设施蔬菜连作障碍的研究进展

Research Advances in Effect of Continuous Cropping Obstacles on Facility Vegetable

连作障碍已成为我国设施蔬菜发展的技术瓶颈。该文从土壤理化性质、土壤养分、土壤微生物、土壤酶活性及作物自毒作用等方面综述了设施蔬菜连作障碍产生的机理,并提出了相应的防治措施。

Continuous cropping obstacles has become the bottleneck of the development of facilities vegetable. This paper an- alyzes the mechanism of vegetable continuous cropping obstacles, from the physical and chemical properties of soil, soil nu- trient, soil microorganism, soil enzyme activity and crop autotoxieity, and puts forward the corresponding prevention and control measures.
