含腐植酸水溶肥料是在农业生产中广泛使用的新型肥料。为了探索含腐植酸水溶肥料在黄瓜上喷施的适宜浓度,在北京市通州区进行黄瓜生长期喷施不同浓度含腐植酸水溶肥料试验,通过对黄瓜产量、效益等因素分析,在该土壤条件下,黄瓜喷施400～2000倍液含腐植酸水溶肥料后,黄瓜增产明显,增产率2.0%～8.9%。喷施1200倍液含腐植酸水溶肥料与喷施400倍液处理达到极显著水平,其中叶面喷施1200倍液处理产量最高,黄瓜平均产量5741.20kg/667m2,比喷清水处理增产471.10kg/667m2,增产率达8.9%。
Humic acid containing water-soluble fertilizer is widely used in agricultural production of new fertilizers. In order to explore the appropriate concentration of humic acid soluble fertilizer sprayed on cucumber in Tongzhou District of Beijing cucumber growth during spraying different concentrations of humic acid containing water-soluble fertilizer test cucumber yield, benefit and other factors, the soil conditions Under the cucumber spraying 400 ~ 2000 times with humic acid water-soluble fertilizer, the cucumber yield significantly, yield 2.0% ~ 8.9%. Spraying 1200 times with humic acid water-soluble fertilizer and spraying 400 times the treatment reached a significant level, of which foliar spray 1200 times the highest yield of treatment, the average yield of cucumber 5741.20kg / 667m2 than spray water treatment yield 471.10kg / 667m2, increase rate of 8.9%.
