金橘挂果期的管理方法
金橘挂果期的管理方法,开花时应适当疏花,每枝留花蕾2~3个,同一叶腋内,有时抽生2~3个花芽,选留一个。
花期浇水要比通常偏少,不要太大或过少,否则易引起花蕾脱落。花期要防止雨淋,也不要向正在开放的花朵上喷水。雨水会冲走雌蕊柱头上的黏液,不利于雄蕊花粉的萌发,同时柱头上长期有水滴,易引起柱头腐烂,因此,在花期禁忌花蕾遭受雨淋。结果初期同样要注意浇水适量,待幼果稳坐后,才可增加喷水量。同时注意追肥,幼果期仍可每周浇矾肥水1次,立秋后每盆可追肥饼肥30~40克。
以后要及时抹除秋梢,不使二次结果。为保证果实发育良好,防止干瘪和出现病斑,立秋以后,每隔1周左右,喷洒1次烟梗水(将50克烟梗揉碎,加水1 000~1 500克,浸泡一昼夜,过滤后用家庭卫生喷雾器喷洒),可预防病害,促进果实生长,使叶色翠绿。
在正常情况下,立冬以后果实逐渐变黄,若早熟而落果,可用尿素与过磷酸钙混合做根外追肥。在陈列之前,应除去小果、病果,并修整树冠,将遮果、无果的枝条适当剪除,使果实显露,增加观赏价值。
