寒地水稻侧深施肥技术研究

Study on Side Deep Fertilizing of Rice in Cold Area

试验研究了侧深施肥技术对水稻茎蘖动态及产量的影响。结果表明,侧深施肥对水稻分蘖影响不明显,侧深施肥对水稻有一定的增产作用,三大肥测深施肥比常规施肥增产96 kg/hm2,奥宝肥侧深施肥较常规施肥增产126 kg/hm2。

The effect of side deep fertilizing on tillering dynamics and yield were researched and the result indicated that side deep fertilizing had no significant effect on tillering, it had some effect on increasing production, side deep fertilizing on N, P, K can increase production 96 kg/hm^2 than general chemical fertilizer, and side deep fertilizing on Aobao can increase production 126 kg/hm^2 than general chemical fertilizer.
