Fruit tree fertilizer for preventing early defoliation

Abstract

The invention discloses fruit tree fertilizer for preventing early defoliation. The fruit tree fertilizer is prepared from the following raw materials in parts by weight: 48 to 52 parts of poultry and livestock manure, 24 to 25 parts of vinegar residue, 6 to 8 parts of fresh orange peel, 0.6 to 0.8 part of soybean isoflavone, 0.5 to 0.6 part of aminotriacetic acid, 1 to 2 parts of sodium pyrophosphate, 1 to 2 parts of calcium formate, 3 to 4 parts of guar gum powder, 6 to 8 parts of chitosan, 0.2 to 0.3 part of potassium permanganate, 0.4 to 0.5 part of manganese sulfate, 1.2 to 1.5 parts of acrylic amide, 0.5 to 0.6 part of N,N'-methylene-bisacrylamide, 0.4 to 0.6 part of ammonium persulfate, 1.4 to 1.6 part of zinc acetate, 0.1 to 0.2 part of yttrium nitrate, a proper amount of an absolute ethyl alcohol solution and a proper amount of water. The fertilizer disclosed by the invention is applicable to growth of fruit trees; rich plant active components including the soybean isoflavone and the fresh orange peels and the like are added and can be effectively absorbed by roots of fruit trees under a good water solubility condition; rich-nutrient organic matters including the vinegar residues, chelating components including the calcium formate and the like are added, so that a lot of nutrient can be accumulated in tree bodies during a development period and the leaf area index is improved; a phenomenon of the early defoliation of the fruit trees is reduced under the condition that the sufficient nutrients are supplied to leaves and normal growth of the fruit trees is promoted.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a fruit tree fertilizer for preventing early defoliation. Background technique [0002] With the increasing level of modernization of agriculture, new organic fertilizers are gradually replacing ordinary chemical fertilizers and becoming important fertilizers in agricultural production. Organic fertilizers have many advantages such as complete nutrition, improved soil, and increased fertilizer utilization. However, the organic fertilizers currently available on the market have many defects. First, a large amount of greenhouse gases are likely to be generated during the preparation process, and are discharged into the atmosphere without control, causing air pollution; second, they cannot meet the needs of soil pollution restoration. Simple soil structure Improvement cannot improve the quality of crops in polluted soil; third, the supply of nutrients is slow, and although it is...
