目前有些果园由于园址选择不当,或遇早春低温回潮,往往容易引起花芽受冻,致使减产.为避免或减轻霜冻,现介绍防止花期冻害的几个措施,以期获得更大的经济效益.1.延迟发芽.发芽迟则开花期晚,有可能避免终霜期或减轻霜冻危害程度.①春季灌水.春季多次灌水能降低上温 At present, some orchards due to improper site selection, or early spring low temperature resurgence, often easily lead to flower buds frozen, resulting in reduced production. In order to avoid or reduce the frost, we will introduce some measures to prevent frost damage in the flowering period with a view to gain greater economic benefits. 1. Delay germination. Late blooming late flowering, it is possible to avoid the final frost or reduce the extent of frost damage. ① spring irrigation. Multiple irrigation in spring can reduce the temperature
