摘要
陕西省渭北地区作为苹果种植的优生区,是陕西省重要的鲜食苹果生产基地,同时也是花期冻害的高发区,花期冻害成为影响陕西苹果产量和品质最严重的自然灾害之一。大陆性季风气候决定了黄土高坡会发生非常频繁的气象灾害。为了避免气象灾害,应及时采取有效的措施来预防低温霜冻产生的危害,从而不断提高果园的经济效益。本次通过在盛花期对白水苹果试验站的多个苹果品种进行冻害调查,分析了不同苹果品种花期所受到的冻害程度,并提出几项关键性防冻害措施,以最大限度的降低花期在低温时所受的冻害影响。
Weibei area of Shanxi Province,as a eugenic area for apple planting,is an important fresh apple production base in Shanxi Province,and it is also an area with a high incidence of frost damage during the flowering period.Frost damage during the flowering period has become one of the most serious natural disasters affecting the yield and quality of Shanxi apples.The continental monsoon climate determines that high loess slopes will have very frequent meteorological disasters.In order to avoid meteorological disasters,effective measures should be taken in time to prevent the harm caused by low-temperature frost,so as to continuously improve the economic benefits of the orchard.Through the frost damage investigation of multiple apple varieties in the Baishui area,apple experimental station during the full blooming period,the degree of frost damage received during the flowering period of different apple varieties was analyzed,and several key anti-freezing damage measures were proposed to minimize the low temperature during the flowering period.The impact of frost damage from time to time.
