Soybean planting time and method, soybean planting time and method

1. Soybean planting time.

The northern spring soybean type is sown in April-May. The soybean type was sown in June after the wheat harvest. The southern summer soybean type is generally from May to early June. Autumn soybean type is sown at the end of July to early August.

Second, soybean planting methods.

1.Selection of seeds. At present, the seed market is also relatively complex, with a wide variety of soybean seeds.

When choosing soybean seeds, growers need to buy them at a regular seed station first. In addition, they need to choose soybean varieties that are resistant to local growing conditions. Before sowing, it is better to manually select seeds and remove some seeds of poor quality.

2.The choice of land. After selecting the seeds, we need to think about the land. Before planting, we must take care to clear the land. We can also turn the land over and apply some nutrients to the land.

3.Seeding method. There are also many sowing methods for soybeans, such as narrow row dense planting, wheat interplanting, and on-demand sowing.

Therefore, when choosing the sowing method, it is necessary to combine the actual local situation and choose the sowing method according to local conditions. In addition, planting soybeans in a reasonable density can also increase yields.

4.Field management. The main work is fertilization and nutrient supplementation.

Soybeans have a high demand for phosphate fertilizers from seedling stage to flowering stage. Timely application of phosphate fertilizer can ensure the growth of rhizobia and improve the nitrogen fixation capacity of soybean. Soybeans are relatively less resistant to fertilizer damage.

When applied, it is better to separate the seed fertilizer from the soybean seeds. The seed fertilizer can be diammonium phosphate, and the dosage per mu is about 8 kg. However, growers who are in a position to do so recommend soil testing and formula fertilization.

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.

The soybean planting time varies depending on the weather, and the planting method includes soil selection, field preparation, deep soil ploughing, seed selection, and management points.

1. The planting time of soybeans changes according to the weather.

The general sowing time is mainly in the spring and summer seasons, the Spring Festival is around the Qingming Festival, the harvest period is around September, and the summer sowing is harvested from late September to mid-October. In the north of China, it can be sown in April or May, the Yellow Sea is generally sown around June, and in the southern region, it is generally sown between June and July.

Second, the planting method of soybeans.

1. Choose the soil, the field for planting soybeans should choose fertile soil, convenient drainage and irrigation, no pollution, the most suitable for planting soybeans, to master the time of crop rotation, sowing from stubble, otherwise it will seriously affect the yield of soybeans, and at the same time, soybean diseases, insect pests, will also increase, which is extremely unfavorable to the growth of soybeans.

2. Tidy up the field, choose the planting field to tidy up, clean up the weeds, rotten leaves, and withered plant branches and leaves in the field to the corner outside the field for destruction, and then evenly sprinkle the farm manure in the field to dry and dry for 7 to 8 days, which can increase the stamina of the field soil and make the seeds grow better.

3. Deep ploughing of the soil, the use of large agricultural machinery for deep ploughing of the soil, the depth of the cultivated land is about 30 cm, and then leveling with farm tools, ridge or furrow according to planting habits, these two methods can be chosen by themselves, the width of the furrow surface is 1 meter to meters, and the height is about 15 cm. The ground of the furrow should be well drained to facilitate future management, and the height of the ridge should be more than 15 cm.

4. Select seeds, there are many varieties of soybeans to select seeds reasonably according to the local soil conditions, you can buy them in the market vendors or seed dealers, and carry out germination and disinfection work in time after purchasing seeds, and the seeds can be soaked in water temperature for 4 hours to 8 hours, and the seeds are taken out for drying after the seed coat is slightly expanded.

5. Key points of management, the daily management method of soybeans is very simple, convenient to control the water, when the weather temperature is high, you can use a shade cloth to shade, watering to cool down, and do a good job of drainage in the rainy season to do not let a large area of water accumulate in the field.

Introduction of soybeans

Soybean is an annual herb of the genus Soybeanaceae in the legume family, with a height of 30-90 cm. Native to China, it is cultivated all over China and is widely cultivated all over the world. Soybean is one of the important food crops in China, with a history of 5,000 years of cultivation.

The soybean planting time is generally in April or May in the north, and the sowing is generally between June and July in the south.

1. Soybean planting time.

The planting time of soybeans changes according to the weather, but the general sowing time is mainly in the spring and summer seasons, the Spring Festival is around Qingming, the harvest period is around September, then the summer sowing is in late September to mid-October for harvesting. In the north of China, it can be sown in April or May, the Yellow Sea is generally sown around June, and in the south, it is generally sown between June and July.

2. Methods of soybean planting.

Choose soil: the field for planting soybeans should choose fertile soil, convenient drainage and irrigation, no pollution, such plots are most suitable for planting soybeans, but to master the time of crop rotation, do not sow from stubble, otherwise it will seriously affect the yield of soybeans, and at the same time, soybean diseases, insect pests, will also increase, which is extremely unfavorable to the growth of soybeans.

Tidying up the field: After choosing the planting field, it is necessary to tidy up the work, clean up the weeds, rotten leaves, and wilted plant branches and leaves in the field to the corner outside the field for destruction, and then evenly sprinkle the farmhouse fertilizer in the field to dry and dry for 7 to 8 days, which can increase the number of rocks and the stamina of the soil in the field so that the seeds grow better.

Select seeds: seeds can be soaked in water temperature for 4 hours to 8 hours, find that the seed coat has a slight expansion and then take out the seeds for drying, this is mainly to let the seeds wake up from the dormant period, dry and dry the seeds with liquid medicine or powder, so as to prevent underground pests from destroying the seeds, sowing can be done after the seed treatment is completed, and the seeds of soybeans do not need to germinate and then sow.

Key points for the management of soybean pod-setting stage

1. Control Wangchang.

In the peak flowering period, if the plant is relatively vigorous, it is necessary to control the growth. It is mainly sprayed with paclobutrazol, chlormequatin, uniconazole, etc., to control vegetative growth and promote multi-pods. The spraying of the growth control agent is mainly for the plots with sufficient fertilizer and water and the trend of vigorous growth, and the plots with weak growth should be supplemented with fertilizer and water, and the regulator to promote the growth of soybean should be sprayed.

For plots with high planting density, poor ventilation and light transmission in the field, vigorous growth of stems and leaves, and a tendency to flourish, 30 ml of 27% amine fresh ester methylpiperium water agent can be used to spray evenly with 20 30 kg of water, which can effectively control the growth momentum of stems and leaves, accelerate the delivery of nutrients to the flowers, and significantly improve the pod setting rate.

2. Spray foliar fertilizer.

In the flowering and podding stage of soybean, 30 ml of 10% trace element water-soluble fertilizer can be used per mu, mixed with 15 20 kg of water to spray evenly, which can quickly supplement boron, molybdenum and other micro-plum jujube elements, and significantly improve the podding rate.

There is no conflict between soybean control and foliar fertilizer spraying, for example, premature senescence will occur when there is no top dressing in some plots, or when the root system has poor absorption. In this case, top dressing is also required, such as potassium dihydrogen phosphate, 100 grams of water in a bucket of tung water, and boron fertilizer, which have the effect of promoting more pods, which is consistent with the purpose of spraying a wang control agent.

Soybeans are generally planted except in winter, but spring soybeans in the north are generally planted in April and May, while summer soybeans in the south are generally planted in May and June, and the latest autumn soybeans are planted in early August. When planting soybeans, it is necessary to choose fertile soil, and at the same time, it is necessary to ensure that the soil is soft and appropriate fertilizer when planting, so that soybeans can grow more vigorously.

Soybean planting methods and key points.

1. Soil

When planting soybeans, it is necessary to choose fertile soil, but before planting soybeans, the soil should be turned to make the soil loose, and it should be fertilized to provide nutrients for the growth of soybeans, which is conducive to the growth of soybean seedlings.

2. Start planting

When planting soybeans, the method of planting soybeans is to dig a small hole in the soil, water it several times, then put 3 to 4 seeds in each small hole, and fill the hole with soil at the same time, so that the soybean seeds are completely buried in the soil.

3. Supplement nutrients

In the later stage of large-scale soybean planting, it is necessary to apply farmhouse fertilizer, and after the soybean seedlings grow leaves, fertilizer is applied again, so that the soybean grows more vigorously.

Precautions for soybean planting.

In the process of planting soybeans, do not be too compact, usually each piece is about 15cm to 20cm apart. At the same time, we should pay attention to reasonable fertilization. Remember that soybean plants are resistant to drought and waterlogging, we usually water them once in drought, and take drainage measures during the rainy season.
