1. Soil preparation and fertilization: choose sandy loam or loam fields with loose soil, good air permeability and medium-to-high fertility, and avoid continuous cropping. At the end of May and the beginning of June, 15 kg of urea vegetables or 25 kg of ammonium bicarbonate and 5-10 kg of potassium chloride were applied per mu. two。 Seed treatment: dry the seeds for 1-2 days before sowing. In order to control sesame black spot and stem spot blight, the seeds were soaked in warm water for about 15 minutes with 50 ℃ 55 Mel. After cooling, the seeds were removed and sowed dry. The sowing rate is 0.5 kg per mu. 3. Inter-seedling fixed seedling: the first pair of true leaves of the seedling unfold time seedling. When 3 pairs of true leaves were produced, the seedlings were fixed according to the row spacing of 15 × 20 cm, and the seedlings were dense and thinned, leaving enough strong seedlings of 8000Mel 10000 seedlings per mu. 4. Topping at the right time: about 1 cm in length of the main stem and the tip of each branch was removed for 20 days after the early flowering stage. 5. Prevention and control of diseases: after budding of black sesame, when the stem grows rapidly, spray with 50% hydantoin 800: 1000 times liquid, spray every 5 mi every 7 days, control 2 mi for 3 times in a row, can effectively control black spot, leaf blight and stem spot blight. 6. Timely harvest: the maturity of sesame is very inconsistent. If the harvest is too early, the upper seed can not mature; if the harvest is too late, the lower seed is easy to fall off, resulting in loss. It should be harvested from half a month to 20 days after the final flowering, or about 5 days after topping. After harvest, store it for a period of time before threshing, so that the seeds are fully ripe.
