1. Prenatal variety selection is the basis for improving the whole rice rate. It has been proved from the long-term work practice that the rice varieties of the same kind have different roughness and the rate of whole fine rice, and the quality of the inferior and high quality varieties in the same kind of rice is different, and the proportion of the percentage of the whole precision rice is also very different. It can be seen that the selection of rice varieties is the basis for improving the head rice rate and the first condition for improving the head rice rate. Therefore, agriculture related departments should guide farmers to actively adjust grain planting structure and vigorously develop high-quality rice production.


Two. Field management is the key to improving the whole rice rate. The whole growth period of rice is about 150 days. During the growth period, rice field management is particularly important. First, the supply of fresh water in the field should be moderate, especially the last field water should not be overlooked. We should not only consider dry harvesting for harvesting, but also irrigate the last field water. The two is that the fertilizer should be supplementing the appropriate amount. Three, the disease and insect pests of rice should be prevented and controlled early. In addition, rice can be harvested at the top 90% of the grain, which can better reduce the imperfect grains, increase the roughness and improve the rice grain rate.


Three. Post harvest scientific storage and storage is the guarantee for improving the whole rice rate. In order to ensure that the whole rice rate of rice can reach the national standard, we must achieve "one change, two prevention and Three Guarantees" in the management of post harvest harvest and storage. "One change": that is to change the threshing method. Instead of threshing grain and threshing grain, we can reduce grain damage and increase brown rice outside the valley. "Two prevention": that is, rice should be exposed to explosion and sun drying. During the daytime exposure of rice, the grain crack rate is increased because the temperature difference between day and night is too large. If the semi dried rice is exposed to the rain, the moisture of the rice grains inside and outside the grain is not consistent, which leads to the increase of the burst waist of the rice and the increase of the content of the broken rice.
