阿月浑子在甘肃省引种栽培区的划分

为了使阿月浑子的引种栽培工作能够在自然条件多样、立地类型复杂的甘肃省内有效地开展,对甘肃省内不同气候区的22个样点和新疆喀什、和田2个样点及国外阿月浑子栽培区的6个样点共计30个样点的8项气候要素进行了综合气候因子系数分析。结果表明,根据不同温度、热量、降雨及光照条件,可将30个样点划分为4个气候类型区:适宜区2类,即适宜阿月浑子生长的地中海气候区和中西亚暖温带干燥气候区,这2类气候区均无甘肃样点;次适宜区1类,即热量条件适宜而干燥条件不足的甘肃南部暖温带武都等4个样点;边缘区1类,即热量条件适宜而生长季节湿度较高的温带半湿润气候区的甘谷等4个样点和干燥与光照条件好而热量不足的温带干旱半干旱气候区的敦煌等4个样点;不适宜区1类,即光热水资源均不足的部分温带、寒温带区域的迭部等10个样点。

Cultural Regionalization of Introduced Pistachio in Gansu Province

In order to effectively develop introduction and cultivation of pistachio in Gansu Province,comprehensive analysis of climate factors have been carried out at 30 selected sample plots,including 22 sample plots in Gansu Province,2 sample plots in Xinjiang,and 6 sample plots in other main pistachio culture countries. The results showed that according to temperature,heat quantity,precipitation and light conditions,the studied 30 sample plots could be divided into 4 climate types.There were two types of suitable regions,including Mediterranean climate and central-western Asia warm temperature arid climate,and all sample plots in Gansu Province were not of the two climate types.There was one type of Sub-suitable region,which had adequate heat quantity and too humid(4 sample plots).There was one type of marginal region,moderate temperature semi-humid climate(4 sample plots) or moderate temperature arid or semi-arid climate(4 sample plots),which had adequate heat quantity and was too humid at growth period,or had adequate humidity and less heat quantity.There was one type of unsuitable region,cold temperature arid or semi-humid climate(10 sample plots).
