| 摘 要： | 对安徽农业大学实验林场湿地松枯死原因的调查研究结果表明,造成树木枯死的原因是多方面因素共同作用的结果,是一种林木衰退病。其衰退枯死的原因为:①诱发因素:温度年较差较大,降雨量分布不均匀,土壤粘重板结,管理不善;②激化因素:干旱,雨季积水;③促进因素:松枯梢病菌、根腐病菌、立木腐朽病菌,天牛、小蠹虫等次生性病虫害的危害。

| Abstract: | Investigation of the causes of wilt and dying of Pinus elliottii in the experimental forest farm of Anhui Agricultural University was carried out.The results showed that the cause of disease might develop from many factors.The first group of factor was high and low temperature,rainfall and excessive soil bulk density.The second group of factor was severe drought and excessive soil moisture.The last group of factor was several biotic agents such as shoot blight infected by Sphaeropsis sapinea,decay wood and root rot by fungi,bark beetles and wood borer. |
