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.

Causes and Control Methods of Deformed Mushrooms in Greenhouses
1. Hollow white-stem mushrooms. The mushroom stems become loose and white, and in severe cases shrink to form a hollow center. Causes: during the fruiting body growth stage, it is caused by dry air and high temperatures. When the relative air humidity is below 85%, the water content of the casing soil layer is relatively low, and the temperature inside the mushroom house is above 18°C, the mushrooms grow quickly and evaporate water quickly, causing the water absorbed by the mushroom body to be less than the water lost through transpiration. Control methods: spray water promptly during the day to keep the relative air humidity at 90%, and ventilate promptly after spraying water in the morning and evening to lower the greenhouse temperature, keeping it at 14-

Key Management Points for Greenhouse Potatoes During the Tuber Formation Stage
1. Disease control. Spray in the field at the early stage of disease onset, using 75% thiophanate-methyl at 600-800 times dilution, or 40% carbendazim at 400-600 times dilution, or 600 times dilution of anthracnose fumei, to control anthracnose, powdery mildew, late blight, etc.; use 72% agricultural streptomycin at 20 grams per mu (667 sq m), or 25% qingkuling wettable powder, to control bacterial scab: use 72% puleike aqueous solution, or 30% eduling aqueous solution at 800 times dilution, or 70% mancozeb wettable powder at 500 times dilution, to control fusarium wilt and gray mold; use 20%

Application Methods of Fertilizer Long in Formula Fertilization for Rice
1. Advantages of Fertilizer Long: (1) Long-acting and synergistic effect, extending the fertilizer efficiency period of nitrogen fertilizer by 1 time, with no fertilizer deficiency phenomenon throughout the entire growth period of rice. (2) Improved nitrogen fertilizer utilization rate; deep fertilization overcomes fertilizer loss due to running, overflowing and seepage of field water, reducing fertilizer loss. (3) Enhanced resistance of rice to low temperature, drought and disease erosion. (4) Changes traditional multiple surface fertilization to deep one-time fertilization, saving fertilization labor and costs. (5) Reduced nitrogen fertilizer dosage; according to plots with different fertility, the pure nutrient amount of nitrogen fertilizer can be reduced by 15%-25%. 2. Fertilizer Long

How to treat postpartum paralysis in pigs and sheep? This effective formula works well
1. Treating postpartum paralysis in sows. Postpartum paralysis in sows mostly occurs within 2-5 days after farrowing. In the early stage of the disease, the animal is listless, has reduced appetite, and produces less milk; body temperature is normal or slightly elevated. In mild cases, standing is difficult and the hindquarters sway; in typical cases, the animal cannot stand and lies down in a stupor. For treatment, add 4% bone meal, AD3 powder and trace element additives to the feed. Inject the sick pig intramuscularly with 3-5 milliliters of vitamin D3 colloidal calcium, 5-10 milliliters of vitamin E injection (twice daily); vitamin D3 600-1200 international units, once daily, or take an appropriate amount of quicklime, add clean water, stir and let stand. Each time the affected sow is fed, take 300-400 milliliters of the clear supernatant limewater and mix it into the feed. Generally, feeding continuously for 10 days gives a marked curative effect.

Cotton planting method reform should be combined with autumn sowing production
In recent years, to promote high cotton yields, the Ministry of Agriculture of the People's Republic of China has carried out a 10,000-mu high-yield cotton creation activity in the major cotton-producing provinces nationwide. Recently I inspected high-yield cotton fields in Hubei, Anhui, Jiangsu, Jiangxi and other provinces, and previously also conducted surveys in high-yield cotton fields in Hunan and Zhejiang provinces. The high-yield cotton creation goals are broadly the same across regions, but the planting patterns are not entirely the same, and the planting methods each have their own particularities. Cotton yield is composed of indicators such as planting density, number of bolls per plant, boll weight and lint percentage, among which planting density is closely related to cotton yield, and planting density
