| 摘 要： | 通过对孔雀草进行叶面施肥和遮光处理,研究了施肥和遮光对孔雀草的营养生长、鲜质量及开花的影响.结果表明:叶面施肥和遮光对孔雀草的生长发育存在一定的交互效应,其中,施肥条件下,孔雀草的遮光效应较不施肥时更明显,遮光能够导致施肥后孔雀草的分枝数显著减少,鲜质量显著下降,现蕾开花期延迟,花期缩短,花数减少,花径变小,而施肥对孔雀草的影响与其是否遮光关系不明显,不论遮光与否,喷施叶面肥都能够使孔雀草植株生长速度加快,分枝能力增强,物质积累增加,花数增加,花径增大.

| Abstract: | The effects of leaf fertilization and shading on the growth,fresh weight and anthesis of Tagetes patula were studied.The results indicated that leaf fertilization and shading had an interactional effects on Tagetes patula.The effects of shading on the growth and development of Tagetes patula was related closely to the fertilizer condition,while that fertilizer in Tagetes patula was not related to the shading rate.Compared with no fertilization,the Tagetes patula with leaf fertilization were affected by shading more significantly.With the increasing of shading level,the growth rate of Tagetespatulabecame slower,branch number and plant fresh weight were less than the control.Because of shading,the bloom time was delayed and anthesis was also shortened,and the number of flowers was decreased evidently.However,Tagetes patula with no fertilization was less affected by shading.Under the shading condition,the growth and development of Tagetes patula could be promoted by using leaf fertilization,which were mainly showed in the quicker growth rate,the stronger ability of ramification,the more fresh weight,the earlier bloom,the more flower number and the bigger flower diameter. |
