5.RESEARCH ON MECHANISM OF STEM BRUSH OF AZODRIN TO CONTROL PESTS IN PLANE TREE
6.The resistance of chinar, hawthorn and ural falses piraea are relatively low, which maybe bring problems.
7.The order of the BCR values of these four species in 2004 was Platanus spp. (8.107) > Ficus concinna (2.579) > Ginkgo biloba (1.543) > Grevillea robusta (1.055).
8.Some simulated re-sults are shown in this paper on azodrin content in plant tree by means of expri-ments and recognization of model parameters.
9.Azodrin content in plane tree was determined after stem brush and trunk injection, on the basis of which the grey dynamic model was established to describe the dynamic distribution of azodrin in the tree, A discussion was followed about what and how to have an influence on it.
10.These characteristics have the similarty of Meloidogyne platani in the description of root- knot nematode on American planetree made by Hedwig Hirschmann in 1982. So we have identified that root-knot nematode of London planetree in Qingdao belongs to Meloidogyne plantani Hirschmann.
