甘肃文县花椒栽培区划研究

花椒是典型的耐寒、抗旱、喜温、喜光、喜肥、好气树种，甘肃文县全境光热水资源丰富，尤其东南部光热水资源优于西北部，但从生产实际反应，花椒在该县东南部的生长结实状况不及西北部。通过2005-2007年对该县10个调查点、100个样株定向观测，采取各调查点主导气象、土壤因子与花椒产量相关分析方法，得出年降水量是影响该县花椒分布的最重要因子，并以年降水量为依据，对甘肃文县花椒栽培作了区划。

Study on Distribution and Planting Division of Zanthoxylum bungeanum in Wen County of Gansu Province

Zanthoxylum bungeanum is a typically tree species with characteristics including cold-resistance,drought-resistance,thermophilic,light-loving,fertilizer-loving and aerobic,there are abundant in sunlight,heat,and water resource in Wen county of Gansu province,especially the resources in the southeast are more sufficient than that in the northwest,however,the practical production showed that the growth and fruiting of Zanthoxylum bungeanum in the southeast are interior to that in the northwest.By the oriented observation of one hundred samples and ten plant spots in the county from 2005 to 2007,through correlation analysis between meteorology soil and production,the results showed that annual precipitation is the most important factor,which affects distribution of Zanthoxylum bungeanum in the county,moreover,planting division of Zanthoxylum bungeanum has been made based on annual precipitation in Wen county of Gansu province.
