Problems solved by technology

[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.

Embodiment

[0024] A method for ecological planting and breeding of fish, shrimp and rice is characterized in that, it is carried out according to the following steps:

[0025] (1) Selection and transformation of paddy fields, excavation of ring ditches, and planting of aquatic plants:

[0026] Choose a paddy field with a flat bottom, with sufficient water sources and good water quality nearby. After exposure to the sun, use 70kg of quickliming slurry per mu for disinfection; excavate a circular ditch along the inner side of the field ridge for fish and shrimp activities. The area of ​​the circular ditch accounts for 7% of the total area of ​​the paddy field. The ditch is 1.5m wide and 0.6m deep, and an appropriate amount of Elodea and Hydrilla verticillium are planted in the ring ditch, equipped with aeration equipment;

[0027] The soil from digging the ring ditch is used to widen and heighten the field ridges, and to build a complete inlet and outlet. The water inlet and outlet are arr...

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...
