| 摘 要： | 以丰水和翠冠两个南方优质早熟梨品种为研究材料,分析了气候条件、梨品种特性、水肥管理模式以及生理异常发生前后6个月内植株叶片氮、磷、钾等主要营养元素含量变化与桂北地区梨树生理异常现象形成的关系.结果表明:丰水梨更容易发生生理异常现象；桂北地区秋冬季气温偏高、夏秋之交高温干旱、品种遗传特性、病虫危害和梨园的综合管理措施不到...

| Abstract: | Two cultivars of South-Early-Ripening-Pear,Pyrus spp.cv.Fengshui and Pyrus spp.cv.Cuiguan,were used as experimental trees to investigate on their cultural environments,cultivar,water and fertilizer managements,as well as the variation of contents of some main nutrition elements(N,P,K) in the leaves within 6 months before and after physiologic abnormity occurrence,and then the relationships of these factors were analyzed with the forming of physiologic abnormity in North Guangxi.The results showed that physi... |
