The technique of planting alfalfa stem-cuttings in naturnal conditions was studied.The results showed (1) cutting bed should be a little higher than the ground level and well drained in order to avoid waterlogging, and plastic film, if used, should be one meter above the bed so as not to burn the cuttings by high temperature; (2) plastic film is a favourable covering in Spring and Fall, but not in Summer;While reed mat covering or no covering are the best way of all duriny rainy season; (3) the best seasons of cuttage are late spring and early summer while alfalfa is in bud stage; (4) there are no significantly bed effects on the survi al ratio of cuttings while they are 5-6 cm long;but in unfavourably natural conditions, 8 cm long cuttings are much beter.In general, thick cuttings are better than thin ones.
