摘要
目前设施蔬菜生产中存在水资源浪费和施肥过多等问题,造成了资源与环境的损耗,蔬菜产量和品质下降。水肥耦合技术可以有效缓解这一难题。结合近年来水肥耦合在蔬菜生产中的应用研究,分析了水肥耦合对设施蔬菜生长发育、产量、品质以及土壤环境和养分利用效率的影响,旨为系统阐述水肥因素之间的耦合机理,正确应用水肥之间的协同效应,实现水肥利用效率以及蔬菜产量和品质的同步提高。
At present,there are some problems of waste of water resources and excessive fertilization in vegetable production,resulting in loss of resources and environment,and vegetable yield and quality.Water and fertilizer coupling technology can effectively alleviate this problem.Combining with the research on the application of water and fertilizer coupling in vegetable production in recent years,the effects of water and fertilizer coupling on the growth,yield,quality,soil environment and nutrient utilization efficiency of facility vegetables were analyzed,the coupling mechanism between water and fertilizer factors was systematically expounded,so as to correctly apply the synergistic effect between water and fertilizer,and improve the water and fertilizer utilization efficiency as well as the yield and quality of vegetables.
