Crayfish greenhouse seedling culture device and paddy field breeding circulation method

Abstract

The invention discloses a method for crayfish greenhouse seedling culture and paddy field breeding circulation. The method comprises a greenhouse, a skeleton, a temperature adjustment device, a paddy field, an oxygenating pump, a channel, a feeding pool, a breeding pool, a drainage pump, a seedling release pool, a water changing device and a gate. The method disclosed by the invention is beneficial in that a technical system for ecological and efficient crayfish culture and seedling breeding in the paddy field is formed; emergence of seedlings is realized in batches; the crayfish culture in the paddy field is suitable for screening of rice varieties; economic benefits are outstanding; thanks to omnivorous eating habits of crayfishes, the crayfishes can wipe out worm eggs and larvae in the paddy field during the culture so as to relieve occurrence of insect attacks in the paddy field, reduce pesticide dosages and pesticide application times of the paddy field and improve quality safety of agricultural products; and the crayfishes can eat a lot of straws, so that wet land water quality of the paddy field can be effectively improved, and an agricultural ecological environment of our country can be protected effectively. Through breeding of the crayfishes in autumns and winters, a land utilization rate can be effectively increased; farmers' income can be increased; and social and ecological benefits are very obvious, so that the method is suitable for generalization.

Description

technical field The invention relates to a crayfish seedling raising device and a paddy field cultivation method, in particular to crayfish greenhouse seedling cultivation and paddy field cultivation circulation technology, belonging to the field of circular cultivation. Background technique Crayfish has been naturalized as an aquatic species in my country. It is an important aquatic economic shrimp species, which can expand the breeding area and alleviate the contradiction between supply and demand in the crayfish market. The implementation of paddy field cycle planting can effectively improve the water quality of paddy field wetlands, which is conducive to the protection of my country's agricultural ecological environment. At the same time, taking advantage of the crayfish's mixed feeding habits, crayfish can eliminate eggs and larvae in rice fields during the breeding process, thereby reducing the occurrence of insect pests in rice fields, reducing the amount and frequenc...
