Farmer in Deqing, Zhejiang Invents New Method of Rice Cultivation
Planting rice in paddy fields after raising soft-shelled turtles, keeping it inside insect-proof netting throughout the entire growing period... A farmer in Deqing County, Zhejiang Province, has invented a new method of growing rice that requires no fertilizer or pesticide. Not long ago, a green, pollution-free rice produced in Deqing and called "Mosquito Net Rice" aroused great interest; rice priced at 36 yuan per kilogram sold out in just over an hour, and many rice shops in Hangzhou even placed advance orders for 2008 stock. Why is it called "Mosquito Net Rice"? It turns out that this

Rice seedling raising is key: good seedlings mean half the rice is already grown, and strong seedlings lead to high yields.
Seedling-stage management for machine transplanting is key. Cultivating robust seedlings suitable for machine transplanting is the key to the success of promoting mechanized rice transplanting. "Good seedlings mean half the rice is grown, and strong seedlings lead to high yields." The quality of the seedlings plays an important role in the number of panicles, number of grains and grain weight in the later growth stages of rice. The basic requirements of mechanized transplanting for seedlings are overall uniformity and individual robustness, requiring that "a tray of seedlings has no tall and short ones, and a handful of seedlings has no thick and thin ones." High temperature and high humidity promote uniform emergence. Germinated rice seeds, after sowing, need to go through a period of high temperature and high humidity for seedling establishment.

Detailed Explanation of the Soft-shelled Turtle-Rice Rotation Ecological Farming Model
Generally, after 2 to 3 years of raising soft-shelled turtles, one season of rice is planted. In mid-May, juvenile soft-shelled turtles are stocked, with a size of about 180 g body weight and a stocking density of 500 to 1000 turtles per mu. They are fed soft-shelled turtle compound feed together with live fish, and are caught before the end of July the following year. After catching the turtles, late rice is planted from late July to early August. During the rearing process, aside from using quicklime and other drugs to clear and disinfect the pond, no antibiotics, chlorine preparations, or other chemical drugs are used. For disease prevention, Chinese herbal medicines such as Banlangen (Isatis root) are mostly used. Regarding rice cultivation techniques,
