Method for preparing special compound biological medicine fertilizer for apple trees, and special compound biological medicine fertilizer for apple trees prepared by same

Abstract

The invention provides a method for preparing a special compound biological medicine fertilizer for apple trees, which comprises the following raw materials in parts by weight: 30-40 parts of kitchen wastes, 20-30 parts of tobacco straws, 10-15 parts of plant ash, 10-15 parts of distillers' grains, 16-18 parts of potassium humate, 10-12 parts of bird feathers, 18-22 parts of modified fly ash, 12-14 parts of urea, 11-13 parts of ammonia water, 14-16 parts of diammonium phosphate, 13-15 parts of potassium sulfate, 11-13 parts of calcium superphosphate, 2-4 parts of cnidium fruit, 2-4 parts of aloe, 3-5 parts of eucalyptus leaves, 2-4 parts of pharbitis seed, 3-5 parts of cyrtomium rhizome, 0.5-0.8 part of zinc sulfate, 0.8-1.0 part of magnesium sulfate, 0.7-0.9 part of boric acid, 0.4-0.6 part of fermentation preparation and a proper amount of citronella oil. After various organic wastes are mixed and fermented to produce green organic fertilizers, the environmental pollution is reduced, the fermented organic matter is mixed with the inorganic fertilizer, the Chinese herbal medicine juice (citronella oil) with insecticide properties is added, the nutrition is more comprehensive, and the bactericidal effect is increased; the fertilizer has the advantages of obviously improved fertilizer utilization ratio, single time of application, effective slow release, reduced fertilization frequency, reduced fertilizer cost and improved economic benefit; and after the application of the fertilizer, the quality of the apple trees can be effectively improved, and the yield can be improved.

Description

technical field [0001] The invention relates to medicinal fertilizers, in particular to an organic-inorganic compound biological medicinal fertilizer special for apple trees and a preparation method thereof. Background technique [0002] Agricultural production requires soil to provide nutrients for crop growth and a living environment. The application of chemical fertilizers has played a key role in increasing agricultural incomes for many years. However, due to the long-term application of chemical fertilizers, insufficient supply of organic fertilizers, and imbalances in the proportion of various nutrients, the ecological environment of farmland, soil physical and chemical properties, and soil biota have been damaged to varying degrees, and the quality of agricultural products has been affected to a certain extent. Therefore, chemical fertilizer pollution has become a major public hazard in the world today. The current status of soil resources in my country urgently ne...

Problems solved by technology

[0005] my country is a large agricultural production country. With the high utilization of fertilizers, the requirements for fertilizers are constantly increasing. At present, a large amount of inorganic fertilizers are used, which seriously leads to the increase of harmful substances in crops, poor quality, and incomplete nutrition. Secondly, the soil is easy to Hardening, poor drought resistance, and poor water retention performance, which seriously affects the normal growth of crops and poor economic benefits
