摘要

Using the data at standard ground observation field of Lingyuan Meteorological Bureau and comparative and parallel observation data during growth period of surrounding Prunus sibirica var suavosperma,and combining social investigation data about low-temperature cold injury loss of P.sibiricain recent years,it is found that low-temperature cold injury and abrupt change of temperature in spring are also important factors affecting P.sibiricayield and economic benefit.According to temperature indexes,meteorological department timely issues warning and forecast,and relevant departments and foresters take corresponding preventive measures,and strengthen cultivation technology and management of P.sibiricapark.It avoids economic loss of P.sibiricacaused by low-temperature cold injury,and obtains high and stable yield.
