In rice cultivation, although the use of chemical fertilizers and pesticides can produce high yields of rice, it will also cause a certain degree of pollution to the ecological environment. If the rice cultivation method is not correct, some damage will occur. Therefore, the promotion of the use of rice cultivation techniques, in order to reduce the use of pesticides and fertilizers, to promote higher yields, can also promote the stable development of the rice planting industry.
1. Cultivation status of rice
In rice cultivation, dwarf rice and hybrid rice are generally dominant. The use of dry nursery technology can promote the improvement of rice performance and provide higher yields for rice. In rice cultivation, both early rice and late rice, under different conditions, the density of transplanting will gradually shrink. The number of seedlings present is not sufficient, which affects the actual yield and quality of rice, and can not promote rice production. Carry out. In rice cultivation, due to the simplification of fertilization, organic fertilizer can be converted into a mixed fertilizer, which ensures that some factors such as nitrogen, phosphorus and potassium are added to the fertilizer to ensure the overall production of rice is increased. During the rice production period, due to the lack of planting awareness of some farmers, the importance of drying the field was not recognized, which had a great impact on rice yield. Under the active development of China's agriculture, a large number of mechanical equipments have been applied, and human resources can be harvested for optimization and change, which not only improves agricultural production efficiency, but also provides greater economic benefits for its development, and can also replace pesticide weeding in the later stage.
Second, rice cultivation techniques
1. Selection
In rice cultivation, selection is very important. Seed selection will affect the actual yield and quality of rice, and will also have a great relationship with the later benefits, and even affect the soil structure. Therefore, we must pay more attention to the selection of seeds. Through the analysis of the selection angle, it is necessary to consider the quality and quality of the seeds. It is also necessary to analyze the various conditions such as the climatic environment, temperature environment and precipitation according to the actual conditions in the area to ensure the comprehensiveness of the overall situation. Under certain conditions, some tests can also be carried out to ensure that a large number of plants can be planted under reasonable conditions.
2. Cultivation
Rice cultivation can be divided into different links as a whole. There is a great connection between the various links, but it also has a certain degree of independence, which has a greater impact on the rate of success. Therefore, in order to ensure that Miaoqi and Miaozhuang are strong, it is necessary not only to rationally select the time for planting the seedlings, but also to strictly control the greening after cultivation, and to ensure that the survival rate and growth rate are promoted to a certain extent.
3. Seed treatment
In the process of treating rice seeds, the purity should be controlled above 98%, and the germination rate should be controlled above 95%. When drying and soaking the seeds, 13% of dilute brine can be used and effectively rinsed to ensure germination. It is also necessary to do a good job in pest control to ensure the full application of rice seeds.
4. Seedling treatment
In the early stage of emergence, it is necessary to heat and moisturize it, and also ensure that the film is removed in time to avoid air leakage. When hydrating rice, it also needs to be based on actual developments in the area. Too much water will have a great impact on the development of seedlings. Under normal circumstances, it is necessary to culture the seedlings at a natural temperature, and it is not easy to achieve temperature intervention. When a small number of seedlings are found to be insufficiently developed, they can be fertilized reasonably.
5. Balanced fertilization
The use of fertilizer will have a great impact on the development and growth of seedlings, and will also have a greater relationship with the quality and quality of the seedlings, ensuring an overall increase in production. However, the use of fertilizers will also have a great impact on the natural environment and the ecological environment. When used excessively, it will affect the balance and stability of the environment, and will also reduce other plants. Therefore, fertilization needs to be perfected under the guidance of science.
6. Water slurry management
In the management of slurry, it is necessary to keep the water layer after transplanting at 3~5 cm. It is also necessary to propose shallow water rejuvenation, to grasp the actual dry and wet conditions, to avoid over-drying and over-wetting, and to ensure that the water layer is controlled within a reasonable range as a whole. Achieving scientific water slurry management can also promote the improvement of rice efficiency, ensure the overall stability of the ecological environment, and promote the growth of rice to ensure the increase of production output.
7. Pest control
In rice cultivation, it is necessary to achieve good pest control. Under normal circumstances, the main diseases are rice blast and sheath blight, and it is necessary to control different diseases. In order to propose reasonable prevention measures, it is necessary to analyze the local ecological environment, the carrying capacity of drugs, and the ability to purify, and promote the realization of drug prevention and control. In daily work, it is also necessary to strengthen ventilation and promote the growth of rice.
Third, related methods to improve the efficiency of rice planting
In rice cultivation, do a good job in all aspects, promote the scientific rationality of production work, and improve the planting efficiency of rice. Therefore, based on the active discussion in the article, it is of great significance to rice cultivation in China [2].
1. Choose excellent varieties
In the actual planting of rice, the selection of excellent rice varieties can promote the increase of rice yield. In rice selection, its range is mainly concentrated on elite populations. Therefore, it is necessary to develop and promote the fine varieties of rice and focus on them. At the same time, it is necessary to propose reasonable rice cultivation methods to ensure higher economic benefits as a whole.
2. Promote pollution-free production technology
The modern society is constantly improving and developing. Due to the economic construction and the promotion of spiritual civilization, people's safety of food has generally improved. China is a big rice producing country, and it has become a topic of concern for people to increase rice production and production. In the current construction and development, many areas have not effectively promote pollution-free production technology, especially in some remote areas, and still rely on pesticides and fertilizers to obtain production. Under such production conditions, not only can not guarantee the yield and quality of rice, but also cause great harm to the environment and food. Therefore, it is very necessary to promote pollution-free production technology.
3. High-tech application
In agricultural production and planting, the use of science and technology can provide a powerful impetus for its development and is also a major condition in agricultural production. In order to improve the economic benefits of rice, it is necessary to effectively infiltrate based on science and technology to ensure the positive development and use of rice planting technology. At the same time, the application of modern science and technology can also optimize varieties, promote the scientific management of field management, ensure the overall benefits under these conditions of implementation, and optimize the current production environment to complete the progress and development of the rice planting industry.
Fourth, the conclusion
In the process of using rice cultivation techniques, it is necessary to select varieties with strong disease resistance according to the actual conditions of the area, and to ensure the rationality of breeding and strong seedling work according to certain planting time. At the same time, according to the actual growth of the seedlings, fertilization and irrigation should be done to determine the amount of water to ensure the increase of rice yield and quality.
