所谓果树闷芽,是指新栽的果树,已进入到春季的3—4月份仍不发芽,但它既不干梢,也不皱皮,这种现象称为闷芽。造成闷芽的原因大致有以下几点:一是果树苗木移栽时伤根过多,尤其是须根太少,定植后不易吸收水分和养分,造成地上部分和地下部分生理机能失调;二是定植地的地下水位高,或浇水较多,降低了土壤温度,以致影响发根并推迟发芽;三是栽植过深,使土壤中根系缺氧而不利于根系生长;四是定植整形修剪的部位不合适,留下了弱芽和隐芽。
The so-called fruit tree stuffy bud, refers to the newly planted fruit trees, has entered into the spring 3-4 months still does not germinate, but it neither dry nor wrinkled skin, a phenomenon called boring. The causes of nausea buds are generally the following: First, excessive transplanted fruit tree seedling roots, especially fibrous roots too few, difficult to absorb moisture and nutrients after planting, resulting in aboveground and underground physiological dysfunction; Second, planting Groundwater level is high, or watering more, reducing the soil temperature, so affect the hair root and postpone germination; Third, planting too deep, so that the root anoxia soil is not conducive to root growth; Fourth, the site of plastic planting pruning Inappropriate, leaving the weak buds and hidden buds.
