海拔高度及挖笋措施对黄甜竹出笋的影响

Effects of Different Altitude Gradients and Shoot Digging Measures on Shoot Emergence of Acidosasa edulis

为了延迟黄甜竹的出笋时间,增加竹笋产量,提高经济效益,选择在不同海拔高度竹林开展不挖笋、挖50%的笋、全部挖取3种挖笋措施对黄甜竹出笋影响的研究。结果表明:海拔高850 m的竹林黄甜竹自4月30日开始出笋,比海拔高140 m的竹林延迟29 d出笋;该海拔高度下,采取竹笋全部挖取处理时,出笋期长达70 d,比不挖笋处理延长了20 d,出笋量多达56115株/hm^2,竹笋产量高达17399.25 kg/hm^2。

In order to delay Acidosasa edulis shoot emergence time,increase its shoot yield and economic benefits,three kinds of shoot digging measures(digging no bamboo shoots,digging 50%bamboo shoots and digging all bamboo shoots)were selected to study the bamboo shoot emergence variation at different altitudes.The results showed that at an altitude of 850 m,the bamboo shoots emerged on April 30,29 d later than at an altitude of 140 m;furthermore,when the bamboo shoots were all excavated every time,the bamboo shoot period was 70 d,20 d longer than that of the control group(digging no bamboo shoots),with the maximum number of bamboo shoots 56,115 plants/hm^2 and the maximum yield of bamboo shoots 17399.25kg/hm^2.
