Biological compound fertilizer

Abstract

The invention discloses a biological compound fertilizer which is prepared from the following raw materials in parts by weight: 45-55 parts of milk cow manure, 50-70 parts of rotten chicken manure, 2-4 parts of wood vinegar, 5-15 parts of microbial inoculant, 100-120 parts of straw particle, 15-25 parts of coal slag, 10-20 parts of sodium borate, 1-3 parts of microbial fermentation agent, 40-50 parts of tofu pulp, 20-30 parts of Bacillus subtilis culture, 10-20 parts of glucose, 5-15 parts of bryophyte, 20-30 parts of amino acid, 10-20 parts of potassium sulfate, 15-25 parts of tobacco waste, 40-50 parts of monoammonium phosphate, 20-40 parts of tea slag and 8-12 parts of soil conditioner. The biological compound fertilizer can promote quick growth of crops, reduce diseases and improve the problems of soil hardening and the like.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a biological compound fertilizer. Background technique [0002] With the gradual increase in the utilization rate of domestic fertilizers, the requirements for fertilizers are also constantly increasing. At present, a large amount of chemical fertilizers are used, which seriously leads to the increase of harmful substances in crops, and the microbial flora has been damaged to varying degrees, resulting in poor quality. Insufficient nutrition, especially the soil is easy to compact, the drought resistance effect is poor, and the water retention performance becomes poor, which seriously affects the normal growth of crops, thereby affecting the poor economic benefits of agriculture. [0003] Biological fertilizer is an effective way to change the disadvantages of existing chemical fertilizers. The invention provides a biological compound fertilizer, which can improve the abso...
