摘　　要：针对不同施肥量对金佛山方竹竹笋的影响进行了研究,结果表明：施用不同施肥量的复合肥对金佛山方竹发笋株数和产量都有明显的促进作用,对发笋地径的促进作用较小,但是相对于未施肥,其发笋的地径也有一定的增加;不同留竹密度对其发笋株数、地径和发笋产量也有一定的影响。综合以上结果可以初步得出以下结论：留竹密度在2.3~2.5万株.hm-2,复合肥使施用量1~1.5 t.hm-2（0.1~0.15 kg.m-2）能有效促进方竹的发笋株数,增大发笋地径,从而提高发笋产量;留竹密度太多或者太少,施肥量太高都对提高方竹笋产量无益。The bamboo shoots of Chimonobambusa utilis were studied under different fertilizer dose. The results showed that various compound fertilizer amounts were of benefit to both the number and yield of bamboo shoots . The benefit was not significant for the shoot diameters, although to some extent they were greater than CK. The diameter, number and yield of bamboo shoots under different parent shoot densities were different. The number, yield and diameter, were improved when parent shoot density was from 23 000 to 25 000 individuals · hm-2 and the amount of compound fertilizer was from 1 000 to 1 500 kg · hm-2
