Soybeans are not only our main food crops, but are also important oil crops, cash crops and one of the most cultivated food crops in the country today. This paper is aimed at providing technical support for the promotion of soybean production in the country by introducing soybean cultivation techniques and pest control techniques in the soybean areas of the region。
Key words: soybeans; planting techniques; pest control
At present, with the further development of our agricultural economy, soybeans, an important food crop and cash crop, have a significant impact on the development of our agricultural economy in different parts of the country. Since soybeans are more suitable for cultivation in different parts of the country, which can lead not only to the development of regional agriculture but also to the economic benefits of agricultural industries, soybeans are grown in a wide range of areas. However, soybean cultivation and pest control technologies have a direct impact on soybean production and require continuous improvement in technical measures during actual planting. The following is a summary of soybean cultivation techniques and pest control techniques, in conjunction with soybean cultivation in the soybean region of daehing-ahning province。
Technology for soybeans cultivation
1. 1 selection and sowing
At present, soybean varieties are relatively large and the most suitable soybean varieties need to be selected according to soil conditions in the region. Seeds are selected before planting and bad seeds are removed. The choice of soybean varieties should be somewhat chill-resistant in the case of the booming areas, given their relatively high latitudes and the short duration of the frostless period. In the process of soybean cultivation, in order to avoid the problem of herbicides affecting germinate growth rates before and after soybean cultivation, it should be ensured that each seed is grown at a reasonable depth. It is worth noting that due to the relatively rapid temperature changes in the booming areas, planting times need to be rationalized according to climate change characteristics to avoid delays in planting。
1. 2 field management
Field management of soybeans should include fertilization, weeding and irrigation. Specifically, before soybeans are grown, the land is fertilized to ensure balanced soil fertility. In the process of soybeans growing, the soybeans are followed up in a timely manner. During soybean sowing, additional fertilizers such as potassium chloride and urea are applied to ensure that soybean seedlings can take their roots to the greatest extent possible, in order to compensate for the lack of soil fertility and to provide adequate nutrition for soybean soybean seasons, flowers and drums. Second, weeding is determined on the basis of soybeans cultivation; irrigation needs to be combined with the climatic characteristics of the north-east region to avoid soybeans being arid or over-irrigated。
1. 3 harvest
Soybeans, as a high-yielding crop, have extensive areas of cultivation in the booming areas, and actual harvesting needs to be done mechanically. However, due to the different type of seed, harvesting takes place with reasonable selection of the harvest table, roller rollers, etc. After the harvest has been completed, soybeans are preserved in ventilated, ventilated, tidal-proof, heat-proof environments after full drying。
2 pest and pest management technologies
2. 1 common pests
A relatively large number of soybean pests are common in the region of the highlight, such as soybean aphids, soybean frost, soybean roots, soybean brown spots and soybacterosis. For example, soya froste is an infestation of the soybean seed system, which is more likely to be caused by cold weather when seeding; soy root scabs are mostly caused by soil morbid infections, with relatively wide range of parasitic diseases, making their treatment more difficult。
2. 2 control techniques
2. 2. 1 soybean frost
The cause of the disease is low-temperature cultivation and soybean varieties, which require rational selection before soybeans are grown to ensure that the soybean varieties are resistant to the virus. There is also a need to make reasonable choices about the timing of soybeans. The relatively low temperatures in the boom-and-pine areas require that soybeans be grown in such a way that the timing of planting is reasonably determined in the light of the region's physical conditions and that the problem of seeding at low temperatures is avoided。
2. 2. 2 soybean decay
In areas where soybeans are grown, more than 3 a rotation with other crops; after soybeans are harvested, sick strains in the soil are removed in a timely manner, the soil is torn down and the source of the bacteria is reduced; at least two times the soy root decomposition is relatively difficult to treat, with a focus on monitoring areas where soy root decomposition has occurred, with maximum improvement in soil permeability during soybean cultivation, leading to a large number of new roots. In addition, microbicides were sprayed once or twice in the early stages of the disease and 50 per cent of the huf humid powder and 50 per cent of the huf bi-wettable powder were allocated for treatment at a ratio of 3. 32。
3 concluding remarks
Soybeans, as an important cash and food crop in our country, have a great impact on the development of our agricultural economy. In different areas, appropriate planting and pest control techniques need to be selected according to soil conditions, natural climatic characteristics, etc. This paper describes soybean cultivation techniques and pest control techniques in the region and hopes to provide some lessons for soybean cultivation in other regions。
