| 摘 要： | 采用4因素饱和设计,定位研究了农家肥、麦草、氮、磷化肥配施对旱地小麦土壤水分生产效率的影响,并建立了相应的数学模型.结果表明,在相同降水条件下,通过不同的施肥措施,可使旱地小麦土壤水分生产效率提高3倍以上.4种肥料对土壤水分生产效率影响的顺序为;氮肥>农家肥>磷肥>麦草.其中农家肥和氮肥是正效应,麦草和磷肥呈负效应;各肥料间尚有一定的交互效应.当前提高羊地小麦水分生产效率的较好的肥料结构为:农家肥7500kg/亩,氮肥12.5 kg/亩,磷肥2～5kg/亩,不施用麦草.

| Abstract: | The effects of four factor including farm manure, wheat-straw,N and P fertilizer application or soil water production efficiency of dryland wheat by saturated designed field experiments were studied and 2 set of mathematical model were put forward by statistical analysis with computer.experimental result showed that soil water production efficiency of dryland wheat was increased try three-fold wilt different fertilizer application.The sequence of effect of four fertilizer on soil water production efficiency was N fertilizer>fasm manure>P fertilizers wheat-straw.Among those factor farm manure and nitrogenous fertiliser were positive effects, wheat-stiaw and phosphate fertilizer were nogative effcts.Now better fertilizer structure to raise soil water production efficiency of dryland wheat can be marked out and isled below.,farm menure is 7500kg/mu, Nitrogenous fertilizer is 12.5 kg/mu, phosphate fertilizer is 2-5 kg/mu,wheat-straw can not be applied. |
