Key Techniques for Mechanized High-Yield Cultivation of Densely Planted Soybean
The integrated mechanized high-yield cultivation technique for densely planted soybean is based on the three-ridge soybean cultivation technique, while continuing to maintain deep loosening, layered deep fertilization, and precision sowing. It draws on foreign experience in narrow-row dense planting and semi-dwarf varieties for increasing yields, and combines these with matching machinery to form an integrated mechanized high-yield cultivation technique, including flat-planting dense planting technology and small-ridge dense planting technology. I. Technical advantages 1. Reasonable dense planting increases yield. The technical feature is reasonable dense planting, uniform crop distribution, and increased crop photosynthesis. Select lodging-resistant semi-dwarf varieties, increase

High-yield Cultivation Techniques for Soybean with Wide Ridge and Narrow Row Close Planting
Wide ridge and narrow row close planting of soybean can increase the canopy leaf area index, make full use of light energy, and achieve the goal of increasing yield. (1) Site selection and land preparation. The best preceding crops are wheat, corn or potato. Ridging is done as sowing proceeds. The ridge spacing is 130 cm, the ridge height is 25 cm, and the ridge top width is 3O cm. (2) Variety selection. For wide ridge and narrow row close planting of soybean, the varieties selected should generally be 168, ZOQI, 9409B, Fengshou 544, Mijiawang, Hefeng 25, Hebing 93-BS, etc. Seed selection should be carried out before sowing.

Detailed Explanation of Uniform Planting High-Yield Cultivation Techniques for Soybean
1. Determine planting density, row spacing and plant spacing according to the plant-type traits, branching and other characteristics of the variety. ① For dwarf, early-maturing, main-stem-type varieties that resist [unclear] branching: row spacing 30-40 cm, plant spacing 8-10 cm, seedling retention density 18,000-25,000 plants. 2. Determine planting density based on soil fertility level and management level. After determining the planting row spacing according to the variety, density should also be adjusted according to soil fertility conditions and water and fertilizer management level. 3. Sow early with sufficient soil moisture. Early sowing can significantly increase yield and increase fat content, generally sowing on June 10-20.

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,

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

Mengshan Red Four-Season Honeysuckle: excellent variety with high yield
1. The flower bud color is rich in variation. Before blooming, it changes from purplish red to bright red; when blooming, it turns pink; after blooming, it becomes a mix of red, yellow and white, very beautiful. Its fragrance is stronger than ordinary honeysuckle, and its medicinal potency is high. The flowers, leaves and stems can all be used as medicine, for treating painful swellings, boils and sores, externally contracted cold, and the early stage of seasonal febrile disease, clearing heat and detoxifying. 2. It blooms early. It blooms 5-10 days earlier than ordinary honeysuckle, with the flowering period from mid-May to mid-October, about 150 days. It can bloom 4 times a year.
