葡萄树伤流影响其生长发育，据试验，当土壤温度达到7－9℃时，一枝葡萄蔓一昼夜可流失树液630ml，每升伤流液中含还原糖3．sg、多糖0．359、氮0．049、磷0．of3g、钾0．3569、钙01489以及微量的铁、植物生长素、赤霉素和激动素等。伤流严重时可导致树体衰弱甚至死树，防止葡萄
Vine injury affects its growth and development, according to the test, when the soil temperature reaches 7-9 ℃, a vine vine may be a day and night flow of tree liquid 630ml, every liter of wound fluid containing reducing sugar 3. sg, polysaccharide 0.359, nitrogen 0.049, phosphorus 0. of3g, potassium 0.3569, calcium 01489 and traces of iron, auxin, gibberellin and kinetin. Serious injury can lead to tree debilitating or even dead trees and prevent grapes
