棉花地膜覆盖营养钵育苗,就是将聚乙烯塑膜(地膜)平铺在营养钵苗床上,棉苗出土后破膜放苗。这种育苗方式(简称地膜育苗)是棉花营养钵育苗移栽的三代技术。第一代为温床及露地育苗,第二代是塑料薄膜棚架育苗。地膜育苗,棉苗根在膜下生长,发育良好;茎叶在膜上自然环境中生长,敦实茁壮。因此,育出的棉苗抗逆性强,移栽后恢复生长快,是一项夺取优质、高产、省工、低成本
Cotton mulching plastic seedlings nutrition nursery, that is, polyethylene plastic film (film) tiled in the nutritional bowl seedbed, broken out of cotton seedling Fangmiao. This method of raising seedlings (referred to as plastic film seedling) is the three generations of transplanting cotton seedling nutrition Bowl technology. The first generation of hotbed and field nursery, the second generation of plastic film scaffolding nursery. Seedling nursery, cotton seedling root growth under the membrane, well-developed; stems and leaves in the membrane growth in the natural environment, it is robust. Therefore, the cotton seedlings raised strong resistance, fast recovery after transplanting, is a capture of high quality, high yield, labor-saving, low-cost
