2003年晚稻在荔浦县进行的试验结果表明,在早稻收割后第5天(即再生稻和落粒谷苗已长出)喷施农民乐747,喷药后间隔6~7 h回水抛秧,或收割早稻后当天每公顷施750 kg碳酸氢铵和375 kg钙镁磷肥封杀再生稻和落粒谷并作基肥,第2天回水泡田,第5天抛秧,这2个处理对再生稻和落粒谷苗有较显著的防除效果,并取得较好的产量。早稻收割后第5天喷药,当天回水抛秧处理每公顷产量6 570 kg,比收割早稻后当天喷药,第2天回水,第5天排浅水抛秧处理增产697.5 kg/hm2,增长11.88%。 The results of late 2003 rice trial in Lipu County showed that farmers’ music 747 was sprayed on the fifth day after the early rice was harvested Seedlings, or 750 kg ammonium bicarbonate and 375 kg calcium magnesium phosphate fertilizer per hectare on the day after harvesting of early rice, blocking regenerating rice and falling grain valley and basal fertilizer, returning water blisters on the second day and throwing seedlings on the fifth day, these two treatments The ratooning rice and milled grain seedling have more significant control effect and get better yield. Early rice was sprayed on the fifth day after harvesting and returned to the watering and throwing seedlings at the same day. The yield per hectare was 6 570 kg, which was higher than that on the day after harvesting the early rice, returned on the second day, and increased by 697.5 kg / hm2 on the fifth day, Increase by 11.88%.
