以绿色植物生长调节剂GGR6号40、80mg·kg-12种浓度的溶液处理甘蒙柽柳插穗基部后进行扦插育苗试验，结果表明，用GGR6号处理甘蒙柽柳插穗，能显著提高插穗的生根率、成活率，促进根系和苗木的生长；2种浓度处理的插穗地径生长量分别比对照提高32％和30％，树高生长分别提高13．45和10．15cm；不同处理对根鲜质量影响差异极显著，对侧根数影响差异显著，对侧根均长影响不显著。
以綠色植物生長調節劑GGR6號40、80mg·kg-12種濃度的溶液處理甘矇檉柳插穗基部後進行扢插育苗試驗，結果錶明，用GGR6號處理甘矇檉柳插穗，能顯著提高插穗的生根率、成活率，促進根繫和苗木的生長；2種濃度處理的插穗地徑生長量分彆比對照提高32％和30％，樹高生長分彆提高13．45和10．15cm；不同處理對根鮮質量影響差異極顯著，對側根數影響差異顯著，對側根均長影響不顯著。
이록색식물생장조절제GGR6호40、80mg·kg-12충농도적용액처리감몽정류삽수기부후진행천삽육묘시험，결과표명，용GGR6호처리감몽정류삽수，능현저제고삽수적생근솔、성활솔，촉진근계화묘목적생장；2충농도처리적삽수지경생장량분별비대조제고32％화30％，수고생장분별제고13．45화10．15cm；불동처리대근선질량영향차이겁현저，대측근수영향차이현저，대측근균장영향불현저。
Forty, 80 mg· kg-1 GGR No. 6 （the green plant growth regulator agent） were taken to deal with the base of T. austromongolica cuttings and then were conducted cutting propagation experiments. Result shows that cuttings of T. austromongolica which were treated by GGR No. 6 can significantly improve their rooting rate, survival rate ＆ promote the growth of roots ＆ seedlings. Compared with the control, ground diameter increment of cuttings which were treated with two concentrations increase by 32% ＆ 30% ,respectively;tree height growth increase by 13.45 ＆ 10. 15 cm, respectively; difference of different treatments on root fresh weight, lateral root number ＆ average length of lateral root are very significant, significant, not significant.
