摘要
研究了有机水溶性肥与无机肥配施对包菜产量、养分吸收和经济效益的影响。结果表明:与单施无机肥相比,有机水溶性肥以灌根的方式与无机肥配施能显著提高包菜的包心率、包心重、产量、经济效益以及叶片中叶绿素、磷、钾的含量,并在一定程度上提高包菜氮、磷、钾的累积量和各养分利用效率;有机水溶性肥与无机肥灌根的综合效果优于叶面喷施的综合效果。
The influences of combined application of water -soluble organic fertilizer and inorganic fertilizer on the yield , nu-trient absorption and economic benefit of cabbage were studied .The results revealed that：as compared with the single application of inorganic fertilizer , the application of water -soluble organic fertilizer in the manner of root -irrigation combined with inorganic fer-tilizer could significantly enhance the package rate , package weight , yield and economic benefit of cabbage , as well as the contents of chlorophyll , phosphorus and potassium in cabbage leaf , and could increase the accumulation and utilization efficiency of nitrogen , phosphorus and potassium in cabbage to a certain degree .The combined application of water -soluble organic fertilizer and inorganic fertilizer in the manner of root -irrigation obtained better comprehensive effect than that in the manner of foliage spray .
