不同肥料配方对香石竹生长发育的影响

目的]筛选适合香石竹生长的最佳肥料配方。方法]供试香石竹品种为马斯特(R3),栽培基质为陶粒∶草炭=1∶1,共设3个不同肥料配方处理和1个不施肥处理(对照),每处理重复3次,研究不同肥料配方对香石竹的株高、茎粗、叶片长度、花蕾直径、根冠比、干物重的影响。结果]大量元素水溶性肥料处理的香石竹的株高、茎粗、花蕾直径、干物重分别为82.37 cm、0.79 cm、2.41 cm和0.56 g,均优于其他处理,也可有效促进香石竹的叶片长度和根部发育。结论]大量元素水溶性肥料是促进香石竹生长的最佳肥料配方。

Effects of Different Fertilizer Formula on Growth and Development of Dianthus caryophyllus L.

Objective] The aim was to screen out optimal fertilizer formula for Dianthus caryophyllus growth.Method] With Master(R3) as test variety, cultivation matrix ceramsite∶peat =1∶1, a total of four processing, namely three different fertilizer formula and one no fertilizer treatment(CK), each processing repeat 3 times, effects of different fertilizer formula on plant height, stem diameter, leaf length, bud diame-ter, root-shoot ratio, dry matter weight were studied.Result] Plant height, stem diameter, bud diameter, dry matter weight were 82.37, 0.79, 2.41 cm and 0.56 g of treatment of macroelement water soluble fertilizer, which are better than that of other treatments and can promote leaf length and roots development. Conclusion] Macroelement water soluble fertilizer is the optimal fertilizer formula to promote Dianthus caryophyllus growth.
