北京地区笋期定位施肥对早园竹退笋的影响
Effect of Site-Specific Fertilizer Application During Shooting Period on Phyllostachys propinqua Shoots Degradation in Beijing
摘要
Abstract
Bamboo shoot degradation directly affects the number of culms in bamboo forests,which in turn affects bamboo productivity.It is an important topic in bamboo forest tending and management,which needs to be studied.The paper takes Phyllostachys propinqua in Beijing to study the effects of fertilization on the rate of bamboo shoot degradation,the height of degraded bamboo shoot and the DBH of culms using site-specific application technology(applying liquid quick-acting fertilizer multiple times around bamboo shoots during the shooting period).The results show that:1)The rate of bamboo shoot degradation in the fertilization group is 41.3%,a decrease of 14.6 percentage points compared to the control group,and there is a significant difference between the two groups;2)The rate of bamboo shoot degradation is rising along with the time of shoot emergence,but the rising speed of fertilization group is slower than the control group;3)Fertilization can significantly increase the DBH of culms in the later stage of shooting period,which is 52.3%higher than the control;and 4)Fertilization has no significant effect on the height of degraded bamboo shoots.The results support the nutrition hypothesis to a certain extent for degraded bamboo shoots,and have certain significance for guiding bamboo forest management.关键词
