摘要
为对比施用水溶性肥料与传统硫基肥料在芹菜上的不同肥料效果,通过设置大棚肥效试验,对史丹利20-20-20大量元素水溶性肥料、尿素、15-15-15硫基肥在芹菜上的施用效果进行研究。结果表明,追施史丹利20-20-20水溶肥处理的芹菜株高在整个生长期内均为最高,最后收获时,比追施尿素处理的株高增加12.9%、比追施15-15-15硫基肥处理的增加4.0%;追施史丹利20-20-20水溶肥处理的芹菜鲜重、理论产量显著高于其他处理,理论产量比追施尿素处理的增加81.7%、比追施15-15-15硫基肥处理的增加15.7%;追施史丹利20-20-20水溶肥处理的芹菜经济收益亦为最高,比追施尿素处理的收益增加36765元/hm2、增收率达98.7%,比追施15-15-15硫基肥处理的收益增加9840元/hm2、增收率达15.3%。研究表明,施用水溶性肥料成本投入较大,但其效益最高。
In order to compare the fertilizer efficiency of water soluble fertilizer and traditional sulphur basedfertilizer,greenhouse experiments were conducted to study the effects of 20-20-20 water soluble fertilizer ofStanley,urea and 15-15-15 sulfur fertilizer on celery.The results showed that the celery plant height was thehighest under the 20-20-20 water soluble fertilizer of Stanley treatment during the whole growth period,andwhen harvested,the plant height was 12.9% and 4.0% higher than those under urea and 15-15-15 sulfurfertilizer treatments,respectively.The fresh weight,theoretical yield of celery treated by 20-20-20 watersoluble fertilizer of Stanley were significantly higher than those of other treatments,the theoretical yield was81.7% higher than that under urea treatment,and 15.7% higher than that under 15-15-15 sulfur fertilizertreatment.The economic income of celery treated by 20-20-20 water soluble fertilizer of Stanley was also thehighest,increased 36765 yuan/hm^2 than urea treatment（increase rate was 98.7%） and increased 9840 yuan/hm^2 than 15-15-15 sulfur fertilizer treatment（increase rate was 15.3%）.The results indicate that although theapplication of water soluble fertilizer costs greatly,its efficiency is also the highest.
