摘　　要：为探寻合理的化肥与有机肥配施方式,改善青花菜生长、品质、土壤状况及经济效益,以国王100青花菜品种为材料,采用单因素随机区组设计,以不施用肥料的CK和常规施用化肥的CF为对照,设置T200(化肥减施25%+增施200 kg·667 m^(-2);有机肥)和T400(化肥减施25%+增施400 kg·667 m^(-2);有机肥)2个处理。结果表明,T200、T400处理分别较CF每667 m^(-2);增产126.23、61.71 kg^(-1)T200处理下可溶性糖含量最高,为7.48 m^(-2)g·g^(-1);青花菜对钾肥的吸收利用率在T200处理下达到最高,且显著高于其他处理。综上所述,在T200(化肥减施25%+增施200 kg·667 m^(-2);有机肥处理)可以提高青花菜品质、增强肥料有效性、改善土壤养分环境、增加农民收益,是一种适于生产需要、提升青花菜种植经济效益的合理施肥方式。Broccoli variety Wang 100 was grown with reduce chemical fertilizer and increased organic fertilizer to explore the benefits of combined use of chemical and organic fertilizers in improving growth,quality and soil condition.Two treatments T200(25%reduction in chemical fertilizer+increased application of 200 kg·667 m;organic fertilizer)and T400(reduced application of chemical fertilizer by 25%+increased application of 400 kg·667 m;organic fertilizer)were tested using without fertilizer(CK)and normal chemical fertilizer(CF)as controls.The results showed that,compared with CF,T200 and T400 treatments increased yield by 126.23 kg·667 hm^(2) and 61.71 kg·667 hm^(2).The highest content of soluble sugar was observed with T200 treatment(increased by 7.36μg·g;).The absorption and utilization of potassium were the highest with T200 treatment.T200 treatment can improve the quality of broccoli,enhance the availability of fertilizer,improve the soil condition,and increase the income of farmers..
