缓控释肥、复合肥对芹菜产量的效应初报

Effects of Slow and Controlled Release Fertilizer and Compound Fertilizer on Yield of Celery

为促进"减量施肥"和缓控释肥在蔬菜上的推广应用,以缓控释肥、复合肥为试验材料,常规用肥(尿素+过磷酸钙+硫酸钾)作对照,采用随机区组试验方式,研究了2种肥料对芹菜农艺性状和产量的影响。结果表明:缓控释肥可持续释放营养以满足芹菜对养分的需求,与常规用肥相比,每667 m^(2)芹菜产量显著增加,达到6 261.47 kg,增产率为51.45%;单株鲜质量、干质量分别增加51.98%、50.8%,均达显著差异水平。复合肥效果不显著。

In order to promote the popularization and application of "reducing fertilizer" and slow and controlled release fertilizer on vegetables,the effects of two kinds of fertilizer on agronomic characters and yield of celery were studied with slow/controlled release fertilizer and compound fertilizer as materials in random block test,conventional fertilizer[CO(NH_(2))_(2)+Ca(H_(2)PO_(4))_(2)+K_(2)SO_(4)]was used as control.The results showed that slow and controlled release fertilizer could continuously release nutrients to meet the nutrient requirement of celery,the yield reached 6 261.47 kg per 667 m^(2) with a significant increase by 51.45% compared with the conventional fertilizer,fresh and dry weight per plant increased significantly by 51.98% and 50.8%,respectively.The effect of compound fertilizer was not significant.
