芝麻生育期间,常因阴雨渍害,阵雨、暴雨袭击或伏旱影响,不能高产、稳产。为了探索夏播芝麻的高产稳产途径和地膜覆盖栽培的增产效益,1986年,我县在地处丘陵的冷集区煤炭乡梁家畈村进行夏播芝麻地膜覆盖栽培试验、示范。试验地位于丘岗坡脚地段,地面较平,红砂土质,耕层较浅,地力不高,面积共4.16亩,其中地膜覆盖面积 Sesame during growth, often due to rain and rain stains, showers, heavy rains or the impact of drought, can not be high yield, stable yield. In order to explore the high-yielding and stable yielding seasons of summer sowing seeding and the yield-increasing benefits of plastic film mulching, in 1986, the county carried out summer sowing sesame mulching cultivation experiments and demonstrations in Liangjiadu Village, Coal Township, a cold area in the hilly area. The test site is located in the foot of the hillock slope, the ground is relatively flat, red sandy soil, shallow plow, low ground force, an area of ​​4.16 acres, of which mulching area
