不同种植方式对水稻产量的影响

Effects of Different Cultivation Methods on Yield of Rice

为积极应对干旱天气对黔西南州水稻生产的影响,探索新型轻简、增产、增效的水稻种植模式,进行了免耕直播覆膜、覆膜移栽、常规等行距移栽3种不同种植方式试验。结果表明:免耕直播覆膜和覆膜移栽有效穗、结实率和产量均高于常规等行距栽培,3种栽培方式有效穗分别为19.7万/667m2、18.6万/667m2、17.1万/667m2,结实率分别为89.3%、84.1%、79.4%,产量分别为663.4kg/667m2、671.2kg/667m2、587.5kg/667m2。

For resolve the problem of drought to occur in summer in Qianxinan,to explore the new simplified,yield-increasing,benefits-increasing cultivation mode,3different cultivation methods,no-tillage direct seeded rice with plastic film mulching,transplanted rice with plastic film mulching and conventional cultivation were tested.The results showed that effective spiked,setting percentage and yield of no-tillage direct seeded rice with plastic film mulching and transplanted rice with plastic film mulching were higher than conventional cultivation,the effective spiked,setting percentage and yield of no-tillage direct seeded rice with plastic film mulching,transplanted rice with plastic film mulching and conventional cultivation were 197000/667m^2、186000/667m^2、171000/667m^2,89.3%、84.1%、79.4%,663.4kg/667m^2、671.2kg/667m^2、587.5kg/667m^2,respectively.
