摘要：

研究结果表明,野荸荠适宜生长在质地疏松、呈中性、有机质含量较高、长期湿润的连作稻田内。其地下球(块)茎分布较深,具休眠期,萌发最适温度为25～30℃,15 d左右地下茎开始形成,50 d左右为分株高峰期;移栽稻田移栽后7～l0 d发生,15～25d为出草高峰;秧苗移栽后5～7 d发生,10～20 d为出草高峰。地下球茎形成时间较短,8月下旬至9月上旬开始形成,持续到l0月中下旬;球茎不耐干旱、日晒和严寒;在土下,其寿命可保持5 a以上;野荸荠在田间呈核心分布,由核心向四周扩展,远距离传播主要依靠种子。该杂草的防除策略主要为化学防除,以"阔叶亡"拌湿润细土或结合追肥拌化肥撒施,田间保持浅水3～5d,以后恢复正常管理,可以取得理想效果。

摘要：

The study results showed that Heleocharis plantagineiformis prefer to grow in the continuous cropping paddy-fields where have long-term moist and neutral soils with loose texture and high organic matter content;its corm distributes deeply and has dormancy stage;the optimum temperature for its germination is 25～30℃,its corm starts to grow at 15 d,and its ramet peak period is around 50 d;it emerge at 7~10 d after transplanted to paddy-field,and the peak of weed growth is at 15~25 d;it emerge at 5~7 d after seedlings transplanted,and the peak of weed growth is at 10~20 d.The corm of Heleocharis plantagineiformis has short developing time,it start to grow at late August to early September,and lasting to mid-late October;it is not tolerant of drought,solarization and chilliness,and its life can be kept for over 5 a under ground.Heleocharis plantagineiformis showed a contagious distribution in field that expanding from core to around and its long distance dissemination mainly relies on seeds.The control strategy for this weed mainly is chemical control that mixing Kuoyewang with moist fine soil or combing with broadcast application of mixing top dressing with chemical fertilizer,meanwhile keeping shallow water in field for 3~5 d,then resuming to the normal management can obtain ideal effect.
