As the country's economy and society move forward, people's physical standards of living are rising, and the public's interest in food security is increasing. Rice, as a food that we eat all the time in our daily lives, has a very important effect on the quality and quality of our daily lives and our food security. After entering the new century, the country's agricultural industry has been restructured and the area under cultivation, which is our main food crop, has been declining in recent years. How to use limited land to produce more productive and better quality rice is a priority issue in the current phase of rice cultivation. The analysis and research on rice cultivation techniques have been carried out, mainly in the context of actual rice cultivation, and it is hoped that this study will contribute to some improvement in rice production and revenue generation.

The wide area of the country and the significant regional differences between the different conditions of light strength, temperature and humidity in different areas can have serious effects on the healthy growth of rice. At the same time, because, unlike their cropping systems in different areas, some of the rice is ripe for one year, some are ripe for one year, and others are ripe for three years, we need to use different rice cultivation techniques in different areas. Based on this, this paper has mainly undertaken analysis and research on high-yield rice cultivation techniques. One choice of the right rice varieties, as the country's science and technology continue to develop, and many hybrid rice varieties have been developed, in the process of rice production
3. If there is to be a real increase in rice production, appropriate varieties of rice should be selected in combination with the climatic and topographic characteristics of the land. The different species of rice have different growth characteristics, so that, in selecting rice varieties, due consideration should be given to the growth characteristics, productive potential, etc. Of the selected rice species, and that, taking into account the local climate and soil conditions, the most suitable rice varieties should be selected for cultivation in the region. In addition, for new varieties of rice, it is important that, prior to extension, local trials be conducted and that the most suitable varieties of rice cultivation in the region be selected according to the production and growth characteristics. Since rice cultivation begins with seedlings, seed treatment should be done during rice cultivation. First of all, in the course of work, we should do the seed screening. Pick out the particles and pests that exist in the seeds and make sure the seeds are big
Four, small and even, full of particles, can increase the purity of the seeds, suggest the rate of seeding after the planting of rice; and, secondly, grade the seeds. In the process, in order to ensure the integrity of rice seedlings, seeds will need to be graded and grown within an area of the same size, which will facilitate the development of field management; again, before seeding, sunbath treatment will be required. Put the seeds in a clear weather and dry them, which will facilitate the processing of the incoming seeds; and, finally, do seed sterilization. Using agents like multibacterium and so forth to mix seeds, to reduce the incidence of rice disease. Once the seed is processed, it can be seeded and planted. 3 the scientific fertilisation in rice cultivation is important to ensure that rice has sufficient growth power. But it's been fertilizing
The more fertilized, the better, the higher the yield. Because the demand for fertilizers in the long life of rice is not identical. In order to promote increased production and harvest of rice, it is necessary to provide the nutrients needed for its growth at different stages of its fertility. When we fertilize rice, we need to determine the amount of fertilisation based on soil formulas. Because soil fertilisation techniques allow for a thorough analysis of the lack of nutrients in rice over all periods of life, and then develop scientific fertilization plans based on rice varieties and the amount of fertilization required. This fertilization technique, a high-yielding cultivation technique that is currently being promoted internationally, reduces fertilizer use and soil sheeting in the context of a comprehensive supply of rice nutrition. The demand for moisture varies over different periods of growth, with fewer strains and water demands. Compare
6. Small, drought-resilient, suitable for growing in a relatively wet soil of 60% during this period, should be less or less irrigated. And after the paddy breakup period, the growth of parts of the paddy land is gradually flourishing, and the water demand is greater during this period, which should be irrigated in a timely manner, depending on the humidity of the paddy fields, but should be focused on the amount of irrigation, mainly running horse water. The growing demand for water from rice during the paddy poaching period, the time when irrigation should be effective, when drought has a serious impact on rice production, should focus on field irrigation. The focus of rice field management is on seeding, replanting, weeding and pest control during the paddy season. First of all, after the rice has sprung up, it should be timely to check the seedlings if they are found to be deficient or there is a severe loss
7. Second, in the process of growing rice, since weeds in the fields affect their healthy growth and absorb the nutrients of rice, weeds in the fields should be removed in conjunction with farming. During weeding, weeding can be done by choosing a chemical herbicide or by using artificial weeding. In selecting chemical weeding, weeding agents that can eliminate weeds and that do not affect the ecological environment of the field should be selected. At the same time, care must be taken to use the quantity and select the correct spraying method; and finally, in the field pest control process, in addition to planting the agent before planting, there is a need for pest control at all stages of rice growth, with a focus on pest control such as rusty, root disease, paddy lice, subterranean pests, and in the light of the previous occurrence of rice pests in the region, to select the appropriate treatment method and agent. 6 payback in due time
8. In the process of rice production, timely harvesting is also an important method and response to improve rice production and quality, by draining water from the fields during the first half of the harvest. And when more than 90 percent of the rice fields are made yellow and the seed grains are hardened, the harvest is possible. After harvesting, rice is dryed in time, and when the water meets the corresponding requirements, it can be stored or sold, and the harvest can be reduced appropriately for the medium- and long-term mature rice varieties.
