    摘要:

    在南京市傅家边农业科技园的梨园研究套袋与不套袋的情况下,氨基酸螯合中微量元素肥料对新高梨品质的影响。结果表明:套袋与不套袋条件下,与对照及有机肥处理相比,施用氨基酸螯合中微肥均能显著增加果实的单果重,显著降低果实中的可滴定酸含量;套袋结合施用氨基酸螯合中微肥,新高梨的果形指数显著大于对照及有机肥处理;施用低水平的氨基酸螯合中微肥能显著提高套袋果和未套袋果果实的Vc 含量,施用量增加一倍时,Vc 含量则有所降低;氨基酸螯合中微肥处理对果实可溶性固形物含量的影响不显著。总的来说,施用低水平的氨基酸螯合中微肥对新高梨品质的改善效果尤佳。

    Abstract:

    Effects of amino acid chelated middle-micro element fertilizer on quality of Niitaka Pear were studied in the pear orchard of Nanjing Fujiabian Agricultural Science and Technology Garden, where the tested pear fruits were divided into two group treatments:one was bagged with special paper bag and the other no-bagged. The results showed that under both bagging and no-bagging conditions, applying amino acid chelated middle-micro element fertilizer significantly increased the individual fruit weight and decreased content of titratable acidity in fruit. After applying organic fertilizer combined with amino acid chelated middle-micro element fertilizer,the fruit shape index of Niitaka Pear significantly improved as compared to control and organic fertilizer treatments under bagging condition. Vitamin C contents of the fruits under both bagged and no-bagged conditions obviously increased by application of amino acid chelated middle- micro element fertilizers at a lower level, while decreased as application rate doubled. There were no significant differences in soluble solids between different treatments with or without amino acid chelated middle-micro element fertilizer. In general, applying amino acid chelated middle-micro element fertilizer at a lower level had a better effect in improving quality of Niitaka Pear.
