【摘要】 通过设计N、P、K大量元素叶面肥的不同浓度配方,对成林油茶进行正交施肥试验,根据施肥对油茶叶片叶绿素含量的影响来筛选叶面肥配方。结果表明:有利于提高叶绿素含量的大量元素叶面肥最佳配方为A₂B₂C₃D₂,即N∶P₂O₅∶K₂O为4∶2∶2.8,喷施浓度为1%（以尿素计）。具体折算成肥料为:尿素1%,磷酸氢二钾0.44%,氯化钾0.27%。更多还原

【Abstract】 Through the orthogonal experiment of the fertilizer application of N,P and K,the effect of fertilization on the chlorophyll content of Camellia oleifera leaf was selected. Based on the analysis of variance,the formula for increasing the amount of element foliar fertilizer with better chlorophyll content was selected and the optimum formula was A₂B₂C₃D₂,which is N∶P₂O₅∶K₂O=4∶2∶2.8,the solubility of 1%（urea spraying meter）. Specific conversion into fertilizer: urea of 1%,potassium hydrogen phosphate of 0.44%,potassium chloride of 0.27%.更多还原
