Abstract

The invention belongs to the technical field of fertilizer, in particular to compound biofertilizer and a preparation method thereof. The compound biofertilizer is prepared by taking apple pomace, crap straw, poultry feather, and urea as fermentation primers, cane sugar and carboxymethylcellulose as encapsulating agents, streptomyces microflavus, paecilomyces lilacinus, bacillus subtilis and bacillus licheniformis as zymophyte, and fermenting; according to the compound biofertilizer provided by the invention, through synergistic interaction of various microbial strains, the requirement on soil is greatly reduced, the physical property of soil and quality of crops are improved, the disease-resistant and continuous cropping resistant capacities are improved, the cane sugar and the carboxymethylcellulose are taken as the encapsulating agents, the nutrient needing by microbial action in later period is provided, meanwhile, the water and nutrient retention capacity of the soil is improved, and the crop yield can be improved by about 30 percent.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a compound microbial fertilizer and a preparation method thereof. Background technique [0002] With the sharp reduction of arable land, the contradiction between the ever-increasing food demand of the growing population has become increasingly acute. In recent decades, in order to meet the needs of food production in my country, the input of agricultural chemicals has reached a very high proportion. This unsustainable agricultural production mode not only seriously pollutes our limited land and water resources, but also causes food safety incidents. It is also closely related to this mode of agricultural production. Microbial fertilizer is a kind of product in which the life activities of microorganisms cause crops to obtain specific fertilizer effects. It can not only improve the utilization rate of fertilizers, but also improve soil physical properties, improve...
