Water-soluble fertilizer formula for alleviating seedling stiffness and prompting root growth in seedling stage

Abstract

The invention discloses a water-soluble fertilizer formula for alleviating seedling stiffness and prompting root growth in a seedling stage. The NPK (nitrogen, phosphorus and potassium) content of pure potassium fulvate is 5%, and the NPK content of pure amino acid raw powder is 18%. A preparation method of the water-soluble fertilizer formula includes the following steps: after planting, mixing 80% of fulvic acid with 20% of amino acid, and irrigating the roots by a 1000-times water solution; in the second and third leaf development stages, mixing 50% of the fulvic acid with 50% of the aminoacid, and irrigating the roots by a 2000-times water solution; in the sixth to tenth leaf development stages, mixing 20% of the fulvic acid with 80% of the amino acid, and irrigating the roots by a 1000-times water solution. The water-soluble fertilizer formula has the advantages that the root growth of grape seedlings can be effectively promoted, and the germination process can be accelerated; dormancy of grape root systems can be interrupted through root irrigation, rapid rooting can be promoted, and bud eye germination and new leaf development can be promoted; the seedling growth is benefited, and the immunity in the seedling stage is improved; capillary roots can grow rapidly, and absorption can be accelerated; NPK, various amino acids and various amino acid nutrients required for theseedlings in the seedling stage are supplemented, and accordingly, the growth of the grape seedlings is accelerated.

Description

technical field [0001] The invention belongs to the technical field of water-soluble fertilizer formulas, and in particular relates to a water-soluble fertilizer formula for relieving stiff seedlings at the seedling stage and accelerating root growth. Background technique [0002] Grape seedlings are usually propagated by grafting, and good varieties are grafted on good rootstocks. Rootstocks can be propagated by sowing, cutting, branching and tissue culture. After grafting, they have wider adaptability, stronger stress resistance and stronger growth. , Higher yield, better quality, strong growth of seedlings, high survival rate, high yield, strong disease resistance, high cold resistance are the basis for the cultivation of high-quality grape seedlings. [0003] The existing grape seedlings will have some problems when they grow. The root system of the grape seedlings grows relatively slowly, and there will be a certain degree of root dormancy. Exhaustion makes it difficul...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of water-soluble fertilizer formulation that relieves the stiff seedlings at the seedling stage and accelerates the growth of the root system, so as to solve the existing grape seedlings proposed in the above-mentioned background technology when growing. There will be a certain dormancy of the root system. The climate of seedling cultivation in spring is changeable, the temperature is low, the growth of grape seedlings is slow, and the nutrients in the branches are easily exhausted, making it difficult for grape seedlings to spread leaves, not full enough, poor resistance, and easy to catch diseases , and the survival rate is low, it is difficult to treat and adjust, which not only increases the difficulty of work, but also increases the economic cost, which makes the initial investment larger, wastes time and energy, delays the normal growth of grapes and the progress of seedling cultivation, and increases the difficulty of work, etc. question
