[Objective]To investigate the effects of plastic film mulching on plant traits and yield of Chrysanthemum morifolium andinhibition effect on the weeds during growth period. [Methods] The 2 kinds of treatment,black plastic film mulching and open field cultivation were set,using randomized block design,to observe the growth of weeds,and the yield and some main plant characters were analyzed. [Results]Flower yield of each district were analyzed of the two treatments,plastic film mulching and open field cultivation,were analyzed by variance analysis,and the results were F = 25. 8 ﹥ F0. 01( F0. 01= 21. 2),which indicated the two treatments showed significant difference; thereinto,F values of the plant height,total number of branches and total flower number were 1. 7,4. 0 and 1. 4,which were less than F0. 05( F0. 05= 7. 7),while F values of the diameter and 100 inforescence flesh weight were 10 and 13. 8,which were higher than F0. 05,and all of these results indicated that the treatments were significantly different. [Conclusions] Compared to open field cultivation,film mulching cultivation can effectively inhibit the growth of weedss,and had no significant effects on the plant height,total number of branches and total flower number of Chrysanthemum morifolium,and can increase the plant fresh weight diameter and hundred flower inflorescence significantly,increasing output at extremely significant level.
