Abstract:In order to raise the yield of Lei bamboo sprout and move up the season of bamboo shooting,the planting trial was carried out in Phyllostachys praecox f.prevelnalis plantations.The results showed that the mean yield of all experimental plots increased by 24.7%over the control,the highest plot increased by 78.1%over.In all experimental plots,the season of bamboo shooting was moved up 3 to 5 weeks earlier than the control,and the earliest one was 8 weeks ahead of the control.Owing to the yield of bamboo sprout increased and shooting season moved up,a vast amount of bamboo sprout could supply to the market of the Spring Festival with high price.The mean output value and pure income were increased by 267.3%and 321.4%over the control respectively.To the best one,the output value and pure income were increased by 495.3 and 531.2%respectively.The mean ratio of input to output was over 1:4 in the experimental plots and the highest one was 7:12.The best way selected in this study was that at the end of November to the begining of December,urea was applied to the upper layers of the soil at the rate of 75 g per square meter,then the bamboo forest land was covered with bamboo leaves at the thickness of 30 cm imme- diately.
