zinc sulfate, copper sulfate, ammonium molybdate, selenium sulfate, and sodium silicate to powder, add a small amount of deionized water, heat to 30-40°C, fully dissolve, and cool to room temperature Then add 1 to 2 drops of concentrated sulfuric acid to the deionized water for later use;

[0032] S103: dissolving a certain amount of auxin with a small amount of low-alco...

Embodiment 1

[0038] The root nutrient solution of watermelon coco peat matrix cultivation provided by the embodiments of the present invention in different growth stages is composed of the root nutrient solution from seedling stage to flowering and fruit setting and the root nutrient solution from flowering and fruit setting to harvesting.

[0039] The root nutrient solution from the seedling stage to flowering and fruit setting takes deionized water as the content fraction when the solvent is configured 100L:

[0040] Calcium nitrate 80g, 13% chelated iron 2g, calcium superphosphate 15g, potassium dihydrogen phosphate 10g, magnesium sulfate 30g, potassium nitrate 20, manganese sulfate 0.2g, boric acid 0.2g, zinc sulfate 0.02g, copper sulfate 0.05g, molybdenum Ammonium acid 0.01g, potassium sulfate 10g, sodium chloride 15g, selenium sulfate 0.2g, sodium silicate 1g, auxin 2g.

[0041] The root nutrient solution from flowering and fruit setting to harvesting is that the content fraction whe...

Embodiment 2

[0048] The root nutrient solution from the seedling stage to flowering and fruit setting takes deionized water as the content fraction when the solvent is configured 100L:

[0049] Calcium nitrate 100g, 13% chelated iron 4g, calcium superphosphate 20g, potassium dihydrogen phosphate 15g, magnesium sulfate 50g, potassium nitrate 30g, manganese sulfate 0.5g, boric acid 0.5g, zinc sulfate 0.05g, copper sulfate 0.1g, molybdenum Ammonium acid 0.02g, potassium sulfate 15g, sodium chloride 20g, selenium sulfate 0.5g, sodium silicate 3g, auxin 5g.

[0050] The root nutrient solution from flowering and fruit setting to harvesting is that the content fraction when the solvent is configured 100L with deionized water is:

Abstract

The invention belongs to the technical field of fertilizers and preparation of fertilizers, and discloses a root nutrient solution for cultivation of watermelons by a coco coir substrate in differentgrowth periods and a preparation method of the root nutrient solution. The root nutrient solution for cultivation of the watermelons by the coco coir substrate comprises the following components: calcium nitrate, 13% chelated iron, calcium superphosphate, potassium dihydrogen phosphate, magnesium sulfate, potassium nitrate, manganese sulfate, boric acid, zinc sulfate, copper sulphate, ammonium molybdate, potassium sulfate, sodium chloride, selenium sulphate, sodium metasilicate and auximone. In the earlier stage of growth of small watermelons, a nutrient solution formula in the first stage isused, and is mainly used for promoting nutrition growth, root systems of plants are developed, the plants grow robustly, and disease resistance is high; and in a blooming and fruit bearing stage, a nutrient solution formula in the second stage is used, the content of microelements is increased, absorption of fruits to the microelements is promoted, after the nutrient solution formula is used, human immunity can be enhanced, moreover, small watermelons of female flowers can be large, abortion is not caused easily, and the fruit expanding speed is increased obviously.

Description

technical field [0001] The invention belongs to the technical field of fertilizers and fertilizer manufacturing, and in particular relates to a root nutrient solution for different growth stages of watermelon coconut bran substrate cultivation and a preparation method thereof. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: the current production is carried out in soilless cultivation of gift small watermelons, and one formula is used for the whole growth period, and different nutrient solutions are not adjusted according to different growth periods. This results in weak growth at the seedling stage, poor stress resistance, susceptibility to diseases, and slow seedling growth; after flowering, the female flower melon has a small fetus, poor fruit setting ability, easy melon digestion, and slow fruit expansion speed, which seriously affects the yield and fruit quality. [0003] The formula of watermelon nutrient s...
