摘要
通过２ａ（年）对洋葱施用不同量钾肥的试验表明，施用钾肥能显著提高洋葱产量和经济效益；洋葱ＶＣ含量随钾肥用量增加而提高，施钾还能提高糖分含量，但施钾量大时则呈下降趋势，糖分最高含量出现在产量最高值之前；钾肥促进了氮肥的吸收和氮素代谢。
The experimental results indicated that the application of K fertilizer increased the onion yield and economic efficiency of production. The VC content of onion increased with the K rate. Although the K could increased the sugar content of onion,it decreased while large rate of K fertilizer applied. The K application promoted the uptake and metabolism by onion.
