硫酸钾镁肥在百合上的应用效果及其施用方法研究

等钾条件下,在百合花上施用硫酸钾镁肥等3种不同类型钾肥,研究硫酸钾镁肥对百合生长的影响及其施用方法。结果表明,施用不同类型钾肥都能不同程度地促进百合生长及提高经济效益,特别是施用硫酸钾镁肥使百合株高增加6.5%、茎粗增加3.1%,并且能提高百合产花朵数、花朵大小及经济效益;硫酸钾镁肥采用基肥撒施、追肥喷施对百合生长的效果好于采用全部撒施。

Study on Applied Method and Result of Sulfuric Acid Potassium Magnsium in Lily Bulb

Applied method and result of three different types of fertilizer with equivalent potassium in lily bulb was researched magnesium potassium sulfate fertilizer. The results showed that the application of different fertilizers promoted Lily growth,and improved economic output. Fertilizer,especially sulfuric acid potassium magnesium,heightened plant 6.5%, thickened stalk 3.1% than the contrast, and also increased flower size and amount. It also showed broadcasting was better than mixed method of basal fertilizer broadcasting and top-dressing spraying of magnesium potassium sulfate fertilizer.
