Special nutrition-balanced water-soluble fertilizer for pear tree

Abstract

The invention discloses a special nutrition-balanced water-soluble fertilizer for a pear tree. The special nutrition-balanced water-soluble fertilizer for the pear tree comprises the following raw materials in parts by weight: 30-50 parts of urea, 10-16 parts of sodium nitrate, 5-15 parts of calcium superphosphate, 2-8 parts of potassium sulfate, 2-6 parts of potassium chloride, 25-35 parts of a kiln ash potassium fertilizer, 0.1-0.2 part of zinc fulvate, 0.05-0.12 part of ferric fulvate, 0.4-0.8 part of manganese sulfate, 0.15-0.25 part of calcium amino acid, 1-3 parts of boron mud, 0.5-1.5 parts of salicylic acid, 0.2-0.8 part of diethyl aminoethyl hexanoate, 0.1-0.8 part of amino chitooligosaccharide, 0.15-0.25 part of phytoalexin, 1-5 parts of modified sodium carboxymethyl cellulose, 2-6 parts of lignin, 2-6 parts of activated carbon, 1-3 parts of zeolite powder and 1.2-1.4 parts of an auxiliary material. The special nutrition-balanced water-soluble fertilizer for the pear tree can improve the stress resistance of the pear tree, improve the sweetness of pears and prevent early leaf falling, is scientific in nutrient ratio, and can promote pear growth and improve the pear quality.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a nutritionally balanced water-soluble fertilizer special for pear trees. Background technique [0002] Pear is one of the main fruits with long cultivation history, high yield and wide planting area in my country. Because pears are crisp, sweet and juicy, they are suitable for the taste of our people, so pears have always been popular among people. At the same time, pear is also the most exported fruit in my country, with high economic value, so the planting area is increasing year by year. Early defoliation is one of the major problems that plague the development of the pear tree industry. Every year, early defoliation causes tree body weakness, yield reduction, quality decline, and frequent occurrence of diseases, seriously affecting orchard production and economic benefits. In recent years, with the improvement of people's living standards, the requirements for pear qua...
