Organic biological composite fertilizer and preparation method thereof

Abstract

The invention relates to an organic biological composite fertilizer and a preparation method thereof. The composite fertilizer contains ammonium phosphate, K2O (KCl, K2SO4 or K2CO3), peat and a microbial fertilizer. The composite fertilizer has the advantages of large content of humic acid, change of the physical and chemical performances of soil, changing of the soil hardening state of land, increase of the soil fertility, good stress resistance and good yield increasing effect.

Description

technical field [0001] The present invention relates to fertilizer, especially a kind of compound fertilizer. . Background technique [0002] A large amount of inorganic fertilizers are applied to the land, and the amount per mu increases from a few catties to tens of catties, so that the humus in the soil is gradually reduced, and various effective ingredients are out of balance. Coupled with the predatory planting method, it temporarily increases (or maintains the current level). ) crop yield, however, these all increase the potential harm, such as the destruction of soil structure, land compaction, imbalance of water, fertilizer, gas and heat inside the soil, physical and chemical properties that cannot meet the needs of crops, etc. Long-term and continuous use of single-effect and negative-effect inorganic fertilizers will reduce humic acid in the soil, which will not only cause land compaction and damage the soil structure, but also cause nitrogen, phosphorus, potassiu...
