克服蔬菜作物连作障碍问题之研究进展

蔬菜作物连作障碍是蔬菜生产持续发展所面临的一个重要问题，通过查阅有关克服蔬菜连作障碍的研究报告，结合作者从事相关研究的结论和进展，就蔬菜作物连作障碍产生的原因和克服的途径进行综述，以便为相关研究和类似技术的实际应用提供借鉴。大量的研究表明，引起蔬菜作物连作障碍的主要原因有土壤中有害微生物的积累、土壤的次生盐渍化、蔬菜作物的自毒作用等。通过轮作、间作套种、生物防治、选育抗重茬品种、嫁接栽培、增施有机肥等措施可以部分或全部解决蔬菜作物的连作障碍问题。

Review on Continuous Cropping Obstacle in Vegetable Crops

The continuous cropping obstacle of vegetable crops is an important problem in vegetable production. By means of review to the relative research paper in continuous cropping obstacle of vegetable crops, the aim of this paper is to supply information to the research and application in this field. A lot of research results showed that the main causes of continuous cropping obstacle are accumulation of harmful microbes, salinization of soil, auto-toxicity of vegetable crops etc. Many research results showed that the continuous cropping obstacle could be resolved completely or partly by means of crop rotation, intercrop, bio-control, using resistant varieties, grafting, and organic fertilizer etc.
