3种腐植酸水溶肥料在小青菜上的应用效果初探

Preliminary Study on Application Effects of Three Humic Acid Water-soluble Fertilizers on Pakchoi

为研究宿州市“天河百润”“黑包公”“森正达”3种腐植酸水溶肥料对小青菜产量与经济效益的影响,于2020年8月至2022年8月,分别在宿州市埇桥区不同地点进行了小青菜应用3种不同腐植酸水溶肥料效果试验,试验设基施底肥+叶面喷施腐植酸水溶肥料、基施底肥+叶面喷施清水以及基施底肥(CK)3个处理。结果表明:在基施底肥的基础上,3种腐植酸水溶肥料对小青菜生长发育均有不同程度的促进作用,能有效改善小青菜的产量构成因素,有助于小青菜产量的形成,对增加小青菜产量和经济效益效果显著,增产幅度7.11%~9.32%。

To study the effects of three humic acid water-soluble fertilizer products of"Tianhebairun","Heibaogong"and"Senzhengda"on the yield and economic benefits of pakchoi.From August 2020 to August 2022,the experiments on the effects of three different humic acid water-soluble fertilisers were carried out at different locations in Yongqiao District,Suzhou City,with three treatments:base fertilization+foliar spraying of humic acid water-soluble fertilizer,base fertilization+foliar spraying of water and base fertilization(CK).The results showed that,on the basis of base fertilization,three humic acid water-soluble fertilizers could promote the growth and development of pakchoi in different degrees,effectively improve the yield components of pakchoi,be helpful to the formation of the yield of pakchoi,and had a remarkable effect on the increase of the yield and economic benefit,the increase range was 7.11%~9.32%.
