| 摘 要： | 通过盆栽试验 ,研究了B、K、Mn、Mg、Zn、Co对青菜中硝酸盐含量的影响。结果表明 :增施硼酸钠后第 2 0天 ,青菜硝酸盐含量比对照降低 1 4 84%～ 1 9 56 % ;增施K、Mn、Mg、Zn、Co也能降低青菜硝酸盐含量。每盆增施0 1gZnSO4 后第 1 0天 ,青菜中硝酸盐含量比对照减少 1 8 96 % ,每盆增施 0 1gK2 SO4 后第 2 0天 ,青菜中硝酸盐含量比对照减少 2 1 42 % ;矿质元素的施用量对青菜硝酸盐含量影响较大。

| Abstract: | Effects of sodium borate,potassium sulfate,manganese sulfate,magnesium sulfate,zinc sulfate and cobalt sulfate on nitrate contents in vegetable have been studied by pot experiment with Brassica chinensis .The results showed that nitrate contents in Brassica chinensis decreased by 14.84%-19.56% after application of sodium borate for 20 days,and also decreased significantly by using K?Mn?Mg?Zn and Co.Nitrate content decreased by 18.96% 10 days after application of zinc sulfate and by 21.42% 20 days after application of potassium sulfate.Application rate of the mineral elements showed significant effects on the accumulation of nitrate in Brassica chinensis . |
