本文通过温室田间实验,研究了东方百合的养分吸收规律和分配特点。结果表明,现蕾以前,以消耗鳞茎中的养分为主,供应百合植株生长;由现蕾开始,历时30天,为百合吸收氮素的高峰期,现蕾始历时45天为百合吸收磷的高峰期,钾的吸收较早,由展叶期开始,直至切花期,共计75天。氮、磷、钾在各器官的分布:现蕾以前以叶片为主,茎秆次之,地下部最少;随着百合的生长,地下部养分比重上升,进入切花期后,茎、叶养分降低,以地下部和花蕾为主。百合吸收氮、磷、钾的比值:现蕾以前为1∶0.17∶1.08,现蕾以后为1∶0.15∶1.45。
In this paper, field experiments in greenhouse were conducted to study the law of nutrient absorption and distribution of oriental lily. The results showed that before budding, the main nutrients in the bulbs were spent on the supply of lily plant growth; from budding, which took 30 days to absorb the peak of nitrogen for lily, Peak, potassium absorption earlier, beginning from the leaf stage, until the flowering stage, a total of 75 days. The distribution of nitrogen, phosphorus and potassium in various organs: Before budding, the leaves were dominant, followed by the stems, and the lowest ones. With the growth of lily, the proportion of nutrients in underground soil increased, and after the flowering stage, the nutrients in stems and leaves decreased , Mainly to the ground and buds. Lily absorb nitrogen, phosphorus and potassium ratio: Budding was 1: 0.17: 1.08, after budding 1: 0.15: 1.45.
