Abstract

The invention relates to the field of production of chemical fertilizer, in particular to slow-release fertilizer for garden green plants as well as a preparation method thereof. The slow-release fertilizer comprises the following components: garden plant waste, rice bran, a microbial agent, chitin, animal excrement, marine spirillum powder, rotenone, pomace, biogas residues, amino acid, carboxymethylcellulose, ethanol, silicone oil emulsion, potassium persulfate, aziridine, an emulsifier and a proper amount of water. The fertilizer prepared by the method has high persistence, and can effectively reduce loss of fertilizer, increase the utilization rate of the fertilizer, reduce the fertilization times and reduce the labor intensity of farmers and environment burden; meanwhile, the raw materials are selected from environment-friendly waste materials and residues, so that various nutritional elements can be provided for crops; in addition, by the spray-coating method, coated liquid can directly reach to the surface of the fertilizer maximally and is solidified to form a film, so that the distribution uniformity of the film material on the fertilizer granules is greatly improved.

Description

technical field [0001] The invention relates to the field of chemical fertilizer production, in particular to a slow-release fertilizer for garden plants and a preparation method thereof. Background technique [0002] my country's chemical fertilizer industry has developed rapidly since 1949. The development sequence is first nitrogen fertilizer, then phosphorus fertilizer, then potassium fertilizer, and compound (mixed) fertilizer. Composite direction is moving forward. At present, the pattern of my country's chemical fertilizers is: nitrogen fertilizer is basically self-sufficient, a small amount of phosphorus fertilizer is imported, and most of potash fertilizer needs to be imported. Chemical fertilizers have always been an important factor in increasing crop production, contributing as much as 40% to the increase in my country's grain production. However, the unreasonable use of chemical fertilizers has brought a series of problems to the quality of cultivated land for ...
