Physiological Effect of Biological Silicon Fertilizer on Albic Rice Soil

Abstract

The field tested results showed the suitable biological silicon fertilizer employment quantity(450kg hm-2) has the remarkable influence to the rice leaf blade chlorophyll contents ,made the chlorophyll's contents enhance 9.56%,thus delayed the paddy rice function leaf blade's photosynthesis function time.The rice leaf blade's protection enzyme(CAT,POD) was possible to maintain the high activeness after the employment biology silicon,The biological silicon fertilizer employment quantity was 450kg hm-2,rice leaf blade's CAT,the POD activeness reacheed the maximum value,The MDA contents achieved the minimum value,which means the biological silicon fertilizer promotes the membrane fat to escape the oxidation,delayed the function leaf blade the senility.After the employment biology silicon fertilizer enhanced the adult plant dry matter archery target synthesis and the accumulation,promoted the soluble sugar to the starch shift and the carbohydrate transportation,coordinated the source and the storehouse relations.
