为改进育苗方法,于1982年在南京进行棉花地膜平铺覆盖营养钵育苗试验,取得了初步成效。地膜平铺覆盖营养钵育苗简称“地膜育苗”,就是用0.015毫米以下厚度的地膜(塑膜),平铺覆盖在营养钵苗床上,棉苗出土后破膜放苗,根在膜下生,苗在膜上长,育出的棉苗矮壮敦实,抗逆性强,移栽后缓苗期短,皮棉产量较高,纤维品质较好,并具有成本较低,管理简便,用工较少等优点。1983～1985年在继续研究的同时,在棉区进行示范,进一步完善这一项技术,目前在江苏淮北棉区已示范推广10万亩以上。
In order to improve the nursery method, we carried out the experiment of cotton film mulch covering nutrition bowl nursery in Nanjing in 1982, and achieved initial results. Plastic film tiling cover Nutritional Bowl Nursery Referred to as “plastic film nursery,” is the use of 0.015 mm thickness of the plastic film (plastic film), tiled cover in the nutritional bowl seedbed, broken out of cotton seedling Fangmiao, root in the film, Miao long on the membrane, sterile cotton seedlings dwarf, strong resistance, transplanted Huanmiao short, high lint yield, better fiber quality, and with lower cost, simple management, less labor Etc. From 1983 to 1985, while continuing to carry out research, demonstration was carried out in the cotton area to further improve this technology. At present, more than 100,000 mu have been demonstrated in the cotton area of Huaibei in Jiangsu Province.
