Rice and shrimp ecological co-cultivation method with stable water quality and low diseases and insect pests

Abstract

The invention provides a rice and shrimp ecological co-cultivation method with stable water quality and low diseases and insect pests. The method comprises the following steps: (1) paddy field selection and transformation are performed; (2) rice cultivation is performed; (3) young shrimp throwing-in and feeding management are performed: snails, mussels and clams are thrown into a circular shrimp ditch; a compound microbial agent is applied; and juvenile shrimps are thrown in after seedlings turn green; and (4) at the juvenile shrimp stage, a water depth of the paddy field is 50-60 cm; at the adult shrimp stage, a water depth of the paddy field is 65-70 cm; an EM bacterial agent A is applied to the annular shrimp ditch when the weather is 32-33 DEG C high-temperature weather for 5 consecutive days or more; and an EM bacterial agent B is applied to the annular shrimp ditch when the weather is rainy weather for 5 consecutive days or more. The method can more reasonably control the water quality and water level of co-cultivation, effectively reduces diseases and insect pests, improves the growth quality of rice and shrimps, and realizes rice and shrimp ecological co-cultivation with high and stable yield.

Description

technical field [0001] The invention relates to the technical field of rice cultivation, in particular to an ecological co-cultivation method for rice and shrimp with stable water quality and low pest damage. Background technique [0002] Co-cultivation of rice and shrimp is an ecological breeding technology that integrates planting and breeding under the effect of biological symbiosis and mutual benefit to realize planting and breeding. With the continuous research and promotion of the rice-shrimp co-cultivation model, it has developed rapidly. However, the existing co-cultivation methods have not been able to form a unified standardized technology. Under the co-cultivation mode of rice and shrimp, the requirements for water quality are usually very high, and it is often easy to produce diseases and insect pests due to improper control of water quality and water level in the process of planting and breeding. It affects the low growth quality of rice and the low survival ra...

However, the existing co-cultivation methods have not been able to form a unified standardized technology. Under the co-cultivation mode of rice and shrimp, the requirements for water quality are usually very high, and it is often easy to produce diseases and insect pests due to improper control of water quality and water level in the process of planting and breeding. It affects the low growth quality of rice and the low survival rate of shrimp, which limits the stable and high yield of rice and shrimp co-culture
