1. Soil Preparation and Fertilization: Select fields with sandy loam or loamy soil that is loose, well-aerated, and moderately fertile. Apply fertilizers at the end of May or early June. Use 10-15 kg of urea or 20-25 kg of ammonium bicarbonate per mu, along with 5-10 kg of potassium chloride to ensure balanced nutrition for the crop. 2. Seed Treatment: Soak seeds 1-2 days before sowing to enhance germination and protect against diseases. To prevent sesame black spot and stem blight, soak the seeds in warm water (50-55°C) for 15 minutes, then cool them down and air dry before planting. Plant approximately 0.5 kg of seeds per mu. 3. Seedling Thinning and Spacing: Once the seedlings have developed 2-3 pairs of true leaves, transplant them with a spacing of 15-20 cm between plants. Thin out weak seedlings and keep only 8,000 to 10,000 healthy ones per mu to promote better growth and yield. 4. Timely Pinching: After the initial flowering period, typically within 10-20 days, pinch off the main stem and the top portion of each branch by about 1 cm. This encourages more branching and improves overall plant structure and productivity. 5. Disease Prevention and Control: Once black sesame sprouts appear and the stalks begin to grow rapidly, apply a solution of 50% puerarin diluted 800-1000 times. Spray every 5-7 days for 2-3 applications to effectively control black spot, leaf blight, and stem blight. Regular monitoring and timely application are key to disease management. 6. Timely Harvesting: Sesame crops mature unevenly, so timing is crucial. Harvesting too early may result in underdeveloped upper seeds, while waiting too long can cause lower seeds to drop and lead to losses. It's best to harvest during the latter half of the flowering period, or about 5 days after pinching. After harvesting, allow the plants to dry for a while before threshing to ensure full seed maturity and better quality.
