Abstract
By using of three-factor,quadratic regression rotation composite design,the Relation between resource and sinks of Chinese hybrid rice under dry cultivation were studied in Nigeria.The results indicated that in filling milk period these three factors (nitrogen application,Nitrogen Fertilization Strategy,density of spot seeding) markedly influence LAI( leaf area index ),quantities of colony glume-flowers,quantities of truth grain,yield,and ration of grain/leaves.It may preferably control the LAI at heading period in a suitable range and delay the decreasing of LAI at filling milk period under a design which had the suitable nitrogen applied,nitrogen fertilization strategy and density of spot seeding.This design ensured enough photosynthetic leaves and increased amount of glume-flowers and ratio of grain/leaves acreage.Therefore,a high yield colony was come into being due to the more photosynthate was needed to links and the speed of assimilative matter from source to links was improved.
