How often should the water in the rice be added when the weather is hot and it doesn't rain?

China is a big rice consuming country with a large population, so the demand for rice is increasing. Planting high-quality and high-yield rice has become the main goal of agricultural development and the main task of rice planting. Focusing on the cultivation techniques of high-quality and high-yield rice can promote the yield, quantity and quality of high-quality and high-yield rice to a new platform and stage.

Therefore, for China's agricultural development, especially the cultivation and development of high-yield rice in agriculture, it can make outstanding contributions to the internationalization of all mankind. This paper introduces some important new techniques for planting high-quality and high-yield rice in recent two years, bypassing the traditional rice planting techniques that growers have been familiar with for thousands of years, and puts forward new methods for pest control of high-quality and high-yield rice and suggestions for later development.

In some areas with relatively backward agricultural facilities in China, there are many problems that need to be improved urgently. The main problem is that in the process of rice planting and development, only the test and planting of rice varieties are paid attention to, while the planting techniques related to rice planting are ignored. There is still no fundamental breakthrough in the development technology of high quality and high yield of rice production. This has greatly affected the economic benefits of rice planting.

At present, the research on rice planting technology in China is not comprehensive enough. The traditional thinking mode has limited the innovative exploration of rice planting, and at the same time, it has little publicity effect on popularizing known new planting technologies, and the yield and quality of rice planting have never reached expectations. There is no perfect scientific management system for rice planting technology, which leads to uneven rice quality and affects the development of rice in the whole planting economy.

China has a vast territory and diverse topography, spanning many climatic regions. The data shows that there are a lot of land available for development and utilization, but there are many problems in actual utilization. Affected by natural factors, many areas are not suitable for crop growth. Even if you try to plant, it is difficult to ensure the yield and quality of crops. Mechanized production is not applicable in many areas.

China has a large population and a great demand for food. However, with the rapid development of economy, a large number of cultivated land is occupied by other industries, and the grain output is constantly threatened. At the same time, people's requirements for the quality of life are getting higher and higher. After satisfying the problem of food and clothing, we pay more attention to improving the quality of life. In addition, under the pressure of foreign grain production technology, many countries use advanced production technology to cultivate high-quality varieties and improve the competitiveness of mayors/markets, which has a great impact on the development of China's agricultural market. Therefore, it is very necessary to cultivate high quality and high yield rice.
