摘　　要：为探究机插秧侧深施肥技术对水稻生长发育及产量等构成因素的影响,试验设基肥人工撒施为对照组,基肥侧深施肥、基肥减施10%侧深施肥、基肥减施20%侧深施肥三个处理,进行对比试验研究。结果表明:在基肥量相同的前提下与人工撒施相比,侧深施肥处理更有利于促进水稻分蘖,提高了成粒数、千粒重以及产量,其中千粒重和产量的增幅分别为8.6%和4.3%。In order to explore the effects of side deep fertilization technology on rice growth, development and yield, a comparative experimental study was conducted in three treatments: deep fertilization on the base side, 10% reduction on the base fertilizer and 20% reduction on the base fertilizer. The results showed that under the same base fertilizer amount,the side-deep fertilization was more beneficial to promote rice tiller, and increased grain number, 1000-grain weight and yield, with the increase of 1000-grain weight and yield by 8.6% and 4.3%, respectively.
