四川江油市附子地土壤pH研究

Study on the Soil pH of Aconitum carmichaeli Dexb.Cropping in Jiangyou,Sichuan Province

[目的]明确四川江油市附子道地产区土壤酸化情况.[方法]对江油市附子道地产区48个附子地土壤pH进行了研究。[结果]48个附子地土壤pH在3，89-6．40之间，其中pH仅为4．00～5．00的土壤样品数占总样品数的62．50％。[结论]江油附子道地产区土壤酸化严重，亟需深入研究其原因并制定合理的防治措施。

[Objective] This study aimed to explore the situation of soil acidification of A conitum carmichaeli Dexb. cropping in Jiangyou, Sichuan province. [Method] Soil pH of 48 cropping fields distributing among the studied area had been measured. [Result] The results showed that the field soil pH was between 3.89 to 6.40. The number of soil samples with pH from 4.00 to 5.00 accounted for 62.50% of the total number of samples. [Conclusion] The results indicated that the problem of soil acidification was very serious. It needs to further explore the influence factors of soil acidification and make related mitigation measures.
