摘要

以N两优1998和中籼优质杂交稻万象优华占为材料,研究水稻机插秧同步侧深施肥技术对水稻产量和肥料利用效率的影响。结果表明,机插秧同步侧深施肥能够提高水稻茎蘖数,增加产量,提高肥料利用率,以机插秧在减基蘖肥20%内配合侧深施肥的处理效果较好。与风送方式相比,螺旋式侧深施肥效果更好。

Abstract

In order to improve rice fertilizer utilization and reduce pollution, a field test was conducted to study the effects of fertilizer application rate of synchronized side-deep fertilization technology on yield and fertilizer use efficiency of machine-transplanted rice, using N Liangyou 1998 and Wanxiangyouhuazhan as materials. The results showed that the synchronized side-deep fertilization technology could increase the number of tillers, grain yield and fertilizer use efficiency. The combination treatment with reduce 20% of tillering fertilizer and synchronized side-deep fertilization technology was the best. Compared with the wind feeding method, the screw side deep fertilization method has better effect.
