| 摘 要： | 设施土壤长期连作导致的真菌病害发生与土壤理化性状变化密切相关,施用碱性土壤改良剂可以减轻设施酸化土壤上土传病害的危害。以黄瓜连作25 a的设施土壤为供试土壤,通过盆栽试验比较施用2.5 g · kg~(-1)腐植酸钾(pH 8.5)和硅钙钾镁肥(pH 9.96)两种碱性土壤改良剂对盆栽黄瓜生长及枯萎病的防治效果。结果表明:施用腐植酸钾和硅钙钾镁肥后,土壤pH比不施用改良剂的对照显著提高0.10和0.24个单位,促进了黄瓜幼苗生长,对黄瓜枯萎病的防治效果分别达到45.8%和51.3%,显著提高了土壤交换性钾含量。与腐植酸钾相比,硅钙钾镁肥的促生和抑病效果较显著。

| Abstract: | The occurrence of fungal diseases induced by continuous cropping in protected field was closely
related to the changes in soil physichemical properties．Applying alkaline soil ameliorant could reduce the
damage of soil-borne diseases in protected fields of acidified soil．Taking protected field soil with 25 years’
continuous cropping on cucumber as test soil，and through pot experiment，this study compared the effects
of 2 kinds alkaline soil ameliorant，including 2.5 g · kg-1 of potassium humate（pH 8.5，HA）and fertilizer
of calcium silicon magnesium potassium（pH 9.96，SiCa）on cucumber growth and controlling Fusarium
wilt．The results showed that these 2 kinds of ameliorant，HA and SiCa had remarkbly increased the soil
pH by 0.10 and 0.24 unit，respectively，comparing with no application of ameliorant treatment；promoted
cucumber seedling growth；the effects of controlling cucumber Fusarium wilt had reached 45.8% and 51.3%，
respectively．Application of these 2 ameliorants had also significantly improved the soil exchangeable
potassium contents．Compared with HA，SiCa performed more outstanding effects in promoting cucumber
growth and inhibiting cucumber Fusarium wilt． |
