Objective: To study the effections of Angelicae Sinensis Radix film mulching modes on the yield and component factors during the medicine formation period. Method: An experiment research was made to plant Angelicae Sinensis Radix by 6 different film mulching modes:half-covered with white film

full-covered with white film

half-covered with black film

full-covered with black film

the film side planting

and earthing the whole film planting

compared with open field cultivation. Result: Results indicated that among plastic film mulching cultivation modes

the film side cultivation was the lowest in the Angelicae Sinensis Radix emergence rate

number of plot harvested plants

single fresh root weight and yield. However

all of plastic film mulching cultivation treatments were better than that of open field cultivation. The fresh weight of single root of angelica was the heavest

42.95 g/plants and yield was the highest up to 6 056.25 kg· hm-2 by using white film half covering mode while that was the lowest level by using open field cultivation

respectively

28.47 g/plants and 3 087.50 kg· hm-2. Compared with CK

half-covered with white film

full-covered with white film

half-covered with black film

full-covered with black film

the film side planting

and earthing the whole film planting modes in turn was increased by 96.15%

91.90%

89.27%

70.65%

58.10%

13.97%. Conclusion: Recommended that cultivation modes of half-covered and full-covered with black film were used in more weeds areas to plant the Angelicae Sinensis Radix in order to save the weeding labor

achieve costs saving and increase the yield; cultivation modes of half-covered and full-covered with white film were used in less weeds areas.
