摘要
为了选择旱作条件下科尔沁沙地南缘适生杨树(Populus spp.)品种,敖汉旗于2007年对18个杨树品种进行沙地旱作栽培试验,2023年8月,采用样带法抽样,对单位面积蓄积量、枯梢病情指数、干部病害3个指标排序并赋分,按总得分由低到高确定选择先后顺序,最终选择黑林1号、白林3号、B6、白林2号(棱)为科尔沁沙地南缘适生品种。
In order to select suitable Populus spp.varieties for rainfed cultivation at the southern margin of the Horqin Sandy Land,a trial was conducted in Aohan Banner in 2007 involving 18 poplar varieties.In August 2023,samples were collected using the transect method,and three indicators—volume per unit area,tip blight index,and trunk disease—were ranked and scored.The varieties were then selected in order from lowest to highest total score.Ultimately,Heilin No.1,Bailin No.3,B6,and Bailin No.2(Leng)were chosen as the suitable varieties for the southern margin of the Horqin Sandy Land.
