Technical specification for high yield cultivation of soybean
Soybean is the main role of oil in our province. The development of soybean production is of great significance to improve the food composition of human father, the development of animal husbandry and crop rotation to improve soil fertility. From the actual situation of our province, soybean production mainly depends on increasing per unit yield to increase total yield. In order to achieve 200W per mu yield, it is not necessary to liberate soybean from the corn field, because the mixed cropping of soybean and corn is one of the reasons for soybean yield per unit area in our province, so it is necessary to clear the seed in Gongpian. Second, actively popularize and wait for sowing as the center to increase the application of agricultural fertilizer.

Cultivation and management techniques for high yield of soybean
Seed treatment. Generally take grain selection, remove small, miscellaneous, disease, worm pull, to achieve the same color of the navel. Do 1-2 germination tests before sowing, and the germination rate is more than 95%. Before sowing, 1-2 grams of ammonium molybdate per kilogram was used to dissolve the seeds in 30 grams of warm water, and then mixed with soybean rhizobium fertilizer, which accounted for 5% of the seed, and then sowed after low light and shade drying. Choose a place. Generally choose in corn, sorghum, millet and other stubble plots to avoid repeated and welcome stubble. Prepare the ground. Rake the ground in the middle of March

High yield of soybean must be controlled by ten hurdles.
First, according to the local climate, land fertility, soil properties, growth period, precipitation, effective accumulated temperature, production level, cultivation model and other factors, select high-oil and high-protein varieties with strong resistance and high yield. Second, we should close the soil preparation to soil tillage, adhere to the soil tillage system of the combination of loosening, turning, raking and rotation, and vigorously popularize the subsoiling tillage method, which is 40-50 cm deep, and the corn stubble for spring soil preparation should be pulped and ridged and suppressed in time to improve the quality of soil preparation and achieve clean soil without stubble.

"four taboos" for high yield of soybean
First, avoid continuous cropping, the yield will be reduced by 15% Mur20%, and the yield will be reduced by 20% Mur25%; second, the white seed field will cause diseases, insect pests and rodent pests, affecting the seedling emergence rate and yield; third, cross-regional planting should be in line with local conditions to meet the requirements of the technical indicators of accumulated temperature for varieties, otherwise, it will affect maturity and reduce yield. Four taboo root topdressing, soybean root nodule bacteria have nitrogen fixation, root topdressing nitrogen fertilizer, not only cause unnecessary waste, but also damage the fibrous root, resulting in reduced yield. Only in this way can we be sure of achieving high yield of soybeans.

What are the cultivation types of soybeans?
After long-term natural and artificial selection, soybean varieties adapted to different ecological types such as local growth period, climate characteristics, soil types and farming conditions were formed. According to the difference of sowing time and growth period, soybean can be divided into four cultivation types: spring soybean, summer soybean, autumn soybean and winter soybean.

Sowing technique of soybean by stages
Sowing by stages can stagger the corn harvest period of fresh soybeans, which is beneficial to prolong the supply period, expand market capacity, avoid a large number of centralized listing, resulting in excessive supply, large quantity and low price, and increase production without increasing income. and can ease the labor contradiction in the busy agricultural season to a certain extent. To do a good job of sowing by stages, the key is to achieve the following four points. 1, look at the local market situation to grow fresh soybeans and corn, high yield is not the goal, the important thing is high efficiency. & ldquo; goods are precious because they are scarce & the market price of rdquo;, is always the same as that of

What are the requirements for soil conditions of soybeans?
The growth and development of soybean is not strict to the soil, except swamp and saline-alkali land, the soil layer is deep, rich in organic matter, good drainage and irrigation, strong water retention, pH6.8-7.5 soil is the most suitable for planting soybean, red and yellow soil mountain planting soybean, as long as pay attention to fertilization management can also increase production.

Soybean can produce high yield by cutting root and picking heart.
The main results are as follows: 1. Soybean root-cutting and coring high-yield cultivation method of soybean direct seeding, row spacing 50 cm, coring 8 ~ 9 days after sowing, and root cutting on 10 ~ 11 days. When breaking the root, use a thin shovel to shovel off the main root at a depth of about 5 cm underground. The shovel is inserted obliquely and pulled out in situ to avoid shifting the bean seedling and injuring the lateral root. The position of the broken root should be about 2.5 cm under the stem of the bean seedling, too deep and too shallow can not achieve the desired purpose, or even cause dead seedlings. Second, several problems that should be paid attention to. 1. Density soybean density depends on variety and cultivation conditions.

Occurrence and control of soybean diamondback moth
The harmful symptom is that the larvae feed on the leaves, and the low instar larvae eat into mesh and notch shape. after the third instar, the larvae can eat all the bean leaves, so that the plant can not bear pods, which has a great impact on the yield. The occurrence regularity is the peak spawning period of adults from mid-late July to early August, the peak period of larval damage from late July to late August, and the yellowish mature larvae in early September to overwinter. Adults of living habits: adults go out day and night and have a strong tendency to black light. Start activities in the evening and fly

Cultivation techniques of narrow row and close planting of soybean
Shrinking ridges and increasing rows and narrow rows and close planting are one of the effective ways to increase soybean yield. The cultivation method is divided into three forms: first, large ridge and narrow row dense planting, which is a wide platform narrow row dense planting method which combines the original two ridges into one ridge or one semi-synthetic ridge. Its big ridge width is 97.5~140cm, sowing 4-6 rows on the ridge, and protecting 40-500000 seedlings per hectare. At present, 70cm ridge cultivation can generally increase the yield by about 20%. This cultivation technique is suitable for low waterlogging areas in the south and east of China with high productivity.
