| Abstract: | This paper evaluated the fertilizer response to barley(Yanfu'aizao No.3)in hilly region of middle Sichuan by using systimatic analysis methodbased on field experiments.The results indicated that to controll the num-bers of the effective ears per hectare was the major means to adjust thefunction of the barley production system.The controlling equations ofthe relations among the sizes of the barley system of different growthstages,the yield-compositive factors and the fertilizer application amou-nts of N,P and K were established,the function of the barly system wasalso simulated.Some sets of the proper populations of the system andtheir corresponsive amounts and ratioes of N,P,K fertilizers applicationwere recommended.Thesesets could be used in hilly region of middle Si-chuan. |
