摘要(Abstract):

以旋覆花为研究对象,采用"3414"正交实验设计,研究氮磷钾配方施肥对旋覆花生长及化学成分含量的影响,初步揭示旋覆花的需肥特性,为旋覆花人工栽培提供施肥指导。结果表明,不同的氮磷钾配方施肥对旋覆花植株形态、生理生化指标、干物质积累量及化学成分含量均有显著性影响,随施肥量的增加,旋覆花的各项生长指标及化学成分含量均呈上升趋势,尤以氮肥最为显著;将各项指标进行隶属函数分析,综合评价后得出旋覆花最佳氮磷钾配方施肥水平为N3P2K2,即高水平氮肥,中水平磷肥和钾肥。旋覆花为喜肥植物,合理的施肥策略为"重施氮肥,适当补施磷钾肥"。
Inula japonica was used as the research object, "3414" fertilization experiment were conducted to study the effects of nitrogen,phosphorus and potassium formula fertilizer on the growth and chemical composition content of I. japonica. The characteristics of fertilizer requirement were preliminarily revealed and the study provided fertilization guidance for artificial cultivation of I. japonica. The results showed that different nitrogen,phosphorus and potassium formula fertilizers had significant effects on plant morphology,physiological and biochemical indexes,dry matter accumulation and chemical composition content. The growth indexes and chemical components of I. japonica showed an upward trend with the increase of fertilization amount,especially the nitrogen fertilizer was the most significant. The indicators were analyzed by membership function. After comprehensive evaluation,the optimal nitrogen,phosphorus and potassium formula fertilization level was N3 P2 K2,namely high level nitrogen fertilizer,medium level phosphorus fertilizer and potassium fertilizer. I. japonica is a high fertilizer demand plant,and the rational fertilization scheme is " applying nitrogen fertilizer again and applying phosphorus and potassium fertilizer properly".
