| 摘 要： | 近些年来，沙棘木蠹蛾大面积成灾，作者调查发现，沟底、水库边及河滩沙棘林有极强的抗灾能力.为进一步探索研究这种现象及其机理，从2001年起，作者分别在内蒙古自治区鄂尔多斯市及辽宁省建平县的虫灾区，进行了为期6年的观测与研究. 结果表明，影响沙棘抗沙棘木蠹蛾的主导因素不是土壤肥力，而是土壤水分；水肥充足，使沙棘光合作用增强，蛋白质、贮藏营养物质增加，糖等有机化合物减少，碳氮比值下降，Na+、K+含量比率失调，树体体温下降；河滩沙棘林的抗虫机理，是由土壤含水量诱发的一系列抗生因素综合作用的结果.

| Abstract: | Holcocerus hippophaecolus exists in many areas and has become serious disaster in recent years.In order to expound and research this phenomenon and its mechanism further,six years' observation and research were carried out in the pest disaster regions of Ordos City,Inner Mongolia and Jianping County,Liaoning Province separately from year 2001.Investigation revealed that Hippophae rhamnoides growing in ditch,reservoir and flood land had strong power to resist the disaster.Six years of observation and research show that the factor influencing the resistance of H.rhamnoides to H.hippophaecolus is not the soil fertility but the soil moisture.Adequate water and fertilizer can enhance photosynthesis and the stocks of protein and other nutrients,also can reduce sugar and other simple compounds,C/N ratio decline,Na~ /K~ ratio imbalance and the body temperature of tree drops.The results indicate that the resistance mechanism is the combined results of a series of antibiotic factors,which are induced by soil moisture. |
