银中杨继承了白杨派树种的遗传特性,其生根能力较青杨和黑杨派树种低,常规扦插繁殖的成活率只有30%,甚至更低。通过近几年的试验,总结了一些培育经验。1、育苗地的选择:应选择地势平坦、地下水位较高、透气性好、有机质含量较高的沙质壤土,pH值中性或偏酸性的土壤。2、整地时间
Yin Zhongyang inherited the genetic characteristics of Poplar tree species, its ability to take root than Populus and Populus to send low tree species, the survival rate of conventional cutting propagation is only 30%, or even lower. Through experiments in recent years, summed up some experience in nurturing. 1, the choice of nursery: should choose flat, high groundwater level, good air permeability, high organic matter sandy loam, pH neutral or acidic soil. 2, site preparation time
