preparation Embodiment 1

[0045] 30 kg of amino acid fermentation waste liquid (wherein the solid content is 9 kg, and the water-soluble organic matter content is 4.5 kg) is heated to 75 degrees Celsius, and then the pH of the amino acid fermentation waste liquid is adjusted to 6.0 with a mass fraction of 20% sodium hydroxide aqueous solution. Thereafter, 0.5 kg of zinc sulfate, 0.5 kg of ferrous sulfate, 0.5 kg of copper sulfate, 2 kg of borax, and 1 kg of magnesium sulfate were added and stirred for 1.5 hours. Thereafter, 5 kg of urea, 5 kg of ammonium polyphosphate, 10 kg of potassium dihydrogen phosphate, 0.1 kg of alginic acid, 5 kg of potassium humate and 0.2 kg of hydroxypropyl methylcellulose were added to the reaction system, and 0.01 kg of sodium nitrophenolate and surface Active agent Tween-20 0.05kg, then stirred for 2 hours to obtain the foliar preparation of the present invention.

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...
