Land preparation and sowing methods for spring sesame and summer sesame

Spring sesame should adopt the "plowed furrow slice" method. The so-called "plowed furrow slice" means that after the previous crop is harvested, fertilizer is applied, the soil is plowed and harrowed, and then sesame is sown. The advantages of "plowed furrow slice" are: it can turn the soil and loosen it, increasing soil temperature; bury the base fertilizer, improving fertilizer efficiency; reduce weeds, making intertillage convenient; and the soil has good aeration, which can improve the soil's water storage and fertilizer retention capacity. Therefore, planting "plowed furrow slice" sesame is a key measure for increasing yield.

For summer sesame, "iron stubble" sowing should be advocated, with rough sowing and careful management. "Iron stubble" sowing means that after the previous @#@245@#@ crop is harvested, there is no further plowing, plowing or harrowing; as long as the stubble is raked once, sesame is sown directly. With "iron stubble" sowing of sesame, the sowing period can be advanced to early June, 5-10 days earlier than "plowed furrow slice". Because the sowing period is earlier, the light and temperature conditions in June are relatively fully utilized. Although the planting is relatively rough, as long as management is strengthened, high yields can still be obtained, generally increasing yield by more than 10% compared with sesame sown late because of "plowed furrow slice".
