Organic rice cultivation method by utilizing farmland and rice chaff weeding

Abstract

The invention discloses an organic rice cultivation method by utilizing farmland and rice chaff weeding, belonging to the technical field of rice production. The method comprises the steps of: soaking in shallow water; ploughing for two times or three times; transplanting strong seedlings; broadcasting rice chaff; conducting later field management and other steps. In the method, drainage is required at first and then ploughing is carried out each time, which aims at carrying away sheathed monochoria herb without spouting and floating on the surface of a water level and seeds of chufa through drainage; the rice chaff fertilization faster improve the field temperature so as to create a good sprouting environment for weed seeds, and also can reduce the oxygen content under the surface layer, thus preventing the normal growth of the weed roots and achieving purpose of killing weeds, further increasing the content of organic matters, being beneficial to improvement of rice quality. The organic rice cultivation method can be popularized and applied in rice cultivation regions.

Description

technical field

[0001] The invention relates to the technical field of rice production, in particular to an organic method for suppressing the growth of weeds in paddy fields by using cultivated land and rice bran. Background technique

[0002] Rice plays a vital role in the staple food of human beings, and rice is in great demand, so it needs to be grown in large quantities. my country is a big country that produces rice, but rice bran rice cultivation has been studied and applied in Japan as a paddy field weeding and fertilization technology. The China Rice Research Institute and other units have also carried out research on the use of rice bran to control weeds in paddy fields. Rice bran returning to the field is safe and environmentally friendly, and it plays the dual role of fertilizer and medicine. The social and economic benefits are significantly higher than manual or chemical weeding. It is an ideal and practical technology for weeding in organic rice produ...
