摘要
为了摸清调环酸钙5%泡腾片对水稻生长的影响,以五优稻四号为材料进行了田间大区比较试验,结果表明:在水稻分蘖末期茎叶喷施21～24 g/667 m2的调环酸钙5%泡腾片制剂量可显著缩短穗下第4、第3节间长,增加穗实粒数,对水稻生长安全,且具有防止水稻倒伏和增加水稻产量的双重功效。
Field trials show that: Prohexadione Calcium 5% PP at the end of tillering to stem and leaf spray treatment,the growth of rice security,can significantly reduce the spike under the fourth,three lengths between the increased real grains,rice has to prevent lodging and the dual effect of increasing rice production,appropriate amount of 21~24 g/667 m2(active ingredient dosage 15.75~18.00g ai/hm2).
