如何防止风对花的危害?
①当有大风吹来时,应将抗风力不强或幼苗嫩株移至背风处或室内放置。如有花木被吹倒,应立即扶起,减轻花木的受损程度,促使其生理代谢功能迅速恢复正常。
②平时对花木应进行实当的修剪,以控制花木的高度和枝叶的密度,从而减轻其对风的阻力,减少风对花木的危害。
③在风多、风强的地方,应选择冠幅较小、植株较矮且抗风能力强的花木。不宜选用冠幅大、枝态细长的植物,以免被风吹折、吹倒,不利其生长。
④遇到大风天气,不宜给花卉植株浇水,以免土壤遇水松软,植株稳固性不好,易被风吹倒。
⑤花木立地土壤应保持透水、透气,避免土壤潮湿根系发育不良,当大风来时,引起伤害。
⑥在多风且风力强的地区,对花木施肥时应控制氮肥的用量,以免引起植物枝叶徒长,茎基部组织细弱,遇风就易被吹折。
⑦在植株上盆、移盆、扦插、定苗时,应将其栽稳,覆土盖实,以防止或减轻风对其的危害。
