摘　　要：[目的]探讨花生和谷子间作条件下水肥运筹对作物产量的影响。[方法]采用水、氮、磷"3414"试验设计,研究间作条件下不同水肥处理对花生和谷子产量的作用效果。[结果]间作条件下花生和谷子产量对水肥的响应较为一致,土壤水分养分与花生产量相关性由强至弱依次为土壤水分>氮施用量>磷施用量,与谷子产量相关性由强至弱依次为土壤水分>磷施用量>氮施用量。水、氮、磷三因素合理配施能够降低水肥投入量,提高水肥利用效率。花生谷子间作条件下,适宜土壤含水量均较低,可在大部分半干旱地区雨养种植。各因素之间,磷肥与水的耦合作用>肥料之间的耦合作用>氮肥与水的耦合作用。间作条件下,花生适宜的土壤含水量为占田间持水量的57.3%,适宜的氮素和磷素施用量分别为0.49 g/盆和0.2 g/盆,谷子适宜的土壤含水量为占田间持水量的59.1%,适宜的氮素和磷素施用量分别为0.29 g/盆和0.23 g/盆。[结论]研究结果为该种种植模式的应用和推广提供理论和技术参考。[Objective] The aim was to explore the effect on vieh[ under different water and nutrient t＇ollditiolls in peanut and ]oxtail millet intereropping. [Method] Following tile ＂3414＂ design of water, nflrngen, and phosphorus, the yield of peanut-millel intereropping under difI＇erent conditions of water and fertilizer in soil were investigated. [Result] The resuhs showed that peanut and fl）xtail millet yield response of water and fertilizer were consistent under the condition of inlen＇ropping, and the correlation soil moisture and nutrient for peanut yieht related degree： soil moisture〉nitrogen〉phosphate： the correlation soil moistm＇e and nutrient for ]oxtail millet yield related degree： soil moisture〉phosphate〉nitrogen. Water was the most important ]actor to aft^ct crop yields and optimum soil moisture was lower under the conditions o]＂ peanut-and-millet intercropping. Tiros, peanut-and-millet intereropping was generally able to fit most of the semi-arid region. In the interaction of various factors, the enupling effect of water anti phosphorus was stronger than the coupling effect of fertilizers, ]bllnwing l,y the coupling effect of water and nitrogen. When other factors were in rich level, both of the optimal value fl,r single faetors of water, nitrogen, and phosphorus and the optimal value for twofactor interactions of water-nitrogen, water-phosphorus, and nitrogen-phosphorus, were higher than the optimal value ibr the interaction of water, nitrogen, and phosphorus. Under the condition of water-nitrogen-phosphorus interaction, the soil moisture content optimal for peanut accounted for 57.3% of the field capacity, and the related appropriate application rates of nitrogen and phosphorus were 0.98 g/pot and 0.39 g/pot, respectively. Likewise, the soil moisture content optimal for millet was 59.1% of the field capacity, and the counterpart appropriate application rates of nitrogen and phosphorus were 0.57 g/pot and 0.45 g/pot. [Conclusion] The results provided a reference and basis for la
