What are the growing methods of soybeans? Methods and processes of soybean cultivation

Soybeans are suitable for planting in fertile soil, drainage and irrigation, disease-free plots, and the planting plots are leveled after turning 30 cm deep, and ridges or furrows are made after removing crop residues, weeds and large stones. Sowing is carried out after soaking and dressing, open-field soybeans are generally sown in summer, sowing by early-maturing soybean strip sowing method, sowing by late-maturing soybean hole sowing method, planting seedlings grow to 4-5 cm, planting spacing is 30-50 cm.

First, select the land and prepare the land.

Choose a plot with a fertile soil layer, drainage and irrigation, and no disease to plant soybeans, and level the soil layer after turning it 30 cm deep. Pick out the residues of previous crops, weeds and large stones in the field to prevent the presence of pathogens from harming the growth and development of soybeans. Then, according to their own planting habits, they decide whether to plant in ridges or furrows.

Second, soak seeds and mix seeds.

Soak high-quality seeds in boiling water above 40, soak for 5-6 hours, if you find that the seeds have risen water during the whole soaking process, you must immediately pick them up and dry them, get rid of the dormancy period of the seeds. Subsequently, the seeds are dressed with drugs to solve the internal germs of the seeds, prevent the damage of underground pests, and improve the seedling emergence rate.

Three, sowing. Early-maturing soybean varieties can be sown by strip sowing method, and late-maturing soybean varieties can be sown by hole sowing method. Open-field soybeans are generally sown in summer, that is, after the wheat is picked, and should not be sown too late, and sown before July at the latest, otherwise it will lead to a limited soybean yield.

When sowing, we should pay attention to manipulating the relative density of sowing, not too dense, to avoid affecting each other's growth and development, fill the soil and cover the film after sowing, moderate watering, and improve the seedling emergence rate of seeds. Planting is carried out until the seedlings are 4-5 cm long, with a spacing of 30-50 cm.

Fourth, cultivation technology.

After planting a week after planting the field to carry out the seedling or to make up the seedlings, to ensure that the seedlings are complete, after 5-7 days to carry out a soil weeding and fertilizer, at the same time to water once, the fertilizer can be mixed with compound fertilizer and urea solution after use. The second fertilization should be until the soybean is in full bloom and the pods are formed, at this time, the growth and development of soybeans must have certain nutrients, and at the same time, in order to better mellow the pods, it can add a little potassium fertilizer and phosphorus and potassium fertilizer. The most likely stage for soybean symptoms is the time when the pods are in full bloom, so in order not to reduce production, it is necessary to carry out flower and pod protection measures for soybeans, and spray with dimethoate pesticide milk.

Fifth, picking. Most of the pods on the top of the bean seedlings gradually turn light green, and at the same time, they can be picked when they are hard and not flat or broken when touched with the palm of your hand.

To choose fertile soil, such as humus, you should pay attention to the planting density when planting, you should pay attention to the spacing of planting, the planting temperature must be grasped at about 27 degrees, you must water and fertilize in time, and you must do a good job of irrigation and use appropriate pesticides.

Select some soybeans that can germinate, plant them in the soil at a certain distance, and then carry out strict fertilization and watering, so that the soybeans can germinate, and then strictly carry out pest control.

Two ridges and one furrow cultivation method, with seeds, distance cultivation method, with root seedlings, wave canopy cultivation method, these methods can be soybean cultivation very well, planting to pay attention to the amount of water, pay attention to pesticides.

To ensure that the bottom fertilizer is sufficient, the planting process must be timely loosening the soil, weeding, insecticide, but also pay attention to the density of planting, the depth of planting, to choose high-quality seeds, but also to do a good job of drainage.

Soybean planting seeds must be handled well, which can improve the germination rate of the seeds. First, before planting, full-grain seeds can be selected to bask in the sun, which can improve the growth potential of late soybeans. When planting, you can use about ammonium molybdate or rhizobia (usually 1 kg of seeds, 20 kg of seeds).

According to the experience of old rural farmers, the soybean nodules formed after seed treatment are much earlier, the growth is faster, the branching is early, and the seed setting rate and pod number are greatly improved.

Soybeans are an important cash crop, and in recent years, high-yielding soybeans have been cultivated in many places. Due to the immaturity of the technology, some soybeans can not achieve the expected effect, and the seedlings cannot emerge at the appropriate time after sowing, and the seedling growth is also harmed by diseases and insects, resulting in low soybean yield and poor quality. You know, if you want to have a high yield of soybeans, you must do your homework on land preparation, sowing, weeding and top dressing.

1. Land preparation. To grow soybeans, choose soil with good irrigation and drainage and deep soil. Before sowing, the fertilizer is evenly spread on the ground and deeply turned into the soil per mu, including 1-2 tons of high-quality farm fertilizer, 10-13 kg of phosphate fertilizer, 3 kg of potassium sulfate, and 1 kg of zinc fertilizer, and then the land is prepared.

2. Sowing. Sowing can begin when the ground temperature is stable at 7-8 cm, with a small row spacing of 10-12 cm. Its density should be determined according to the characteristics of soybean varieties, water and fertilizer conditions and cultivation methods, and the seedlings are generally 27-320,000 per hectare.

Adhere to the principle of "planting and fertilizer in separate boxes, not mixing, no contact between seeds and fertilizers after sowing, no replanting, no missing sowing, and continuous stripping" to ensure uniform sowing.

3. Weeding. Weeding is carried out 5-7 days before sowing after land preparation, and it is required to achieve uniform application, accurate flow, no weight and no leakage. If soybeans are not chemically weed before planting, chemical weeding can be carried out in the period between post-sowing and pre-seedling.

Fourth, foliar top dressing.

In the soybean flowering pod stage, appropriate topdressing can be carried out according to the specific situation of soybean. If the growth is poor, top dressing can be carried out outside the roots. If the soybean grows too luxuriantly during the flowering period and has a tendency to lodging, it can be sprayed with paclobutrazol, mequat and other dwarf stalk strengthening agents to promote soybean dwarf and balanced growth.

Isometric hole sowing cultivation, fine cultivation, etc. Isometric hole cultivation, seed cultivation according to the distance of the land; Intensive cultivation, calculating the time and temperature for sowing.

When planting, we must choose the soil is more fertile and wide land, and in the process of fertilization, we must choose farmhouse fertilizer, do not use fertilizer bought outside, and often prevent the occurrence of pests and diseases, water the plants more, if there are small insects, then we must spray insecticides in time.

The first is to choose the time to sow in June, and then to ensure the humidity of the soil, and to choose a warmer area, and to fertilize in time, and also to weed in time, fertilizer in time, and to ensure that the sun is sufficient.

The planting method and process of soybeans are as follows:

1. Location selection.

Soybeans prefer to grow on fertile, well-drained, deep soil, so choose loose, nutrient-rich soils and avoid planting on acidic soils or salty alkaline soils.

2. Seed treatment.

Before sowing, the seeds should be treated to remove pests and diseases and bad seeds, and then soaked, bundled or dried.

3. Sowing time.

Soybeans are generally planted in the spring, depending on the local climate and soil conditions. Avoid sowing too early or too late.

4. Fertilization. Soybean has a large demand for nitrogen, phosphorus and potassium, so sufficient basal fertilizer should be applied before sowing, and then topdressing should be carried out at the appropriate time during plant growth.

5. Growth management.

During the growth period, soybeans need to maintain sufficient moisture and suitable temperature, prune and weed appropriately according to the growth of the plant, and prevent the invasion of pests and diseases.

6. Harvest. Soybean harvesting generally takes place in the fall, preferably when the soybean husk crack rate reaches 80 to 90 percent. After harvesting, it should be dried or dried in time.

1. Land selection and land preparation: Choose a field with good drainage and irrigation for planting soybeans, and fertilize after turning 30 cm deep. 2. Soaking and dressing:

After soaking the seeds in warm water for 6 hours, remove them and dress them with insecticides. 3. Sowing and planting: early-maturing varieties are planted in strips, and late-maturing varieties are planted in holes.

4. Field management: apply fertilizer 2-3 times to seedlings to promote the growth of stems and leaves.

1. Land selection and land preparation

To plant soybeans, we should choose a field with rich organic matter content, no pests and diseases, and good drainage and irrigation, and then dig 30 cm deep into the field, break up the soil clods, remove weeds and stones, and then apply rotten farmhouse fertilizer and organic fertilizer to the field to improve the fertilizer content of the soil.

2. Soaking and dressing:

Before planting soybeans, the seeds with round particles and no damage should be put into warm water at 40 degrees, constantly stirred until the water temperature is cooled, so that the seeds are heated evenly, and then stop stirring, soak for 6 hours, and then remove the seeds, mix the seeds with insecticides and dry them.

3. Sowing and planting

When planting soybeans, different sowing methods should be selected according to different varieties, early-maturing varieties can be planted in strips, late-maturing varieties are planted in multiple holes, in the process of sowing, soybean seeds should be evenly sown in the field, covered with soil and compacted and watered, and then covered with plastic film to keep warm and moisturized.

4. Field management

After soybean seedlings emerge, it is necessary to plough and weed, turn the soil shallowly to promote root growth, and then remove weeds in the field to reduce nutrient consumption, and apply 2-3 times of rotting farmhouse fertilizer or urea for soybean seedlings to promote the growth of leaves, and when the temperature is too high, the seedlings should be sprayed with water to cool down and avoid leaf drying.

To plant soybeans, first of all, the selected plot should be turned deeply, and an appropriate amount of base fertilizer should be applied to the soil, and the plot should be divided into compartments after leveling, and then the selected soybean seeds should be sown into the soil according to a certain plant spacing, and the soil should be kept slightly moist after sowing, and then weeding and fertilization should be carried out regularly during maintenance, and attention should be paid to preventing pests and diseases.

1. Soil preparation and fertilization

If you want to plant soybeans, it is most suitable to choose a plot with sufficient sunshine, deep soil, loose and fertile soil and convenient drainage and irrigation.

2. Sowing and planting

Select the appropriate variety of soybean grains, divide the plot, and then sow the soybean seeds into the soil according to a certain plant spacing, and cover with a thin layer of soil, if the soil is relatively dry, then the appropriate amount of watering is needed after planting, so that the soil is in a slightly moist state, so that the soybean seeds can germinate.

3. Maintenance management

After soybean planting, it needs to be weeded regularly, if the planting density is relatively high, it needs to be seedlings in time, in the soybean growth period, it needs to be regularly applied thin fertilizer to meet the nutrients it needs to grow, and in the rainy season, it needs to be drained in time, and it should be irrigated more in the dry season.

4. Prevention and control of diseases

In the process of soybean growth, if the environment is not suitable, it is prone to some diseases, which will lead to the healthy growth of soybeans, and the yield is easy to decline, so when planting, we can use fungicides to mix seeds first, and if there is a disease, it is necessary to spray it with a special drug.

<> soybean is suitable for planting in the plot with fertile soil, drainage and irrigation, and no pests and diseases, and the planting plot is leveled after turning 30 cm deep, and the crop residues, weeds and large stones are removed and then ridged or furrowed. Sowing is carried out after soaking and dressing, sowing soybeans in the open field are generally sown in summer, sowing in early soybean strip sowing, sowing in late soybeans in hole sowing, transplanting when the soybean seedlings grow to 4-5 cm, and the transplanting interval is 30-50 cm.

First, select the land and prepare the land.

Choose a plot with fertile soil, drainage and irrigation, and no pests and diseases to plant soybeans, and level the soil after turning it 30 cm deep. Pick out the residues of previous crops, weeds and large stones in the field to avoid the presence of pathogens that endanger the growth of soybeans. Then, according to your planting habits, you can decide whether to do ridge cultivation or furrow cultivation.

Second, soak seeds and mix seeds.

Soak the high-quality seeds in about 40 warm water, and the soaking time is 5-6 hours. Then use the agent to dress the seeds to eliminate the internal bacteria of the seeds, avoid the damage of underground pests, and improve the germination rate of seeds.

Three, sowing.

Early-maturing soybean varieties can be sown in strip sowing and late-maturing sowing in burrows. Soybean cultivation in the open field is generally sown in summer, that is, after the wheat is harvested, and it should not be sown too late, and the sowing should be completed before July at the latest, otherwise it will cause a reduction in soybean yield. When sowing, we should pay attention to controlling the sowing density, not too dense, to prevent mutual influence on growth, cover the soil with film after sowing, and water properly to improve the germination rate of seeds.

Wait until the seedlings grow to 4-5 cm, and the transplanting interval is 30-50 cm.

4. Field management

After transplanting for a week, the field is thinned or supplemented to ensure that the seedlings are complete, and then 5-7 days for a tillage weeding and fertilization, and at the same time to water once, this fertilization can be mixed with compound fertilizer and urea and applied. The second fertilization is to wait until the soybean blooms and sets pods, at this time the growth of soybeans needs a certain amount of nutrients, and at the same time, in order to make the pods full, you can apply a little potassium fertilizer and phosphate fertilizer. The most likely period for soybeans to have symptoms is when they bloom and set pods, so in order not to reduce the yield, soybeans need to be protected against flowers and pods, and dimethoate milk can be sprayed.

5. Harvesting

Most of the pods on the bean seedlings slowly turn yellow-green, and they can be harvested when they are hard and not flat or broken when touched by hand.
