渭北旱原不同水肥配比冬小麦根系效应的研究

Research on Responses of Winter Wheat Root System to Different Soil Water and Fertilizer Application on Weibei Rainfed Highland

根据渭北旱原合阳旱棚箱栽试验的冬小麦根重结果，建立了根重与水肥的回归方程。通过回归方程的主因素分析得出各因素对冬小麦根重的影响顺序为土壤含水量＞Ｐ＞Ｎ。

The regression equation among root weight,fertilizer and soil water was established on the basis of the results of winter wheat root weight through the rainfed box planting experiments in Heyang County on Weibei Rainfed Highland.The effect order of each factor obtained from the analysis of major factors of regression equation upon winter wheat root weight was soil water>P>N.Also,the responses of winter wheat to different soil water and fertilizer applications upon root weight is also analysed on Weibei Rainfed Highland comprehensively.
