根据观察,秋冬季节新栽的果树闷芽原因如下:一是果苗出置和移栽时,造成伤根过多或无细根苗,定植后吸收水分和养分困难,造成树苗地上茎芽和地下根系生理机能失调。二是栽植园地下水位较高,或浇水较多,降低了土壤温度,以致影响树苗发根并推迟发芽。三是栽植时埋茎过深,造成树苗根系缺氧,延缓根系生长。四是定干整形修剪时.留下的是弱芽和隐芽,造成发芽慢。总之闷芽是由于新栽果树根系生长与茎芽发育不平衡造成的。
According to the observation, the autumn and winter planting of new fruit trees because of the following reasons: First, when the seedlings are placed and transplanted, resulting in excessive roots or no fine root seedlings, moisture and nutrient absorption after planting difficulties, resulting in saplings on the ground shoots and underground roots Physiology Dysfunctional Second, the plantation ground water level is higher, or watering more, reducing the soil temperature, resulting in affecting seedling hair roots and delayed germination. Third, planting buried Burnet too deep, resulting in seedling root hypoxia, delayed root growth. Four is scheduled to dry plastic pruning left behind is weak buds and hidden buds, resulting in slow germination. In short stuffy bud is due to the new planting fruit tree root growth and stem imbalance caused by imbalance.
