Abstract
In order to know the fertilizer efficiency of sulphate-potassium magnesium in rice,the effects of different applying amount(5 treatments)and period(4 treatments)of sulphate-potassium magnesium on growth,grain yield,and quality of rice were studied using the method of field experiment.The results showed that:the grain yield,crude proteincontent,crude starch content,reduction-type vitamin C content of rice with 1 023.34 kg/ha of sulphate-potassium magnesium application was higher than the other four treatments.The grain yield,crude starch content,reduction-type vitamin C content of rice with all base application of sulphate-potassium magnesium was the maximal.The crude protein content of rice with 50% of base application,20% of applying at the jointing stage,30% of applying at the heading stage was the maximal.The optimal amount of sulphate-potassium magnesium for rice grain yield increasing and quality improving was 1 023.34 kg/ha,and the optimal method of sulphate-potassium magnesium application was at the all base application.The treatment of sulphate-potassium magnesium application with 50% of base applying,20% of applying at the jointing stage 30% of applying at the heading stage,could also significantly improve the rice quality.
