| 摘 要： | 目的]研究油莱根、茎枝、叶片等营养器官后期磷素的再利用与角果中磷素积累的关系。方法]以甘蓝型油莱品种“扬油4号”为试验材料，通过测定不同生育期不同施磷条件下油菜各器官的磷素含量，研究了油莱后期根、茎枝、叶片等营养器官中磷素的输出和角果中磷素的积累。结果]根、茎枝、叶片中磷素积累量的变化呈先增后减的趋势？角果是油菜植株主要的磷素贮藏器官，增施磷肥可增加各器官的磷素积累量。增施磷肥使得茎枝和叶片中的磷素输出量增加。根茎叶的磷素输出比例相差不大，在40％～45％、结论]成熟期角果中的磷素总量至少有40％左右来自初花前根茎叶积累磷素的再利用.

| Abstract: | Objective] The aim was to study the relationship of remobilization of phosphorus in root,stem and leaf and the accumulation of phosphorus in pods in rapeseed.Method] The content of phosphorus was tested in Yangyou NO.4(Brassica napus L.) in different phosphorus levels and phosphorus translocation in root,stem and leaf and the phosphorus accumulation in pods were studied.Result] The total amount of phosphorus in root,stem and leaf increased firstly and then decreased in whole stages.With the increasing of... |
