Abstract

The invention discloses a water-soluble fertilizer for preventing defoliation of pear trees in early stage. The fertilizer comprises the following raw materials in parts by weight: 40-60 parts of urea, 5-15 parts of potassium dihydrogen phosphate, 5-12 parts of sylvinite, 15-25 parts of plant ash, 2-10 parts of ammonium nitrate, 2-8 parts of a calcium magnesium phosphate fertilizer, 1-2 parts of boric acid, 0.2-0.8 part of salicylic acid, 0.2-0.6 parts of amino chitosan oligosaccharide, 0.3-0.7 part of calcium amino acid, 0.1-0.4 part of diethyl aminoethyl hexanoate, 0.3-0.8 part of phytoalexin, 0.08-0.14 part of zinc fulvic acid, 0.5-0.9 part of ammonium chloride, 0.1-0.4 part of copper fulvic acid, 1-3 parts of peat, 1-2 parts of clay, 1-3 parts of modified microcrystalline cellulose, 1-3 parts of cyclodextrin, and 1-3 parts of an auxiliary material. The fertilizer can improve stress resistance of pear trees, increases sweet taste of pears, prevent defoliation of pear trees in early stage, satisfy needs of growth and development of pear trees with scientific nutrition proportion, promote growth of pear trees, and improve quality.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a water-soluble fertilizer for preventing early leaf fall of 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 qual...
