连作导致花生产量降低、品质下降,连作障碍已成为我国花生产业发展面临的突出问题。从土壤营养元素失衡、化感物质的自毒作用和微生物区系失衡三个方面综述了花生连作障碍的发生机理,认为花生连作障碍发生的主要原因是根系土壤微生态系统功能失调。从多因素相互作用角度出发,提出关键因子的挖掘是花生连作障碍机制研究的有效途径。
Research Progress of Soil Microenvironment and Peanut Continuous Cropping Obstacle Mechanism
Continuous cropping leads to the yield reduction of peanut and the decline of quality; continuous cropping obstacle has become a prominent problem for peanut industry development in China at present.In this research, the occurrence mechanism of peanut continuous cropping obstacle was reviewed from three aspects of soil nutrient imbalance, toxic effect of allelochemicals, and microflora imbalance.It was pointed out that the root soil microecosystem function disorder was the major cause of peanut continuous cropping obstacle occurrence .From the perspective of multifactor interaction, the mining of key factor was the effective way to research the mechanism of peanut continuous crop-ping obstacle.
