Detailed Explanation of Key Soybean Field Management Techniques
When growing soybeans, management work is crucial. Soybean yield is closely tied to how well management is carried out, so we must never neglect management when planting. However, many growers do not have a specific management plan when planting and do not know how to manage. Below, the editor brings you soybean field management techniques. Let's take a look!
1. Timely thinning
Thinning work is very important for soybean growth. The purpose of thinning is to distribute soybean seedlings reasonably, prevent seedlings from affecting each other's growth, which leads to excessive consumption of nutrients and water, uneven seedling growth and reduced soybean yield. Therefore, thinning should begin when soybean seedlings grow to two true leaves. Remove weak seedlings, dead seedlings and pest- or disease-affected seedlings to ensure a full stand.
2. Timely topdressing
Fertilizer nutrients are indispensable for soybean growth. If the soil fertility of the planting plot is insufficient, then topdressing should be done reasonably according to the soil fertility and the growth of the seedlings. Generally, nitrogen fertilizer is the main type, but it should not be excessive, otherwise it easily causes excessive vegetative growth. During important periods such as soybean flowering and pod setting, and regreening, appropriate topdressing should be applied to meet the nutritional needs of soybean growth and improve planting benefits.
3. Cultivation and weeding
Cultivation and weeding are also an essential management task when growing soybeans. We should cultivate regularly to improve soil permeability and enhance the soil's nutrient absorption capacity. Weeding can prevent weeds from competing for the nutrients needed for soybean growth, concentrating nutrients on the soybean plants. Therefore, special attention should be paid in summer, as this can not only concentrate nutrients but also improve field permeability and increase yield.
4. Foliar topdressing
Foliar topdressing is intended to prevent soybeans from suffering nutrient deficiency, which leads to insufficient nutrition and reduced yield. When planting, we must always observe the growth of soybeans. If lodging is found in soybeans, foliar fertilizer should be sprayed promptly. This increases stem thickness, dwarfs the plants and reduces lodging. During important growth periods such as full flowering and pod setting, appropriate regulators can be sprayed to promote dry matter accumulation and increase yield.
5. Pest and disease control
Pests and diseases cause great harm to soybeans, so we must pay attention to pest and disease control when planting. Otherwise, it can easily lead to reduced soybean yield and lower planting benefits. Pest and disease control should focus on prevention, strengthen management, do a good job with water and fertilizer, and enhance soybean growth capacity. After soybeans develop disease, identify the main pests and diseases promptly and then apply the right treatment to avoid the spread of the disease and an expanded affected area.
The above is a brief introduction to soybean field management techniques. Soybean field management work is very important, so everyone must not underestimate it, so as to increase yield and protect your own planting benefits. That is all for today's introduction.
