闽东北周宁县山地方竹不同立竹密度与施肥对出笋产量的影响

Effect of Different Bamboo Stand Densities and Fertilization on the Bamboo Shoot Yield of Chimnobambusa quadrangularis(Fenzi)Makinoin Zhouning County in Northeastern Fujian

在田间采用两向分组实验设计方法,研究了方竹林不同立竹密度与施肥对出笋产量的影响,并进行了统计分析,结果表明：在方竹竹龄结构调整到1~4年生竹子各占25%的条件下,立竹密度控制在12000~15000株/hm2时对出笋产量的影响不大,而施肥能有效提高山地方竹林的出笋产量,其中以A3B1组合处理的效果最佳,既能极显著地提高出笋产量,又能极显著地提高笋的质量。

We used two--wayclassificationmethod in the fieldtostudytheeffectof different bamboo stand densities and fertilization on the bamboo shoot yieldinChimnobambusa quadrangularis （Fenzi） Makino. Through the statistical analysis, the results showed that..with bamboo age structure adjusted to 1-4 years under the condition of 25 % respectivelyandthe bamboo stand density between 12000 and 15000 plants/hm2,it had little effect on the bamboo shoot yield, while fertilizer could effectively increase the bamboo shoot yieldof Chimnobambusa quadrangularis （Fenzi） Makino, of which A3B1 combination＇s processing effect wasthe best andcould significantly improve the bamboo shoot yield, and the quality of bamboo shoots.
