Method for cultivating penaeus vannamei in rice field

Abstract

The invention relates to the technical field of aquatic product culture, and particularly relates to a method for culturing penaeus vannamei in a rice field. The method of the invention including thefollowing steps of: treating the rice field by using horseradish and hydrogen peroxide; planting water grass in the deep part of the rice field, inoculating oocystis borgei, nannochloris oculata and chlorella pyrenoidosa, and dispersively planting radix arnebiae and potamogeton crispus in the rice field; changing water at regular time, and adding decomposed farmyard manure with composite microbialagent prepared by compounding bifidus, pichia pastoris, enterococcus faecium, bacillus licheniformis and bacillus natto; applying a mixed Chinese herbal medicine supplement prepared by crushing horseradish, herba artemisiae scopariae, herba leonuri, flos lonicerae, rhizoma belamcandae, and herba artemisiae scopariae periodically to water. According to the method, farmyard manure, probiotics and Chinese herbal medicines are used, natural plants are planted, the whole process is green and harmless, the quality of shrimp meat is kept at a higher level, the comprehensive economic benefits of whole culture are kept at a higher level, and the economic benefits are greatly improved.

Description

technical field [0001] The invention relates to the technical field of aquatic product cultivation, in particular to a method for cultivating Penaeus vannamei in paddy fields. Background technique [0002] The adult Penaeus vannamei can be up to 24cm long, with a thin carapace. The normal body color is light blue-gray, and there are no markings on the whole body. The legs are often chalky, so they are called white-legged shrimps. Penaeus vannamei has thin shell and fat body, delicious meat, high meat content and rich nutrition. Penaeus vannamei has strong adaptability. The natural habitat is the muddy seabed with a water depth of 0-72m. It can grow in waters with a salinity of 0.5-35‰. For juvenile shrimp of 2-7cm, the allowable range of salinity is 2-78‰. It can survive in waters with a water temperature of 6-40°C, the growth water temperature is 15-38°C, and the optimum growth water temperature is 22-35°C. The high temperature tolerance limit is 43.5°C (gradual range), ...

Problems solved by technology

Most methods of cultivating Penaeus vannamei in rice fields still need to use a large amount of disease-resistant and insect-resistant drugs in the process of rice planting and Penaeus vannamei culture. Rice pesticides will affect Penaeus vannamei, resulting in mortality and disease of Penaeus vannamei rate rises and yields decrease. In the cultivation process of Penaeus vannamei, it is necessary to use drugs for disease resistance and killing enemies. The overlapping use of drugs with rice will lead to the enrichment of harmful components in Penaeus vannamei, resulting in a decline in the quality of the shrimp. Very prone to hypoxia, resulting in illness or even death of Penaeus vannamei

[0006] Therefore, at present, traditional Chinese medicine or microorganisms are used for pond cleaning and prawn cultivation. For example, "CN201711435274-Chinese medicinal liquid" provides a technical solution for adding Chinese medicinal liquid to feed, and "CN201410157171 Whole Pond-Disinfection-Bacteria" , "CN201510041962-Bacteria + Water Purification", but currently there is no treatment method for Penaeus vannamei, and other treatment methods are less effective when used for Penaeus vannamei
