摘要
大蒜连作障碍已成为制约其产量和品质的关键因素。现从土壤养分元素不均衡、化感物质积累、土壤微生物区系变化的角度阐述了大蒜连作障碍产生的机制,并介绍了克服连作障碍产生的各项防治措施,同时对研究大蒜连作障碍领域所存在的问题和研究方向进行了展望。
The continuous cropping obstacle of garlic has become the key factor of restricting the yield and quality.The mechanism of continuous cropping obstacle was elaborated in soil nutrient unbalance,accumulation of allelopathic substances,and change of soil microbial flora.The prevention and control measures were introducted to overcome the continuous cropping obstacle.The main problems and research orientation were also put forward on the continuous cropping obstacle of garlic in this paper.
