摘要
通过对苏柳172、795、799三个无性系在洞庭湖区的引种栽培试验,研究了不同长度截杆扦插造林与耐水性的关系及三个无性系不同规格苗木造林生长对比,结果表明苏柳795耐水性最强,没顶淹水13 d存活率仍达98%,各无性系前期生长及其不同规格苗木的前期年均生长量无显著性差异。
Based on research of the introduction and breeding experiment of three done species of Solix jiansuensis 172,795 and 799 in Dongting Lake area. The relationship between the different length of stem cutting and water resistence, and the growth rate of three clones were studied. The results showed the strongest water resistance was clones 795 and survival rate was 98 % of 13-day top flooding. There is no significant difference in early growth period of each clones and average growth volume in early period of different style seedling.
