Description
Technical Field
The invention relates to the field of agriculture, in particular to a preparation method of a wormcast fertilizer.
Background
The wormcast is a good decomposed organic fertilizer and is also soil with a granular structure, so that the wormcast has a good promoting effect on the growth and development of crops. The earthworm feces is rich in bacteria, actinomycetes and fungi, the microorganisms not only mineralize complex substances into effective substances which are easy to be absorbed by plants, but also synthesize a series of substances with biological activity, such as sugar, amino acid, vitamins and the like, and the production of the substances enables the earthworm feces to have a plurality of special properties. After the earthworm feed is ground by the sand bag in the earthworm body, the surface area of the earthworm feed is greatly increased, so that the earthworm feed is convenient for the microorganism to quickly transform the earthworm feed, and in the whole digestion process, the microorganism and the earthworm are interdependent and mutually promoted, so that the earthworm feed is not only beneficial to the absorption of nutrition, but also beneficial to the quick increase of beneficial microorganisms. Under the condition that no exogenous beneficial microorganism is added in the earthworm cast during the decomposition, no relevant report is provided in the existing method on how to improve the beneficial microorganism in the decomposed fertilizer.
Disclosure of Invention
The invention aims to solve the problem that beneficial microorganisms cannot be effectively improved under the condition that no exogenous beneficial microorganisms are added in the preparation of wormcast fertilizer, and provides a preparation method of wormcast fertilizer.
The preparation method of the wormcast fertilizer provided by the invention comprises the following steps of:
firstly, cutting off crop straws according to the ratio of 5-20 g/m2Adding a straw decomposition agent, adding earthworms according to the amount of 15-30 earthworms added to each gram of crop straw, adding biomass charcoal according to the amount of 10-50 g/kg, uniformly mixing, and composting for 30-60 d; during the period, turning over the pile; wherein, the water content of the crop straws is controlled to be 40-80% in the composting and decomposing process, and the temperature of the compost is 18-28 ℃; the biomass charcoal is one or two of rice hull charcoal and corncob charcoal;
secondly, mixing the composted and decomposed crop straws with wormcast according to the mass ratio of 1: 1.2-2 to obtain the wormcast fertilizer.
The invention has the following beneficial effects:
according to the invention, the biomass charcoal is added in the straw fermentation, and the surface porous structure of the biomass charcoal is utilized to provide more attachments for nutrients and microorganisms, so that the establishment of microbial population is facilitated. In addition, when the earthworms are fed, the biomass charcoal enters the intestinal tracts of the earthworms and can indirectly influence the microorganisms by influencing the properties of the intestinal microorganisms and the matrix, and the rapid growth of a large amount of beneficial microorganisms in the intestinal tracts of the earthworms is utilized. Moreover, the hydrophobic adsorption of the biomass charcoal, the pi-pi electron donor-acceptor action and the like weaken the transfer capacity of antibiotics, and the added earthworms can generate various beneficial microorganisms and can remove part of the antibiotics after being treated by earthworm intestinal tracts. After the biomass charcoal is treated by the earthworm intestinal tract, the biomass charcoal is mixed with earthworm feces to form earthworm biomass charcoal feces, so that the adsorption effect of the earthworm feces fertilizer can be obviously improved.
