Description
Technical Field
The invention relates to the technical field of agricultural fertilizers, in particular to a polyglutamic acid and sugar alcohol calcium aqua and a preparation method thereof.
Background
Polyglutamic acid (gamma-poly-glutamic acid, abbreviated as gamma-PGA), also known as natto gum and polyglutamic acid, is a water-soluble, biodegradable, nontoxic biopolymer prepared by using a microbial fermentation method. The polyglutamic acid is a homo-polyamino acid polymerized by glutamic acid monomers through amido bonds, has the advantages of excellent biodegradability, super-strong adsorption, no toxicity and the like, and can reduce the loss of fertilizer nutrients, improve the utilization rate of the fertilizer, regulate plant growth and the like when being added into the fertilizer. Has obvious application effect on economic crops such as fruit trees, vegetables and the like, and can obviously improve the crop yield.
The Eucarol AGE synergistic penetrant is a biological auxiliary agent and has excellent wetting and penetrating properties. Is a natural derivative, can be completely degraded and is environment-friendly. Can improve the speed of the liquid medicine permeating into the mesophyll, improve the control effect of the liquid medicine, promote the growth of crops, be used as a soil conditioner, be stable in water and be added into a water aqua to be used as a synergist.
The sugar alcohol calcium can stabilize cell membranes and cell walls, increase the hardness of fruits, enhance the toughness of fruit peels, and reduce fruit cracking, sunburn and pest damage. The yield is increased, the quality is improved, and the storage property of the fruits is improved; reducing the respiratory intensity, reducing the consumption of nutrients and delaying the aging speed of fruits; improve the resistance of crops, and improve the antifungal capability.
The crops lack calcium elements, the tip parts of the leaves are bent and yellow-whitened, the leaf edges are folded upwards or downwards, the veins of the young leaves are yellowed, the fruit peels are rotted and split, the roots supplement calcium, the calcium is easily fixed in the soil and is also easily precipitated in the crops, the utilization rate is not high, and therefore, the calcium is needed to be supplemented outside the roots. Sugar alcohol calcium is a novel fertilizer product created by supplementing calcium outside roots, and has the advantages that a pure natural sugar alcohol chelating agent is adopted, calcium ions can be carried to quickly permeate into leaves or fruit peels after spraying, and can be directly and quickly transported to fruit parts needing calcium through xylem and phloem, so that the problem of supplementing calcium outside the roots of crops is well solved. The preparation of the novel product by compounding is an important means for realizing sustainable, green and healthy development of agriculture.
At present, the compounding of polyglutamic acid and sugar alcohol calcium is not reported.
