Soybean planting time and technology, soybean planting method and time

1.There are many varieties of soybeans that are planted at the time, and the sowing time varies depending on the variety and region. In general, spring soybean varieties are sown in February-May each year.

Earlier in Vietnam, summer-Huaihai soybeans were sown in June, southern summer soybeans were sown in May-June, and autumn soybeans were sown in mid-July. 2.Ploughing over the fields.

Before sowing soybeans, the fields used to grow soybeans should be thoroughly ploughed. Although soybeans are not very demanding on the land, the state of the land will affect the survival rate of soybean seeds. Therefore, we must remove debris and weeds from the land, break down the hardened clods and soil layers, and make the soil loose and breathable.

3.When sowing soybeans in the treatment of bean seeds, it should be adjusted according to the actual conditions of the soil and beans. If the soil is relatively moist, the soybean seeds themselves can be slightly wetter or slightly drier.

If the soil is relatively dry, moist seeds should be dried to prevent the moisture inside the soybeans from separating from the overly dry soil layer. 4.Daily maintenanceAfter the soybeans are planted, the fields should be inspected regularly.

When watering or fertilizing soybean seedlings, pay attention to removing weeds and weeds growing around soybeans in time. Soybeans are not competitive and are easily competed for nutrients by weeds. Therefore, it is necessary to weed frequently and do a good job in disease prevention and control during the flowering and podding period.

YellowBean seedsPlanting time and technology are:

1. Planting time.

There are many different varieties of soybeans, and the timing of sowing varies depending on the variety and region. Generally speaking, spring soybean varieties are sown in the period from February to May each year, the earlier in Vietnam, the summer Huaihai soybean is sown in June, the southern summer soybean is sown in May and June, and the autumn soybean is sown in mid-July.

2. Turning over the field.

Before sowing soybeans, it is necessary to thoroughly turn over the field used to plant soybeans, although the requirements of soybeans for the land are not very high, but the state of the land will affect the survival rate of soybean seeds, so it is necessary to remove the debris and weeds in the land, break the compacted soil clods and soil layers, and make the soil loose and breathable.

3. Bean seed treatment.

Soybeans should be adjusted according to the actual situation of the soil and the actual situation of the beans when sowing, if the soil is more humid, then the bean seed itself can be slightly moist or slightly dry, if the soil is relatively dry, then the moist seeds should be dried to prevent the over-dried soil layer from precipitating the water inside the soybean.

4. Daily maintenance.

After planting the soybean seeds, it is necessary to regularly inspect the field, and pay attention to the timely removal of weeds and weeds growing around the soybean seedlings when watering or fertilizing the soybean seedlings.

The competitiveness of soybeans is relatively weak, and it is easy to be robbed of nutrients by wild grasses, so it is necessary to weed frequently and do a good job in disease prevention and control when flowering and poding.

The planting time of soybeans is in months, and the planting techniques include seed treatment, sowing, planting density, fertilization management, etc., as follows:

1. Planting time

Soybeans are best sown in April in spring and June in summer, and it only takes four to five months for soybeans to grow and mature. Before sowing soybeans, it is necessary to soak the seeds in water for 10 hours.

2. Planting technology

1. Seed treatment.

If the storage conditions are not good and the seed moisture content is high, the bright branch can be sown after 2 or 3 days of sun-dried seeds, and remember to spread the seeds to cool down after drying. Rhizobia seed dressing should be carried out, and seed coating should be treated with seed coating.

2. Sow seeds. In the process of sowing soybeans, you can dig a shallow ditch with a distance of 30 cm in the soil, and then spread the soybean seeds evenly in the shallow ditch. In the process of sowing, it is necessary to ensure that there are more than two seeds in each hole, and the distance between each two holes is about 15 cm.

3. Planting density.

Planting soybeans should not be too dense, depending on the fertility of the soil. If the soil is more fertile, it should be planted less, and 1 mu of land should be controlled within 2000 plants; If the soil fertility is slightly weaker, 1 mu of field is controlled within 3,000 plants; If the soil fertility is poor, 1 mu of field is controlled within 4,000 plants, the plant spacing is between 15 and 20 cm, and the row spacing is between 30 and 40 cm.

4. Fertilization management.

Soybeans are suitable for growing in a fertile environment, after soybeans grow seedlings, they can provide nitrogen fertilizer, urea, when soybeans bloom and bear fruit, phosphorus and potassium fertilizer can be buried in the soil, and potassium dihydrogen phosphate can also be sprayed on the leaves.

Morphology and growth habits of soybeans:

1. Morphology: It is an annual herbaceous plant of the genus Soybeanaceae, 30 to 90 cm high. The protein content of soybeans is 35% to 40%.

The stems are stout, erect, densely covered with long brown bristles. Leaves usually have 3 leaflets; The leaves are veined, pubescent with yellow; petioles 2 20 cm long; leaflets broadly ovate, papery; The racemes are short and have few flowers and long ones with many flowers.

2. Growth habit: Warm-loving, seeds begin to germinate in 10 12, 15 20 is the most suitable, growth temperature is 20 25, flowering and pod-setting temperature is 20 28. Seed germination requires more water, and the soil moisture content is required to be 70% to 80% during the flowering period.

The fertilizer absorption of soybean before flowering is less than 15% of the total, while the flowering and podding stage accounts for more than 80% of the total fertilizer absorption.

Summary. Hello. The planting time of soybeans changes according to the different weather, and its planting time is generally divided into spring sowing and summer sowing.

Spring sowing is carried out around Qingming Festival, and the harvest period is September (August of the lunar calendar). Summer sowing takes place after the wheat harvest and is harvested from late September to mid-October. There is also a soybean sowing date in the Northeast that is slightly later, but the harvest date is not very relevant.

Spring soybeans are sown in April and May in northern China, summer soybeans in Huanghuaihai are sown in June after wheat harvest, and summer soybeans in southern China are generally sown from May to early June, and autumn soybeans are sown from the end of July to early August.

Hello. The planting time of soybeans changes according to the different weather, and its planting time is generally divided into spring sowing and summer sowing. Spring sowing is carried out around Qingming in the high demolition section, and the harvest period is in September (August of the lunar calendar).

Summer sowing takes place after the wheat harvest and is harvested from late September to mid-October. There is also a soybean sowing date in the Northeast that is slightly later, but the harvest date is not very relevant. Spring soybeans are sown in April and May in northern China, summer soybeans in Huanghuaihai are sown in June after wheat harvest, and summer soybeans in southern China are generally sown from May to early June, and autumn soybeans are sown from the end of July to early August.

Pre-sowing treatment of soybean 1, pre-sowing land preparation: soybean pre-sowing land preparation includes soil tillage and harrowing, raking, pressing, etc., different land preparation technologies are different before sowing, such as flat turning, ridge cropping, harrowing, subsoiling, etc. 2. Pre-sowing irrigation:

For the plots with poor moisture before sowing, soybean irrigation conditions can be irrigated once 1 or 2 days before sowing to soak the soil to facilitate seed germination after sowing. 3. Closed weeding: If the management of soybean large-scale cultivation is not timely, the weeds are seriously harmed.

4. Selected seeds: soybean seeds have high germination rate and germination potential, and the seedlings are neat and strong, so the diseased grains, moth-eaten grains, small grains, seedlings and broken petals should be sorted out before sowing. 5. Seed treatment:

Soybean soybean is commonly used in seed quantity, soxin sulfur or elixir powder or carbendazim plus fumei double or doujia carbendazim plus grams.

The specific time of planting soybeans should be adjusted in time according to the changes in the weather, mainly spring sowing and summer sowing. Spring sowing is usually carried out around the Qingming Festival, that is, in April to May, in the lunar calendar in August can be harvested, summer sowing is mostly carried out after the wheat harvest, about the middle to late June, not more than July at the latest, in September to October can be harvested.

Soybeans have a good adaptability, the general soil can be planted, in order to make it grow higher, do not replant, after the selection of land should be cleared, so as not to affect the growth of soybeans. Before planting, it is necessary to do a good job of fertilization, which can be applied to the soil after fermentation and decomposition, and then raked into the soil with fertilizer, and deeply turned according to the previous crop, the depth is usually 22-25cm.

When sowing, the moisture content in the soil should be about 22%, so that the seeds can absorb water and germinate normally, and it is difficult for the seeds to germinate if it is too dry. Sowing is generally a direct seed, planting at a spacing of 30-50cm, sowing the seeds into the soil and covering the soil, just wait patiently for it to germinate. If you want to transplant it, wait until the seedlings have grown to 4-5 cm.

Soybeans are generally sown in April in spring and May in summer, and in the process of planting soybeans, you can dig a shallow ditch with a distance of 30 cm in the soil, and then sow the soybean seeds evenly in the shallow ditch, and also need to ensure that there are more than 2 seeds in each hole, and the distance between each two holes is about 15 cm.

Before soybean cultivation, it is necessary to remove moldy grains, diseased grains, moth-eaten grains, small grains, straw grains and mutilated grains, and select seeds with uniform size and full grains according to the typical characteristics of the variety.

Soybean planting conditions.

The most important condition for soybean planting is temperature, soybeans prefer to grow in a warm environment, moderate temperature is conducive to the growth of soybeans, after the growth of the temperature shall not be lower than 6 degrees, the seeds will gradually germinate.

Soybean planting time.

Soybeans are generally sown in April in spring and May in summer, and after sowing, it only takes 4-5 months for soybeans to grow and mature.

2. Planting method:In the process of planting soybeans, you can dig a shallow ditch with a distance of 30 cm in the soil, and then sow the soybean seeds evenly in the shallow ditch, and you also need to ensure that there are more than 2 seeds in each hole, and the distance between each two holes is about 15 cm.

Soybean high-yield planting method.

1. Soil selection; Soybean high-yield planting, the land must be fertile, loose and breathable, normal drainage and irrigation and pest-free plots, can effectively improve soybean yield, but it should be noted that soybeans can not be cropped, otherwise it is easy to produce pests and diseases, affecting the growth of soybeans.

2. Fertilization of land preparation:After selecting the land, sprinkle farm manure, organic fertilizer and compound fertilizer, turn the soil about 30 cm deep, and then level it. Pick out weeds and debris in the field to avoid the presence of pathogens that harm the growth of soybeans.

3. Seed selection and planting:After selecting the seeds, the seeds should be germinated and disinfected, first of all, the seeds should be dried in the sun for 3-4 hours, which will help improve the germination rate of the seeds, and then the seeds should be soaked in warm water at about 40 degrees for about 5-6 hours before planting.
