A fertilizer prepared from wormcast and a preparation method of the fertilizer

Abstract

The invention discloses a fertilizer prepared from wormcast and a preparation method of the fertilizer. The fertilizer is prepared from following raw materials in parts by weight: 30-40 of wheat straw, 25-30 of rice straw, 20-25 of cotton seed hull, 10-15 of sawdust, 20-25 of the wormcast, 12-14 of urea, 5-7 of acrylic acid, 9-11 of ammonium biphosphate, 3-5 of potassium persulphate, 2-3 of sodium selenite, 2-4 of potassium silicate, 1-3 of ammonium molybdate and 12-14 of a soil modifier. The fertilizer prepared from the wormcast adopts the wormcast, the straw, the cotton seed hull, the sawdust, and other raw materials. The raw materials are convenient to take and low in cost. The urea, the ammonium biphosphate, the acrylic acid, and other chemical raw materials are added for supplementation, thus fully utilizing resources, reducing the production investment, and reducing pollution caused by the chemical fertilizers. In addition, the wormcast has good porous property, air permeability, water permeability and high water-holding capacity. The soil does not harden after the wormcast is mixed with the soil. The wormcast is large in surface area, and therefore a lot of beneficial microorganisms can survive and the wormcast has capability of absorbing and maintaining nutrients. The wormcast is rich in bacteria, actinomyces and funguses. The microorganisms can not only mineralize complex compounds into easily-absorbed effective compounds, but also synthesize a series of compounds with biological activity, such as sugar, amino acids, vitamins, and the like.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a fertilizer made from vermicompost and a preparation method thereof. Background technique [0002] my country is a big agricultural country, and it is also a big country that uses fertilizers. According to the statistics of my country's Ministry of Agriculture, the annual use of chemical fertilizers in my country accounts for 35% of the world's total. However, the utilization rate of fertilizer in our country is much lower than that in developed countries, and a large amount of fertilizer remains on the ground, which not only causes a serious decline in soil quality, but also pollutes water bodies, posing a threat to the sustainable development of my country's agriculture and the living environment of human beings. Therefore, it is imperative to develop new types of fertilizers and optimize the structure of fertilizers. The fertilizer made from vermicompost of the present ...
