In order to study the effect of carbon-based compound fertilizer(carbon-based fertilizer) on nitrogen(N), phosphorus(P) and potassium(K) absorption and yield, taking hybrid rice‘Zhuliangyou 819'as theexperimental material, we set up field experiments using randomized block design in 2014 and 2015. Theresults showed that the utilization ratio of nitrogen fertilizer, phosphate fertilizer and potassium fertilizer undercarbon-based fertilizer treatments increased by 5.6%, 4.3% and 7.6%, respectively, compared with that underordinary ferti...
