腐植酸水溶肥在大棚芹菜上的肥效试验

为了研究济农腐植酸水溶肥在大棚芹菜上的肥效试验,采用不同稀释倍数（800倍、1000倍、1200倍）的济农腐植酸水溶肥对大棚芹菜进行叶面喷施,以磷酸二氢钾与尿素混合水溶液及清水喷施做对照,观察不同处理对大棚芹菜生物性状的影响。结果表明,与对照组相比,济农腐植酸水溶肥可以明显改善作物性状,提高作物的产量和经济效益。其中,以叶面喷施800倍液和1000倍液济农腐植酸水溶肥两组处理效果最为明显,株高增加0.8-2 cm,茎粗增加0.2-1.0 cm,单株重增加0.01-0.03 kg,小区产量提高8.99%-10.89%,经济效益显著。因此,济农腐植酸水溶肥在芹菜及其他蔬菜上有广阔的推广应用前景。

Effect of Jinong Humic Acid Water Soluble Fertilizer on Greenhouse Celery

The effect of Jinong humic acid water soluble fertilizer on greenhouse celery was studied. Different dilutions of Jinong humic acid water soluble fertilizer, composed of potassium dihydrogen phosphate and urea, were sprayed on greenhouse celery and water was used as control, respectively. The result showed that compared with CK, Jinong humic acid water soluble fertilizer could improve the quality, output and biological characters of greenhouse celery. Especially the treatments of 800 times and 1000 times could increase growth plant height by 0.8-2 cm, adding stalk width by 0.2-1.0 cm, raising plant weight by 0.01-0.03 kg and increasing the yield by 8.99%-10.89%. It showed that Jinong humic acid water soluble fertilizer has wide application prospect in celery and other vegetables.
