喷灌条件下花生玉米间作的水肥耦合效应

Coupling Effect of Water and Fertilizer on Intercrop of Peanut and Maize With Sprinkler Irrigation

对喷灌条件下花生玉米间套种植模式中的水肥耦合效应进行了田间试验研究。结果表明：花生的主要耗水阶段是开花至结荚期，玉米是抽雄至成熟期；从全生育期来看，耗水量及水分生产效率均随施肥量的增加而增大。

Field experiments on the coupling effect of water and fertilizer on the intercrop ofpeanut and maize with sprinkler irrigation have been conducted. The results show that thecritical growing of water consumption is from flowering to podding for peanut while silkingto maturity for maize. During the whole growing season, the water consumption and thewater-production rate are increased with the more fertilizer used.
