茎瘤芥品种硝酸盐含量分析初报

A Report on the Analysis of Nitrate Content in Different Tissues of Tumorous Stem Mustard

随机采集收获期茎瘤芥品种,仪器测定硝酸盐含量。结果表明:涪杂2号、泡叶、半碎叶的硝酸盐含量相对较高,永安小叶、小花叶、柿饼菜品种的硝酸盐含量中等,蔺市草腰子的硝酸盐含量最低。涪杂2号在栽培上更应控制最后一次追肥的时间和用量,亦或稍作延迟采收。

The tumor stem mustard were randomly collected at harvest stage and the nitrate content was determined by instrument. The results showed that the nitrate content of No.2 Fuze, bubble leaf and semibroken leaf are relatively high, Yong-an small leaf, small mosaic leaf and persimmon variety were middle,and the nitrate content of Linshi grass was the lowest. No.2 Fuze should control the time and amount of the last topdressing in cultivation, or slightly delay the harvest.
