New method for cultivating river crab in rice field

Abstract

The invention relates to a method for cultivating river crabs, in particular to a new method for cultivating river crabs in a rice field. The method comprises the following steps of: selecting appropriate rice and river crab varieties for crab cultivation in the rice field, excavating a crab trench, arranging an escape-preventing facility, temporally cultivating crabs in a vinyl house, planting rice, stocking juvenile crabs, carrying out rice cultivation management and carrying out river crab feeding management. The method provided by the invention has the following two distinguishing characteristics: firstly, before the juvenile crabs are stocked in the rice field, the juvenile crabs are temporally cultivated in the vinyl house, thus time for cultivating the river crabs can be about one month earlier compared with the time for cultivating the river crabs in the rice field directly, growth period of the river crabs is prolonged, specification of the river crabs is increased by about 20%, yield is improved by 5-10kg, and sale price and economic benefit of the river crabs are greatly improved; and secondly, the variety of the planted rice is kenyu 88 which is a new rice variety cultivated by Binhai agricultural research institute of academy in Hebei province and is applicable to crab cultivation in the rice field, and the variety of the rice has high resistance to fertility, hard straw, high lodging resistance, high resistance against disease and high yield.

AI Technical Summary

Benefits of technology

It was found that when wearing shoes on crops like corn during harvesting, it can be lifted up from its roots without damaging them or causing damage. By raising these fish into an indoor environment called Green House at around 1-5 months ago, they are able to grow faster and produce more products compared to traditional methods such as feeders used alone. Additionally, Kenyu' s New Cranberry varieties have stronger root systems and resist diseases better due to their ability to absorb water effectively.

Problems solved by technology

The technical problem addressed in this patented text relates to improving crops grown for food or other purposes without reducing their nutritional value through increasing yields from traditional methods such as adding more nitrogenous chemical compounds like ammonium sulfate (AMS) during water rearing operations.
