鸭梨在贮存过程中发生黑心病是由多种因素造成的。经调查研究和反复试验证明,在我们这个地区,鸭梨贮存期间果窖内温度偏高、相对湿度偏低和通风条件不良,是造成黑心病的主要原因。鸭梨出现黑心病时期的早晚及严重程度,主要取决于果实内部物质转化的快慢,即果实后熟和老化过程的快慢。而其内部变化又与窖内温度高低、湿度大小、通风条件好坏紧密相关。 Pear black heart disease occurs during storage is caused by many factors. The investigation and trial and error proved that in our region, the temperature in the cellar during the storage period of pear in our area is relatively high, the relative humidity is low and the ventilation conditions are not good, which is the main cause of black heart disease. The occurrence of black heart disease in pear sooner or later and the severity depends mainly on the speed of transformation of fruit internal matter, that is, the fruit ripening and aging process. And its internal changes and pit temperature level, humidity, ventilation conditions are closely related.
