摘要
综述了引起花生连作障碍的因素,如土壤微生物群落失衡、酶活性降低、土壤养分比例失调、营养元素供应不足、根系分泌的有机酸的积累以及田间病虫害发生几率的增加等。介绍了目前花生连作障碍的主要防治措施,如改良耕地、轮作换茬、合理选择肥料、选用耐重茬品种、土壤消毒等方法。
The article summarizes some elementary factors causing soil-borne diseases of peanut after continuous cropping,including unbalance of soil microbial population,decrease of soil enzyme activities,unsuitable ratios of soil nutrients,deficient nutrient elements supply,accumulation of organic acids secreted by peanut root system,and accumulative increase of pathogens in the soil,and introduces the main measures to control soil-borne diseases in continuously-cultivated peanut at present,such as improving cultivated land,rotative cropping,proper application of fertilizers,screening and cultivation of superior peanut varieties tolerant to soil-borne diseases,and soil disinfection.
