在贵州省赤水河下游46hm2试验林中设立38个20m ×20m固定样地定位监测毛竹林日出笋成竹动态，并用3因素3重复随机区组设计分析清林松土、清林措施对出笋成竹量的影响。结果表明：①毛竹林出笋始于3月中旬、止于4月中旬，年出笋量1388牧/hm2、年成竹量867牧/hm2、平均成竹率62．44％，日出笋和成竹数量及成竹率动态呈“低－高－低”曲线，成竹率日动态峰值较出笋成竹量峰值提前5～10 d ，日出笋和成竹量间正相关显著。②新竹平均胸径的日动态呈降低趋势，变幅6．00～14．00cm。③不同抚育措施可提高毛竹林出笋和成竹数量，出笋量差异不显著，成竹量和成竹率在处理和对照间差异显著。

There were 38 fixed plots established to monitor the daily dynamics of bamboo shooting and stocking ,and randomized block design for 3 factors 3 repeats to analysis the influence of rehabilitation and cutting brush ,cutting brush measures on bamboo shooting and stocking percentage ,with 20 m × 20 m samples in 46 hm2 experimental forest of Phyllostachys heterocycla cv .pubescens in downstream of Chishui rivesheld ,Guizhou province .Results show that :(1) Bamboo shooting of Moso bamboo forest began in mid-March ,ended in mid-April ,there were annual bamboo shoots for 1388 sp/hm2 ,bamboo a-mounts for 867 sp/hm2 ,and average bamboo rate for 62 .44% .Daily dynamics of bamboo shoots and bamboo amounts ,and bamboo rates show “low-high-low”curve lines ,dynamic curve peak of bamboo rate was 5-10 days in advance of bamboo shoots and bamboo amounts peak .Daily bamboo shoots and bamboo amounts correlated just significantly .(2) Daily dynamics of average diameters at breast height of new bamboos trend to reduce ,and the range of 6 .00 to 14 .00 cm .(3 ) Different tending measures can im-prove the numbers of bamboo shoots and bamboo amounts of Moso bamboo forest ,the bamboo shoots difference was not significant ,bamboo amounts and bamboo rate significant difference between treat-ments and contrast .
