不同复合肥处理对芹菜农艺性状的影响

Effects of Different Compound Fertilizer Treatments on Agronomic Characters of Celery

为验证不同复合肥的肥效,开展了田间小区试验。试验以芹菜为对象,共设置了常规复合肥、单宁复合肥、腐殖酸复合肥等3个处理,每个处理重复3次,通过调查不同生长发育期的芹菜农艺性状来考察不同复合肥对芹菜产量的影响。结果表明:腐殖酸复合肥较常规复合肥可显著提高芹菜的分蘖数和产量;单宁复合肥在芹菜生长发育前期作用效果较明显,随生育期推进,其肥效与常规复合肥的无明显差异。

In order to verify the fertilizer efficiency of different compound fertilizers, field plot experiment is being carried out. Celery is taken as the object in this experiment, and three treatments including conventional compound fertilizer, tannic compound fertilizer and humic acid compound fertilizer are taken. Each treatment is repeated for three times. The effects of different compound fertilizers on celery yield were researched by investigating the agronomic characteristics of celery at different growth stages. The results show that comparing with conventional compound fertilizer, humic acid compound fertilizer could increase the tiller number and yield of celery significantly;tannic compound fertilizer had obvious effect on the early stage of celery growth and development, yet there is no significant difference between tannic compound fertilizer and conventional compound fertilizer as the growth period progressed.
