1　产生裂果的原因1 .1　水分供应不均 ,果皮组织脆弱　在葡萄幼果期到硬核期之间 ,当土壤水分由湿润急剧变化为干燥时 ,若着色期遇雨和灌水 ,果粒通过根系、果面吸收水分会迅速增大 ,使果粒中的膨胀压增加 ,从果皮薄弱部位裂开形成裂果。一般果粒顶部和果蒂部易开裂 ,特别是奥 1 reasons for the split fruit 1 .1 uneven supply of water, the pericarp tissue is fragile in the young grape period to the hard core period, when the soil moisture changes rapidly from wet to dry, if the staining period of rain and irrigation, fruit through Roots, fruit surface absorption of water will rapidly increase, so that the expansion of the pressure in the fruit increased from the pericarps cracked the formation of weak parts of cracking. The top of the general fruit and fruit pedicle easy to crack, especially Austria
