含腐植酸水溶肥在芹菜上的应用效果

Application Effect of Water-soluble Fertilizer Containing Humic-acids on Celery

通过在大棚芹菜上喷施含腐植酸水溶肥的肥效试验表明,在大棚芹菜上喷施含腐植酸水溶肥可以明显改善芹菜生物学性状,提高芹菜的产量和经济效益。叶面喷施含腐植酸水溶肥与同期喷施等量清水比,增加了芹菜的株高、叶柄长、叶柄厚和单株重,每667 m^(2)平均增产141.41 kg,增产率6.96%,产量差异达显著水平。收入净增率达到5.68%,经济效益显著。

A water-soluble fertilizer containing humic-acids were tested to find the fertilizer effect on celery in greenhouse.The results showed that spraying the water-soluble fertilizer containing humicacids could obviously improve the biological characteristics of celery,increase the yield and economic benefit.Compared with the same amount of spraying water at the same period,the water-soluble fertilizer containing humic-acids could increase the plant height,petiole length,petiole thickness and average single plant weight of celery.The average yield significantly increased 6.96%(141.41 kg/667 m^(2)),which brought 5.68%net economic benefits increase.
