摘要
本试验以波姬红无花果为材料,在无花果生长季节分别喷施氨基酸水溶肥水溶肥(A)、高钾型大量元素水溶肥(B)、广谱均衡型大量元素水溶肥(C)及钾镁硼锌铁水溶肥(D),研究4种叶面肥对无花果新梢、叶片营养状况及果实品质的影响。结果表明,叶面肥D处理显著促进叶片生长,提高鲜叶重;喷施叶面肥显著提高叶片钙、镁、锌、铁、硒元素含量,对叶片氮、磷、钾含量基本无影响;喷施叶面肥显著提高单果重,叶面肥D处理单果重达80. 35 g,高于对照40. 96%。因此,喷施叶面肥能够显著改善无花果叶片营养状况,提高果实品质。
In order to investigate the effects of different foliar fertilizers on growth and fruit quality of fig(Ficus carica Linn.),four foliar fertilizers such as amino acid foliar fertilizer(A),high K macroelement foliar fertilizer(B),broad spectrum microelement foliar fertilizer(C)and K-Mg-B-Zn-Fe water-soluble fertilizer(D)were applied in growth period of Bojihong fig,and their effects on shoots,leaf nutritional status and fruit quality were analyzed in this study.The results showed that foliar D could significantly promote the leaf growth and increase the fresh leaf weight.The four foliar fertilizers significantly increased the contents of Ca,Mg,Zn,Fe and Se in leaves,but had no significant effect on the contents of N,P and K.The foliar fertilizers could significantly increase single fruit weight.The single fruit weight was 80.35 g under foliar fertilizer D,which was 40.96%higher than that of control.Therefore,foliar fertilizers could significantly promote the leaf nutritional status,and improve the fruit quality.
