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...

[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 environment because of its omnivorous nature, fast growth speed, and strong adaptability; its food range includes aquatic plants, algae, aquatic insects, animal carcasses, etc. Shrimp farming in paddy fields is a A new model of crayfish farming, to achieve the greatest economic benefits by planting rice in rice paddies and raising shrimp in furrows; however, there are still certain risks in raising shrimp in paddy fields, and poor management will lead to reduced production or even death of crayfish, which brings great challenges to farmers; Scientific and reasonable farming is the key to successful farming;

[0003] Crayfish have strong viability and can survive in harsh environments, but this does not mean that crayfish like such a living environment. People often have this kind of cognitive misunderstanding, so rectifying the living environment of crayfish is important for the growth and reproduction of crayfish These are all crucial points; under the condition of the existing rice-shrimp polyculture field management technology, the following problems still exist in the rice-shrimp polyculture field: First, the rotten rice straw will affect the geological environment and cause geological deterioration; The effect of the existing compound bacterial agents on the market is single, and the effect is not ideal; with the long-term polyculture of rice and shrimp, the effect will become smaller and smaller; resulting in repeated deterioration of the water body, resulting in various harmful aquatic products Biological toxins increase the number of harmful bacteria in the water and reduce the beneficial bacteria, making the microbial composition unbalanced, which is not conducive to the growth of rice and shrimp
