At present, the planting area of ​​soybeans has been expanded in China. In order to ensure the high quality and high yield of soybeans, it is necessary to solve some problems in the cultivation process of soybeans in order to meet the needs of soybeans for everyone's life. Let's take a look at the problems and solutions in the soybean cultivation process. First, the main problems 1.1 Responding to the problem The crop nature of soybean determines that it is not suitable for heavy seeding and cultivating. The heavy crop refers to the same crop planting year after year. The soybean planting area in the three northeastern provinces is more. The northeast planting is mostly unable to carry out annual plant rotation due to climate relationship. The phenomenon of heavy cropping of soybeans is very common, leading to problems such as reduced production and reduced quality due to continuous cropping. Yingying refers to soybean planting in the next year, which means that it is alternately planted with other crops. The same species also brings about the problem of reducing production and degrading. According to the survey, the yield reduction of heavy seed is increasing year by year. In many areas, the number of years of continuous cropping has increased by 40%, and it has increased pests and diseases and reduced the fat content of soybeans. The main causes of reduced yields are the invasion of pests and roots in the roots, and the environmental problems caused by the secretions, decomposition products and microbial sedimentation of the roots of the plants, which accelerates the degradation of the soil. Soybean heavy planting will increase the degree of degradation of pests and diseases, reduce the yield and quality of soybeans, and have a certain impact on the economic benefits of crops. 1.2 Land preparation and fertilizer ratio problem With the advancement of technology production, high-tech agricultural planting equipment has come out one after another. China's soybean cultivation equipment mainly uses small tractors. If unreasonable use of small tractors, it will reduce the thickness of the land cultivation layer and reduce the permeability of the soil. Floods and land droughts have seriously threatened the growth of crops. When the soil is compacted by small tractors, it will bring harmful substances into the soil, causing soil erosion. At present, the cultivation of crops in China is still using chemical fertilizers. The use of farmyard manure is difficult and requires the support of manpower and material resources. Convenience, the difference in fertilizer ratio will make the nutrient content of soybeans deviate, affecting the quality of soybeans. 1.3 Problems with the use of pesticides Pesticide is sprayed during the growth of plants, but many pesticides compete with soybean seedlings for soil, nutrients and moisture in a short period of drug efficacy, affecting soybean yield and growth rate. The ratio of the medicament should be carried out according to the instructions to ensure the balance of the dose. The amount of the drug will bring harm to the soybean, and the medicament should be fully diluted. Rational use of pesticides can be beneficial to the growth of soybeans. Second, the solution 2.1 Scientific planting In order to reduce the waste of land resources and soil erosion, it is necessary to carry out standardized and unified planting. Standardized planting is to concentrate the land and carry out large-scale mechanized planting. The advantage of centralized and unified planting is that land can be refurbished after harvesting, so that after the winter freezing and spring melting, the soil can reach the role of loose soil and facilitate farming. If land refurbishment is not carried out, the surface of the land will be Cracks will occur, so when the land is loose, it is necessary to ridge in time to provide timing for planting. When planting, the frequency of production and depression can be appropriately increased, the degree of looseness of the land can be increased, and the temperature of the soil can be increased. The use of chemical fertilizers should be controlled to reduce the number of uses. Long-term use of chemical fertilizers will reduce the organic matter content of the soil and is not conducive to the growth of soybeans. 2.2 Reasonable ratio fertilizer The best ratio fertilization method is the soil testing formula. The base fertilizer is added with the decomposed farmyard manure. The dosage is more than 15 tons per hectare. In some land with more serious degradation, the amount of farmyard manure should be increased to about 20 tons per hectare. This method of fertilization can not only solve the problem of insufficient nutrient content and de-fertilization of the land, but also reduce the rate of decline of organic matter in the soil. The use of NPK can also increase the trace elements required for plant growth. Consolidate the structure of the soil. The use of chemical fertilizers should be divided into layers and deep. At the same time, the use efficiency of fertilizers can only be maintained for a period of time. This requires planters to set a good cycle for topdressing. The dosage can be consulted by professionals. 2.3 Scientific and rational use of drugs Pests and diseases have always been an inevitable problem in plant cultivation. When selecting a drug, it is necessary to pay attention to the date of production and the batch number of the commercial product, to judge the quality of the drug, and the agent will affect the germination rate of the seed. In the process of drug dilution, Strictly follow the proportion of medication used in the instructions. In the process of spraying pesticides, it is necessary to avoid high winds and foggy weather. The types of pesticides are various. It is necessary to select the types of pesticides suitable for plant growth. Pay attention to the temperature and humidity of the air when spraying, and ensure the effectiveness of the drugs. Third, the conclusion There are still many problems in the cultivation of soybeans. Therefore, it is necessary to carry out scientific rotation planting. In the process of compounding fertilizers, the fertilization scheme is continuously optimized. The selection of drugs should ensure the quality, and the farmyard manure can increase the organic matter content of the soil. In addition, the use of herbicides is inevitable, increasing plant yields and reducing pests and diseases. The implementation of these methods can effectively solve the problems existing in the current soybean cultivation to ensure the high quality and high yield of soybean.
