Preparation method of organic biological fertilizer favorable for increasing yield

Abstract

The invention discloses a preparation method of an organic biological fertilizer favorable for increasing yield, and belongs to the technical field of agriculture. The preparation method comprises the following steps: mixing straws, poultry manure, bentonite, charcoal ash and humic acid with the specified formula quantity; fermenting the materials, which are mixed uniformly, for about 8 to 12 days, wherein the temperature is maintained to be between 25 and 30 DEG C during the previous 5 to 6 days and the fermentation temperature is maintained to be between 35 and 40 DEG C during the last 3 to 6 days; drying the materials in the open air for 2 days and performing fermentation for the second time, wherein the fermentation time is 3 to 4 days, the fermentation temperature is 40 to 45 DEG C and turning and throwing are conducted in the fermentation period; and spreading and drying the fermented materials in the sun by controlling the temperature to be between 22 and 35 DEG C. The preparation method has the advantages that the steps are designed scientifically and reasonably; the defects in the prior art are avoided; the utilization ratio of inorganic fertilizer can be increased; the absorption effect is good; the yield can be increased under the condition of the same use amount of the fertilizer; furthermore, a fertilization method is simple, multi-time fertilization is avoided, the cost is reduced and the economic value is high.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a preparation method of an organic biological fertilizer which is beneficial to improving yield. Background technique [0002] Agriculture is an industry that uses the growth and development laws of animals and plants to obtain products through artificial cultivation. Agriculture belongs to the primary industry, and the science that studies agriculture is agronomy. The objects of labor in agriculture are living animals and plants, and the products obtained are the animals and plants themselves. Agriculture provides basic products that support the construction and development of the national economy. [0003] Agriculture refers to an important industrial sector in the national economy. It is a sector that takes land resources as its production object. It is an industry that produces food and industrial raw materials by cultivating animal and plant products. Agriculture be...

Problems solved by technology

[0007] Many fertilizers are in the form of powder, and need to be mixed with water when fertilizing, and general organic fertilizers only give relevant nutrients to crops, but the absorption of nutrients is average, so a growth cycle requires several fertilization, high labor costs, and The cost of fertilizer is also high
