Background
The rice is a cereal crop of the genus oryza, the representative species is rice, the rice is native to china and india, and the rice is classified into indica rice and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice according to the types of the rice. The conventional rice and hybrid rice are classified according to the seed reserving mode. Other classifications, including paddy rice and floating rice, are made according to whether soilless culture is performed; dividing season rice and 'lazy rice' (overyear ratoon rice) according to the survival cycle; the rice is divided into common rice and giant rice about 2 meters according to the height; the method is divided into ordinary fresh rice and 'seawater rice' (actually, the rice mainly uses fresh water) according to saline-alkali tolerance. The rice is obtained by removing glume, the rice is called brown rice, the brown rice is ground to remove a rice bran layer, the rice is obtained, nearly half of the world population uses the rice as staple food, the rice can be eaten, wine and sugar can be used as industrial raw materials, and the rice hulls and rice straws can be used as livestock feed. The main production areas of Chinese rice are Yangtze river basin, Zhujiang river basin and northeast region. The rice belongs to direct economic crops, the rice is staple food of Chinese residents, the planting area of the domestic rice is 2.45 hundred million mu of normal rice, the planting area of the hybrid rice is 2 hundred million mu of hybrid rice at present, and the rice has important significance for increasing each minute of the rice yield as a population country.
