种好地膜棉,技术是关键,应特别注意如下技术要点:一要选好地块:并不是所有的地块都能进行覆膜植棉。地膜棉应选土地平,土质好,土层深,肥力较高,排灌方便的地块。坡地、瘦地、低湿田、飞砂地等都不宜种地膜棉。二要平整好土地:要求厢(畦)面;平,土粒细,无坷垃,无根茬,以便于地膜与厢面紧贴,更好地发挥其增温保墒作用。厢土宜上虚下实,使播下的棉籽便于吸水萌芽,扎根出苗。三要施足基肥:与露地栽培相比,地膜棉更需重施基肥。因为,地
Good cotton membrane technology, technology is the key, should pay special attention to the following technical points: First, to select the land: Not all plots can be covered with cotton. Cotton film should be selected flat land, good soil quality, deep soil, high fertility, irrigation and drainage of plots. Slope, thin, low wet fields, flying sand, etc. are not suitable for cotton film. Second, the formation of good land: requirements Xiang (畦) surface; flat, fine soil, no Ke rub, root stubble in order to facilitate the close contact with the film surface and better play its role of warming soil moisture. Habitat on the soil should be virtual reality, so that sowing cotton buds to absorb water, take root emerge. Third, the application of foot-based fertilizer: Compared with open-field cultivation, plastic film need to re-apply more base fertilizer. Because, to
