地膜覆盖春芝麻栽培的要点（Key points for cultivation of spring sesame covered with plastic film） Key points for cultivation of spring sesame covered with plastic film Plastic mulch can make the yield of sesame reach more than 150 kilograms, and even more than 200 kg, so mulching is an effective measure to realize the super high yield of sesame. However, in order to realize the high yield of sesame seed film, we must seize the following key technologies: (1) timely early sowing: one of the main reasons for high yield of plastic film sesame is to make use of the warming and heat preservation effect of plastic film to advance sowing time, so as to make full use of light and heat resources and tap sesames high yield potential. Therefore, the film must be sesame early sowing, the suitable sowing date is the end of April to early May. Although the sesame mulching also has great effect on increasing yield, but the yield potential is limited, economic benefits is low. Of course, if a year only a spring sesame is not worth. In order to improve the cropping index, improve the planting efficiency, in the first crop of winter sesame short season vegetables (spinach, cabbage, fresh peas, Chines cabbage, garlic and other early clip), can also be used in intercropping, wheat, with the appropriate form of winter vegetables and wheat intercropping strips, spring vegetables harvest after planting, mulching after harvest of wheat, sesame, sweet potato, then interplanting summer cotton, peanut and other crops. (2) select the middle and late maturing fine sesame varieties with high yield potential: after the plastic film mulching, the effective growth period of sesame was prolonged. Therefore, it is suitable to plant some varieties of middle and late maturing sesame varieties which are tolerant to waterlogging, disease resistance and high yield potential, such as Yu Zhi, No. 5, No. 7, No. 8 and sesame hybrids. Only by selecting medium late maturing sesame varieties, can we make full use of the growi
