The technology is expected to cover a total area of 600 million mu within the province. With an average yield of 160 kilograms per mu, high-yield fields can reach up to 200 kilograms, while mass production areas can achieve 250 kilograms per mu. This method increases efficiency by 60 yuan per mu. This technique is suitable for promotion in the province’s rice-growing regions, particularly where conditions are favorable for rapeseed cultivation. Key technical points include: First, carefully select improved varieties. Based on the main rapeseed varieties recommended by the Provincial Department of Agriculture, choose hybrid varieties that are high-quality, disease-resistant, have a moderate growth period, and offer good seed quality and high yield. In Sanxian District, it is ideal to use double-low rapeseed varieties with an early growth cycle and late sowing. Second, prepare the field properly. After harvesting the previous rice crop, ensure the remaining stubble is less than 5 inches tall. Use a rope to mark the ditches, making the ridges 120 cm wide, the ditches 30 cm wide, and 20 cm deep. Slightly widen and deepen the central furrow and drainage channels to match the three-ditch system. Use a ditching machine to create the ditches, and evenly spread the soil back onto the ridges. Any uneven areas should be manually flattened. Third, apply fertilizers scientifically. Use phosphorus, potassium, and boron as base fertilizers, and apply nitrogen fertilizer in a ratio of 5:3:2. For medium-fertility fields, apply 40 kg of rapeseed formula and 1 kg of borax or 200 g of boron as base fertilizer. Before and after the winter solstice, apply about 10 kg of compound fertilizer, adding 2–3 kg of urea if needed. After the spring budding stage, apply 3–5 kg of urea and spray 50 g of Sorbor Boron. One week after flowering, apply 1 kg of potassium dihydrogen phosphate or foliar fertilizer to promote pod development. Fourth, plant at the right time. The best sowing period is mid to late September through mid to late October, though it can be adjusted to early September or as late as the end of October. Sow at a rate of 200–300 grams per mu, adjusting based on fertility and timing. When plants have five leaves, transplant them. Remove any uneven or weak seedlings for use as feed. Transplanting should begin in early October and continue until mid-November. Fifth, maintain proper planting density. At the third-leaf stage, remove weak or overcrowded seedlings. At the fifth-leaf stage, perform thinning. Adjust density based on land quality—8,000–10,000 plants per mu (12–15 per square meter) for fertile land, 10,000–12,000 plants for poorer or later-planted fields (15–18 per square meter), and up to 15,000–20,000 plants for special plots (22–28 per square meter). Generally, aim for 6,000–8,000 plants per mu (10–12 per square meter), adjusting for early or late planting. Sixth, implement chemical weeding. Apply herbicides 5–7 days before site preparation, targeting broad-leaved weeds in sunny afternoons, and apply within 24 hours. Once seedlings reach the three-leaf stage, spray herbicides to control emerging weeds. Seventh, monitor and manage pests. During the seedling stage, focus on controlling cabbage caterpillars and aphids. Follow pest forecasts and act promptly. During flowering, apply 40% sclerotinia fungicide in early flowering, spraying from the bottom up to ensure coverage. Monitor conditions and reapply as needed. Eighth, harvest and sell timely. Begin harvesting when over 80% of the plants show pod color, but before the upper pods fully yellow. After stacking or spreading for 5–7 days, thresh and dry the seeds promptly. Encourage mechanical harvesting, and delay the final harvest by 5–7 days for one-time collection. Stay informed about market trends to avoid long-term storage, which can damage quality and affect sales timing.
