1983年11月,我们在商水县姚集乡张庄村的两条沟渠边带叶栽植意大利杨一年生苗2500株,1984年6月调查,成活率97.6%。试验证明,带叶栽植是提高意大利杨成活率的一条新途径。意大利杨喜温暖湿润的气候,生长迅速。春季栽植由于地上部分和地下部分水分失调,往往发生生理干旱,造成死亡。秋末气温逐日迅速下降,地上部分蒸腾作用减
In November 1983, we planted 2500 annual seedlings of young Italian poplar at the side of two ditches at Zhangzhuang Village, Yaoji Township, Shangshui County. In June 1984, we investigated the survival rate of 97.6%. Experiments show that with leaves planting is to improve the survival rate of Italy Yang a new way. Italy Yang hi warm and humid climate, rapid growth. Spring planting due to the aboveground and underground water imbalances, often physiological drought, resulting in death. Autumn temperatures dropped rapidly daily, transpiration on the ground less
