摘要
非结球芽甘蓝在生育期内可多次发生缺钙症,明显影响产量。研究发现,暴雨、干旱等不良气候对其发生有显著影响,且与品种、生育期和施肥等有关。防治非结球芽甘蓝缺钙症可在植株开展度达到60～70cm(叶片数达到30片左右)即进入旺盛生长期后开始,喷施钙肥防治缺钙症,隔7～10d1次,连喷2～3次。
Acalcerosis was occurred many times in the period of growth of non-corm brussel sprouts, and significantly affected productions. The research revealed that occurrence of acalcerosis was affected greatly by the bad climate such as rainstorm, drought, and Was correlated with variety, the period of duration and fertilizer. When plants′ unfolding leaf wideness was 60-70 cm （the numbers of leaves were 30 or so）, and the plants were in the exuberant period, Ca fertilizer was soraved for 2-3 times to control acalcerosis, one time per 7-10 d.
