Why soybean root cutting and pinching can increase yield
1. High-yield cultivation method for soybean by root cutting and pinching: Direct sow soybeans with a row spacing of 50 cm. On the 8th to 9th day after sowing, carry out pinching; on the 10th to 11th day, carry out root cutting. When cutting roots, use a thin iron shovel to cut the main root at a depth of about 5 cm below the soybean seedling. Insert the shovel at an angle and pull it out from the same position to avoid displacing the soybean seedling and damaging the lateral roots. The root cutting position should be controlled at about 2.5 cm below the soybean seedling stem. Too deep or too shallow will fail to achieve the expected purpose and may even cause seedling death. 2. Several issues to note 1. Density: Soybean density should be determined according to the variety and cultivation conditions,

What are the soil requirements for growing soybeans?
Soybeans are not strict about soil conditions for their growth and development. Apart from swampy land and saline-alkali land, the most suitable soil for growing soybeans is deep, rich in organic matter, well drained and irrigated, with strong water-holding capacity and a pH of 6.8-7.5. As for growing soybeans on red and yellow soil in mountainous areas, as long as attention is paid to fertilizer management, increased yields can also be achieved.

Detailed Explanation of Key Techniques for Staged Sowing of Soybeans
Staged sowing can stagger the harvest period of fresh soybeans from that of corn, which helps extend the supply period, expand market capacity, and avoid the phenomenon of excessive supply caused by large-scale concentrated market entry, where large volume leads to low prices and increased production without increased income. It can also alleviate the labor conflict during the busy farming season to a certain extent. To do a good job in staged sowing, the key is to achieve the following four points. 1. Observe local market conditions. When growing fresh soybeans and corn, high yield is not the goal; high efficiency is what matters. "Rare things are precious," and market prices are always inversely proportional to

What are the cultivation types of soybean?
Through long-term natural and artificial selection, soybean has developed into various varieties adapted to different ecological types such as local growth periods, climatic characteristics, soil categories, and cultivation conditions. According to differences in sowing time and growth period, soybean can be divided into 4 cultivation types: spring soybean, summer soybean, autumn soybean, and winter soybean.

For high soybean yields, keep these four taboos in mind when planting
First, avoid continuous cropping and alternating cropping. Continuous cropping can reduce yields by 15%-20%, and alternating cropping can reduce yields by 20%-25%. Second, avoid sowing untreated seed. Sowing untreated seed can cause disease, insect pests and rodent damage, affecting emergence rate and yield. Third, avoid planting across regions. Adjust measures to local conditions and meet the requirements of the accumulated temperature technical indicators needed by the variety; otherwise, it will affect maturity and cause yield reduction. Fourth, avoid applying fertilizer at the roots. The rhizobia at the soybean roots have a nitrogen-fixing effect. Applying nitrogen fertilizer at the roots not only causes unnecessary waste, but also damages the fibrous roots and causes yield reduction. Only in this way can high soybean yields be achieved with confidence.

Ten key steps for high-yield soybean cultivation
First, the good-seed step. According to local factors such as climate, soil fertility, soil properties, growth period, rainfall, effective accumulated temperature, production level, and cultivation mode, choose high-oil and high-protein improved varieties with strong stress resistance and good yield performance. Second, the land-preparation step. In soil tillage, adhere to a soil tillage system combining subsoiling, plowing, harrowing, and rotary tillage, with subsoiling as the main practice; vigorously promote the subsoiling method, with a subsoiling depth of 40-50 cm. For spring land preparation on corn stubble, ridge up along the thawed soil and press in time to improve land-preparation quality, achieving clean ground with no stubble,

Key Cultivation and Management Techniques for High-Yield Soybeans
Seed treatment. Generally, seed selection by hand is adopted, removing small, mixed, diseased, and insect-damaged seeds to achieve uniform hilum color. Before sowing, conduct 1-2 germination tests; a germination rate above 95% qualifies the seeds for planting. Before sowing, for each kilogram of seed, use 1-2 grams of ammonium molybdate dissolved in 30 grams of warm water and mix into the seed; after drying in the shade, mix in soybean rhizobium fertilizer at 5% of the seed weight; after drying in weak light, the seeds can be sown, mixing and using as you go. Field selection. Generally choose plots following corn, sorghum, millet, and similar crops, avoiding continuous cropping and adjacent cropping. Land preparation. Harrow the land in mid-March.

Detailed Explanation of High-Yield Soybean Cultivation Technical Specifications
Soybean is a major oil crop in our province. Developing soybean production is of great significance for improving people's food composition, developing animal husbandry, and improving soil fertility through crop rotation. From the actual situation of our province, soybean production mainly relies on increasing per-unit yield to increase total output. To achieve the target of over 200 kg per mu, it is necessary to liberate soybean from corn fields, because intercropping and mixed cropping of soybean with corn is one of the reasons for the low per-unit yield of soybean in our province, so clean planting of entire fields should be promoted; second, actively promote high-yield cultivation techniques centered on equidistant sowing, with increased application of farmyard manure

How to Grow Soybeans for High Yield? Detailed Explanation of Key Cultivation Techniques
1. Crop rotation selection: Choose level, low-lying land with good drainage, where the previous crop received adequate fertilizer and the soil is fertile - wheat, corn, potatoes, and melon or vegetable plots are best. Do not plant after continuous cropping or after sunflowers; compared with proper rotation, yield will decrease by 21.3%. 2. Land preparation and fertilization: Autumn plowing, land preparation, and fertilization are best, as this helps preserve soil moisture and freeze insect eggs to death. If preparing land in spring, it must be done during the thawing period. When preparing the land, according to soil fertility, generally apply more than 2 cubic meters of high-quality farmyard manure per mu, 10Kg of diammonium phosphate, and 5Kg of potassium sulfate, mix evenly, and apply before ridging as base fertilizer. 3. Seed dressing with chemicals: To control underground pests, you can use

What are the benefits of feeding rabbits soybean cake water?
Chop the soybean cake into small pieces, add water and boil it, filter out the residue, and add 1% salt to the filtrate for the rabbits to drink. After bucks drink soybean cake water, their coat and body condition improve, and mating at this time can increase the conception rate of does. After nursing does drink soybean cake water, milk secretion can increase by 28%. After young rabbits drink soybean cake water, they grow vigorously, and their weight at weaning can reach 650-750 grams, a 22.5% greater weight gain than those given plain water.
