Foliar preparation for improving crop resistance and preparation method thereof

Abstract

The invention discloses a foliar preparation for improving crop resistance and a preparation method thereof, wherein the foliar preparation comprises an amino acid fermentation waste liquid, potassiumhumate, alginic acid, a macroelement fertilizer, a medium-trace element fertilizer, a surfactant, a plant growth regulator, a pH regulator and a suspension thickening agent. The foliar preparation ofthe invention adopts the amino acid fermentation waste liquid as the main organic component to realize waste liquid utilization, so that resources are saved, and the foliar preparation is environmentally friendly and safe. In addition, the amino acid fermentation waste liquid is rich in small molecular water-soluble organic matter, can chelate trace elements, can directly provide organic nutrition to plants, and promote nutrient absorption, thereby ensuring the accumulation of carbohydrates and nutrient absorption in plants in continuous rain and haze weather, maintaining healthy growth, andeffectively preventing occurrence of wilting, yellow leaves and the like of the plants, and therefore the cold resistance and disease resistance of crops are improved, and increase of the crop yield is facilitated.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a foliar preparation for improving crop stress resistance, and also relates to a preparation method of the foliar preparation. Background technique [0002] There are two ways for crops to absorb nutrients: root absorption and foliage absorption. Crops mainly absorb nutrients in the soil or nutrient solution through roots to supply plant growth and development. In addition, they can also absorb nutrients through stems and leaves. Among them, foliar fertilization is A surface fertilization method commonly used in agricultural production to fertilize nutrient absorbers other than crop roots, that is, to supplement the nutrients needed by crops by foliar spraying to regulate crop growth. The structure of the leaf is different from that of the root. There are three ways for the leaf surface to exchange materials with the outside world: one is the stomata distributed o...

AI Technical Summary

Problems solved by technology

In addition, most foliar fertilizers also have the disadvantages of low effective content, low element utilization rate, and unstable effect.

Therefore, in recent years, domestic and foreign agricultural researchers attach great importance to the research and development, production and application of foliage fertilizer: CN 106396980 A discloses a kind of compound foliage fertilizer, which consists of surfactant, naphthalene acetic acid, compound amino acid, mineral soluble water, Indole-3-acetic acid, organic fertilizer, isopropanol, fermented fertilizer and unsaturated lime water, obviously, the compound foliage fertilizer announced by this application does not contain the trace elements needed by crops; CN 105693314 A teaches a Foliar fertilizer, which is composed of biochemical fulvic acid powder, urea, potassium dihydrogen phosphate, potassium sulfate, citric acid, methylene succinic acid and water, in terms of its composition, the foliar fertilizer also has the problem of nutritional imbalance

[0004] So far, there is no foliar fertilizer preparation, which can not only supplement various nutrients needed for crop growth, but also have balanced nutrition, and can regulate, induce and stimulate the defense ability of crops themselves, thereby improving crop drought resistance, cold resistance, Anti-waterlogging and other stress resistance to ensure the healthy growth of crops
