不同肥料配比对大花蕙兰“YX52”生长的影响

在同种基质条件下,研究不同肥料配比500mg/kgK2SO4复合肥(处理1)、500mg/kgKH2PO4+1000mg/kgCO(NH2)(2处理2)、500mg/kgK2SO4复合肥+缓释肥(处理3)、500mg/kgKH2PO4+1000mg/kgCO(NH2)2+缓释肥(处理4)对大花蕙兰品种"YX52"(星月)生长的影响。结果表明:处理4对植株营养生长及提高叶绿素含量效果最为显著,处理4与处理3能缓解高温对大花蕙兰植株生长的不利影响。这说明在使用缓释肥基础上,喷施500mg/kgKH2PO4+1000mg/kgCO(NH2)2有利于大花蕙兰的生长,可作为在大花蕙兰生产经营中施肥的辅助措施;500mg/kgK2SO4复合肥与500mg/kgKH2PO4+1000mg/kgCO(NH2)2由于营养元素单调,不能满足大花蕙兰生长所需的养分;而500mg/kgK2SO4复合肥+缓释肥不能用于生产。

Effect of Fertilizer Treatments on the Growth of Cymbidium hybridum "YX52"

Effects of different proportion of fertilizers on the growth of Cymbidium hybridum variety "YX52" (star moon) were studied under the same substance. The results showed that the treatment 4(500 ppmKH2PO4 1 000 ppm CO(NH2)2 controlled release fertilizer)increased the rate of vegetative growth and proved chlorophyll content most obviously. Treatment 4(500 ppm KH2PO4 1000 ppm CO(NH2)2 controlled release fertilizer) and treatment 3 (500 ppm K2SO4 compound fertilizer controlled release fertilizer)partially prevented from elevated temperatures. On the basis of using controlled release fertilizer, spraying 500 ppm KH2PO4 1 000 ppm CO(NH2)2 helped the growth of Cymbidium hybridum, which could be used as a auxiliary measure in its production. Treatment 1(500 ppm K2SO4 compound fertilizer) and treatment 2 (500 ppm KH2PO4 1 000 ppm CO(NH2)2) with a little nutrition did not content adequate nutrition for Cymbidium hybridum growth. And treatment 3(500 ppm K2SO4 compound fertilizer controlled release fertilizer)could not be used in production.
