喷灌条件下花生水肥耦合效应的田间试验研究

水肥是影响作物产量的两个重要因子，合理的灌溉与施肥是作物增产的主要途径。通过采用喷灌灌水技术，对花生水肥耦合效应进行田间试验研究，探讨了不同灌水施肥处理对花生产量、耗水规律、氮素运移等的影响，建立了反映花生产量与施肥量、灌水量关系的数学表达式，提出了喷灌条件下花生不同生育期适宜的灌水计划湿润层深度。

Experiment on the Coupling Effect of Water and Fertilizer for Peanut Under Sprinkler Irrigation

Water and fertilizer are two important factors that affect crop yield. Proper irrigation and fertilization is the main method to increase production. A field study on the coupling effect of water and fertilizer for peanut by adopting sprinkler irrigation was carried out. The different irrigation and fertilizer treatments that affect the yield of peanut, water consumption and nitrogen transportation were discussed. A mathematical formula that reflects the relationship between the yield of peanut and the amount of irrigation and fertilizer was established. A suitable plan irrigation moisture layer depth was also presented.
