Soybeans are traditional agricultural crops in the country, growing in a longer history and with higher levels of cultivation among farmers. However, due to the effects of planting techniques, soil, climate, prices, etc., soybeans are becoming less productive, affecting the incentives of farmers to grow and the balance between supply and demand in soybeans markets. It is therefore necessary to improve planting techniques, to prevent and control the incidence of falling flowers and to increase the yield of cultivation. It is a common phenomenon for soybeans to adjust their own metabolism balance in growth and development, but it has a direct impact on soybean yields and thus on the economic performance of farmers. Usually, a soybean can open 100 flowers, but the drop rate is 70 to 80 per cent, and only 20 to 30 plants can be grown. The high incidence of soybean falling is linked, on the one hand, to the characteristics of soybean crops themselves and, on the other hand, to factors such as over-intensity of cultivation, inadequate soil moisture supply, nutrient disorders, climatic conditions, pests and diseases。
Technology for soybeans cultivation
The soybean cultivation techniques have a direct impact on soybean growth and production, thus ensuring the quality of cultivation. The first is to select good seeds, mainly soybean seeds, that both guarantee the purity of the seeds and have a high gestation rate. At the same time, suitable seeds are selected according to the place and time of planting. The second is the optimization of the farming process, which, since soybeans cannot be burdened, has to be split between maize and potatoes, usually after one soybean has been planted, which takes two to three years to grow a new soybean. It is also necessary to work well, using mechanically sound planting methods, to improve soil softness and soil water retention, to provide a good space for soybeans to grow and to develop their roots. Once again, good field management. The planting of soybeans by farmers after the land does not mean that the whole process of planting is completed, but that it is necessary to replant, water, fertilizer, etc。
Ii. Methods for preventing soybeans from falling into the ground
2. 1 rationally adjust soybean density
A reasonable planting density can ensure both that soybeans draw impacts from the soil and that light energy is used efficiently and land resources are used to the maximum. The planting density of soybeans is not clearly defined, but is adjusted to the variety, time and fertility of the soil, usually between 15,000 and 20,000 acres. For example, long, strong soybean varieties are thinner, leaving room for soybean growth; thinner and thinner。
2. 2 increased application of fertilizers
It is well known that plants require a large amount of nutrients to grow and that the available nutrients in the land do not meet the needs of soybeans throughout their growth cycle, and that they need to be applied in a timely manner, both to reduce the loss of soybeans due to inadequate nutrition and to make them more full. 1) the application of base fat before soybean cultivation; 2) the flattening of 500 kg of soybean ash and 25-30 kg of phosphorous fertilizer per acre, and their coverage on land where soybeans have been planted, thus increasing soil fertility, making the soybean plant stronger, more flowering and more condensed; 3) the application of 5 to 6 kg of urea per acre, 7 to 10 kg of potassium chloride, after the soybean blooming, to meet the nutrient needs of the soybean. Leaf-faced fertilizer is also sprayed during flowering periods, such as potassium phosphate at 3% g/kg。
2. 3. High in time
Tops are mainly directed at bean varieties with unlimited cheeks, while those with limited cheeks are prohibited. At the top, by definition, is the removal of the top of the soybean neck, which is about 2 to 3 cm, mainly to make the plant thicker and to prevent it from growing to a high level, affecting the growth of the beans. Up tops, mainly during the flowering of soybeans, may be required to retreat in the clear。
2. 4 drought and drainage preparedness
The soybeans depend on water throughout their growth cycle, and demand for water varies over time. For example, during flowering seasons, soybean plants grow rapidly, so water is in high demand, and when the soil is less watered during the period, this can lead to a significant loss of the herb, so that the water is properly replenished in accordance with local weather。
2. 5 prevention and control of pests and diseases
Despite their strong resistance to pests and diseases, soybeans, when affected by pests and pests, inevitably affect their growth, so they need to be treated differently. For example, aphid pests, with a 40 per cent dose of oxidated fruit milk; soybeans, with a 50 per cent marathon emulsifier; 100 kg dilution with a 100g concentration; and purple spots, with 500 times the dose of desenzin。
2. 6 reasonable rotation
The soybeans are taboo and need a rational rotation to reduce the area under heavy cultivation. After two to three years, the soybeans are grown after the land has been restored. It is also necessary to employ deep-tilled and well-ploughed soil for soybean root nutrients, thereby making the plant stronger and soybean resistant to disease and inversion。
Summary
In order to reduce the number of soybeans falling and ensure soybean production, it is necessary to use soybean habits in a scientific and rational manner, both to avoid overdensity affecting the lightness of the leaves, to adjust the moisture in the soil, to avoid drought affecting the absorption of soybean nutrients and to avoid flooding leading to the decay of soybean roots. Fertilization, pest prevention and minimizing the impact of adverse factors on soybean products are also required。
