根据近期气候特点,预计2015年花期前后气候变化较为频繁,同时考虑到2014年暖冬效应对树体生长发育的影响,2015年春季果园管理应重点关注以下几个方面。1及时关注天气变化,预防花期晚霜冻害花期晚霜冻害常常造成苹果等多种果树大幅度减产甚至绝产。因此,采取积极有效的措施预防苹果树晚霜冻害。延迟开花躲避霜冻,方法是早春树干涂白。早春对树干、骨干枝进行涂白,以反射光照、减少树体对热能的吸收,降低冠层与枝芽的温度,可延迟开花。
According to the recent climatic characteristics, it is estimated that the climate change will be more frequent around the flowering stage in 2015, and taking into account the effect of the 2014 warm winter effect on the tree growth and development. The spring orchard management in spring 2015 should focus on the following aspects. A timely attention to the weather changes, the prevention of late flowering frost damage frost late frost damage often caused a large number of apple trees and other fruit trees significantly reduced or even absolute. Therefore, to take active and effective measures to prevent apple tree frost damage. Delay blossom to avoid frost, the method is early spring trunk Tu white. Early spring on the trunk, trunk branches painted white to reflect the light, reduce the body’s absorption of heat energy, reduce the temperature of the canopy and buds, can delay flowering.
