How to preserve sesame seeds in summer
Ensuring that summer sesame seeds are fully seeded is an important measure to improve the yield of summer sesame. However, during the sowing of summer sesame seeds, the temperature is high and the weather is changeable. If it encounters drought, it is easy to “suddenly die†and the seedlings are serious; if it encounters heavy rain, it is easy to “sad†and lack of seedlings.
It is recommended to use the double-layer seeding method to achieve the full seedling of summer sesame seeds. Mechanized sowing, 0.7 kg per acre, planted with 24 rows of seeders, 12 rows of deep sowing, depth of 3-4 cm, another 12 rows of shallow sowing, depth of 0.2 cm, two suppression after sowing. Artificial sowing, firstly according to the conventional land preparation fertilization ditch for sputum, after the mantle is finely leveled, 0.6 kg per mu, after robbing the cover seed (depth 2-3 cm) and then used to broadcast 0.5 kg, and then timely Robbery and suppression.
Double-layer seeding can achieve the purpose of double insurance. In the case of high temperature and drought, the surface seed buds are drowned, and the deep buds can be unearthed. In the case of heavy rain and water, the deep buds are suffocating, but the surface germination can be smoothly seeded to ensure a broadcast. The whole seedlings lay a good foundation for the high yield of summer sesame seeds.
