Soft-shelled turtle-rice rotation model

Generally, after breeding turtle for 2~3 years, planting rice for one season. Young soft-shelled turtle is bred in the middle of May, the specification of the young soft-shelled turtle is about 180g, the stocking density is 500 - 1000/mu, the soft-shelled turtle compound feed is matched with fresh fish, and the soft-shelled turtle is caught before the end of July of the next year, and late rice is planted from the end of July to the beginning of August after catching soft-shelled turtle. Feeding process, in addition to quicklime and other drugs to disinfect the pond, do not use antibiotics, chlorine preparations and other chemical drugs, disease prevention when more than the use of Chinese herbal medicine such as Isatis root. With regard to rice cultivation techniques, due to the fertile soil in the turtle pond, it is necessary to select high-quality varieties with short stems and lodging resistance, such as Yongyou No.1, 98~110, etc. Secondly, in terms of cultivation techniques, it is necessary to focus on "anti-lodging" and adopt "two-control and one-prevention techniques", i.e., one control fertilizer, no fertilizer in the whole growth period; the second control water, the method is to control seedlings early in the field, and when the number of seedlings reaches 80% in the late tillering stage, the rice roots are deeply rooted; and the later dry and wet irrigation is used to prevent lodging. The rice planted can reach the standard of pollution-free rice by only controlling insects but not preventing diseases.
