马铃薯蕾期管理五要素

        一、及时中耕 马铃薯现蕾后,一定要加强中耕,进行浅锄土,随中耕实行高培土,培土高达15-20厘米。
  二、适当追肥 对植株矮小、黄弱的马铃薯苗田应追施氮肥,每亩施尿素5千克,逐株追施;对植株生长旺盛的田块,应施磷钾肥为主,亩施磷肥15千克和草木灰,或施复合肥15-20千克。
  三、及时打顶 马铃薯现蕾以后马上进入开花期,要消耗大量养分。为避免这种无效消耗,应及早打顶并把花蕾摘掉。
  四、根外喷肥 现蕾期应选择晴天下午进行根外喷肥,喷施0.3%磷酸二氢钾和0.3%硫酸锰混合液,或用15%多效唑可湿粉剂150克加水15千克,搅拌均匀后喷施,亩喷施药液50千克,可使马铃薯植株矮化三分之一,叶色变浓绿,加强光合作用,增加大薯比例。全田喷一次0.3%-0.5%高锰酸钾溶液,可防马铃薯黑茎病、病毒病。
  五、防治病虫 马铃薯进入现蕾期,田间生长郁蔽,容易出现高湿环境,导致发生疫病。一旦发生中心病株应喷药防治,可用硫酸铜、百菌清、瑞毒霉等杀菌剂。马铃薯也易受到瓢虫危害,可用氧化乐果800倍液喷雾消灭。
