Seaweed polysaccharide anti-transpiration paste leaf fertilizer additive specially used for pear tree

Abstract

The invention discloses a seaweed polysaccharide anti-transpiration paste leaf fertilizer additive specially used for a pear tree. The additive is prepared from the following raw materials in parts by weight: 0.8-1 part of surfactin, 6-7 parts of cytokinin, 31-34 parts of methanol, 1.2-1.3 parts of pesticide emulsifier 602, 0.3-0.31 part of anhydrous calcium chloride, 0.139-0.14 part of anhydrous magnesium chloride, a right amount of deionized water, 0.15-0.18 part of isopropanol, 3-4 parts of hydroxyethyl methyl cellulose, 3-4 parts of seaweed polysaccharide, 4-5 parts of biochemical fulvic acid, 1-2 parts of ammonium molybdate, 3-4 parts of bentonite, 0.8-1 part of sodium lauryl sulfate, 29-32 parts of urea, 15-17 parts of potassium humate, 9-11 parts of dipotassium hydrogen phosphate, a right amount of ammonium sulfate and 2-3 parts of white sugar. When the paste leaf fertilizer prepared from the additive disclosed by the invention is used for spraying pear leaves, the yield of the pear tree can be improved, and occurrence of plant diseases and insect pests can be reduced.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special seaweed polysaccharide anti-transpiration paste-like foliar fertilizer additive for pear trees. Background technique [0002] Foliar fertilizer is a type of fertilizer that applies nutrients to the surface of crop leaves and exerts its basic function through the absorption of leaves. The pores on the surface of leaves are the channels for foliar fertilizer to enter the leaves. It has fast absorption, strong effect, low dosage and high efficiency. High characteristics can supplement the deficiency of root fertilization. During the growth process of crops, crops have shown some nutrient deficiency. Since it takes a certain time for soil fertilization, nutrients can be absorbed by crops, and the deficiency of crops cannot be alleviated in time. Symptoms, at this time, foliar fertilization can make nutrients quickly enter the plant through the leaves and solve the probl...

AI Technical Summary

Problems solved by technology

In the article, the foliar fertilizer adopts a liquid formula, which has low nutrient content and is easy to crystallize out, and it is easy to lose when applied to the foliage, resulting in waste of fertilizer. Paste fertilizer is a form between solid fertilizer and liquid fertilizer. With the increase of water volume, its fluidity increases, which overcomes the shortcomings of solid fertilizers, which are easy to absorb moisture and agglomerate, dissolve slowly during use, and liquid fertilizers have low nutrient content and are easy to crystallize and precipitate.
