By using L₉（3⁴） orthogonal experiment design method，this paper discussed the effects of 3
factors，namely cutting size，kinds of growth regulator and concentration，on the survival rate of ice vegetable
branch cutting．The results showed that among the 9 combined treatments，the highest survival rate was 80%．
All 3 factors had significant effects on the survival rate．The cutting size is the main factor affecting survival
rate，followed by kinds of growth regulator．Regulator concentration had the least influence．As the ice plant
shoots changed from the secondary lateral branch （old branch） to fourth lateral branch （tender branch），the
survival rate showed the tendency of gradual increasing．The effect of growth regulator on the test indexes was
GGR ＞ IAA ＞ NAA．The best cuttage method was to select the fourth lateral branch（3-4 mm）and soaked
it in 50 mg·L^-1 GGR for an hour．The survival rate could be up to 90.56%．
