摘要
通过田间试验和室内分析对南板蓝不同时期各器官及整株养分的质量分数进行了研究.结果表明,不同时期南板蓝植株及各器官养分的质量分数都表现为N>K>P;南板蓝不同器官氮、磷、钾三养分的质量分数表现为叶>茎>根;不同时期南板蓝氮、磷、钾素的质量分数都表现出明显差异,其中氮素的质量分数以7～8月最高,磷素的质量分数以6～7月最高,钾素的质量分数在8月较高.初步将南板蓝的营养生长期划分为种植-成活期、幼苗期、生长旺盛期及收获期4个主要时期.
Using the field experiment and chemical analysis,this essay studied the nutrition characteristics of different periods and different growing periods for Baphicanthus Cusia Bremek.The results showed that nutrition content of N,K,P in its whole body and every organ are on the decrease sequentially. The organs of leaves, stems and roots containing the nutrition content are on the decrease sequentially. Different periods have different nutrition content. The content of N is highest in 7～8 months,P in June and July months, K in August.Baphicanthus Cusia Bremek have four major nutrition periods:planting and sprouting perios young shoot periods, vigorous growth periods and harvest periods.
