以玉米和植物光合生物增效剂为试验材料,研究叶面喷施植物光合生物增效剂对玉米产量及干物质积累的影响。结果表明,喷施150 g/hm2和300 g/hm2植物光合生物增效剂对玉米子粒产量增加不显著;喷施450～750 g/hm2植物光合生物增效剂能够显著增加玉米子粒产量,比对照产量提高8.3%～12.0%,主要表现在穗粒数和百粒重显著增加;还能显著提高地上部干物质积累速度和叶片叶绿素含量。以喷施600 g/hm2植物光合生物增效剂增产效果最佳。
The effects of foliar spray photosynthetic bioadjuvant on maize yield and dry matter accumulation were studied using corn and plant photosynthetic bio-synergist as test material. The results showed that spraying 150g / hm2 and 300g / hm2 photosynthetic bio-synergist on maize grain yield increase was not significant; spray 450 ~ 750g / hm2 photosynthetic bio-synergist can significantly increase maize grain yield, than Control yield increased by 8.3% ~ 12.0%, mainly in the grain number and grain weight increased significantly; also significantly increase the aboveground dry matter accumulation rate and leaf chlorophyll content. To spray 600 g / hm2 photosynthetic plant synergist yield the best.
