摘要
以产生叶片黄化的"金手指"葡萄为试材,研究喷施不同的叶面肥对其叶片叶绿素含量、物候期、枝梢生长量及果实品质的影响。结果表明:喷施叶面肥能有效地改善葡萄叶片黄化状态,与叶面喷水空白对照相比,叶面喷施叶面肥后植株的叶片中叶绿素含量增长更快,枝梢生长量显著提高,果实转色、成熟期更早,果实品质也显著提高,其中以喷施0.5%N肥+0.3%FeSO4的处理效果为最佳。
In order to reveal the effects of different foliar fertilizer on the leaf yellowing of‘Gold Finger＇grape,four kinds of foliar fertilizers were sprayed.The results showed that compared with control group,spraying the foliar fertilizers on the leaf yellowing of‘Gold Finger＇grape could increase the chlorophyll content and shoot growth,the fruit growth period was promoted,and the fruit quality was significantly improved.Among the research,spraying 0.5%N＋0.3%FeSO4 was the best.
