腐植酸液体肥料与化肥配施对设施栽培西瓜的影响

Effects of Application of Humic Acid Liquid Fertilizer Combined with Chemical Fertilizer on Facility Watermelon

为探究腐植酸液体肥料与化肥配施对西瓜的肥效,以常规施肥作对照,研究了腐植酸液体肥料与化肥配施对西瓜生长性能、产量和甜度的影响。结果表明,腐植酸液体肥料与化肥配施可促进西瓜的生长发育,保证西瓜增产、稳产,改善西瓜甜度品质。腐植酸液体肥料与常规施肥配施效果最好,增产率为24.94%;在化肥减量30%、50%的条件下,腐植酸液体肥料与化肥配施增产、稳产效果明显,增产率分别为13.96%、3.49%,节肥效果明显。

In order to study the effect of application of humic acid liquid fertilizer combined with chemical fertilizer on watermelon, the growth performance, yield and sweetness of watermelon were studied with a control of conventional fertilization. The results showed that application of humic acid liquid fertilizer combined with chemical fertilizer could promote the growth and development, ensure the increase and steady yield, and improve the sweet quality of watermelon. The effect of humic acid liquid fertilizer combined with conventional fertilizer was the best, the yield increasing rate was 24.94%. Under the condition of 30% and 50% reduction of fertilizer, the effect of liquid humic acid fertilizer combined with chemical fertilizer on increasing and stabilizing yield was respectivly, the increasing rate was 13.96% and 3.49%, and the effect of saving fertilizer was obvious.
