摘　　要：水稻机插侧深施肥是一项肥料精确定量施用技术。为探讨机插侧深施肥技术对水稻氮肥减施潜力和产量的影响,设置氮肥空白对照、人工抛撒施肥、侧深施肥及侧深施肥减肥4个处理。结果表明,等量施肥情况下,侧深施肥处理在孝昌试验点和公安试验点产量分别为8.08 t/hm^(2)和7.57 t/hm^(2),分别较人工抛撒施肥处理增产7.30%和1.61%;侧深施肥减肥20%处理产量与人工抛撒施肥处理相当;机插侧深施肥(T2)较人工抛撒施肥(T1)在两个试验点分别增收了3115.0元/hm^(2)和1911.0元/hm^(2)。可见,机插侧深施肥技术在氮肥减施、水稻增产增效方面具有重要作用。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 up:A 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/hm^(2) and 7.57 t/hm^(2),respectively,which increased the yield by 7.30%and1.61%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 3115.0 yuan//hm^(2) and 1911.0 yuan//hm^(2) 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.
