摘要
在大田栽培条件下,研究了不同叶面肥(尿素、磷酸二氢钾、氨基酸与钙镁锌硼铁肥)配施对徐蒜917生长及鳞茎产量与品质的影响。结果表明:喷施叶面肥都能不同程度提高大蒜叶片叶绿素含量及叶片SOD、POD与CAT酶活,提高鳞茎维生素C、可溶性蛋白、可溶性糖含量与大蒜产量,磷酸二氢钾+钙镁锌硼铁肥复配处理可显著改善鳞茎品质,提高鳞茎产量。
A pot experiment was carried out with garlic cv.Xusuan 917 to study the effects of different foliar fertilizer combination treatments on growth,activity of protective enzymes in leaves,quality of bulbs and yield of garlic.The results showed that the different foliar fertilizer combination treatments could not only enhanced chlorophyll content and the activity of protective enzymes in garlic leaves,but also increased the yield and contents of VC,soluble sugar,soluble protein in garlic bulbs.Among the different combinations of foliar fertilizers,the treatment of KH2PO4+Ca,Mg,Zn,B,Fe had the most optimum results increasing yield and improving bulb quality.
