腐植酸灌溉肥对温室黄瓜质量及土壤理化性状影响的研究

试验表明，腐植酸灌溉肥和常规化肥处理黄瓜产量分别比对照增加29．72％和22．91％，两个处理之间差异不明显；不同肥处理对黄瓜生物性状影响明显，两个处理间腐植酸灌溉肥略好于常规施肥；不同处理提高了黄瓜中Vc、水溶性糖含量，改善黄瓜品质，腐植酸灌溉肥处理明显好于常规化肥；不同处理均增加了土壤中有机质、碱解氮、速效磷、速效钾含量，为作物生长发育提供了更丰富营养物质，两个处理之间差异不明显。对土壤物理性质影响腐植酸灌溉肥处理明显好于常规化肥。

Study on irrigation fertilizer made from Humic Acid acting on quality of Cucumber in greenhouse and physical and chemical character of soil

The experiment showed:There was no big difference in cucumber production between irrigation fertilizer and general chemical fertilizer when they were acting on cucumber,while they could improve cucumber production by 29.72 percent and 22.91 percent respectively contrast to control experiment.The two kinds of fertilizers could influence the biologic characters of cucumber obviously,and the irrigation fertilizer made from humic acid was a little better than general chemical fertilizer;Both improved content of Vc,water soluble sugar and quality of cucumber,while the former was obviously better than the latter;Both improved content of organic matter,alkaline hydrolysis nitrogen,quick result phosphor and quick result potassium,and provide more abundant nutriment for growth of crop,while there was no big difference between them.As for physical and chemical characters of soil,the former was better than the latter obviously.
