Effects ofFloor-covering Material on the Shoot Production in the Stands of Phylostachs praecox Chu et Chao

Adopting the method of randomized blocks design,the effects of eight kindsof floor-covering materials were studied in the stands of Phyllostachys praecox. The resultsshowed that the stand floor-covering increased the stand's soil temperature,made the shootsemerge earlier and prolonged shooting period as well as raised shoot production and its value. After comprehensively evaluation,rice chaff was the best material.As compared with thecontrol,it could raise the soil temperature 3.83℃ higher,shift the shooting time 41 days earlier,prolong shooting period 40 days more and raise the shoot production value and stand'seconomic benefit 29.4%,270.3% and 310.2% respectively.
