摘要
[目的]通过对澳洲坚果冻害及恢复的调查,了解霜冻气候对澳洲坚果生长造成的影响,为澳洲坚果产业发展提供理论依据.[方法]把冻害程度分为6级,并对4级危害进行跟踪观察.[结果]澳洲坚果苗受害率99.5％,死亡率1.9％;在4级危害中,地径伤口以上部分枝叶生长缓慢,伤口以下抽生活跃;在冻伤后未死亡的植株中,伤口愈合需1～2年.[结论]0～3级冻害对澳洲坚果生长影响不大,4级以上冻害建议换苗.
Abstract
[Objective] The effects on the growth of Macadamia ternifolia F.Muell.under the condition of frost climate were studied in order to provide theoretical basis for the macadamia industry development through the investigation and analysis of macadamia nut on cold injury and recovery.[Method] The cold injury was divided into degree of level 6,and was tracked to grade 4 harm.[Result] Macadamia ternifolia seedlings suffered rate was 99.5％,and mortality rate was 1.9％.The leaf grew slowly above ground diameter cut parts and grow actively below the wound in grade 4 harm.Wound healing needed 1-2 years in the plant didn't die after frostbite.[Conclusion] The macadamia development did not much affect among level 0 to 3 freezing injury,and was suggested transplanting seedling above 4 class of freezing injury.
