秋白梨褐痘病是一种重要的贮藏期病害。经1994—1996年系统地研究,明确了该病系由高氨、低钙和钙、氮比失调所致的生理病害;采收后果实淋雨,预贮期和贮藏前期温度过高,入库晚、预贮期长,预贮及贮藏前期果实衰老快,均有利于发病。采取增施农家肥,追施氮、磷、钾、钙、硼复合肥,生长期对面和果实喷施钙、硼液,采后短期预贮“发汗”,及时低温贮藏等综合措施,可有效地防止该病的发生。
Autumn white pear brown pox disease is an important storage disease. After 1994-1996 systematic study, the disease was identified by high ammonia, low calcium and calcium, nitrogen imbalance caused by physiological diseases; fruit after harvest rain, pre-storage and pre-storage temperature is too high, into Library late, long pre-storage, pre-storage and pre-storage fruit aging fast, are conducive to the incidence. The comprehensive measures such as adding farmyard manure, topdressing nitrogen, phosphorus, potassium, calcium and boron compound fertilizer, spraying calcium and boron solution on the opposite side and fruit during the growing period, short-term pre-storage “sweating” To prevent the occurrence of the disease.
