中国雷竹引种与适生区域

应用数量化回归对雷竹笋用林的立地条件作统计分析。结果表明：地形，坡向，土壤肥力，土壤质地，7月平均气温，春、秋季降水量等对雷竹生长有显著影响。进一步对气温和降水量等9个气象因子，运用模糊相似优先比方法，计算以长江中下游为中心的81个气象站与雷竹原产地之间的相似程度，结合雷竹生物学特性和实际生产经验，分划出3类适宜引种区。图1表2参4。

Division of introductionrange and suitable

Using the method of numerical measure，regression analysis aremade on site conditions of edible bamboo——Phyllostachys praecox．The result shows that slope，soil type，soil fertility，soil texture，mean annual air temperature and rainfall in spring and autumn，etc．，have an evident effect on the growth of the plant．On the base of climatic data from 81 meteorological stations in middle and lower reaches of the Changjiang River，9 climatic factors such as air temperature and rainfall are compared with these in original of the plant by the method of optimal ratio of fussy similarity．According to result and combining with biological property and practical experiment，3 kinds of introduction ranges are demarcated，which can provides scientific basis for introduction and cultivation farming of Phyllostachys praecox．
