摘要
为引导设施芹菜科学施肥,验证其增产增收效果,对设施芹菜开展了叶面喷施含腐殖酸水溶肥的小区试验。试验以常规施肥为对照(CK)处理,设置喷施清水(T1)和喷施含腐殖酸水溶肥料(T2)2个叶面喷施处理,分别测定了芹菜的生长指标、品质指标和产量。结果表明:T2处理的株高、单株叶片数、单株分蘖数、单株质量均优于CK、T1处理的;与CK、T1处理相比,T2处理的芹菜中硝酸盐含量分别下降了14.50%、6.85%,维生素C含量分别提高了21.88%、18.18%;T2处理的芹菜产量显著高于CK、T1处理的,可获得较好的经济效益。
In order to guide the scientific fertilization of facility celery and verify its effect on increasing yield and income,a plot experiment is conducted on foliar spraying of water-soluble fertilizer containing humic acid on facility celery.The experiments use conventional fertilization as the control(CK)treatment,and set up two foliar spraying treatments:spraying water(T1)and spraying water-soluble fertilizer containing humic acid(T2).The growth indicators,quality indicators,and yield of celery are measured respectively.The results show that the plant height,number of leaves per plant,number of tillers per plant,and weight per plant of T2 treatment are superior to those of CK and T1 treatments.Compared with CK and T1 treatments,the nitrate content in celery treated with T2 decreased by 14.50%and 6.85%,while the vitamin C content increased by 21.88%and 18.18%,respectively.The celery yield of T2 treatment is significantly higher than that of CK and T1 treatments,and better economic benefits can be obtained.
