A special package fertilizer for apple trees with high content of nitrogen, phosphorus and potassium

Abstract

The invention provides a special set fertilizer for apple trees with high content of nitrogen, phosphorus and potassium. It rationally mixes chemical fertilizers, biological fertilizers and trace elements in a scientific proportion to form a new type of high-efficiency fertilizer, which contains comprehensive nutritional elements. , easy to decompose and absorb, high in quality, and has outstanding effects on the growth, yield, and quality of apple trees; this mixed fertilizer can be used as fruit expansion fertilizer and fruit tree base fertilizer, aiming at the nitrogen, phosphorus, and potassium content of fruit trees in different growth stages Different needs are matched to ensure the nutritional needs of fruit trees and reduce waste; it can control the content of nitrogen, phosphorus, and potassium to more than 40%, which meets the national standard for high-content compound fertilizers. The amount used reduces the residue of chemical fertilizers in the soil, protects the ecological balance of the soil, has a significant effect of long-distance fertilization, improves the pertinence of fertilizer use and the absorption rate of fertilizer components; the effect is significant, the cost is low, and the operation is simple and easy.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and specifically refers to a compound fertilizer for apple trees that has multiple functions and can be used for multiple purposes. Background technique [0002] Due to the long-term cultivation of our country's land, there have been problems such as barren cultivated land, a decrease in organic matter content in the soil, and an increase in insect pests and germs in the soil; rational use of various organic and inorganic fertilizers to improve the soil, balance land nutrition, and ensure crop production has become a must for modern agriculture. indispensable means. In different growth periods of fruit trees, it is necessary to apply different fertilizers to ensure the yield and soil quality; at present, the market is full of various fertilizers with different functions, which dazzles the fruit farmers.

Problems solved by technology

In different growth periods of fruit trees, it is necessary to apply different fertilizers to ensure the yield and soil quality; at present, the market is full of various fertilizers with different functions, which dazzles the fruit farmers. Most of these fertilizers contain single nutrients and specific functions; and Fertilizers with multiple functions have the problem of low absorption and utilization rate. Fertilizers decompose slowly in the soil and cannot be effectively absorbed and utilized by fruit trees. In addition, fruit farmers may choose different fertilizers produced by different manufacturers at different growth stages of fruit trees. Due to production Different raw material components of fertilizers will undergo physical and chemical reactions when decomposed in the soil, which hinders the absorption of nutrients and even causes an imbalance of soil nutrients.
