Special meal fertilizer with proper amount of nitrogen, phosphorus and potassium for apple trees

Abstract

The invention provides a special meal fertilizer with a proper amount of nitrogen, phosphorus and potassium for apple trees. The novel multifunctional, multipurpose and efficient fertilizer is prepared by reasonably and scientifically compounding a chemical fertilizer, a biological fertilizer leaven and microelements in proportion, and contains comprehensive nutrient elements, is easy to decompose and absorb as well as good in quality and especially has obvious effects on the growth, the yield and the quality of the apple trees. The mixed fertilizer can serve as a fruit hormone fertilizer, an apple tree base fertilizer and an apple tree germination fertilizer, and is proportioned aiming at different requirements of the apple trees at different growth phases to the nitrogen, the phosphorus and the potassium so as to guarantee the nutritional requirements of the apple trees and reduce waste. According to the fertilizer, the content of the nitrogen, the phosphorus and the potassium can be controlled within 30% to 40%, so that the national standard of the compound fertilizer with a proper amount of nitrogen, phosphorus and potassium is met, the fertilizer concentration is effectively reduced, and the phenomenon of seedling burning caused by the close-range application of the fertilizer is avoided. The fertilizer is applied once in one year, so that the application pertinence of the fertilizer and the absorptivity of fertilizer components are improved. The fertilizer provided by the invention is obvious in effect, low in cost, simple to operate and easy to apply.

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.
