采用随机区组设计，试验了氮、磷和钾水平不同组合的复合肥配方系列及尿素对赤水河流域毛竹林生产力的影响。结果表明：①不同处理对毛竹林出笋成竹量和成竹率、新竹平均胸径和胸高断面积、以及竹秆、枝叶等地上生物量有增产效应，差异不显著。综合效应指数排序为复合肥F （271．34％）＞尿素（228．33％）＞复合肥G （160．46％）＞对照（100．00％）。②复合肥F的出笋量、成竹量、新竹平均胸径、胸高断面积，秆材量和枝叶生物量分别为对照的110．53％、107．22％、103．61％、113．62％、114.93％和109．70％。除出笋量增幅仅中下水平外，成竹量、新竹质量和生物量增幅较大，适宜于毛竹林大径材培育。③复合肥G和尿素的出笋成竹量增幅较大，复合肥G的新竹质量和生物量增幅较小，不及尿素的中上水平，前者可作为笋用林和笋材兼用林培育肥种、肥效较低，后者肥效应较高、不利于地力维护，生产上宜慎用。

This paper experimented in the influences of urea and compound fertilizer series formed different N ,P and K levels on moso bamboo forest productivity in chishui river basin of Guizhou province ,China , using the randomized block design .The results showed that :(1) Different treatments on moso bamboo forest had increasing yields effects on shooting and bamboo rate ,average diameter (DBH) and sectional area(SAH) at breast height ,the ground biomasses of stem ,and branches and leaves of new bamboo ,and the difference was not significant . Comprehensive effect index is sorting for compound fertilizer F (271.34% )> urea(228.33% )> compound fertilizer G (160 .46% ) > control (100 .00% ) .(2) Com‐pared with control ,compound fertilizer F at amount of shooting and new bamboo ,DBH and SAH ,bio‐masses for stem and branches and leaves of new bamboo were 110 .53% , 107 .22% , 103 .61% , 113.62% ,114 .93% and 109 .70% ,respectively .Except the amount of bamboo shoot increasing middle and lower ,bamboo amount ,DBH and SAH and biomasses were increasing higher in compound fertilizer F ,it is suitable for large DBH wood cultivation of moso bamboo forest .(3) Amount of shooting and bamboo of compound fertilizer G and urea is higher .DBH ,SAH and ground biomass growth of com‐pound fertilizer G is lower ,less than the upper level of urea .The former with low fertilizer effects ,can be used as the bamboo forest of shoot and combination of shoot and timber ,the latter with high fertilizer effects ,is not conducive to maintenance of soil fertility .These production should be careful .
