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:
The High Speed Mixing Machine consists of bottom feed blades and high-speed waste blades. The feed blade paddles continuously feed the bottom material along the barrel wall. The high-speed crushing blades completely crush the materials sent by the blades, so that the materials are circulated into a spiral shape, so as to achieve the purpose of uniform mixing of the materials in a short time. There is no difficulty in cleaning.
Equipment Characteristics:
1). Appearance design is reasonable and safe. The structure of this machine is simply, so it's convenient to clean and maintenance.
2). The paddle is strong and durable, and the material is harmless to people.
3). The plate of the whole machine is heavier than ordinary machines and has a longer service life.
4). The mixing speed and mixing time can be changed according to customer`s request.
5 ).The mixture is even, no small group or small piecesare left .The mixing time is short, it takes only 3-4 minutes to mix 50kg-100kg powder each time.

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.
