Problems solved by technology

[0002] Natural river crabs are rich in nutrients and have become a delicacy in people's catering. In recent years, with environmental changes, natural river crabs have been decreasing day by day, which can no longer meet people's needs. Therefore, the technology of using rice fields to raise river crabs in captivity is quietly developing. With the improvement of rice production, the growing environment is polluted due to the increasing use of pesticides and chemical fertilizers, which has an extremely adverse impact on the cultivation of crabs in rice fields. With the improvement of people's health awareness, the demand for pollution-free green food is more urgent. The traditional method of cultivating river crabs in rice fields can no longer meet the needs

Embodiment 1

[0019] In the method of the present invention, the paddy field enclosure mode has adopted plastic film material, and paddy field is divided into several parts of same area, and every part 5~10 mus is advisable, then maintains in every enclosure circle, can be beneficial to management like this, In addition, it is easy to carry out ecological adjustment for several relatively independent small ecosystems in a large ecological environment, thereby reducing the management workload and effectively reducing the losses caused by the escape of river crabs.

Embodiment 2

[0021] The anti-escape wall built around the rice field can be made of plastic film, asbestos tiles, and glass materials with a thickness of 0.08 to 0.1 mm as the wall, which is buried in the soil by 10 centimeters (centimeters), so that the above-ground anti-escape wall is 50-50 cm high. 60 cm (cm), the outer edge is fixed with bamboo poles or stumps, the angle of the wall is slightly inclined inward, and the four corners form an arc shape, and then the inlet and drainage pipes are installed, and the pipe head is tightly wrapped with a net. Set up two blocks, and the width of the ridge around the paddy field should be more than 80 centimeters (centimeters).

Embodiment 3

[0023] One week before the stage of spreading crab seedlings, fertilization should be stopped in the paddy field, and the paddy field water should be drained and dried for one day to achieve the purpose of disinfection and cleaning the field and facilitate the growth of crab seedlings.

Abstract

A method for rearing crab by ecological regulation belongs to the kind of ecological rearing in paddy field. With the technique development of paddy field comprehensive utilization, rearing crabs in paddy field has been public against that traditional method of production takes damage of chemical pollution on the field and crabs while can not meet the demand for green food. Based at the aim aforementioned, said invention fertilizes 50 % at the base of field and fresh water into field to cultivate crabs supported by plants and animals in water with additional bait, and whose excrement can be use as organic fertilizer for field. The invention performs no damage on the fields in the full process from cultivation period to capture period by adjusting the density of crabs, and performs harvest of paddy with high production of crabs.

Description

Technical field: [0001] The invention relates to a method for cultivating crabs in paddy fields by using ecological control, which belongs to the category of paddy field ecological species breeding. Background technique: [0002] Natural river crabs are rich in nutrients and have become a delicacy in people's catering. In recent years, with environmental changes, natural river crabs have been decreasing day by day, which can no longer meet people's needs. Therefore, the technology of using rice fields to raise river crabs in captivity is quietly developing. With the improvement of rice production, the growing environment is polluted due to the increasing use of pesticides and chemical fertilizers, which has an extremely adverse impact on the cultivation of crabs in rice fields. With the improvement of people's health awareness, the demand for pollution-free green food is more urgent. The traditional method of cultivating river crabs in rice fields can no longer meet the need...
