微量元素水溶肥料是在农业生产中广泛使用的新型肥料。为了探索微量元素水溶肥料在番茄上喷施的适宜浓度,在北京市通州区进行番茄生长期喷施不同浓度微量元素水溶肥料试验,通过对番茄产量、效益等因素分析,在该土壤条件下番茄喷施400～2000倍液微量元素水溶肥料后,番茄增产明显,增产率2.0%～10.0%。喷施1200倍液微量元素水溶肥料与喷施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,番茄平均产量7079.10kg/667m2,比喷清水处理增产648.60kg/667m2,增产率达10.1%。
Trace elements water-soluble fertilizer is a new type of fertilizer widely used in agricultural production. In order to explore the appropriate concentration of micronutrient water-soluble fertilizer sprayed on tomato, the experiment of spraying different concentrations of trace element water-soluble fertilizer on tomato growth stage was conducted in Tongzhou District, Beijing. Based on the analysis of yield and benefit of tomato, Spraying 400 ~ 2000 times the trace element water-soluble fertilizer, tomato yield significantly, yield 2.0% to 10.0%. The spraying of 1200 times of water-soluble microelement fertilizers and the spraying of 400 times liquid reached the extremely significant level, of which the foliar spraying 1200 times the highest yield, the average yield of tomato 7079.10kg / 667m2, than spray water treatment yield 648.60kg / 667m2 , Yield increase rate of 10.1%.
