腐植酸液体叶面肥对保护地菜豆产量与品质的影响

Effects of Humic Acid Liquid Foliar Fertilizer on Yield and Quality of Greenhouse Beans

采用大棚小区随机区组设计,研究了不同浓度腐植酸液体叶面肥对"将军一点红"、"紫花油豆"产量和品质的影响,以期为菜豆合理使用腐植酸液体叶面肥提供科学依据。结果表明:腐植酸液体叶面肥最佳喷施浓度为600倍时菜豆产量较对照显著增加,"紫花油豆"增加11.6%,"将军一点红"增加9.8%;腐植酸液体叶面肥可显著改善菜豆品质,其中可溶性糖、维生素C及粗蛋白含量增加显著,硝酸盐含量较CK相比"紫花油豆"降低了26.3%,"将军一点红"降低了25.6%。

The effects of different concentrations of liquid humic acid foliar fertilizer on yield and quality of two varieties of beans ‘Zihuayoudou’ and ‘Jiangjunyidianhong’were studied to provide scientific base for applying liquid humic acid foliar fertilizer reasonably in quality vegetables planting by randomized block design with three replications in greenhouse. The results showed that 600 times of dillution was the most effective among all concentrations of liquid humic acid foliar fertilizer. The yield increased significantly in the two kinds of beans,‘ Zihuayoudou’ was 11.6 %, ‘Jiangjunyidianhong’ was 9.8%. The quality was improved significantly. The content of soluble sugar, VC and protein content increased significantly. The contents of nitrate in the two varieties of beans was declined in the concentration of 600 times of dillution, ‘Zihuayoudou’was 26. 3%, ‘Jiangjunyidianhong’ was 25.6% respectively.
