摘　　要：试验结果表明,在氮、磷、钾肥的基础上,增施钙镁肥系列产品,菜心增产3.7%-10.5%,平均增产7.2%。钙镁肥与碳铵随混随用,对氮肥肥效的影响不大;钙镁肥与磷肥混配生产的钙镁-磷肥、钙镁-磷钾肥,可能存在P、Ca元素的固定作用,使施用效果受到影响;钙镁肥与钾肥混配生产的钙镁-钾肥,则无不利影响。在钙镁肥系列中,腐植酸钙镁肥的增产最大,肥效最好,是值得大力推广的一个品种。增施钙镁系列肥料可增强植株对NPK养分吸收,提高肥料利用率,并且菜心商品性状好,增收效益较高。The yield of Chinese flowering cabbage increased 3.7%-10.5% and 7.2% averagely when serial products of Ca-Mg fertilizer were applied with suitable amount of nitrogen, phosphorus and potassium fertilizer. There was almost no effect on the efficiency of ammonium carbonate when Ca-Mg fertilizer was applied with ammonium carbonate. The effect of P fertilizer mixed with Ca-Mg fertilizer was weakened, maybe which was resulted from P and Ca were fixed. The effect of Ca-Mg fertilizer mixed with humic acid was the highest, and showed the greatest potential for increasing yield, so it was a kind of fertilizer to be recommended. Not only both the absorption of N, P, K and the recovery rate of fertilizer were improved, but also the commodity character of Chinese flowering cabbage was more better, and it obtained better benefit when series of Ca-Mg fertilizer were applied.
