In order to achieve high yield, lobster in rice field needs to meet four major requirements.

Delicious lobster is mouth-watering, but many people stop drooling at the thought of its birth and growth place. It is said that the dirtier the lobster is, the more it can grow. In fact, many lobsters are raised in rice paddies. Yes, you heard right. Not only can you raise fish and Loach in rice fields, but now you can raise lobsters, and there are four major requirements for raising lobsters in rice fields:

Raising lobster in rice fields

First, drying the fields. Drying the field should be light, and the time should be short, there is no need to drain the water completely, the water level should be lowered to the surface of the field, and it is best to roast the field once before entering the field. When you find that the lobster has an abnormal reaction when drying the field, you should inject water immediately.

Second, fertilizing. Base fertilizer should be fully applied at one time, mainly rotten organic fertilizer. Topdressing should be applied a small number of times, it is best to apply half of the field first, and then the other half of the field.

Chemical fertilizer harmful to crayfish is prohibited. Fertilizer is generally applied once a month, each time 5 kg of urea or 10 kg of compound fertilizer per mu. When applying chemical fertilizer, first drain the shallow field water and concentrate the lobster in the field ditch, ring ditch and temporary culture pond. In addition, topdressing is prohibited during the molting period of crayfish. Try to reduce the number of fertilizers during the growth of rice.

Third, medication. Choose pesticides and biological agents with high efficiency and low toxicity, pyrethroids insecticides are prohibited, and the frequency of pesticide use is reduced as much as possible. Pesticide application should strictly grasp the safe concentration of pesticides to ensure the safety of lobster. It is required that the medicine should be sprayed on the rice leaves and should not be sprayed into the water as far as possible to avoid harm to the lobster. Add the field water to 20 cm before application, and change the water in time after spraying. Avoid using drugs in rice fields during the moulting period of crayfish.

Fourth, temporary rearing of seedlings. As soon as the lobster enters the rice field, it will crawl everywhere, destroying the live rice seedlings. Therefore, in the construction of the field project, a temporary culture pond with a depth of 1.2 meters and a slope ratio of 1 to 2.5 of the area of the rice field is excavated, and the crayfish is temporarily raised to live rice seedlings and then put into the field.
