4)防止落花落荚:落花落荚的原因主要是:①温度过低或过高。高温(35℃以上)或低温(15℃以下)影响花芽的正常分化,使花器发育不良而出现不孕花,引起落花落荚。②营养不足。开花期的落花是由植物体营养生长和生殖生长营养供应发生矛盾所致;中期是由花与花、花与荚、荚与荚之间的养分激烈争夺所致,另外,同一花序中由于营养物质的分配不均也可引起落花落荚。③湿度太高或太低。湿度的高低影响花粉的发芽力,在低温、低湿的条件下影响较小,在高温、高湿或高温干旱时影响较大。若遇高温、高湿,柱头表面的黏液失去对花粉的萌发诱导作用;高温干旱又会使花粉发育畸形,失去生活力。④光照不足,通风不良。豆角对光照强度很敏感,尤其在花芽分化后,当光照强度弱时,同化效率低,落花、落荚数增多。若栽培密度过大,或支架不当,植株下部郁闭,不仅光照不足,而且通风不良,因而下部落花、落荚比上部更多。可采取如下预防措施:①选用适应性广、抗逆性强、坐荚率高的优良品种,如农大丰收一号豆角、农大丰收三号豆角,适期播种,使盛花期能避开高温季节。②栽培密度恰当,采用适当的搭架方式,或与矮生作物间作,如菜心、小白菜、花椰菜等,创造良好的通风透光环境,改善光照条件。③加强肥水管理,合理配合施用氮、磷、钾肥,掌握花前少施、花后多施、结荚盛期重施的原则。④及时采收嫩荚,节省养分消耗。⑤及时防治病虫害,保持植株健壮。⑥喷施植物生长调节剂,例如氨基酸糖磷脂,可减少落花落荚,提高结荚率。
