Summer and autumn oil wheat cultivation techniques

2. Optimal sowing time. For summer sowing, it's best to plant between late June and early July. Use 50 grams of seeds per acre, with seedlings aged between 25 to 30 days, and transplant them in late July or early August. Autumn sowing should be done from late July to early August, using 40 to 50 grams of seeds per acre.

3. Seed treatment. Due to the hot weather, drought, and rainy season during the seedling stage, it's recommended to pre-soak and germinate the seeds before planting. Soak the seeds in cold water for about an hour, then wrap them in gauze and keep them at a temperature of 15°C to 20°C. After 2 to 3 days, the seeds will be ready for sowing.

4. Field management. Select plots that are elevated, have fertile soil, good drainage, and avoid areas where Compositae crops were previously grown. Apply a base fertilizer of 5,000 kg of well-rotted manure per acre, along with 40 kg of diammonium phosphate, 20 kg of urea, and 20 kg of potassium sulfate, or 200 to 300 kg of wood ash. After sowing, place small arch frames made of bamboo on the seedbeds, and cover them with shade nets or old plastic sheets to protect against rain and reduce heat. Keep the field consistently moist and the soil loose throughout the growing period. Apply foliar fertilizers 2 to 3 times, using solutions like 0.2% potassium dihydrogen phosphate or 0.2% to 0.5% urea solution.

5. Timely harvesting. Harvest when the oil wheat has 30 to 34 leaves and reaches a height of 45 to 48 cm. Cut the plants about 2 to 3 cm above the ground to ensure quality and ease of handling during transportation and sale.
