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。
Taking the garden soil as matrix, the pot experiment was carried out with 8 treatments of # FSN, P, K and their different combinations. The results showed that potash fertilizer was the key fertilizer for high quality and high yield of broccoli. When combined with N or NP, potash fertilizer had additive effect on the ratio of source and sink, yield, VC content and chlorophyll content. NK treatment could be increased by 110 .8%; N fertilizer can be harvested early; broccoli production and aboveground dry weight, plant development degree was a significant positive correlation. Comprehensive analysis of yield, quality traits, broccoli need NPK with the application in order to promote the accumulation of photosynthetic products, increase yield, and improve the quality of flower ball.
