How to sow spring and summer sesame seeds?
Spring sesame should adopt the method of "ploughing". The so-called "ploughing" means that after the previous crop is harvested, it is first fertilized, ploughed and raked before sowing sesame seeds. The advantages of "ploughing" are: it can turn the land and loosen the soil and increase the soil temperature; bury the bottom fertilizer and improve the fertilizer efficiency; reduce weeds and facilitate mid-ploughing; and the soil has good air permeability and can improve the ability of soil to store water and preserve fertilizer. Therefore, planting "ploughing" sesame is a key measure to increase production.
Summer sesame should advocate "iron stubble" sowing, rough sowing seminal tube. The sowing of "iron stubble" means that after the previous crop is harvested, no longer ploughing, ploughing and raking, as long as raking stubble, directly sow sesame seeds. Sowing sesame seeds with "iron stubble" can advance the sowing date of sesame seeds to early June, 5-10 days earlier than "ploughing". Due to the early sowing time, the light and temperature conditions in June are relatively fully utilized. Although the planting is relatively rough, as long as the management is strengthened, high yield can still be obtained, which is generally more than 10% higher than that of sesame seeds sown late due to "ploughing."

Cultivation technique of Spring Sesame with plastic Film mulching
Plastic film mulching cultivation can make the yield of sesame more than 150 kg per mu and some more than 200 kg per mu, so plastic film mulching is an effective cultivation measure to realize super high yield of sesame. The specific techniques are introduced as follows: 1. Seed selection and early sowing: after plastic film mulching, the effective growth period of sesame is prolonged. Therefore, excellent sesame varieties with high waterlogging resistance, disease resistance and high yield potential should be selected, such as Yuzhi No. 5, No. 7, No. 8 and sesame hybrids, which are suitable for early sowing and sowing from the end of April to early May, and make full use of the growing season to increase the yield of sesame. 2.
