芝麻地膜覆盖技术是八十年代初由中国农科院油料作物研究所等单位开始研究的。近十年来.经过大量的试验、示范和生产实践证明,芝麻地膜覆盖有提高地温、防旱防溃、改善土壤结构、促进土壤有机质分解、抑制杂草、减轻病害、促进生长和提早播期、扩大种植区域等作用,一般可使芝麻每亩增产25-40公斤,增产30-60％,旱涝年份增产幅度更大,可达一倍以上。如河南省经济作物技术推广站1985-1987年3年48个点次试验,地膜覆盖栽培的平均亩产90.8公斤,比对照亩增29.9公斤,增产49.1％;项城县城郊乡解庄行政村1985年30亩地膜覆盖栽培
Sesame film mulching technology in the early eighties by the Chinese Academy of Agricultural Oil Institute of Oil and other units began to study. Over the past decade, after a large number of experiments, demonstrations and production practices have proved that sesame mulching has the effects of increasing ground temperature, preventing drought and preventing collapse, improving soil structure, promoting decomposition of soil organic matter, suppressing weeds, reducing diseases, promoting growth and early sowing, Expanding the role of planting areas, the general sesame per hectare yield 25-40 kg, an increase of 30-60%, drought and flood years yield more, more than doubled. For example, Henan Province Economic Crops Extension Station from 1985 to 1987, 48 points in three years of tests, mulching cultivation average yield of 90.8 kg, compared with the control of acres by 29.9 kg, an increase of 49.1%; Xiangcheng County suburbs Jie Zhuang administrative village In 1985 30 acres of plastic film cultivation
