根据中华红叶杨(Populus×euramericanacv.zhonghuahongye)的生物学特性,研究了平茬更新代次中华红叶杨苗木地上部分和地下部分生长情况,确定了中华红叶杨最佳平茬代次,同时为大面积扩繁培育中华红叶杨苗木提供理论参考。 According to the biological characteristics of Populus × euramericanacv.zhonghuahongye, the growth of the aerial part and the underground part of Populus tomentosa seedlings under the stubble replacement stage was studied. The optimal stubble generation of Populus simonii was determined, Area expansion propagation of Chinese red leaf poplar seedlings provide a theoretical reference.
