3种叶面肥对碧玉兰营养元素影响的探究

Study the Effect of Three Foliar Fertilizer on Nutriment of Cymbidium Lowianum

以碧玉兰为研究对象,通过采用随机区组试验设计,研究了3种叶面肥(磷酸二氢钾、生命素、翠筠B-2成长肥)在不同体积分数处理下,碧玉兰N,P,K质量分数的变化.结果表明:3种不同肥料对碧玉兰体内全N质量分数无显著影响,与施肥种类、施用体积分数无关;而全P、全K分别在施用生命素600倍、体积分数为3‰磷酸二氢钾时相对较高,即有利于其旺盛生长.

By taking Cymbidium Lowianum as the research object, randomized block experiment was used, the change of the nutrient fertilized with three different foliar fertilizer （ Potassium Dihydrogen Phosphate, Biogen, Cuijun B-2） were studied. The aim is to provide reference for the quality fractional change of N, P, K of Cymbidium Lowianum handled under different area fraction. The results showed that there was no significant effect on the content of total N to Cymbidium Huxueense fertilized with three fifferent fertilizer and has no correlation with fertilizer type or application concentration. Bnt the content of total P and total K were relatively high when the treatment concentration of Biogen is at dilutions of 1： 600. When the treatment concentration of Potassium Dihydrogen Phosphate is at dilutions of 3：1 O00,it was beneficial to exuberant growth.
