摘要:
瘿瘤病是浙江天目山国家级自然保护区柳杉(Cryptomeria Fortunei)上一种非常严重的病害. 为了探究天目山柳杉瘿瘤病的有效防治方法,本研究运用施生石灰处理柳杉生长土壤的方法,通过测定2017年3月和2017年10月(间隔期8个月)柳杉样本瘿瘤的大小与密度、土壤pH值、土壤营养元素含量、新梢生长量、相对叶绿素含量、新叶的叶绿素荧光参数等指标,探讨施生石灰法对柳杉瘿瘤病的防治效果. 结果表明,每m2施加20 g生石灰组比每m2施加50 g生石灰组处理对于控制柳杉瘿瘤病更为有效. 其中每m2施加20 g生石灰组处理能够显著提高土壤pH值,且能够使瘿瘤直径和瘿瘤密度分别下降19.3%、35.6%,同时显著提高土壤营养元素中亚硝酸还原酶的含量(P<0.05). 但对柳杉新梢生长的促进、柳杉相对叶绿素含量以及柳杉的PSII最大的或潜在的量子效率作用并不显著(P>0.05). 因此,施生石灰处理柳杉生长土壤的方法对防治天目山柳杉瘿瘤病有一定的防治效果.
Abstract:
Gall disease is a very serious disease on Cryptomeria fortunei in Zhejiang Tianmu Mountain national nature reserve. In order to explore the effective prevention and control of Japanese cedar gall disease method,this study using the method of quicklime processing fortunei soil by measuring in March 2017 and October 2017(interval 8 months)Japanese cedar sample size and the density of gallae,soil pH,soil nutrient content,new shoots,relative indices such as chlorophyll content,the chlorophyll fluorescence parameters of leaves grow,discussion of quicklime method of Japanese cedar gall disease prevention and cure effect. The results showed that the treatment of 20 g of quicklime per m2 was more effective than that of 50 g of quicklime per m2. Among them,20 g of quicklime group treatment for every m2 can significantly improve the soil pH value. The gall diameter and the gall density were decreased by 19.3% and 35.6% respectively. At the same time,the content of soil nutrient element nitrite reductase was significantly increased(P<0.05). However,the effects on the growth promotion of new shoots,the relative chlorophyll content of cryptomeria fortunei and the maximum or potential quantum efficiency of the PSII of cryptomeria fortunei were not significant(P>0.05). Therefore,the method of treating the growth soil of cryptomeria fortunei with quicklime has a certain effect on the prevention and treatment of cryptomeria fortunei Cecilia in tianmu mountain.
