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。
关键词: 洋葱, 钾肥, 产量, 品质, 养分吸收
Abstract: 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.
