Treatment method for improving internal quality of hybrid rice

Abstract

The invention belongs to the technical field of rice planting, and discloses a treatment method for improving the internal quality of hybrid rice. The treatment method for improving the internal quality of the hybrid rice comprises the steps of selecting and dividing a test field, ploughing and preparing the field, applying fertilizer to the field, carefully selecting and treating seeds, sowing the seeds and raising rice seedlings, transplanting the rice, spraying a 'Gelinmei' nutrient and the like for planting. According to the treatment method for improving the internal quality of the hybridrice, the internal quality of the hybrid rice can be greatly improved, the content of various essential amino acids is increased, and the novel social demand for high-quality food can be well met. Byadopting the method of selecting the optimal nutrient application amount, the quality of the rice is improved, the head rice rate can be increased, and processing and value increasing of rice products are promoted; by using the method, the internal quality such as the content of the essential amino acids of the rice can be greatly improved, and the income of rice farmers is increased; and meanwhile, due to the fact that the head rice rate is increased, processing enterprises can also increase the processing economic benefits.

Description

technical field [0001] The invention belongs to the technical field of rice planting, and in particular relates to a treatment method for improving the internal quality of hybrid rice. Background technique [0002] In the 1970s, the world faced the dual pressures of decreasing arable land and growing population, and the pursuit of high yield was the main goal of world grain production research. With the invention of hybrid rice, China created the miracle of feeding 23% of the world's population with 9% of the world's arable land. Because hybrid rice has strong growth vigor and high biological yield, it absorbs relatively more fertilizers. Therefore, growers tend to think that the higher the yield of hybrid rice, the greater the need for fertilizer, and often blindly increase the amount of fertilizer applied. On the one hand, it causes a huge waste of energy, and it is also not conducive to the stable and high yield of large areas, and it is difficult to ensure the quality ...

AI Technical Summary

Problems solved by technology

[0004] Through the above analysis, the existing problems and defects of the prior art are: the cost of planting hybrid rice increases, the appearance quality and taste quality decline, and the internal quality (essential amino acid content, etc.) and processing quality do not improve or break through.

[0005] The difficulty of solving the above problems and defects is: in terms of rice breeding and cultivation, high yield and high quality have always been a pair of contradictions that are difficult to coordinate

In terms of difficulty, firstly, it is difficult to accurately determine the amount of fertilization; secondly, it is difficult to accurately grasp the optimal application time of physical and chemical technology; finally, it is difficult to ensure simultaneous improvement of yield and quality in the use of physical and chemical technology
