High-yielding cultivation techniques for spring soybean
Soybean cultivation is a highly effective method for farmers to improve soil fertility, enhance field productivity, and achieve high returns in a short growing period. It's an excellent strategy for increasing income and promoting agricultural development. Here are some advanced techniques for spring soybean high-yield farming.
First, seed treatment plays a crucial role in ensuring strong germination and healthy plant growth. Before sowing, select high-quality seeds and expose them to sunlight for 3 to 4 hours to boost their vitality. Then, apply a seed coating using either 0.1% to 0.2% ammonium molybdate or rhizobia (mix 0.5 kg of the bacteria with 10 kg of seeds). This helps promote early and abundant nodulation, leading to better branching, higher pod setting rates, and increased yields by 10% to 20%.
Second, prepare the soil thoroughly. Plow the field to a depth of 20 to 25 cm, and level it properly. For paddy fields, create raised beds of about 12 meters wide to prevent waterlogging. Apply a base fertilizer consisting of 1,500 kg of compost, 600 kg of ash, 10 kg of phosphate fertilizer, and 20 kg of compound fertilizer per 667 square meters. Mix everything well before sowing. Plant seeds at a spacing of 16–18 cm between rows and 12–14 cm within rows, placing 1–2 seeds per hole. Aim for 28,000 to 30,000 plants per 667 square meters.
Third, choose suitable varieties based on the soil type. Using autumn soybeans from the previous year as seed can improve germination, ensure uniform emergence, and lead to earlier maturity and higher yield. For paddy fields, varieties like "Gudou 1" and "Gudou 2" are ideal. On red soil hills, "Maohuanghuang," "Dajinhuang," and "Yuedou No.1" are recommended. These improved varieties are compact, drought-tolerant, and easy to manage, making them perfect for high yields.
Fourth, implement early weeding and fertilization. When seedlings reach 15–20 cm in height, perform shallow cultivation to encourage rhizobial activity and feed nutrients to the cotyledon nodes. Apply lime powder at 50–60 kg per 667 square meters to improve pest resistance and reduce lodging. During the branching stage, combine weeding with 5 kg of urea and 7 kg of potassium chloride per 667 square meters to increase the number of productive branches and flowering rate. Spray 0.7 grams of paclobutrazol in 25 kg of water during the podding stage to promote node formation. During flowering, spray potassium dihydrogen phosphate 1–2 times to boost seed set by over 20%.
Fifth, practice topping to maximize yield. At flowering time, spray 4–5 grams of sodium sulfite in 50 kg of water once a week for 2–3 applications. This enhances photosynthesis and increases yield by 8% to 10%. About 20 days before harvest, remove the top of the plant to improve pod scarring and increase yield by 7% to 8%.
Lastly, focus on pest and disease control. In the early growth stage, monitor and manage locusts, ground beetles, and stem borers. During the reproductive phase, pay special attention to soybean aphids, ladybugs, and leaf spot diseases. Timely intervention ensures healthier plants and better yields.
By following these techniques, farmers can significantly improve their soybean production, making it a sustainable and profitable crop choice.
