果实膨大期施用黄腐酸水溶肥对苹果叶片生长、果实品质及产量的影响
Effects of Applying Water-Soluble Fulvic Acid Fertilizer during Fruit-Swelling Period on Apple Leaf Growth,Fruit Quality and Yield
摘要
Abstract
Seven-year-old apple trees of Yanfu3 /M26 /Malus hupehensis were used as materials in the experiment. Four fertilizer treatments as 0. 7 kg N-P-K compound fertilizer (CK), 1. 0 kg water-soluble yellow humic acid fertilizer (H1), 1. 5 kg water-soluble yellow humic acid fertilizer(H2) and 2. 0 kg water soluble yellow humic acid fertilizer(H3) were set for single plant. Their effects on leaf growth, fruit quality and yield were studied. The results showed that the H1, H2 and H3 increased the chlorophyll content, leaf area and hundred-leaf weight compared with CK. The corresponding increase ranges reached 10. 40％ ～ 16. 08％, 2. 90％ ～ 6. 21％ and 14. 63％ ～ 23. 80％, and that of H3 was the highest. H1, H2 and H3 improved the internal and external fruit qualities. The single fruit weight, firmness, vertical diameter, transverse diameter, soluble solid and the ratio of soluble solid to acid increased by 7. 19％ ～ 27. 26％, 19. 60％ ～ 43. 13％, 8. 23％ ～ 19. 77％, 1. 96％ ～ 6. 52％, 5. 98％ ～ 18. 48％ and 22. 19％ ～ 30. 36％ respectively. H3 also had the best effects. H1, H2 and H3 increased the yield per plant by 6. 15％ ～ 25. 89％ compared to CK. By comprehensive analysis, it was concluded that water-soluble yellow humic acid fertilizer could not only influence leaf growth, but also improve fruit quality and yield of apple, and 2. 0 kg water soluble yellow humic acid fertilizer per plant was the best application amount.关键词
