摘要
采用正交试验设计法研究了海拔高度、坡向和坡位对雷竹林出笋数、鲜笋产量和平均单笋质量的影响。结果表明,海拔、坡向、坡位3个立地因子均极显著地影响雷竹林的出笋数、鲜笋产量和平均单笋质量,雷竹笋用林造林应选择低海拔、阳坡和下坡的立地,其出笋数比平均值增加27.3%,鲜笋产量比平均值增加88.4%,单笋质量比平均值增加51.8%。
This paper studied the effect of altitude, slope direction and slope position on the quantity of shooting, fresh bamboo shoots yield and average weight of single bamboo shoot of Phyllostachys praecox by using orthogonal experimental design method. The results showed the three site factors, i.e., altitude, slope direction and slope position, had extremely significant effect on the quantity of shooting, yield of fresh bamboo shoots and average weight of single bamboo shoot. The shoot forest of Ph. praecox should be cultivated at the sites with low altitude, south faced slope and down slope. In this condition, the quantity of bamboo shoot increased 27.3% than average, the yield of fresh bamboo shoots soared 88.4% than the average, and the weight of a single bamboo shoot rose 51.8% than the average.
