新疆特别是喀什地区长期以来,在生产中葡萄繁殖常用的是春季硬枝扦插繁殖法,从育苗情况看,大面积育苗的成活率都比较低,在30%—50%左右,主要原因是:①插条在运输过程中失水严重,降低发芽率;②新疆春季气温上升快,而地温却较低,与插条先发根而后发芽的要求背道而驰。③虽采用地膜覆盖,但由于春季温度变化大不能及时管理,死亡较多。为了提高扦插育苗成活率,本人通过连续三年的试验,总结出葡萄秋季扦插繁殖新方法,可使成活率达90%以上。此法既省工省力,又可迅速推广运用。
Xinjiang, especially the Kashgar region has long been in the production of grape replanting is commonly used in spring hardwood cutting propagation law, from the nursery situation, the survival rate of large area nursery stock are relatively low, at 30% -50%, mainly due to: ① cuttings in the transport process of serious dehydration, reducing the germination rate; ② Xinjiang spring temperatures rise faster, while the ground temperature is lower, and the germination of the first root of the cuttings run counter to the requirements. ③ Although the use of plastic film cover, but due to large temperature changes in the spring can not be managed in time, more deaths. In order to improve the survival rate of cutting seedlings, I passed three consecutive years of experiments, summed up the grape cuttings in autumn a new method can make the survival rate of 90%. This method not only saves labor, but also quickly promote the use of.
