The Effects Of Garden Plants Configuration On Hyphantria Cunea

As scientific and technology develop and climate changes, some non-native introduction species have not only changed the structure of urban greening tree species composition, but also lead to the pests and dieases breaking out. Outbreak and broadcasting of the dieases and pests often have a close relation with their enviroment and always make plant grow badly, even make some plant death and species deteriorate,and lower vegetative quality,as a result,city’s horticlture has been damaged. therefore, it’s very important to controll dieases and pests. The mechanism of chemical influence play an important role among plants. We can grow beneficial plants to make good use of mechanism of cooperation coexistence and achieve the goal of repressing dieases and pests include Hyphantria cunea Drury.Through access to information and field surveys, the wild plants are mainly Tamarix, Central Asia, Atriplex, Chenopodium album, salsa, wild soybean, upright Astragalus, sweet clover, licorice, Chinese tamarisk, Apocynum, Artemisia scoparia, reed, Setaria viridis, Calamagrostis arundinacea, Cynodon dactylon and roe Mao in Dongying area. Through the efforts of several generations, Dongying area totally has the park plants have38families,68genuses, more than80species kinds, and formed a urban greening dominant tree species mainly with velutina, Ash, Chinaberry, poplar, willow, black locust and other forestry. The insect contains160genuses, which142genuses are the pest and others are beneficial insects, and the city area mainly has6orders,35genuses, the main taxa of Homoptera, Lepidoptera, Coleoptera, Hymenoptera, Hemiptera and Diptera6orders. Due to soil salinity and the difficulty of the plant introduction, plant single relative bear salt plant in large area, neglect ecology principle, unilateral pursue ecosystem efficiency and park view construction, result in the imbalance ecosystem, spreading plant diseases and pests, difficult to protection and management, particularly after the occuring webworm, most of the garden trees have been seriously damaged. Therefore, the study configuration of the fall webworm and other garden plants pest control has become an important issue facing the garden workers.Collect and observae Hyphantria cunea both indoor and outdoor make us know that Hyphantria cunea can undergo three generations among which two generations are compelted in DongYing. there are five kinds of plant include mulberry, Fraxinus velutina, Robinia pseudoacacia, poplar, weeping willow among eighteen damaged species by Hyphantria in DongYing. Less selectivity kinds include:elm, apple, grape, Ash, Bauhinia, Sophora japonica var.pendula, Ziye Li, Lagerstroemia, Malus micromalus and so on Hyphantria has no interest on bitter neem tree, cypress and so on. According to the study we Understand the application of Chinaberry velutina and its configuration with mulberry, application with elm trees and other bait plants. We also know how insect-resistant varieties selection and three configurations of the fall webworm effect Hyphantria cunea outbreak.According to the present situation in Dongying area, some plant configurations in saline-alkali soil area should be noted:1. Follow ecology regulation, plant trees in proper place; Joe, infuse and grass should be reasonable allocation, make use of the different adaptability and cooperation mechanism of various seedling wood, attain reformation and orientation salt such soil to obtain satisfied greening effect.2. Make use of an eco-compensation designthe and build complex layers garden to enhance plant diversity-building.3. Give full consideration to the major pests and diseases in local region, rationally use of the Allelopathy of plants and pests.4. choose anti-pest species and rational allocate plant species;5.make plant species localizationGive suggestions as follow:1) both government and enterprise establish the integrated management of landscape eco-system with public participation.2).configure urban garden plants scientificly;3) not only in suburbs but also in the city build eco-green recommendations.
