摘要
针对原始强化栽培体系本土化技术方案由于种植密度过小造成减产等不足进行改良,以优质常规稻品种力源占1号为试验材料进行优质稻强化栽培种植密度试验。结果表明,种植密度为16.65万～21.45万穴/hm2均能极大发挥植株个体的生长潜力,获得显著的增产效果,为优质常规稻强化栽培适宜密度;改良后的强化栽培体系方案仍存在结实率和千粒重较低等问题。
In the early season in 2006, a preliminary rice intensification system （SRI） localization technique was made and studied. It was found that low density was the main reason causing rice yield reduction. This study used Liyuanzhanl as the material to conduct a planting density experiment on high-quality rice intensification system （SRI） localization. The results showed that the growth potential of the rice plant was great and the significant effect of yield increase was obtained under the planting density of was between 166500 to 214500 holes/hm^2. However, the seed setting rate and the 1000-grain weight of all the SRI treatment decreased.
