【摘要】 为消除秸秆还田的负面影响,改善土壤性状,以不处理为对照,研究了高温闷棚、常规强还原、强还原秸秆还田、氯化苦熏蒸、灌水洗盐等处理对设施盐渍化土壤理化性状及辣椒(Capsicum annuum L.)生长的影响。结果表明,相比其他处理,强还原秸秆还田处理土壤EC值最低,返盐更少;灭杀病原菌效果好,不用化学药品,病害发生率更低;促进了辣椒根系和植株的生长,辣椒产量最高,缺株率最低,生产上安全性高。更多还原

【Abstract】 In order to eliminate the negative effects of straw returning to the field and improve the soil properties,this study used pepper(Capsicum annuum L.)as a crop and facility continuous cropping soil as the treatment object,the experiment used no treatment as a control,and studied the high temperature stuffy shed,conventional strong reduction,strong reduction straw returning to the field,chemical effects of trichloronitromethane fumigation and flooding on physical and chemical properties of facility salinized soil and the growth of pepper. The results showed that,compared with other treatments,the strong reduction straw returning treatment reduced the soil EC value to the lowest,with less salt return. The effect of killing pathogenic bacteria is good,no chemicals are needed. The incidence of diseases is lower;the growth of pepper roots and plants is promoted. The yield of the pepper is the highest,the rate of missing plants is the lowest,and production safety is higher.更多还原
