| 摘 要： | 经过易地栽培、嫁接试验、探索性防治试验及元素分析和施肥诊断等手段,证明了发生在福建省寿宁县黄山松苗针叶“紫色病”是一种由于缺镁引起的生理性病害。对不同地方土壤、气候等环境因子进行相关分析。结果表明:土壤质地较轻,有机质含量少的酸性土壤容易发病,发病季节的高温、干旱使病害发生更加严重。苗木根冠比测定结果表明较低的根冠比与黄山松苗缺镁症有较密切关系;并提出土壤改良的具体措施。

| Abstract: | The disease of Pinus taiwanesis familiarly known as "violet disease" is found in Shouning,Fujian Province.It has been proved to be a physiological disease caused by Magnesium deficiency by means of transplantation,grafting,exploratory control,element analysis and fertilization diagnosis.The analysis of the factors such as soil,climate in different nursery shows that the disease develops easily in the acid,light soils with low magnesium contents.High temperature and drought can aggravate the disease all the more.The root-shoot ratio measurement shows that the diseased plant has low root-shoot ratio,which has concern with inner magnesium deficiency in the seedling growing of Pinus taiwansis.The methods to ameliorate soil are given |
