Planting method of pollution-free rice

Abstract

The invention discloses a planting method of pollution-free rice. The planting method comprises the following steps of selecting rice seedling beds, applying a botanical pesticide, applying a base fertilizer, and then performing exposing to the scorching sun for 5-7 days; airing rice seeds for 1-2 days, soaking the aired rice seeds with limewater of which the mass percentage is 4-8% for 1-5h, then performing thorough cleaning, and soaking the cleaned rice seeds in water of which the temperature is 30-45 DEG C until the rice seeds have white buds so as to obtain germinated rice seeds; performing rotary tillage on the rice seedling beds exposed to the scorching sun, performing ridging, then sowing the germinated rice seeds, and after 40-50 days, obtaining rice seedlings; applying the rice base fertilizer to the selected paddy field, and then transplanting the rice seedlings; and after 30-35 days of transplanting the rice seedlings, performing topdressing of nitrogen-phosphorus-potassium composite fertilizers, after 55-60 days of transplanting the rice seedlings, performing topdressing of urea and potassium humate, and after 65-70 days of transplanting the rice seedlings, spraying a traditional Chinese medicine extract to the leaves of the seedlings. According to the planting method of the pollution-free rice, provided by the invention, the yield of planted rice is high, and the obtained unhulled rice is few in pesticide residues and good in mouth feel.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a planting method of pollution-free rice. 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.

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 Northeast region, the Yangtze River B...
