Special organic-inorganic compound fertilizer for apples

Abstract

The invention relates to a special organic-inorganic compound fertilizer for apples. The organic-inorganic compound fertilizer comprises the following raw materials in parts by weight: 180-220 parts of sugar residue, 20-50 parts of fulvic acid, 20-30 parts of an amino acid-trace element chelate, 20-30 parts of a binder, 180-220 parts of urea, 220-250 parts of monoammonium phosphate, 230-250 parts of potassium sulfate and 40-60 parts of ammonium sulfate; on the basis of the raw materials, 20-30 parts by weight of a nutritional regulator can be simultaneously added, the nutritional regulator comprises the following components in percentage by mass: 20-30% of chitosan oligosaccharide, 15-18% of ammonium molybdate, 20-35% of calcium propionate, 5-8% of ascorbic acid, 8-10% of amino acid and 18-25% of ZnCl2. The organic-inorganic compound fertilizer disclosed by the invention has the advantages that the soil is improved, the nutrient is evenly released, the diseases of apple trees are prevented, the resistance of plants is enhanced, the weight of single fruit is significantly increased, the color of the fruit is good, the yield is high and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and relates to an organic-inorganic compound fertilizer, in particular to an organic-inorganic compound fertilizer special for apples. Background technique [0002] Apple is one of the most popular and popular fruits in China. It is an important fruit tree species in my country. It has a long growth cycle and requires a large amount of fertilizer. Due to the excessive use of chemical fertilizers and crops planted year after year, soil fertility is reduced and pests and diseases are becoming more and more serious. , resulting in poor disease resistance of fruit trees, weak tree bodies, no sticks, few fruits, and even fruit tree flesh quality deterioration, discoloration, softening, and rot. Most of the apple fertilizers used now are empirical formulas, and most of them focus on nitrogen fertilizer application. Neglecting the principle of balanced fertilization, unreasonable ...

[0002] Apple is one of the most popular and popular fruits in China. It is an important fruit tree species in my country. It has a long growth cycle and requires a large amount of fertilizer. Due to the excessive use of chemical fertilizers and crops planted year after year, soil fertility is reduced and pests and diseases are becoming more and more serious. , resulting in poor disease resistance of fruit trees, weak tree bodies, no sticks, few fruits, and even fruit tree flesh quality deterioration, discoloration, softening, and rot. Most of the apple fertilizers used now are empirical formulas, and most of them focus on nitrogen fertilizer application. Neglecting the principle of balanced fertilization, unreasonable fertilizer application and lack of special fertilizers for apple growth, resulting in a reduction in apple production, resulting in serious fertilizer waste and environmental pollution problems

[0003] The application of compound fertilizers to fruit trees can overcome the problem of soil nutrient imbalance caused by the application of simple chemical fertilizers, but the effective utilization rate of existing compound fertilizers is low, the loss is fast, and the amount of waste is large, which cannot completely solve soil compaction and atmospheric soil pollution of groundwater sources. question

At the same time, it has few nutrients and cannot comprehensively supply the nutrients needed for the growth and development of fruit trees to promote fruit growth, so the growth potential is limited.
