采用田间小区试验,研究当前蔬菜的主要施肥模式(有机肥无机肥配施)下配合喷施锌、硼、铜、钼、锰及农用稀土对小白菜的产量、品质的影响。结果表明,配合喷施微肥或稀土对小白菜的产量影响无明显规律,但均能不同程度降低小白菜的硝酸盐和亚硝酸盐含量,与对照相比,春季、秋季小白菜的硝酸盐含量分别降低了3.1%～28.2%、6.4%～43.0%,亚硝酸盐含量分别降低3.0%～54.5%、0.0%～20.0%;春季小白菜的维生素C和秋季小白菜的可溶性糖含量分别提高18.6%～82.4%和3.6%～67.9%;耕层土壤中硝态氮含量降低8.5%～ The experiment of field plot was used to study the effects of spraying main fertilizing modes (organic manure and inorganic fertilizers) with zinc, boron, copper, molybdenum, manganese and agricultural rare earth on the yield and quality of Chinese cabbage at present. The results showed that no obvious regularity was found on the yield of Brassica chinensis cooperated with spraying fertilizers or rare earths, but the content of nitrate and nitrite in cabbage was reduced to some extent. Compared with the control, The content of nitrite reduced by 3.1% -28.2%, 6.4% -43.0% and nitrite decreased by 3.0% -54.5% and 0.0% -20.0% respectively; the content of soluble sugar of spring cabbage vitamin C and autumn cabbage increased respectively 18.6% -82.4% and 3.6% -67.9%, while nitrate nitrogen in topsoil decreased by 8.5%
