Elaborate on soybean cultivation and yield increase technology? How to improve the quality of soybea

Increase the application of organic fertilizer: organic fertilizer has comprehensive nutrition, slow decomposition, and long-lasting fertilizer effect, which can fully meet the nutrient demand of soybean throughout the growth period, especially in the later growth period, and is the basis for high soybean yield. Pay attention to the selection of disease-resistant varieties.

Disease-resistant varieties should be selected according to the occurrence of local diseases. Virus disease and downy mildew occur seriously in our province, and high-yield, high-quality, and disease-resistant varieties should be selected according to the actual situation of each place.

The selection of varieties should be based on the actual situation of each place, which can not only make full use of the growing season, but also ensure high and stable yield. Yellow pods should be achieved in years with the fewest local frost-free periods. Our province should choose soybean varieties that are about 115-125 days old.

Soybeans are more sensitive to soil. Field preparation is an important factor affecting soybean yield. Before sowing, the soil should be scientifically optimized under the premise of analyzing the growth habit of soybean, deep ploughing and fine harrowing, and fine land preparation.

According to the requirements of soybean planting, too shallow soil preparation depth is not conducive to the root growth of soybean seedlings, which may lead to lodging, while too deep will make the soybean root grow too vigorously, thereby reducing soybean yield. Second, debris should be removed from the soil as much as possible. and should maintain the permeability of the soil.

Such carefully cultivated fields are conducive to the healthy germination of soybeans and ensure reasonable economic benefits.

Soybean varieties with weak stems are prone to lodging, and soybean varieties with strong stems have too much fat and water, and the density is too large. Under the high-yield cultivation level, semi-dwarf varieties with high stem strength and high yield potential should be selected, combined with formula fertilization, and reasonable dense planting.

Fertilization method, apply more than 2 tons of well-rotted human and animal manure per mu in autumn, and evenly apply it to the field. When the tractor turns deeper, the fertilizer will turn deeper, leveled and raked finely.

The establishment of a scientific and high-quality field management system is an important measure to ensure the yield of soybean planting. It mainly includes soybean crushing and compaction, seedling management, flowering management and top dressing. When the seedling period should do a good job of checking the seedlings and supplementing the seedlings, on the bean seedlings, it is necessary to check the seedlings in a timely manner, if you want to replenish the seedlings, it is best to choose transplanting after four o'clock in the afternoon.

Seedling thinning should be carried out under the condition of ensuring the stable growth of soybean seedlings. After the seedlings are set, weeds should be removed according to the actual situation in the field to protect the nutrition of soybean seedlings and maintain the air permeability of the root soil, generally three to four times.

The management of soybean seedlings is very important, to ensure that the seedlings are strong and strong, is the basis of high soybean yield, the following four management measures are very important, the specific content together:

1. Check the seedlings. After soybean emergence, it is necessary to observe the emergence of seedlings to see whether the whole seedlings are full, if the sowing amount is too large, and there are too many seedlings when the seedlings emerge, it is necessary to carry out the seedling operation, and the overly dense seedlings are manually pulled out, so as to ensure the ventilation and light transmittance of the field in the middle and late stages, and at the same time can reduce the competition between seedlings.

If the seedlings are not good, there is a lack of seedlings and broken ridges, it is necessary to replant in time, pay attention to replanting, do not plant dry seeds directly, and then replant after germination, so as to ensure the number of seedlings in the field.

2. Cultivating. <>

Soybean seedling stage of tillage, one is to loosen the soil, increase the permeability of the soil, improve the ability to retain water and fertilizer, conducive to the growth of soybeans, the second is to promote the growth of the root system, so that the root system is deeper and more, not easy to lodging in the later stage, and the third is in the process of tillage, but also to remove a part of the weeds.

However, the operation of cultivating, individual farmers with small planting area may go to implement more, if it is a large farmer, due to too much workload, labor costs are too high, will not be implemented, everyone according to their own situation.

3. Weeding. The seedling stage is the best period for weeding, and herbicides are generally sprayed when weeds have 2-4 leaves, and the weeding effect is good.

There are many weeds in soybean fields, such as common sharp-leaved grasses: barnyard grass, dogtail grass, horsetail, cow tendon grass, Qianjinzi, etc.;

Broad-leaved grass: quinoa, purslane, iron amaranth, Xanthium, hemp, etc.;

In addition, there are perennial weeds: horsetail, spiny cabbage, field spines, reeds, etc.

According to the different grass directions in the field and the resistance of local weeds, the herbicides are reasonably selected, such as the herbicides of sharp-leaved weeds can be used with quinoxalin, olethoxone, pyridoxafen, etc., and the herbicides of broad-leaved weeds can be used with ethylcarboxfluorfen, herbicide, trifluorocarboxyfen, etc., and sulfafen and imidazole ethylnicotinic acid can be mixed with the above agents.

4. Pest control.

Soybean seedlings will be harmed by some pests and diseases, such as underground pests, aphids, cotton bollworms, root rot, soybean cyst nematode disease, etc., some can be prevented by pre-sowing seed dressing, and some need to be sprayed after seedlings for control

When selecting soybean varieties, many factors such as climate, rainwater conditions, and soil fertility should be considered in the planting area. And pay attention to prevent cross-area planting.

Soybeans are crops that use land and raise land. As the front stubble of cereals, it can increase the yield of the back stubble to varying degrees.

Drying seeds can effectively improve the germination rate, generally 2 3 days in advance of the seedlings, during the drying period should follow the principle of spreading thin and diligent turning, if the weather is too hot, then should do a good job of sunscreen treatment, in order to prevent the seed coat from being infected by germs.

In low temperatures or dry weather, seeds germinate in the soil for a longer time and are susceptible to pests and diseases, so soybean seed coatings are used.

If you want to improve the quality of soybeans and increase the yield of soybeans, you must first breed good varieties. It is very important to choose the soybean variety according to local conditions. Secondly, we must do a good job in field management.

Choosing better seeds and preventing insect infestations can increase yields. Keeping the soil moist, using organic fertilizers appropriately, and ensuring adequate sunlight can improve the quality of soybeans.

Spray 200 times liquid high-lipid film enhancer (emulsion) once in 20 days, which can reduce the use of chemical fertilizers and pesticides by half. The main nutritional indicators of soybean testing will be improved.

First of all, after soybean flowering, it is necessary to begin to absorb nutrients, at this time, cultivating soil can prevent plant lodging, generally in soybean flowering and ridge sealing before cultivating, to maintain field permeability, promote root development, increase lateral roots, improve soybean lodging resistance, to achieve the purpose of increasing yield. Secondly, during the important period of soybean flowering period, the leaves of the plant are normal in the morning, and when the leaves wilt at noon, it is necessary to irrigate in time, generally at night. It is best to use sprinkler irrigation, with a volume of 30 to 40 mm per irrigation.

If there is too much water in the field, soybeans can not grow normally, after heavy rain, it is necessary to remove the water in the field in time, reduce soil moisture and air humidity, and promote the normal growth of plants. Finally, soybean needs a lot of fertilizer nutrients during the flowering period, and if it is not topdressed in time, there will be fewer flower pods, flower and pods, and weak plants. 3 5 kg of urea, 5 10 kg of superphosphate can be applied per mu, and potassium sulfate can also be used, with a dosage of about 5 kg per mu.

When fertilizing the last time, the fertilizer is evenly applied to one side of the bean plant, and the top dressing should not touch the leaves, nor close to the roots, and then cover the soil.

The flowering period of soybean is the period of soybean reproductive growth and vegetative growth at the same time, while flowering and podding, while the plant grows, in the rainy and windy area, in the soybean into the flowering period, before the ridge is sealed, the soybean should be cultivated and the ridge is supported, the benefits of the ridge are obvious, the drought weather is easy to water along the ditch, in case of heavy rain, drain along the ditch. After ridge support, it is also conducive to the increase of root lateral roots, laying the foundation for high soybean yield, controlling the height of soybean plants, and improving the lodging resistance of soybean. After soybean enters the flowering period, the metabolism is vigorous, the water required increases, and the lack of water encounters drought, which is easy to cause the increase of soybean flower drop, therefore, in order to prevent the physiological water shortage of soybean and encounter dry weather, timely replenishment of water for soybean is an important measure to improve the high yield of soybean.

Generally, the soybean is properly sprinkled with irrigation, or watered with small water, it is strictly forbidden to flood the soybean with large water, which affects the normal respiration of the soybean root system, if it encounters heavy rain, resulting in excessive soil moisture, it is necessary to drain the water in time, and try to create a good soil environment for the soybean root system.

The soil must be very fertile, the pH should be suitable, the temperature should be suitable, the seeds should be very high-quality, watered more, eat more fertilizer, and have a certain daily life, so as to achieve high yield.

Soybean is an annual herbaceous plant, 30-90 cm tall, with thick, erect stems and a dense brown long mane. The pods are plump, slightly curved, drooping, yellowish-green, densely covered with long brownish-yellow hairs. The flowering period is 6 July, and the fruiting period is 7 September.

Its seeds are rich in vegetable protein and unsaturated fatty acids, and have high food, industrial and pharmaceutical value. So, what are the planting techniques to increase soybean yields? Next, let's check it out!

Fertilization method. Increase the application of organic fertilizer and avoid long-term continuous cropping. Organic fertilizer contains a more comprehensive nutrient composition and rich organic matter, which is the basis for high yield of soybean.

The application of decomposed organic fertilizer in the soil can make soybean play an irreplaceable role in production and reduce the adverse effects of continuous cropping. It is also indispensable to avoid the use of nitrogen fertilizers in large quantities, as phosphorus and potassium fertilizers are not as large as nitrogen fertilizers. 2000 kg of fully decomposed organic fertilizer, 40 kg of 45% controlled-release fertilizer, and 2 kg of a variety of trace elements were applied per mu.

The right place.

To catch up with the maturity of wheat soybeans, it is easier to ripen early than late. If it is too late, the accumulated temperature and light are not enough, and the yield is not good. Larger soybean varieties can keep about 10,000 seedlings per mu, and smaller soybean varieties can protect 2-30,000 seedlings per mu.

Control water use in a timely manner.

In summer, soybeans are dry and flooded. When the leaves of soybeans appear to be roasted like fire at noon, they should be watered immediately in the evening or early morning, and the amount of water should not be too large. The most critical period for soybean water requirement is from flowering to grain filling.

The soil moisture content is controlled at about 75% to minimize the reduction of soybean yield by water. When the field is waterlogged due to heavy rain in summer, it should be drained in time to prevent waterlogging.

Supplemental foliar fertilizer.

Soybean was sprayed with potassium dihydrogen phosphate + borax + ammonium molybdate + brassinolide from flowering to grain filling stage. Spray every 7-10 days, 2-3 times in a row.

Soybeans control vigorous growth. To control the vigorous growth of soybean, the relationship between reproductive growth and vegetative growth can be adjusted by adjusting the moisture content, and the overdense plants can be artificially removed to improve the ventilation and light transmission performance. Spraying plant growth regulators can achieve the purpose of flowering and pod-setting.

On vigorously growing soybean leaves, chloroquine can be sprayed. The first spray can be sprayed with 50 kg of chloroquine diluted into a solution when spraying 4 soybean compound leaves on one acre. The second spray was at the beginning of soybean flowering, diluted with 50 kg of liquid and sprayed on one acre of land.

Timely control of soybean pests and diseases.

The summer drought is conducive to the development of soybean spider mites and aphids. If the soil moisture is too high, the soybean will develop root rot. It should be observed that it is strictly observed.

In the early stage of the occurrence of pests and diseases, spray evenly with MTAP 1000 times and imidacloprid 1500 times + methylthiazide 800 times.

To sum up, if farmers want to increase soybean yields, they should pay more attention to scientific planting techniques and fine management of plants.

We must choose good varieties, mix pesticides in the seeds, we must choose relatively fertile land, pay attention to the density of planting, and apply appropriate acacia in Sun Chun to only tolerate fertilizer.

If you want to effectively promote the high yield of soybeans, you must choose loose and fertile soil, but also choose high-quality varieties, sowing as much as possible, and return to the rock to grasp the season of phase leakage and leakage, spray some fertilizer appropriately, and do a good job in the prevention and control of pests and diseases.

Choose a good variety of soybeans, pay attention to fertilization, pay attention to the drainage of the land, in order to improve the yield, pay attention to fertilization.
