When will the profitable soybeans (soybeans) be planted? It is not difficult to do a good job in these five points to achieve high yield!

Soybeans are common crops in China, which are planted by almost every family. They have a certain market prospect because of their easy planting and low investment cost. When will the profitable soybeans be planted? What are the planting techniques?

First, do you make money growing soybeans?

Soy not only refers to soybeans, it also contains black beans and green beans. Soybean is nutritious and rich, in which the content of protein is 2 times higher than that of pork and 2.5 times higher than that of eggs. The content of protein is not only high, but also of good quality. The amino acid composition of soybean protein is similar to that of animal protein, in which the ratio of amino acids is close to that needed by human body, so it is easy to be digested and absorbed. If you match soybeans with meat and eggs, their nutrition can be compared with that of eggs and milk, and even exceed that of eggs and milk.

When will soybeans be planted?

The planting time of soybeans varies according to the weather, and the planting time is generally divided into spring sowing and summer sowing. Spring sowing takes place before and after the Qingming Festival, and the harvest time is September (August of the lunar calendar). Summer sowing takes place after wheat harvest and is harvested from late September to mid-October. In addition, there is another kind of soybeans in the northeast that sows a little later, but has little to do with the harvest time. Spring soybean in northern China was sown from April to May, Huang-Huai-Hai summer soybean was sown in June after wheat harvest, and summer soybean in southern China was sown from May to early June and autumn soybean from the end of July to early August.

What are the planting techniques of soybeans?

1. Seed selection and treatment, it is best to select varieties that are about 5 days longer than the local growth period, requiring seed purity of more than 98%, purity of more than 97%, germination rate of more than 95% and water content of less than 13%. All seeds are coated before sowing. Before sowing, all the seeds were treated with 35% doxorubicin seed coating agent, and the seed dressing of soybean was 1.75 according to the proportion of medicine seed.

2. Select and prepare land, choose flat land or flat land, and wheat stubble and corn stubble with loose soil, good soil quality and good drainage can be selected. There are less than 5 soil blocks larger than 5cm per square meter, spelling depth 2~15cm, deep loosening depth 25cm above, reaching the state of waiting for broadcast.

3. Apply fertilizer scientifically, applying 15 tons of organic fertilizer per hectare (organic matter content is more than 80%), combined with soil preparation as base fertilizer. 175kg of chemical fertilizer was applied per hectare, including 125kg of phosphate, 25kg of urea and 25kg of potassium sulfate. Seed fertilizer was applied deeply or laterally, with 6-8cm from the seeds.

4. Precision sowing and sowing can begin when the local temperature stably passes through 7: 8 ℃. According to row spacing 75cm, interrow plastic film mulching seedling spacing 3cm, using special plastic film mulching machine precision sowing, fertilization, suppression, plastic film mulching can be completed at one time. 220000 ~ 250000 seedlings per hectare. The sowing amount per hectare is about 70 kg. So that the sowing is uniform without broken strips, the error of sowing rate is + 3%, the depth of sowing is 5cm, the error of line spacing is / 1cm, and the film mulching is uniform. The thickness and width of agricultural film should be 0.008 mm and 1 meter, and the amount of agricultural film is about 50 kg per hectare.

5. Chemical weeding, soil sealing treatment can be carried out 3 days after sowing, spraying the soil with 90% Acetochlor 800ml + 70% Saike wettable powder 150kg 300g, mixed with water 125kg 150kg.

Fourth, what are the points for attention in planting soybeans?

1. Temperature: because it is native to the tropics and likes the environment of high temperature and humidity, it has strict requirements on the temperature in winter and cannot survive the winter safely in areas with frost.

2, lighting: light requirements are not strict, like plenty of sunshine, but also withstand half-shade.

3. Fertilizer and water: for potted plants, in addition to adding organic fertilizer when potting, proper fertilizer and water management should be carried out in the usual maintenance process.

Generally speaking, it is still profitable to grow soybeans, but it is necessary to do a good job in the basic management of water and fertilizer, temperature and light, so as to improve the efficiency.
