摘　　要：设置田间小区试验,以探讨喷施腐植酸水溶肥对冬莴笋产量、品质及效益的影响。结果表明:移栽后的15、25和35 d,用120 g/667m^2腐植酸水溶肥料对清水60 kg/667m^2进行叶面喷施,能使冬莴笋产量提高120 kg/667m^2以上,增产率在7%以上,可增加收入200元/667m2以上,降低了投入产出比,显著提高了冬莴笋食用茎可溶性糖和VC含量,显著降低了硝酸盐含量。冬莴苣喷施该肥料,技术简单实用,增产增效明显,建议在生产上推广应用。The effect of humic acid water-soluble fertilizer on the yield,quality and benefit of winter lettuce was studied by field plot experiment.The results showed that after 15,25 and 35 days of transplanting,1.8 kg/hm2 humic acid water-soluble fertilizer and 900 kg/hm2 clear water were used for foliar spraying,which could increase the yield of winter lettuce by more than 1800 kg/hm2,above 7%,increase the income by more than 3000 yuan/hm2,reduce the input-output ratio,significantly increase the soluble sugar and Vc contents of edible stems of winter lettuce,and significantly reduce the nitrate content.Spraying the fertilizer on winter lettuce is simple and practical with obvious increase in yield and efficiency.It is suggested that it should be popularized and applied in production.
