本研究对沙柳92个无性系,自1996~2000年进行了田间试验,筛选了高优质、高产量、高速生、高抗逆的达采、Ⅴ-Ⅱ、XⅣ-13、Ⅲ-01、XⅣ-08等10个优良无性系。研究结果表明,在沙柳无性系间速生性、抗逆性、适应性和生物量等数量性状存在丰富而广泛变异;其重要经济性状——生物量主要受树高、地径、叶重、叶数、萌条数和保存率等因子影响;树高、地径与生物量早晚期相关显著,其树高达到极显著水平;干枝比、枝下高与生物量呈负相关,选择可作为独立性状。
本研究對沙柳92箇無性繫,自1996~2000年進行瞭田間試驗,篩選瞭高優質、高產量、高速生、高抗逆的達採、Ⅴ-Ⅱ、XⅣ-13、Ⅲ-01、XⅣ-08等10箇優良無性繫。研究結果錶明,在沙柳無性繫間速生性、抗逆性、適應性和生物量等數量性狀存在豐富而廣汎變異;其重要經濟性狀——生物量主要受樹高、地徑、葉重、葉數、萌條數和保存率等因子影響;樹高、地徑與生物量早晚期相關顯著,其樹高達到極顯著水平;榦枝比、枝下高與生物量呈負相關,選擇可作為獨立性狀。

Field test of ninety-two clones was carried out from 1996 to2000.Seven excellent clones of good guality,high production fast growth and strong resistance were selected,involving Da Cai、Ⅴ-Ⅱ、ⅩⅣ-13、Ⅲ-01、ⅩⅣ-08 etc.The results showed there are rich and popular variation in many quantity characters such as fast-growth、resistance、adaption、and biological volume among clones of Salix psammophila.The most important economic character,biological volume,is much influenced by height、diameter、leaf weight、leaf number、Shoot number、survival rate and so on.In early and late days,the relation ships between height、diameter and biological volume are significant.The relationship between height and biological volume is highly Significant.The relation ships between trunk-branch ratio.height below the first branch and biological volume are negative.These can be viewed as independent characters.
