Effect of Different Nitrogen Amount on Growth and Fruit Setting of Potted Ilex verticillata ‘Oosterwijk’

摘要: 2014年选用2年生盆栽‘奥斯特’北美冬青(Ilex verticillata ‘Oosterwijk’),施用0、50、100、150、300 mg/kg五种不同浓度氮肥,分析其对盆栽苗生长及座果的影响。结果表明:在N0 ~ N150,随着施氮量的增加,座果枝长、叶长和叶宽、营养枝叶长和叶宽、座果枝叶数、果径、主杆粗、一级分枝数、单位长度座果数都随之增大,而营养枝长、营养枝叶数反而减小;当达到N300水平时,单位长度座果数、座果枝长、座果叶数反而较N150减少。综合考虑其生长和观赏价值,建议最适的施氮量为150 mg/kg。Abstract: Experiments were conducted on applying 0, 50, 100, 150 and 300mg/kg of N fertilizer in 2-year potted Ilex verticillata ‘Oosterwijk’ in 2014. Determination demonstrated that branch length, leaf length and width of bearing branch,leaf length and width of nutritive branch, leaf number of bearing branch, fruit diameter, diameter of stem, branching number and unit length fruit number increased with N amount from 0 to 150 mg/kg, while nutritive branch length and leaf number decreased. But under N300, unit length fruit number, length of bearing branch, leaf number of bearing branch were lower than under N150. The experiment resulted that the optimal fertilizer amount was 150mg/kg.
