高山大白菜和白萝卜施用锰硅肥料的效果

Effect of Manganese-silicon Fertilizer on Chinese Cabbage and White Radish in An Alpine Belt

对高山大白菜和白萝卜施用锰硅肥料的效果进行了试验研究。结果表明,大白菜每公顷施用锰硅肥375 kg和30%氮、磷、钾复合肥2 250 kg,增产效果最好;白萝卜每公顷施用锰硅肥1 500 kg和30%氮、磷、钾复合肥1 500 kg,增产效果最好。两种蔬菜施用锰硅肥对提高品质、减少病害有一定的作用。利用废锰硅矿渣开发新型肥料在大白菜、白萝卜生产上应用,有广阔的增产增收前景。

The effect of manganese-silicon fertilizer on Chinese cabbage and white radish in highland was studied. The yield of Chinese cabbage was highest with applying 375 kg.hm^-2 manganese-silicon fertilizer and 2 250 kg.hm^-2 N-P-K compound fertilizer（30% content）. The yield of white radish was highest with applying 1 500 kg.hm^-2 manganese-silicon fertilizer and 1 500 kg.hm^-2 N-P-K compound fertilizer （30% content）. Manganese-silicon fertilizer may play a role in improving quality and decreasing diseases in Chinese cabbage and white radish. Therefore, manganese-silicon fertilizer presents broad prospect for practical application.
