摘要
根据田间试验资料,运用系统分析方法对川中丘区盐辐矮早三号大麦的肥料效应作了分析。结果表明,控制适当有效穗数是调控该大麦品种产量的主要手段。由此建立了大麦各生育期群体大小与氮、磷、钾施用量及产量构成要素间关系的控制方程,并对大麦生产系统的功能进行了模拟,得出了三套适用于川中丘陵区大麦的适宜群体结构及相应的氮、磷、钾肥用量和施用比例、
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.
