| 摘 要： | 目的]研究不同配方施肥对辣木生长效应及产量构件因素的影响,方法]采用正交设计L9(34)3因素3水平进行施肥试验。结果]施肥处理对各时期生长有显著的促进作用,且营养生长期N肥和K肥占主导作用。适合株高和地径生长的最优组合为N150P40K100,而适合冠幅和分枝数生长的最优组合为N85P85K100。生殖生长各指标较对照均有明显提高。低浓度的氮肥和高浓度的磷钾肥有助于辣木的开花和座果,同时提高果荚产量和种子产量,明显促进产量增加以及花序数、成熟果数、百粒质量和座果率的提高。结论]合理的配比施肥显著促进辣木的生长效应以及提高产量,果荚产量和种子产量的最优组合为N_(40)P_(150)K_(100)。

| Abstract: | Objective] To study the effect of different formula fertilization on the growth and yield component of Moringa oleifera. Methods] Orthogonal design L9 (34) with 3 factors 3 levels fertilization experiment was carried out. Results] The results showed that fertilization treatment significantly promoted the growth in each period, and N fertilizer and K fertilizer dominated role in the vegetative growth. The optimal combination suitable for the growth of plant height and ground diameter was N150P40K100, while that for the crown and the number of branch growth was N85P85K100. The reproductive growth increased obviously compared to control. Low concentration of nitrogen and high concentration of phosphate and potash fertilizer contributed to M. oleifera flowering and fruit setting, and improved the pod and seed yields, and significantly increased the ordinal numbers, the numbers of mature fruit, hundred kernel weight and fruit-set rate. Conclusion] Reasonable proportion of formula fertilization could significantly promote growth and increase production of M. oleifera. The optimal combination is N40P150K100 regarding the pod and seed yields. |
