Detailed Explanation of Key Techniques for Uniform Planting and High-Yield Cultivation of Soybeans
1. Determine planting density, row spacing and plant spacing according to varietal plant-type traits, branching and other characteristics. (1) Short-stalked, early-maturing, main-stem-type varieties resistant to lodging and branching: row spacing 30-40 cm, plant spacing 8-10 cm, retained seedling density 18,000-25,000 plants. 2. Determine planting density according to soil fertility level and management level at the plant spacing. After determining the planting row spacing according to the variety, density adjustment should also be made according to soil fertility conditions and water-fertilizer management level. 3. Sufficient soil moisture and early sowing. Early sowing can significantly increase yield and increase fat content

Recently, many farmer friends have called to ask how Nongwang Nano Magnetic Energy Liquid should be sprayed. Here is a brief introduction: 1. Foliar spraying: What does Nongwang Nano Magnetic Energy Liquid do? Nano Magnetic Energy Liquid is a non-chemical product, a magnetic liquid prepared using the method of magnetic drug bioengineering.

Key Technical Points for Field Management of Soybeans in the Mid-to-Late Growth Stages
I. Management During the Flowering and Podding Stage During the flowering and podding stage, the main management tasks are to strive for more flowers, early flowers, uniform flowers, increased flowers, and increased pods, and to prevent flower and pod drop. Management should be based on observing the plants, combining preservation and control; for high-yield fields, control should be the main approach, avoiding premature canopy closure and shading, so that maximum leaf area is reached at the end of flowering. Specific measures: continue hoeing weeds before canopy closure, and apply irrigation and fertilizer as appropriate based on plant condition; at the early flowering stage, fertilizer should be applied to weak plants, but not to vigorous plants to prevent excessive vegetative growth. Applying phosphate fertilizer during the flowering and podding stage has an obvious effect; during this period, soybean leaf area reaches its maximum, water consumption increases, and both transpiration intensity and water demand

Key Integrated Management Techniques for Soybeans During the Flowering and Podding Stage
When soybeans enter the flowering and podding stage, vegetative growth and reproductive growth proceed together, requiring sufficient water, nutrients and light. In terms of cultivation measures, vegetative growth and reproductive growth should be coordinated to achieve many pods and many seeds. The main measures should include the following "three preventions" and strengthened management during the seed-filling and maturation stage. The "three preventions" measures during the flowering and podding stage (1) Preventing excessive vegetative growth: when soybeans have shown 2 tillers and are flowering, use 30 grams of 15% paclobutrazol wettable powder per mu, mix with 40 kg of water, and spray to top the plants, which can shorten internodes, control top vine growth, increase flowers and preserve pods, so that pods cover the top; (2) Preventing drought and waterlogging: during the soybean flowering period, attention should be paid to summer drought, seepage and moisture retention, and in case of severe waterlogging, drain promptly to reduce waterlogging damage; (3) Controlling pests: from the end of July to mid-August is the peak outbreak period for soybean semi-looper, bean hawk moth, leaf roller, alfalfa noctuid and other pests. Pesticides with contact and stomach poison effects such as fenvalerate or cypermethrin plus dimethoate emulsion or dichlorvos can be used for control, eliminating pests at the 1st-2nd instar stage.

What causes yellow leaves in soybeans before flowering
In recent years, yellow leaf disease has occurred rather widely on soybeans and other legume crops. If not controlled in time, it can cause serious harm to crop growth. For example, when it occurs early, the leaves turn yellow, the plants are short and stunted, and no pods form. When it occurs at the mid stage, even if pods form, they contain no seeds, and even if there are seeds, they are shriveled, causing severe yield loss or total crop failure. The causes are as follows: First, long-term application of chemical fertilizers and reduced use of farmyard manure have caused soil compaction. Second, in recent years, the use of combine harvesters for harvesting wheat and the widespread practice of burning wheat stubble have destroyed the surface structure of the soil. Third, nutrient deficiency

What are the key technical points for flat-planting narrow-row dense planting of soybeans?
Key technical points for flat-planting narrow-row dense planting of soybeans: 1. Seed and treatment: For variety selection, choose suitable varieties according to the local ecological type and local conditions. 2. Seed quality: It must reach Grade II improved seed or above under the seed grading standard. 3. Seed treatment: Use seed coating agent for seed dressing, selected according to the types of pests and diseases and soil conditions. 4. Rotation and tillage land preparation: For crop rotation, use a rotation of more than 3 years, do not plant continuously or on adjacent stubble, and the previous crop should mainly be wheat-type crops. For tillage, adopt mainly deep loosening, combining loosening and harrowing, to facilitate drought resistance and moisture conservation. 5

How should soybeans be harvested properly? A full breakdown of the key methods
Soybeans should be harvested promptly once mature. If harvesting is too late, the pods lose too much moisture and are prone to shattering and dropping seeds, causing losses. The suitable harvest period should be determined according to different harvest methods. When harvesting with a sickle, begin harvesting after all soybean leaves have fallen, as nutrient transport to the seeds has essentially stopped by then. Mechanical harvesting must be done after the whole plant is fully mature and dry. Manual harvesting is best done in the morning, when the soybean plants have a higher moisture content, so they do not prick the hands and are less prone to pod shattering. A low stubble height is required, with no "horse ears" left exposed and no missed cutting.

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

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.
