Abstract
Based on long-term statistical data provided by specific department in Xinxian g region of Henan province,it is showed that the main factors related with agric ultural eco-environment have changed greatly in recent decades.For example,annu al sunshine hours and annual average wind speed decreased gradually,while the re lative humidity increased slowly with time,which caused regional decrease of eva poration from water surface.Moreover,some plant diseases and insect pests are be coming more serious than ever owing to the changed meteorological factors,the de velopment of irrigation system and the increased N application rate.Effective me asurements for lessening the danger of plant diseases and insect pests are to es tablish water-saving agriculture and economic fertilization systems and to evol ve new varieties with high pest resistance.关键词
