Method for planting rice in Procambarus clarkii culture pond

Abstract

The invention discloses a method for planting rice in a Procambarus clarkii culture pond. The method comprises the steps of carrying out standard pond reconstruction, carrying out pre-culture preparation, carrying out juvenile Procambarus clarkii stocking, carrying out high-straw rice transplanting, carrying out planting and culturing management, carrying out commercial Procambarus clarkii culturing and fishery and carrying out high-straw rice harvesting. According to the method, rice planting is introduced to aquaculture ponds firstly, the Procambarus clarkii culture pond is subjected to simple engineering reconstruction, Procambarus clarkii, rice and water plants are organically combined so as to realize the mutualism of the Procambarus clarkii and the rice, the Procambarus clarkii is used for carrying out soil loosening and insect damage removing on the rice, and the rice absorbs nutrient elements, such as N and P, in water, so that the water for culture is purified, habitation and shelter sites are provided for the Procambarus clarkii, a good growth environment is created for the Procambarus clarkii, and the quality of the Procambarus clarkii is improved. The method disclosed by the invention is simple and convenient in operation and is suitable for being popularized to shrimp and crab culture ponds, the whole course of production has no need of medication, produced rice and Procambarus clarkii are high in quality, and the economic benefit increased per mu is more than 1,500 RMB, so that the method has great social and economic benefits.

Description

technical field [0001] The invention relates to a method for planting rice in an aquaculture field pond, in particular to a method for planting rice in a crayfish breeding pond. Background technique [0002] Crayfish (Procambarus clarkii), belonging to the crayfish family and the genus Procambarus, is native to northern Mexico and the southern United States. Introduced to my country by Japan in 1929, it has become an important resource of freshwater shrimp in my country, and is widely distributed in the middle and lower reaches of the Yangtze River and the Huaihe River Basin. In 2014, the national crayfish aquaculture area exceeded 8 million mu, the aquaculture output was about 660,000 tons, and the total aquaculture output value reached 15.86 billion yuan. The crayfish industry has formed a relatively mature industrial chain link of "seed breeding-healthy breeding-processing, catering, intermediary, culture-sales logistics". The consumption of crayfish by diners is hot, es...

AI Technical Summary

Problems solved by technology

In the pond culture mode, the planting of aquatic plants is mainly used as the bait source and activity place for crayfish and the water quality adjustment of the culture. The production of crayfish and the proportion of high-quality commercial shrimp in this mode are relatively low; while the rice field culture mode requires simple engineering on the farmland Crayfish farming can only be carried out after transformation. Although additional crayfish products have been obtained and the comprehensive economic benefits of single rice planting have been improved, the actual rice planting area of ​​farmland has decreased and the original output of rice has been reduced.
