Extension Research For Garden Green Plant Protection Technology Of City Group Of Shandong Peninsula

With the improvement of life quality and the enhancement of environmental protection awareness, the construction of high-grade urban garden green fields, landscaping, greening, environmental protection and sustainable development have become a consensus idea. However, many sorts of harmful organisms invasion were often happened during the landscape maintenance and management, resulting in yellow leaves, withered branches, undergrowth. These diseases greatly reduced the garden greening and ornamental effects. Spraying of traditional chemical pesticides could kill the natural enemies, but meanwhile pollute the environment, and further easily to cause human and animal poisoning, and make the harmful organisms produce resistance. The abuse of agricultural chemicals is more and more serious. Taking ecological control technology in the construction of urban garden green space, that is, to adapt the ecological system which is composed of garden plants, harmful organisms and environment, can realize the sustainable control of urban landscapes.By selecting some plants in public green spaces of city groups in Shandong peninsula, a comprehensive investigation into the types, occurrence time, damage, prevention and treatment of what happens to the botanical garden plant diseases and insect pests was carried out. Further more, our aims included the collection and identification of organisms in details. A total of 134 species of insect pests had been found, including 62 kinds of defoliator,45 kinds of suck juice insects,22 kinds of wood-borer and 5 kinds of soil insect. And a total of 41 species of diseases had been found, including 24 kinds of leaf disease,9 kinds of branches diseases,5 kinds of root diseases and 3 kinds of other diseases. There are more than 3000 specimen collection and 16000 digital photos during the investigation. The basic situation of botanical garden plant diseases and insect pests in the city groups in Shandong peninsula area was clarified. The treatments for protecting plants in the city groups in Shandong peninsula area was deeply discussed combined with the existing problems, in order to explore a set of suitable plans for protection technology solutions which is applicable to the characteristics of the city group of Shandong peninsula area garden green plants.
