Kyoho grape splits occur during ripening of berries, mainly due to rapid changes in water content in the soil. Fruit particles absorb water through the fruit surface and roots, produce a large turgor pressure in the fruit, and crack from the weak parts of the peel to form fruit cracks. In addition, cracking is also caused by the increase in expansion pressure in the fruit due to cultivation conditions and climate change. Improve the soil by deep plowing, supplementing organic matter and other methods to ensure stable root water absorption, with particular attention to adjusting the water balance of the Kyoho grape during its hard-core and coloring phases. During the dry period, especially during the dry period after the rainy season, timely watering is needed to keep the soil at a certain moisture content (about 60%). During the rainy season, drainage work can be done through open channels and culverts to ease the changes in soil moisture. Covering the groundwater film while covering the groundwater film can prevent excessive rainfall on the one hand, and on the other hand, it can suppress evaporation of soil moisture and reduce soil moisture changes. When the ear bagging fruit is ripe, the ear is bagged to prevent the pericarp from absorbing water, which can significantly reduce the rate of cracking of the ear. Strengthen the management of production should strengthen the cultivation and management, in the premise of ensuring the growth of the tree robust, do a good job in summer shear, so that the distribution of the ears reasonable.
