摘　　要：在杂交水稻抽穗10 % 、50 % 和80 % 时,喷施浓度为100 mg/kg 花信灵1 ～2 次,能延缓功能叶衰老、增强光合能力、提高结实率、增加粒重,获得显著的增产效果-Huaxinglin solution(100 mg/kg) was sprayed on hybrid rice once or twice in different heading stages. The results were that senescence of rice flag leaves was put off and the rice has a higher photosynthesis rate,higher setting percentage and greater per_seed_weight. Its output was obviously increased.
