摘要: 为探明江苏沿江高沙土地区花椰菜高产优质栽培的适宜施钾量,研究了不同施钾量对花椰菜产量和品质的调控效应。结果表明:不同的施钾量处理间花椰菜产量和品质存在显著差异,施钾能显著提高花椰菜的产量和品质,但施钾量达到一定值后,继续增施钾肥,则有害物质硝酸盐和亚硝酸盐含量显著增加,且Vc、锌、铁、钙等营养物质含量下降,产量下降,不利于花椰菜产量的提升和品质的改善。本试验条件下,花椰菜钾肥的适宜施用量为420 kg·hm-2。

Abstract: Experiments with different potassium application amounts were carried out on cauliflower to investigate the optimal potassium application amount for cauliflower with high yield and quality in local sandy soil area. The results showed that there was significant difference in yield and quality of cauliflower in different potassium application treatments. The yield and quality of cauliflower significantly increased when applied with potassium; however, the contents of nitrate and nitrite markedly increased and the nutrition elements such as Vc, Zn, Fe and Ca decreased, which caused the yield reduction and poor quality. In the local sandy soil area, the suitable potassium application amount of cauliflower was about 420 kg·hm-2.
