Occurrence law and control technology of weeds in new afforestation of Camellia oleifera
At present,researches on weeds in Camellia oleifera forest is rare.In order to provide some scientific basis for safely weeding and controlling weeds in C.oleifera forest,occurrence law and damage stituation of weeds in young C.oleifera forest in Dujiachong Forest Farm of Hunan Academy of Forestry were investigated,summarized and analyzed,and control effect of three treatments of film mulching,mowing-burying grass,chemical weeding on controlling weeds were researched.The results showed that there were 22 families and 43 species of weeds in the C.oleifera forest.Gramineous weeds accounted for 23％,and broadleaf weeds accounted for 77％.There were 9 species of annual weeds,accounting for 21％,and 34 species of perennial weeds,accounting for 79％.All weeding ways could effectively inhibit growth of weeds.Based on effects of controlling all weeds from strong to weak,the order of the treatments was chemical weeding,mowing-burying grass,film mulching,CK;based on effects of controlling gramineous weeds from strong to weak,the order was chemical weeding,mowing-burying grass,CK,film mulching;based on effects of controlling broadleaf weeds from strong to weak,the order was chemical weeding,mowing-burying grass,film mulching,CK.In view of toxicity of glyphosate,it was suggested to promote mowing-burying grass technology combinating with mechanization.
