摘要
1998~2001年进行了玉米合理施用硅肥的田间定位试验研究。结果表明:施用硅肥促进了玉米生长发育,增强了光合作用,提高了光能利用率和水分利用率,达到了节水、抗旱、增产的目的。在一般干旱年份,硅肥用量以500~750kg/hm2为佳,在特旱年份以250kg/hm2左右为宜。
During 1998~2001,the field experiments of application of silicate fertilizer to maize were conductedThe results showed:The application of silicate fertilizer promoted the growth of maize,strengthened the photosynthesis,increased the utilization rate of light energy and soil moisture ,therefore the application of silicate fertilizer attained the goal of water saving,anti_arid and yield increase.In generally dry year,the application amount of silicate fertilizer of 500~750 kg/hm2 were better,but in specially dry year,the application amount of silicate fertilizer of 250 kg/hm2 was appropriate
