硅肥的抗旱增产作用

RESEARCHES ON THE ACTIONS OF ANTI-ARID AND YIELD INCREASE OF SILICATE FERTILIZER

为了探讨硅肥对玉米的增产作用 ,进行了玉米合理施用硅肥的定位试验研究 ,结果表明 ,硅肥的施用促进了玉米的生长发育 ,增强了光合作用 ,提高了光能和水分利用率 ,达到了抗旱、增产的目的 ,并且提出施硅量以 5 0 0～ 75 0kg/hm2

For the sake of probing into the yield increase action of silicon to maize,the locational experiment of the rational application of silicate fertilizer was conducted.The research deemed the following:The application of silicate fertilizer promoted the growth of maize,strengthened the photosynthesis,increased the utilization rate of light energy,mode high the utilization rate of soil moisture and rain,therefore the application of silicate fertilizer attained the goal of anti-arid and yield increase,and the research put forward that the application amounts of 500～750 kg/hm 2 of silicate fertilizer were the best.
