The Effect of Bamboo Density on the Yield of Chimonobambusa pachystachys Shoots in Gulin County

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.
