为了探索赣北棉区棉花地膜复盖栽培技术的增产效果和经济效益,1982年,我区在七个产棉县布置了14个试验示范点,进行了棉花地膜复盖栽培试验,面积共66亩。试验分为一熟棉田地膜复盖、两熟棉田地膜复盖;全复盖、半复盖;全生育期复盖、半生育期复盖;先播后盖、先盖后播等八种处理,均以不复膜为对照,并附设示范区。综合各点收获产量结果:复膜棉田试验区平均亩产皮棉156.3斤,比对照平均净增皮棉21斤,增产15.5％。
In order to explore the yield-increasing effects and economic benefits of cotton mulching and covering cultivation techniques in the cotton fields in north Jiangxi, in 1982, 14 pilot demonstration sites were set up in seven cotton producing counties in our district for cotton mulching and covering cultivation with a total area of 66 mu. The experiment was divided into a mature cotton field plastic film cover, double cotton field plastic film cover; full coverage, semi-covered; full growth period cover, half-growth period cover; , Are not complex as a control, and attached demonstration area. Comprehensive harvest yield results: Fumo cotton field test area average yield of lint 156.3 kg, compared with the average net increase of lint 21 kg, an increase of 15.5%.
