摘要: |
大蒜是我国重要的经济作物,大蒜连作障碍是制约其产量和品质的关键因素。本文从连作障碍对大蒜生长的影响入手,通过阐述大蒜土壤微生物群落失衡、土壤养分不均衡、自毒作用及各因素相互关系等,解析大蒜连作障碍形成的机理机制。同时,对目前大蒜生产中常用的,防治连作障碍的手段进行分析,最后对大蒜连作障碍研究方向做出展望。 |

Abstract: |
Garlic is an important economic crop in China.Continuous cropping obstacle is a key factor to restrict garlic yield and quality.We review the effect of continuous cropping obstacle on garlic growth in this paper.The mechanisms of garlic continuous cropping obstacle are analyzed by expounding garlic soil microbial community imbalance,soil nutrient imbalance,autotoxicity and the relationship among various factors.The common measures and prospects for the prevention and control of continuous cropping obstacle of garlic are introduced. |
Key words: garlic continuous cropping obstacle garlic soil microbial community imbalance soil nutrient imbalance autotoxicity prevention measure |
