摘　　要：[目的]研究杞柳优良品种引种试验与生长规律。[方法]选择和引进4个优良品种:JW9-6与JW8-26是江苏省林业科学研究所从簸箕柳与杞柳正反杂交种中选出的优良无性系;绒柳和大红头是山东郯城县经多年栽培选育的优良品种。采用完全随机区组设计和裂区试验设计进行多点不同品种、不同密度的造林对比试验,对4个品种的扦插成活率、物侯期、抗性、地径生长规律、株高生长规律进行研究。[结果]引种试验研究表明:JW8-26、JW9-6、绒柳和大红头4个无性系品种在引种试验区能够露天越冬过夏,与原产地相比经济价值没有降低,所以此次引种试验是成功的。地径生长规律研究表明:4个品种的平均地径生长量的高速增长期在每年的3月10～5月10日,5月25日达到峰值,之后地径生长下降;地径平均增长速度的大小顺序依次是:JW9-6(26.82%)>绒柳(22.85%)>JW8-26(19.33%)>大红头(17.25%)。株高生长规律研究表明:4个品种的株高生长量从3月10～5月10日是快速生长期,2个月净增高136.2cm,第2个峰值在5月25日左右,平均净增高47.0cm,之后下降;株高平均生长速度的大小顺序依次是:JW9-6(46.99%)>大红头(44.24%)>绒柳(43.87%)>JW8-26(41.96%),但没有明显差异。[结论]为4个新品种在驻马店市低洼易涝地带和滩涂地带大面积栽培推广提供技术参考依据。[ Objective ] The research aimed to study the introduction trial on new varieties of Salix integra and its growth laws. [ Method ] This research chose and introduced 4 fine varieties. JW9-6 and JW8-26 were the fine clones chosen from the crossbreed of Salix suchowensis and Salix integra by Jiangsu Institute of Forest Science. Cryptomeriafortunei and Salix integra had been selectively cultivated in Taneheng for many years. These 4 varieties were compared with other different varieties in woods of different densities, by means of complete randomized block and split plot design. The research contents included the survival ratio of cuttage, phenophase, fastness, ground diameter growth laws and plant height growth laws. [ Result] The introduction trial showed that 4 clones could outdoor overwinter and spend summer, and the economic value did not reduce comparing to origin place, so this trial was success. The study of ground diameter growth law of Salix integra showed that the rapid period of the ground diameter growth increment was from March 10th to May 10th, and the May 25th reached the peak value, then began to drop. The average ground diameter growth rate was in order： JW9-6 （26. 82% ） 〉 Cryptomeria fortunei（22. 85% ） 〉 JW8-26 （ 19. 33% ） 〉 Salix integra（ 17.25% ）. The study of plant height growth law of Salix integra showed that the rapid growth period of the plant height growth increment was from March 10^th to May 10^th, and the May 25^th reached the second peak value, and the average net added height was 47.0 cm, then began to drop. The average plant height growth rate was in order： JW9-6（46.99% ） 〉 Salix integra（ 44. 24% ） 〉 Cryptomeriafortunei （43.87%） 〉 JW8-26（41.96% ）, but had no significance. [Conclusion] The study can provide a reference for cultivating these 4 varieties in low-lying belt and tidal flats in Zhumadian.
