摘要
2011年4月对贵州贞丰县的白层镇、鲁容乡和册亨县的巧马镇、者楼镇、八渡镇等地的麻疯树冻害情况进行调查,以便了解分析2011年初贵州麻疯树受冻害程度及受冻原因,为贵州麻疯树冻害预防提供指导。结果表明,两县5个乡、镇的8个村组麻疯树都受到不同程度冻害,其中以贞丰县鲁容乡孔索村和册亨县者楼镇平秧村的麻疯树死亡率最高,分别为81.7%和93.84%,综合分析,树龄较长的当地品种受害较轻,抗冻能力比引进品种强。
The study was conducted to investigate the degrees of freezing injuries of Jatropha curcas in Zhenfeng and Ceheng during Apr.2011. To konw reason of freezing injuries is our intention.The results show that the Jatropha curcas in five rural counties, towns, eight villages were subject to different frost damage.Which allow Conso Zhenfeng Lu Village and ceheng by building the village level seedling mortality is highest, 81.7%, respectively, 93.84%.
