Abstract

Abstract: Side deep fertilization technology on rice is a precise and quantitative fertilizer application technology. In order to explore the effect of side deep fertilization technology on the potential of nitrogen fertilizer reduction and yield of rice, four treatments were set upA blank control treatment of nitrogen fertilizer, an artificial throwing fertilization treatment, simultaneous side deep fertilization and side deep fertilizati-on to lose weight. The results showed that under the same amount of fertilization, the output of side deep fertilization treatment in Xiaochang and Gongan were 8.08 t/hm² and 7.57 t/hm², respectively, which increased the yield by 7.30% and 1.61% compared with the artificial throwing fertilization treatment; The yield of side deep fertilization and 20% weight loss treatment was equivalent to that of artificial throwing fertilizer treatment; Compared with artificial throwing fertilizer treatment（T1）, side deed fertilization（T2） increased the income by 3 115.0 yuan//hm² and 1 911.0 yuan//hm² in Xiaochang and Gongan test sides. It can be seen that side deep fertilization technology plays an important role in reducing the application of nitrogen fertilizer and increasing rice yield and efficiency.

Key words: rice, side deep fertilization technology, reduced nitrogen application, yield, cost-benefit
