The cold air appeared frequently in the spring of 2014 in Ningxia and frostbite weather process appeared many times. In order to understand the comprehensive effect of the late frost hazard on apple in Ningxia this year, the situations of apple late frost hazard in Ningxia are analyzed by using investigation and statistics methods. The results showed that the apple in Ningxia suffered frost both in the flores- cence and young fruit period and the average disaster degrees were from 30% to 35%.The comprehensive late frost hazard was affected greatly by the frequency of the daily minimum temperatures and the extreme daily minimum temperature. The differences among different investigation points were obvious, and in the view of limited investigation points, the Jiaozishan forest farm in Zhongning suffered frost seriously. Among various varieties, the Fuji suffered frost most seriously. The results were helpful to further understanding of the potential risk of the apple industry in Ningxia to suffer frost. |
