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.
