水肥耦合对南瓜生长及产量的影响研究进展

传统的灌水、施肥方式不仅水肥利用率低、浪费人工和成本，而且污染农田环境。水肥耦合技术通过对灌水与施肥合理的配比来达到提高水肥利用效率、产量、品质及降低生产成本的目的。本文主要综述了水肥耦合调控对南瓜的生长发育过程、光合作用、产量及品质的影响。结果表明，合理的水肥调控能显著促进南瓜生长发育及光合作用，对干物质积累有积极作用，提高了南瓜的产量与品质。最后对水肥耦合技术在农业生产中的推广与应用进行了展望。

Research progress on the effect of water and fertilizer coupling on the growth and yield of pumpkin

The Traditional irrigation and fertilization methods not only have low water and fertilizer utilization rates, waste labor and costs, but also pollute the agricultural environment. The coupling technology of water and fertilizer achieves the goal of improving water and fertilizer utilization efficiency, yield, quality, and reducing production costs through a reasonable ratio of irrigation and fertilization. This article mainly reviews the effects of water fertilizer coupling regulation on the growth and development process, photosynthesis, yield, and quality of pumpkin. The results showed that reasonable water and fertilizer regulation can significantly promote the growth, development, and photosynthesis of pumpkin, have a positive effect on dry matter accumulation, and improve the yield and quality of pumpkin. Finally, the promotion and application of water fertilizer coupling technology in agricultural production were prospected.
