Embodiment 1

[0025] A kind of rice crab symbiotic culture method, comprises the following steps,

[0026] Set up temporary raising ponds: Set up temporary raising ponds according to one-tenth to one-ninth of the size of the cultivated paddy field, and the depth of the temporary raising ponds is 80cm. Crabs are initially purchased as megalopa, and the purchase time is roughly the end of April and the beginning of May. At this time, the megalopa are cultivated into crab seedlings and placed in a temporary breeding pond for temporary rearing. This time is from May to June.

[0027] Temporary pond treatment and crab temporary cultivation: Disinfect the temporary pond and plant aquatic plants, pour water into the temporary pond until the water depth is 30cm, and put the crabs in the temporary pond for temporary cultivation; the disinfection method can be sterilized with lime, per mu The dosage is 80-100 jin.

[0028] Farming paddy field setting: dig crab ditch around the ridge of the aquacultu...

Abstract

The invention relates to the technical field of crab cultivation, in particular to a symbiotic culture method of rice and crabs. The symbiotic culture method includes: setting a temporary culture pond; treatment of the culture pond and temporary culture of the crabs; setting up of the rice field for culture; setting up escape prevention facility; rice planting and crab culture; crab and pond management, wherein the feeding method in the pond management includes: preparing fodder according to 3.5-4% of the weight of the crabs, releasing the fodder on a fodder table on a regular basis, checkingwhether the crabs are shelled or not every day, stopping feeding each time the crabs are shelled, increasing the amount of feed after shelling is completed, preparing the fodder according to 6-8% of the weight of the crabs when the crabs are shelled for the fourth time, and increasing the number of daily feed releases. The symbiotic culture method has the advantages that rice planting is combinedwith crab culture to form the symbiotic ecological culture model of rice and crabs, the dependence of rice on the use of chemical fertilizer is avoided, green food supply is formed, and the income offarmers can be greatly increased.

Description

technical field [0001] The invention relates to the technical field of crab cultivation, in particular to a method for symbiotic cultivation of rice and crab. Background technique [0002] With the continuous innovation of modern agricultural technology, agricultural planting and aquaculture are combined with each other, rationally combined, using the shallow water environment of the paddy field, and cultivating aquatic products while growing rice. Aquatic products can eat pests and weeds in rice fields, and their feces can also provide nutrients for rice, forming a green farming and planting model. [0003] Crab is a kind of armored reptile, also known as hairy crab and hairy crab, which is a well-known delicacy in China. Its chelicerae are used for feeding and fighting against enemies, and the inner and outer edges of the palm are densely covered with hairs, hence the name mitten crab. Hairy crab is a delicacy that people love. It is not only delicious but also has high ...
