Film mulching cultivation of various crops of many advantages, in recent years, the area is constantly expanding. One of the advantages of mulching, the growth of weeds has a great inhibitory effect, because the membrane temperature is higher, the general weeds will suffocate on a sunny day, except the monkshood this perennial weed will not only not boring Die, but due to the higher temperature in early spring film, grow more exuberant.
