Method for culturing penaeus vanmamei in paddy fields

Abstract

The invention relates to a culture method, in particular to a method for culturing penaeus vanmamei in paddy fields. The method is characterized in that organic fertilizers are applied into the paddy fields, so that the content of organic matters in soil can reach approximately 29.2 g / kg<-1>(+ / -0.46), ditches are excavated in the paddy fields, the paddy fields can be in the shapes of double-square combinations, four-square combinations and single squares, and the areas of penaeus vanmamei ditches account for approximately 30% of the total paddy rice areas; water is a foundation for growth of plants at late stages and growth of paddy rice in the paddy fields, accordingly, the safety of the water quality needs to be guaranteed, water harm removal is carried out on all water areas of lands surrounding the paddy fields before rice seedlings are transplanted, and survival environments are guaranteed for the paddy rice; the rice seedlings are transplanted in due time according to development of the seedlings and are transplanted by the aid of rice seedling transplanting machines; the penaeus vanmamei is desalted, the desalted penaeus vanmamei is cultured in fresh water for a period of time, and the penaeus vanmamei is released into the paddy fields after the rice seedlings are transplanted by approximately a week; the penaeus vanmamei can be harvested after being raised for 100 days; the fields are sunned, and the paddy rice can be harvested.

Description

technical field [0001] The invention relates to a breeding method, in particular to a mixed three-dimensional raising method. Background technique [0002] In the prior art, there are more and more farmers who carry out three-dimensional farming in rice fields, such as raising loach, snakehead, lobster, freshwater shrimp, and crabs. However, no matter which of the above-mentioned farming methods The method, the reduction of rice field production is certain, some farmers in order to increase the production of fish and shrimp, the grain is almost no grain harvest, it has been proved by experiments that for three-dimensional farming, especially in rice fields, many households are not for 1+1> 2. The main reason is that the income of growing rice alone is too low. In addition, it is also because the cost of aquaculture alone is too high. The key is that there is no government subsidy. After the three-dimensional farming, many farmers dig ditches in the farmland Stocking aqua...

[0002] In the prior art, there are more and more farmers who carry out three-dimensional farming in rice fields, such as raising loach, snakehead, lobster, freshwater shrimp, and crabs. However, no matter which of the above-mentioned farming methods The method, the reduction of rice field production is certain, some farmers in order to increase the production of fish and shrimp, the grain is almost no grain harvest, it has been proved by experiments that for three-dimensional farming, especially in rice fields, many households are not for 1+1> 2. The main reason is that the income of growing rice alone is too low. In addition, it is also because the cost of aquaculture alone is too high. The key is that there is no government subsidy. After the three-dimensional farming, many farmers dig ditches in the farmland Carry out stocking of aquatic organisms and change farmland into ponds. For three-dimensional farming, the aquatic organisms that really play a positive role in rice are not among the above-mentioned fish and shrimp species.
