如何防止落花、落蕾现象?
如何防止落花、落蕾现象?在家庭花卉养护的过程中,由于管理不善,盆花会出现落花、落蕾的现象。造成落花、落蕾的原因有很多,但主要有以下几方面:
(1)营养积累不足:花卉从开花到结实,需要大量的养分供应,若盆花在营养生长阶段,由于光照不足、气温不宜、肥水不当等原因,造成植株生长衰弱,使植物体内养分积累不够,就满足不了花卉生长发育和开花结实的需要。
(2)环境条件不适:各种不利于植物开花、坐果的环境条件引起落花、落蕾,如花期雨水过多,导致花朵腐烂,使授粉受精不能顺利进行;或长期干旱,水分蒸发过多,盆土积水等原因。
(3)偏施氮肥:在植物营养生长阶段,如果施用氮肥过多,易造成植株徒长,影响植株的花芽分化,使其不能开花,或即使开花,也易造成落花、落果。另外施肥时肥料的浓度不够,不能满足花蕾生长发育的需要,也易造成落花、落蕾。
(4)花、果期水肥施用不当:在植株的盛花期和坐果初期,浇水要减少,施肥应停止,以减少生理性落花、落果,提高坐果率,否则会造成落花、落蕾。
