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。
The effects of spraying different kinds of foliar fertilizer on the chlorophyll content, phenology period, shoot growth and fruit quality of the leaves were studied by using the “Golden Finger” grape with yellowing leaves. The results showed that spraying foliar fertilizer could effectively improve the yellowing status of grape leaves. Compared with the blank control, leaf chlorophyll content of leaves increased faster after foliar fertilizer application, Significantly improved the color of the fruit, earlier maturity, fruit quality was also significantly improved, of which spraying 0.5% N fertilizer + 0.3% FeSO4 treatment effect is the best.
