通过对苹果产区实地调查 ,结合气象资料分析 ,认为 :今年入春以来 ,气温持续偏高 (大部分地区较常年偏高 2～ 3℃ ) ,降水偏少 (较常年偏少五到九成 ) ,春旱明显 ,致使苹果初花期提前 5～ 1 0 d,恰遇 4月 9～ 1 0日、 1 4～ 1 5日两次强冷空气活动 ,以及近 1 0 a不遇的大风、沙尘暴天气 ,使苹果花蕾和花序受到严重冻害 ,并严重阻碍了正常的授粉受精 ,造成大量落花落果。建议在苹果果实膨大期增强防灾意识 ,提高抗灾能力。加强冰雹防御、病虫害防治和果园管理。
Based on the field survey of apple producing areas and the analysis of meteorological data, it is considered that since the spring of this year, the temperature has been continuously high (2 ~ 3 ℃ above normal in most areas) and the rainfall is relatively low (5-9% less than normal years) ), The spring drought is obvious, resulting in apple early flowering stage 5 ~ 10d, just meet April 9 ~ 10 days, 14 ~ 15 twice strong cold air activity, and the last 10 days of no wind, sandstorm Weather, so that apple buds and inflorescences suffered serious frostbite, and seriously hampered the normal pollination, resulting in a large number of flowers. It is recommended to increase awareness of disaster prevention and increase disaster resilience in the period when apple fruit is swollen. Strengthen hail defense, pest control and orchard management.
