Ecological planting and breeding symbiosis method for fishes, shrimps and rice

Abstract

The invention discloses an ecological planting and breeding symbiosis method for fishes, shrimps and rice. The method is characterized in that the method comprises the steps that a rice field is selected and rebuilt, calcification thick liquid is used for spraying and sterilizing the field after the field is subjected to sun exposure, and annular ditches are dug along the peripheries of the innersides of ridges and used for fish and shrimp activity; elodea nuttallii and hydrilla varticillata are planted in the annular ditches, oxygen aeration equipment is arranged, an integrated water inlet and an integrated water outlet are built and formed in an opposite angle mode, wire meshes surround the water inlet and the water outlet, and fishes and shrimps are prevented from escaping; a plantingand breeding mode comprises fish stocking of young shrimps, fry putting and rice planting; fertilization comprises the steps that organic fertilizer, inorganic fertilizer and enzymes bacteria biological fertilizer are applied, fertilization is conducted on sunny days, the organic fertilizer which ferments completely is used as base fertilizer, the inorganic fertilizer is sufficiently dissolved inwater and used for spraying and top dressing, the enzymes bacteria biological fertilizer is used as efficiency promotion fertilizer, and after the enzymes bacteria biological fertilizer is immersed for half an hour, even spraying is conducted; daily management comprises the steps of water level control, regulation and control of water quality, and prevention and treatment of insect pests.

Description

technical field [0001] The invention relates to the field of fish, shrimp and rice planting and breeding symbiosis, in particular to a method for fish, shrimp and rice ecological planting and breeding symbiosis. Background technique [0002] In recent years, with the increase of international and domestic demand for crayfish, the ecological breeding area of ​​fish, shrimp and rice has continued to expand. However, for the high yield and high efficiency of fish, shrimp and rice breeding, a large amount of chemical fertilizers have been applied, resulting in soil compaction and a decline in organic matter content. , the number of soil microorganisms decreases, the water quality deteriorates, and the probability of fish and shrimp diseases and anoxic flooding increases; [0003] Most of the chemical drugs are used to prevent, control and treat fish, shrimp and rice diseases, and the drug residues are serious. [0004] endanger people's health. How to ensure high-yield, high...
