通过对中型、乾宁狼尾草野生资源分布区年积温、降水量、最高温度和最低温度等气象资料及土壤类型分析,得出这两种狼尾草生长的适宜气候区限和土壤类型。并通过对收集到的全国898个县(市)相应气象资料和土壤类型相似性聚类分析,规划出这两种狼尾草适宜种植区主要为长江流域及淮河以南等水热较同步的地区。
Based on the meteorological data of annual accumulated temperature, precipitation, the maximum temperature and the minimum temperature of the wild resource distribution of Pennisetum chinense and Ganoderma lucidum, the suitable climatic zones and soil types for the growth of Pennisetum chinense were obtained. And through the cluster analysis of the corresponding meteorological data and soil type similarities collected in 898 counties (cities) in the whole country, it is planned that suitable planting areas of these two kinds of Pennisetum are mainly hydrothermal more synchronous than those in the south of the Yangtze River and the Huaihe River area.
