不同有机肥对小拱棚西瓜产量及土壤理化性质的影响

研究3种不同类型有机肥的肥效特点以及对小拱棚西瓜生长发育的影响。结果表明:施用有机肥处理的土壤盐分含量、速效氮低于对照,有机质、速效磷钾含量高于对照,西瓜长势和产量低于对照,但西瓜品质明显优于对照;菌肥处理的土壤肥力指标在西瓜结果初期表现最高,其它时间处于中等水平,鸡粪处理的土壤肥力在西瓜整个生育期变化幅度都很小,性质比较稳定,施用油饼肥处理的土壤理化指标在西瓜坐果期后含量均较低;3种有机肥使用效果表明,微生物菌肥处理的西瓜产量最高,品质最优,其次为商品鸡粪,再次为油饼肥。

Effect of Different Organic Fertilizers on the Watermelon Yeild and Soil Physical and Chemical Properties Under Row Cover

In this experiment,the characteristics and the effect on the growth of watermelon under three organic fertilizers were compared.The results indicated that the soil salt and available nitrogen content of organic fertilizers treatment were significantly lower than control,meanwhile the soil organic matter,available phosphorus and available potassium were higher than control.The watermelon growth vigor of treatment were weaker,but the quality were better.Among them,the soil fertility of bacterial manure treatment was highest during fruit setting stage and was at moderate level in other stage;the change range of soil fertility was litter at whole growth period in chicken manure treatment;the soil physicochemical index of cake fertilizer was all lower after fruit setting stage.Comparison of application effects,the yield of bacterial manure treatment was highest and the quality was best,followed by chicken matter and cake fertilizer.
