With the continuous improvement of living standards, the quality of food and food has become more and more important. The quality of rice is no exception and it is highly valued by people. The government implemented a high-quality rice project, and the second phase of the project will also start. However, the development of rice industrialization is still relatively backward. The breeding, production and processing of high-quality rice varieties still lag behind. It is necessary to strengthen the breeding and processing of high-quality rice in order to improve the quality of rice in Ningxia. Adapt to the needs of the two high-quality agriculture, realize the increase of farmers' income, increase efficiency of enterprises, and promote the healthy development of Ningxia rice industry.
In Ningxia, a number of high-yielding large ear varieties such as Ningjing No. 9, Ningjing No. 19, and Ningjing No. 23 were bred to make a significant contribution to the improvement of rice yield in Ningxia, but these high-yielding species have high chalkiness and chalky area. Large, mature is not good enough, and the appearance of rice grains is poor and does not meet the needs of the market. Although the newly-selected Ningjing No. 24 and other high-quality, high-yield new varieties have performed outstandingly, the planting area has been limited, which has affected the scale efficiency and industrialization of rice cultivation. The rice samples of each sample were processed and sampled using a rice grinder, followed by a detailed study.
Through the sampling test of polished rice, the quality of rice is controlled not only by the genetic gene of the species itself, but also by the cultivation and management measures. Increasing the planting density will reduce the brown rice rate, polished rice rate, and polished rice rate, increase the chalkiness rate, reduce the transparency, and increase the amylose content and gel consistency. In the application of fertilizers, nitrogen has the greatest influence on the quality of rice. In general, the application of nitrogen fertilizer can increase the brown rice rate and milled rice rate, especially the ratio of polished rice, reduce chalky area and chalkiness, increase protein content, and make rice processed. The appearance and nutritional quality have been improved. At the same time, applying nitrogen can also reduce the amylose content, but it also tends to harden the gel consistency. In the rice production in Ningxia, the cultivation measures are basically aimed at high yields and do not consider the impact on rice quality.
