摘要: 以园田土为基质,采用#FSN、P、K肥及其不同组合共8个处理进行盆栽试验。结果表明,钾肥是青花菜优质高产的关键肥料,其与N或NP组合施用,对源库比例、产量、VC含量及叶绿素含量等具有加成作用,NK处理可比单独用N单球重提高110.8%;N肥可提早采收期;青花菜产量与地上部干重、植株开展度等呈极显著正相关。综合各产量、品质性状等分析,青花菜需NPK配合施用,以促进光合产物的积累,提高产量,并改善花球品质。

Abstract: Effects of different combinations of N,P,K fertilizers on growth and yield of ginger were tested. The result indicated that the middle-level treatments,N 40kg,P 2O 5_7.5kg,K 2O 40kg per 667m 2,was the best,giving higher shoots,more and stronger branches,larger leaf area,more accumulation of dry matters and higher yield.
