Collection and Treatment of Poplar Scion and Improvement and Selection of Graft Variety

我国北方在植树造林方面对于杨树的需求量特别大,种植杨树对于改善环境具有重要作用。但是随着种植面积的不断扩大,到了中后期杨树普遍出现不同程度的生长缓慢、抗逆性降低等问题。因此,为改善杨树的生长状况,文章通过对杨树接穗采集处理及嫁接换代品种改良选择进行研究,希望对今后杨树的植树造林有所帮助,同时也为今后苗木品种改良积累经验。

In the north of China,there is a great demand for poplars in afforestation,and planting poplar plays an important role in improving the environment.However,with the continuous expansion of planting area,poplar generally appeared some problems such as slow growth and reduced stress resistance in the middle and later stage.Therefore,in order to improve the growth status of poplar,this paper studies the collection and treatment of poplar scion and the improvement and selection of grafting varieties,hoping to be helpful to the afforestation of poplar in the future and accumulate experience for the improvement of seedling varieties in the future.
