| 摘 要： | 本研究旨在明确3种腐植酸类物质(NaFA、KFA、CFA)及与新药肥(SY)复配物对温室黄瓜根际植物线虫数量是否有抑制作用.研究结果表明:(1)矮化线虫属Tylenchorhynchus和根结线虫属Meloidogyne是2种主要的植物线虫,(2)随着生长季后期植物线虫数量的迅速增长,5种腐植酸类物质(CFA、NaFA、KFA、OFA SY、NaFA SY)及SY防治区矮化线虫和根结线虫数量低于对照区,(3)CFA与新药肥SY复配效果强于OFA和SY的单一作用效果.

| Abstract: | The effect of three kinds of humic substance(NaFA, KFA, CFA) and the combinations(CFA SY, NaFA SY) on inhibiting plant parasitic nematodes of cucumber was studied in the greenhouse. The results showed that: (1) The genus of Tylenchorhynchus and Meloidogyne were mainly plant parasitic nematodes; (2) In the late growing season, the nematode population obviously increased, while population density of stunt nematode and root-rot nematode were lower in five kinds of humic substance treatments(CFA, NaFA, KFA, CFA SY, NaFA SY) and SY treatment than CK; (3) The inhibiting effect of combinations of CFA and SY was more significant than that of CFA and SY singly. |
