Rice-shrimp polyculture field microbial complex inoculant

Abstract

A rice-shrimp polyculture field microbial complex inoculant is prepared from four stains including photosynthetic bacterium, bacillus subtilis, zinc sulfate, bacillus licheniformis and sugarbeet saccharose serving as an additive; in parts by mass, 18 parts of photosynthetic bacterium, 12 parts of bacillus subtilis, 20 parts of sugarbeet saccharose, 2 parts of zinc sulfate and 5 parts of bacillus licheniformis are mixed to prepare a mixed agent; the microbial complex inoculant further comprises 43 parts, by mass, of pure water; the pure water serves as a diluent to be mixed with the mixed agentto prepare the complex inoculant; the effective number of living bacteria of the photosynthetic bacterium, the bacillus subtilis and the bacillus licheniformis in the complex inoculant is higher thanor equal to 0.2 billion/liter; the applied photosynthetic bacteria can be rhodopseudomonas palustris; the applied bacillus licheniformis can be bacillus latersprorus and paenibacillus polymyxa; and the photosynthetic bacteria can be rhodospirillum rubrum and purple nonsulfur bacteria.

Description

technical field [0001] The invention belongs to the technical field of bacterial agents for treating rice and shrimp fields, and in particular relates to a microbial composite bacterial agent for rice and shrimp mixed cultivation fields. Background technique [0002] Crayfish, also known as Procambarus clarkii, red crayfish and freshwater crayfish; shaped like a shrimp but with a hard shell, the adult body is about 5.6-11.9 cm long, dark red, the carapace part is nearly black, and there is a wedge-shaped stripe on the back of the abdomen; the juvenile shrimp is Uniform gray, sometimes with black ripples; claws are long and narrow, the middle of the carapace is not separated by mesh-like gaps, and there are obvious particles on the carapace; the forehead has side spines or the end of the forehead has nicks; it is a freshwater economic shrimp, because of the meat taste Delicacy is widely welcomed by people; it forms an absolute competitive advantage in the local ecological env...
