裂果病的发生与品种、温度、光照、空气泣度有关。其中土壤含水量的充足与否,是发生裂果病的重要因素,在正常情况下,苹果果实内的含水量达到85～95%,才能满足其生长发育的需要,如果天气干旱,土壤含水量不足,苹果果皮及果肉部分细胞体积膨大就会受到抑制,若干旱持续发展,会严重影响果皮、果肉细胞体积增大,并导致果皮细
The occurrence of split fruit disease and variety, temperature, light, air pressure on the degree. Soil moisture is sufficient or not, which is an important factor in the occurrence of split fruit diseases. Under normal circumstances, the water content in apple fruit reaches 85-95% in order to meet the needs of its growth and development. If the weather is arid, the soil moisture content is insufficient , Apple peel and pulp part of the cell volume expansion will be inhibited, if the drought continues to develop, will seriously affect the peel, pulp cell volume increases, and lead to thin skin
