Drought-prevention,Drought-resistance and Rescue under Emergency for Agriculture in Plain-lake Region in Hubei Province

Abstract：Regional drought from the winter last year to this spring to be regarded as a research background,based upon general and representative investigations,this paper through analysis considers that little rain and aridity resulted in different influences respectively on rape,winter wheat,cotton as well as vegetables cultivated in the open;in the plain-lake region,the yield of winter wheat generally increases and decreases merely in a few localities,rape at large is reduction of output,early rice and aquiculture were affected severely due to drought.In light of influence of the drought on agriculture since March,this paper put forward water conservancy measures and adjustment-control measures of water and fertilizer,meanwhile some concrete methods to cope with drought were put forward aiming at middle rice,cotton,vegetables and aquiculture.Considering the actuality of frequent water-logging disaster and coexistence of drought and water-logging in the region,some suggestions in viewpoint of disaster control and reduction were given that are： control both drought and water-logging must be considered,it is needed to establish a water resources system that is characterized by control both drought and water-logging,diversion works combing with pumping works,combination of water storage and drainage,and water release from drainage system utilized again as irrigation water in some cases,so that disaster from drought and water-logging is solved efficiently;carrying out a research on cultivated technology and its system that focus on control drought and water-logging for staple crops,carrying through a research on planting technology and its system that is water storage combing with drainage and has an ability to control drought,which is suitable for those cropland where landform is higher;energetically boosting high effective plantation and aquiculture that may be water-saving,so as to provide scientific support for agricultural sustainable development.
