摘要: 为探究立竹密度对方竹林笋产量的影响，2017年6月在泸州市古蔺县国有林场以间伐手段进行了立竹密度调控实验，实验设置对照（CK）、4万株·hm-2（N1）、5万株·hm-2（N2）、6万株·hm-2（N3）和7万株·hm-2（N4）5种处理。结果表明：方竹笋期为9月中下旬至10月中下旬，持续时间约30 d，出笋量随采笋时间的推移表现出先增加后减少的规律，出笋量主要集中在中后期；N1和N2处理的笋产量均低于CK，但不显著，N3和N4处理的笋产量都显著高于CK；回归分析表明，方竹林产笋最适立竹密度为7.40万株·hm-2。可见，立竹密度对方竹林笋产量有着重要影响，合理的立竹密度能显著提高笋产量。Abstract: In order to study the effect of bamboo density on the yield of Chimonobambusa pachystachys shoots, the control experiment of bamboo density was carried out at Gulin State-owned Forest Farm of Luzhou in June 2017. In our experiment, five treatments were designed, including control (CK), 40,000 plants·hm-2 (N1), 50,000 plants·hm-2 (N2), 60,000 plants·hm-2 (N3) and 70,000 plants·hm-2 (N4). The results indicated that the shooting period was from mid tolate September to late October and lasted for approximately 30 days. And, the main period of bamboo shoots were the middle and late stages of the whole period. The yield of bamboo shoots of N1 and N2 was insignificantly lower than CK. However, the yield of bamboo shoots of N3 and N4 was significantly higher than CK. Regression analysis showed that the optimum bamboo density of Chimonobambusa pachystachys was 74 000 plants·hm-2. In other words, there was a significant correlation between bamboo density and the yield of bamboo shoots, and the yield of Chimonobambusa pachystachys shoots could be significantly improved by a reasonable bamboo density.
