摘要: 以平顶海棠幼苗为试材,探讨5种不同果园土壤处理对苹果再植病害的影响.结果表明:经过日光高温消毒、溴甲烷熏蒸和福尔马林消毒处理均可极显著地降低海棠幼苗的死亡率.未经任何处理的果园土壤在海棠幼苗移植8周后导致67%的幼苗死亡.而空白对照死亡率为11%,从而确定16a生苹果园土壤对海棠幼苗的校正死亡率为62.5%.说明生物因素是造成苹果再植病害的重要原因.
英文摘要: Taking Bogonia seedling as test material,discussed 5 different orchard soil treatment on the influence of apple replant disease.The results showed that the mortality of the Begonia seedlings that treated by the high-temperature sunlight,methyl bromide fumigation and formalin disinfection was significantly reduced.But the mortality of the Begonia seedlings that without any treatment can account for 67%in 8 weeks after the transplantation,however,it was just 11%when it comes to the control,thus,the corrected ...
