Abstract

Abstract:

In order to solve the problem of excessive chemical fertilizer application and improper application method in rice production, provide theoretical support for reducing dosage and increasing efficiency of rice chemical fertilizers, effects of different fertilization treatments on rice yield, nutrient uptake and soil physicochemical properties were compared by comparing the effects of different fertilization treatments, and the implementation effect of different chemical fertilizer reduction measures was discussed. Compared with CF treatment, the yield of rice under FF and OF treatments were significantly increased by 7.0% and 8.6%, respectively, but the yield increase effect of BF treatment was not significant. Compared with CF treatment, the effective panicle number of rice treated with OF treatment was significantly increased by 11.3%. There were no significant differences in grain number per panicle and 1 000-grain weight among different fertilization treatments. Compared with CF treatment, the nitrogen uptake in the shoots of OF and BF treatments increased significantly by 15.3% and 15.9%, respectively. Compared with CF treatment, the partial productivity of nitrogen fertilizer in FF, OF and BF treatments were significantly increased by 15.9%, 17.7% and 14.0%, respectively. Compared with CF treatment, the phosphorus uptake in the shoots of BF treatment was significantly increased by 10.7%, while there was no significant difference between FF treatment and CF treatment. Compared with CF treatment, the partial productivity of phosphate fertilizer in FF and BF treatments were significantly increased by 78.3% and 76.4%. Compared with CF treatment, chemical fertilizer reduction treatment could maintain soil total nitrogen content. Compared with CF treatment, the soil organic matter content of OF and BF treatments was significantly increased by 7.8% and 9.3%, respectively. Considering the rice yield, nutrient uptake and soil fertility, under the conditions of 7.7% reduction in nitrogen, no phosphorus application and 42.9% reduction in potassium, the OF treatment increased the content of soil organic matter, promoted the uptake and accumulation of nitrogen in the shoots of rice, and increased the number of effective panicles of rice, which could increase the yield of rice and improve the partial productivity of fertilizer, so it was the best fertilization measure to reduce the amount of chemical fertilizer and increase the efficiency of chemical fertilizer.

Key words: fertilizer reduction, soil nutrients, rice yield, nutrient uptake
