Compound fertilizer special for peanuts and preparing method of compound fertilizer

Abstract

The invention discloses compound fertilizer special for peanuts and a preparing method of the compound fertilizer. The compound fertilizer is prepared from, by weight, 3-5 parts of humic acid, 0.3-0.5 part of polyglutamic acid, 5.7-11.9 parts of inorganic matrixes, 2.1 parts of anti-blocking agents, 14-16 parts of N, 10-13 parts of P2O5, 12-15 parts of K2O, 0.5-0.9 part of Zn, 0.3-0.5 part of B and 0.2-0.4 part of Mo. By means of the compound fertilizer special for peanuts, the microelements of zinc, boron and molybdenum, active humic acid and polyglutamic acid are added while sufficient and effective nitrogen, phosphorus and potassium are ensured, major elements needed by growth of peanuts and microelements likely to lack are considered comprehensively, the added active humic acid and polyglutamic acid can improve conditions of soil, the water retaining capability of the soil is improved, mineral nutrient availability of the soil is improved, the growth and yield increase of peanuts are promoted, the microbial activity and microbial biomass of the soil are increased, and meanwhile the safety risk in organic fertilizer and formula fertilizer is avoided.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a special compound fertilizer for peanuts and a preparation method thereof. Background technique [0002] Peanut is an important oil crop and economic crop in my country. Peanut fruit is rich in protein, fat, sugar, microorganism, minerals and other nutrients, and has extremely high nutritional value, economic value, medicinal value and edible value. The fat content of peanut fruit is 44%-45%, the protein content is 24%-36%, and the sugar content is about 20%. [0003] During the growth of peanuts, it needs to absorb a variety of nutrients, including nitrogen, phosphorus, potassium and other macro elements; calcium, magnesium, sulfur and other medium elements and iron, zinc, manganese, copper, boron, molybdenum and other trace elements. Peanuts are suitable for growing in sandy soils with good air permeability, but sandy soils have relatively poor nutrient retention and soil...

Problems solved by technology

Due to the different sources of raw materials, nutrient composition and preparation methods, there are many deficiencies, such as domestic and industrial wastes may contain toxic and harmful substances, and the content of heavy metals is relatively high, and there may be harmful microorganisms exceeding the standard due to incomplete treatment during the treatment process, etc. Insufficient, simple use of compound chemical fertilizers will cause soil quality to decline
