摘要
不同栽培方式的水稻产量差异达极显著水平,手插秧和抛秧的产量极显著地高于乳苗抛栽。乳苗抛栽的成苗率低 ,成穗率低。乳苗抛栽比手插秧和抛秧在田间的生长期大大缩短 ,各个生育时期均有所延后 ,乳苗抛栽群体的灌浆比手插秧和抛秧延迟 ,灌浆持续期比手插秧和抛秧短 ,千粒重降低。
The yield differences of four different planting patterns were very significant. The growth stage of nurseling-seedling scattering rice was delayed. The percentage of panicle bearing tillers was low; the number of panicles per unit area was not enough;the spikelet number per panicle was small. The average grain-filling rate was fast and grain-filling period was short. The grain-filling was not enough and 1000-grain weight decreased.
