设施栽培已成为我国重要的蔬菜生产方式之一。近年来,全国各地设施栽培面积发展很快,然而,由于重茬连作和盲目大量施用化肥等不当的农业措施,导致温室土壤质量退化、养分失衡、盐渍化严重,从而导致设施蔬菜产量和品质下降。特别是近年来化学肥料的施用量越来越大,使得设施土壤与露地土壤生态环境有明显的差异。而且设施土壤利用到一定年限后,土壤的理化性状将发生变化,主要表现为土壤酸化,
Facility cultivation has become one of the important vegetable production modes in our country. In recent years, the cultivated area of facilities in all parts of the country has been developing rapidly. However, due to unreasonable agricultural measures such as continuous cropping and blind and large-scale application of chemical fertilizers, soil quality degradation, nutrient imbalance and salinization in the greenhouse have been severely impaired, . Especially in recent years, the application of chemical fertilizers is increasing, making the facility soil and open soil ecological environment have obvious differences. And the use of facilities to a certain period of soil, soil physical and chemical properties will change, mainly as soil acidification,
