    轻型基质栽培条件下氮浓度对独本菊紫如意'生长开花的影响

    Effects of nitrogen concentration on growth and flowering of standard chrysanthemum Ziruyi' under light-substrate cultivation

    • 摘要: 为精准把握独本菊轻型基质栽培氮施肥水平,以品种紫如意'为研究对象,以V草炭:V珍珠岩:V蛭石=1:1:1为栽 培基质,氮营养处理质量浓度为100、150、180、210、240 mg/L 5 水平进行了栽培试验。结果表明:5 个处理条件下, 紫如意'生长开花均属正常,未有显著养分缺乏或过剩现象出现。当氮元素质量浓度从100 mg/L 增加到210 mg/L 时,株高、展叶数、花径、茎粗、叶面积呈升高趋势,当氮元素质量浓度高达240 mg/L 时,各项指标又有所下降。综合 考虑认为,氮元素质量浓度为210 mg/L 时紫如意'生长开花指标最佳,花型丰满,脚叶饱满,茎梗挺直,故认为该 质量浓度为本试验条件下最理想氮肥浓度。

       

      Abstract: In order to study exact nitrogen concentration of light-substrate standard chrysanthemum Ziruyi', using Vpeat:Vvermiculite:Vperlite =1:1:1 as substrate, nitrogen concentration of 100, 150, 180, 210, 240 mg/ L was used for cultivation study. The results showed that in all levels of nitrogen concentration, growth and flowering of Ziruyi'were on normal level, plants never performed deficiency or excessive. With nitrogen concentration changed from 100 to 210 mg/L, plant height, leaf number, flower diameter, stem diameter and leaf acreage performed rising trend. Most indicators decreased in nitrogen concentration of 240 mg/L. Comprehensively, chrysanthemum Ziruyi'reached the best appreciation standard in nitrogen concentration of 210 mg/L, so we regard this concentration as optimal nitrogen concentration in this study.
