Matters needing attention in the latest soybean planting

Soybean has strong adaptability to the environment, it is very easy to grow, and the survival rate of planting is very high. Naturally, we want to grow soybeans with high yield and good quality, so we need to master the correct planting techniques. So do you know what problems you need to pay attention to when planting soybeans? Next, let's take a look at the matters needing attention in soybean planting with the editor.

1. Time

We still need to pay attention to the time of planting soybeans. The planting time of soybeans in northern China is generally from the end of April to the middle of May, while soybeans in the south are generally planted from the end of March to early April every year. However, some areas can grow several crops of soybeans a year, that is, from January to May, but this is generally only applicable to areas with relatively mild climates throughout the year.

2. Density

Planting density has a great influence on the growth, yield and quality of soybean. Different planting areas have different degrees of fertility, different topography, and different soybean varieties, so the planting density we want to determine will change accordingly, that is to say, the planting density is not constant. Soil fertility is sufficient to plant 15000 to 20, 000 plants per mu, medium-fertility soil is generally capable of planting 20, 000 to 30, 000 plants per mu, and barren soil is generally 30, 000 to 40, 000 plants per mu. In fact, that is to say, the spacing between rows is generally 30 to 40 centimeters, and the spacing between plants is about 15 to 20 centimeters.

3. Chemical control

Many people may not understand what chemical control is, in fact, chemical control is the use of fertilization to regulate the growth of soybean plants. Soybean likes fertilizer, but in the process of its growth, we still need to control the amount of fertilizer and the scientific use of fertilizer. In the early stage of soybean growth, we can properly use nitrogen fertilizer to promote plant growth, but in the middle and later stage, we need to supplement phosphorus and potassium fertilizer, use as little nitrogen fertilizer as possible, avoid excessive growth and reduce soybean yield.

4. Ploughing

In the process of soybean growth, we also need scientific ploughing, which is also of great benefit to the growth of soybean. The first intertillage is usually when soybean seedlings and supplementary seedlings are planted, and this time we need to clean up the weeds in the field. The second intertillage is to loosen the soil for soybeans after planting survival, which can improve the soil permeability and promote the growth of soybeans. In the later stage, it needs to be ploughed according to the specific situation, but it should not be ploughed when flowering and podding.

5. Moisture

Soybean has a strong ability to resist drought, so it can be properly drought, but there must be no stagnant water or too much humidity in the field, which has a great impact on soybean. This means that we generally only need watering when it is dry or when the temperature is very high, but when there is more rain, we must drain it in time.

6. Picking leaves

After soybean blossoms and pods, we should pick leaves properly, which can reduce the consumption of nutrients, let the centralized supply of nutrients, promote the growth of soybean pods and improve the quality of soybean. At this stage, if there is a lack of nutrients, then it is easy to appear the phenomenon of soybean not full, serious reduction in yield and quality. But we usually remove the denser leaves, or some of the leaves at the bottom.

We must pay attention to the above points when planting soybeans, otherwise the soybeans planted will have an impact more or less. For growers, the decline in output and quality is directly related to their economic benefits, so it is very important.
