叶面喷施微肥对橡胶苗叶片营养含量的影响
Effects of Trace Element Fertilizer on Nutrient Content of Rubber Tree Buddings by Foliar Application
摘要
Abstract
Taking SCATC 7-33-97 as the experiment material,the effects of different levels of water-soluble trace element fertilizer (Trace element fertilizer) on the contents of N,P,K,Ca and Mg in rubber budding leaves were studied.The results showed that the content of N in the first and second canopy leaves reached extremely significant effect at different concentrations of trace fertilizer,and both reached its maximum at a trace element fertilizer concentration of 2.5 mg/kg.The P content of the first to third canopy leaves reached significant effect at different concentrations of trace fertilizer,and reached its maximum at a concentration of 2.5～3.5 mg/kg.The K content of the second and third canopy leaves reached significant effect,and reached its maximum at trace element fertilizer concentration of 2.5 mg/kg.In conclusion,foliar application of trace element fertilizer on rubber budding leaves could significantly promote the absorption of N,P,K,Ca and Mg,and the optimal foliar applied concentration of microelements was 2.5 mg/kg.关键词
