The main controlling factor for the yield and quality of rice is heredity, but the environment in which it is grown also has a certain impact on yield and quality. Reasonable application of fertility is an important measure for high quality and high yield in rice. Different nitrogen,phosphorus,zinc proportioning trials were set up to carry out this research, aiming to explore the effects of nitrogen, phosphorus, zinc and their combined application on rice yield and quality, so as to provide scientific basis for rational fertilization of rice. During rice quality research, rice sampling was performed using an inspection rice mill. Add Wechat to give you more professional information: A lip gloss tube is a small, cylindrical container used to hold and dispense lip gloss. Lip Gloss Empty Tubes.It typically has a twist or click mechanism at the bottom that allows the user to push up the lip gloss from the tube and apply it to their lips.Empty Lip Gloss Containers. The tube is often made of plastic or metal and is compact and portable, making it easy to carry around in a purse or pocket. The top of the tube usually has a small applicator, such as a brush or sponge, that the user can use to apply the lip gloss smoothly and evenly. Lip gloss tubes come in various sizes, colors, and designs, catering to different preferences and styles.

After the rice is fully mature, each plot is harvested separately, dried after threshing, and the yield is measured. Take a certain amount of rice, and check the roughness of the electric roughing machine, and check that the rice mill is white and then tested. Rational application of N, P and Zn facilitated the increase of rice yield and amylose content, while the protein content of rice was the highest in treatment and increased by 26.80% compared with the control, indicating that increasing nitrogen fertilizer is beneficial to increasing protein content in rice and increasing Applying zinc fertilizer on the basis of nitrogen fertilizer is more conducive to increasing protein content in rice, which may be due to the synergistic effect between nitrogen and zinc, but whether this needs further study.
Nitrogen nutrition had the greatest impact on rice yield. Zinc had greater effect on rice yield than phosphorus. With the increase of nitrogen and phosphorus levels, rice yield increased at first and then decreased, indicating that insufficient or excessive nitrogen and phosphorus were not favorable for rice. With the increase of yield, with the increase of zinc level, the rice yield showed a clear upward trend, indicating that increasing zinc fertilizer is beneficial to increase rice yield.
After testing the white rice milled rice, it was found that the protein content of rice is the main indicator of nutritional quality. The level of amylose content is closely related to the viscous, softness, glossiness and other food quality of rice. This study shows that : The effect of nitrogen, phosphorus and zinc on rice protein and amylose content is: nitrogen> zinc> phosphorus. With the increase of nitrogen application, the protein content of rice gradually increased.
