Method for planting pollution-free rice through rice-duck mutualism

Abstract

The invention discloses a method for planting pollution-free rice through rice-duck mutualism. The method comprises the steps that botanical pesticide is applied in a rice field, and the rice field is exposed to the sun; base fertilizer is applied to the rice field exposed to the sun, and rotary tillage is carried out; rice seeds are added into carbendazim liquid medicine to be soaked, added into clean water to be soaked and thoroughly flushed, sodium selenite is added for soaking after the seeds are added into water, the temperature is kept at 35-45 DEG C till the rice seeds sprout, and the rice seeds are thoroughly washed and placed to obtain the sprouted rice seeds; ridging is carried out 30-50 days after rice field rotary tillage, and the sprouted rice seeds are sown; urea and nitrogen phosphorus and potassium compound fertilizer are applied 10-20 days after sowing, rice seedlings are obtained 40-50 days after sowing of the sprouted rice seeds, the rice seedlings are transplanted into the rice field, and ducks are placed in the rice field after 10-15 days. According to the method for planting pollution-free rice through rice-duck mutualism, the planted rice is high in yield and strong in disaster resistance, the obtained rice is small in pesticide residue, meanwhile, high-quality duck meat is obtained, and economic benefits are improved.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a method for planting pollution-free rice through rice-duck co-cultivation. Background technique [0002] Rice is one of the three most important food crops for human beings. It originated in tropical Asia. After being widely planted in China, it gradually spread to all parts of the world. About 50% of the world's population uses rice as a staple food. According to different methods, rice can be divided into indica rice and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice. Paddy rice is called rice or rice after shelling the rice grains. There are various ways to eat rice, such as rice, rice porridge, rice cakes, rice cakes, rice noodles, rice wine and so on. In addition to being edible, rice can also be used as an industrial raw material for wine making and sugar refining. The main rice producing areas in my country are mainly the Nor...
