Because during the summer sesame sowing period, temperatures are high and the weather is changeable. If drought occurs, the seedlings are easily "scorched to death," causing gaps in the stand; if heavy rain occurs, they are easily "smothered to death," also causing gaps in the stand.
Therefore, mechanized sowing is recommended, sowing 0.7 kg per 667 sq m, using a 24-row planter at a depth of 0.2 cm. Press the soil twice, before and after sowing. For manual sowing, first prepare the land, apply fertilizer, open furrows and make beds as usual, harrow the soil fine and level it, then sow 0.6 kg per 667 sq m, and after harrowing to cover the seed while taking advantage of the soil moisture (depth 2-3 cm), sow another 0.5 kg on top, then promptly roll and press the soil while taking advantage of the soil moisture.
Using the double-layer sowing method can achieve the purpose of double insurance. Under drought and high temperature conditions, although the surface-layer sprouts are scorched to death, the deep-layer sprouts can emerge smoothly; under heavy rain and waterlogged conditions, although the deep-layer sprouts are smothered to death, the surface-layer sprouts can emerge evenly and smoothly, ensuring a full stand from a single sowing.
