摘　　要：对毛竹笋材两用林进行了平衡施肥技术的研究,结果表明:配方施肥能有效地促进毛竹笋、材的生长,所设7个试验处理中,以N2P1K1(1∶0.30∶0.22)和N1P1K2(1∶0.68∶0.98)表现较优。N2P1K1为增加出笋数和新竹数的最佳处理,同时也能较有效地促进竹径增粗和提早出笋;N1P1K2为增粗竹径、促进枝下高增高的最佳处理,在提高单株笋重和增加出笋数上则为其次。The effect of optimun amounts and proportions of fertilizers on bamboo shoots and timber was studied. The results show that: Optimum amounts and proportions of fertilizer can stimulate the growth of bamboo shoots and timber prominently. Among the seven treatments, N_2P_1K_1(1∶0.30∶0.22) and N_1P_1K_2(1∶(0.68)∶0.98) are more effective than the others. And N_2P_1K_1 is the best treatment in multiplying the number of bamboo shoots and new culms, which can also enlarge the mean diameter of stems and facilitate earlier emergence of shoots. In addition, N_1P_1K_2 is the best treatment in increasing the mean diameter and heighten the first branch's position in the stem, whose effect is the second most dominant in promoting the average weight and amount of bamboo shoots.
