滴灌条件下水肥耦合对水果产量及品质影响的研究进展

我国是果业大国,但是果业生产中普遍存在着不科学的水肥管理,导致灌溉水的浪费和肥料的流失,更加剧了农业生态环境的污染。这也正是我国并未成为水果强国的重要原因。如何利用先进的灌溉技术,以有限的水肥投入促进水果生产,并达到节水节肥、优质丰产、高效环保目的,是现代农业节水领域迫切需要解决的关键问题。该研究讨论了水肥耦合的概念以及滴灌条件下水肥耦合对水果产量、品质的影响和对产量的模拟研究现状,并且对今后的研究进行了展望。

Research Progress of Fertilizer and Water Coupling on Fruit Crops Yield and Quality under Drip Irrigation

China is a big country on fruit industry,but the prevalence of the unscientific water and fertilizer management in fruit production results in the loss of irrigation water and fertilizer and exacerbates the pollution of agricultural ecological environment,which is the important reason why our country does not become a large fruit country. How to use advanced irrigation techniques to promote fruit production by the limited water and fertilizer and achieve the goal of water and fertilizer conservation,good quality and high yield and efficient environmental protection,is the key scientific problem of modern agricultural water conservation area needed to be addressed urgently. This article discusses the concept of water and fertilizer coupling,the effect of water and fertilizer coupling on fruit yield,quality and water and fertilizer use efficiency under drip irrigation,and the status of simulation research of yield,and the prospects to the further research are put forward.
