The key to "storing grain in technology" is to improve quality and increase efficiency.

In order to realize "storing grain in technology", we should take the improvement of quality, efficiency and competitiveness as the core goal, and the corresponding science and technology support policies should focus on how to improve the comprehensive production capacity of agriculture and how to achieve sustainable development. efforts should be made to solve the problems restricting cost-saving, efficiency, safety, quality improvement and circular development, and effectively enhance the competitiveness of the industry.

The wheat harvest has just ended, and it is another bumper harvest year. The news of measuring the yield of key fields and experimental fields has also been coming from various places, and the record of per unit yield of wheat has been constantly refreshed. In the face of the record of per unit yield, some people feel that this is only a small-scale high-yield problem, and it is of little practical value. The author believes that tackling key problems with high yield has its irreplaceable value, but agricultural science and technology can not be satisfied with the increase of output in the new period, and the focus should shift from too much pursuit of output to pay more attention to quality, efficiency and competitiveness.

It should be noted that it is a normal phenomenon that there is a big difference between the output of experts in the experiment and the actual harvest of farmers in the field. Expert yield is the maximum yield of varieties under the premise of good methods, fertile fields and other optimal matching, but also reflects the actual yield potential that can be achieved under field conditions, and has its irreplaceable value. Increasing grain production is a systematic project, and there is still a long way to go from the experimental field of the scientific research team to the contracted land of farmers. it is necessary to combine improved varieties, good methods, fertile land and good people, and it is necessary to open up the three major links of agricultural scientific research, agricultural technology popularization and farmers' training.

At present, the contribution rate of China's agricultural scientific and technological progress is 56%, the level of agricultural mechanization of major crops is 63%, and the contribution rate of varieties to the increase of unit yield is 43%. It can be said that the development of agricultural science and technology in China has achieved remarkable results, in which the land output rate has increased significantly, but the resource utilization rate and labor productivity are not satisfactory.

The per unit yield of major crops in China is close to or even exceeds the advanced level of the world, but the agricultural labor productivity is far lower than the advanced level of the world, which shows that "one leg is long and the other is short". The data show that the per unit yield of rice and wheat in China has reached the level of developed countries, and the per unit yield of corn has reached the level of moderately developed countries, but China's agricultural labor productivity is only 47% of the world average. In recent years, the imports of cotton, soybeans, sugar and other varieties with low labor productivity have continued to increase.

At the same time, the utilization rate of resources needs to be improved. Although the area of cultivated land in China is less than 10% of the world's, nearly 40% of the world's chemical fertilizers are used; the use of pesticides per unit area is 2.5 times the world average; although agricultural film has increased the yield per unit area, half of it remains in the soil, resulting in "white pollution." If we continue to increase the input of pesticides, chemical fertilizers and agricultural films, the rural environment will be difficult to bear and the safety of agricultural products will be difficult to guarantee.

The above two aspects have put forward new requirements for the development of agricultural science and technology. However, the overall layout of agricultural science and technology in China is still not balanced, and it is difficult to adapt to the new requirements. From the perspective of investment in agricultural scientific research, there are more scientific and technological forces related to crop yield, such as the cultivation of new agricultural varieties and the prevention and control of diseases and insect pests, but less scientific and technological investment in efficient cultivation, resources and environment, processing of agricultural products, quality and safety, and so on. the latter is precisely the key to the improvement of agricultural quality and efficiency; from the perspective of the transformation of scientific and technological achievements, agricultural scientific research and promotion are out of touch with industrial development, and there is a lack of integrated connection mechanism. The goal of many researchers is to complete the project and pass the variety approval, regardless of whether the variety is suitable for promotion.

Throughout the world, the initial goal of agricultural science and technology is to pursue output, and then gradually pay equal attention to production development and ecological protection. For our country, in the historical stage when the total grain output is low and the problem of food and clothing is mainly solved, the "output" index is the most important. In recent years, the index of "good quality and high benefit" has become more and more important. What farmers care about is not the highest harvest under ideal conditions, but the average harvest under ordinary conditions. They hope that after adopting the new technology, they will not only have high output and good taste, but also save labor and, more importantly, be economically cost-effective.

"storing grain in technology" is an important aspect of the national food security strategy. In the future, we should take the improvement of quality, efficiency and competitiveness as the core goal, and the corresponding science and technology support policies should focus on how to improve the comprehensive production capacity of agriculture and how to achieve sustainable development. Efforts should be made to solve such problems as cost-saving, efficiency, safety, quality improvement and circular development, so as to effectively enhance the competitiveness of the industry. Only in this way can we connect scientific and technological research and development, agricultural technology popularization, and farmers' training, and make the output in the laboratory become the output of farmers more smoothly. the transition from the seemingly "uneconomical" of small-scale demonstration fields to the possibility of field production is "more economical".
