Rice field and pond combined cultivation method of procambarus clarkii

Abstract

The invention provides a rice field and pond combined cultivation method of procambarus clarkii. The method includes the following steps: 1, constructing a rice field and ponds; 2, pouring procambarus clarkii species and transferring procambarus clarkii larvae; 3, conducting rice cultivation and management, 4, fattening the procambarus clarkii larvae and controlling pests and diseases; 5, catching adult procambarus clarkii while leaving and storing the procambarus clarkii species. According to the method, procambarus clarkii cultivation is uninterruptedly conducted for years while parts of rice are planted in the rice field, therefore, simple rice cultivation is achieved, little chemical fertilizers and little pesticides are used, rice diseases and pests are reduced, procambarus clarkii larvae cultivation in the farmfield is combined with procambarus clarkii fattening in the ponds, the commodity rate and yield of the procambarus clarkii are high, and rice field ecological planting and breeding purposes are achieved, that is, manpower and material resources are saved, the farmland utilization rate is high, economic benefits are good and natural ecosystems are effectively protected.

Description

technical field [0001] The invention belongs to the field of shrimp and rice breeding and planting, and in particular relates to a field-pond joint culture method for Procambarus clarkii. Background technique [0002] The main shortcomings of the existing shrimp-rice co-cropping technology are: 1. The number of shrimp seedlings is large in the early stage, and the shrimp seedlings are sold to make a profit. However, as the self-sufficiency of the shrimp seedlings of farmers gradually increases, the demand will become less and less; 2. After transplanting rice seedlings, the living space of shrimp in the ring ditch is too small, there are not many shrimps in the pond, and there are few shrimps in the second season; 3. The commercial rate of shrimp produced is not high, and the economic benefits are not particularly good. [0003] The main disadvantages of the existing pond special culture technology are: 1. The self-sufficiency of shrimp seedlings is not high, and shrimp seed...
