不同栽培方式对水稻生育特性及产量的影响

Effects of Planting on Growth and Yield of Rice

  • 摘要: 采用小区对比试验方法,研究不同栽培方式对水稻生长发育及产量的影响。研究结果表明:采用宽窄行组穴均错栽培方式水稻栽培密度为27万穴·183;hm-2,大幅提高了水稻种植密度,改善了稻株光养供给条件,延长了功能叶寿命,提高了各生育时期最适叶面积指数,叶绿素含量较高,光能利用率提高,有效增加单位面积总苗数、有效穗数和实粒数,可获得11 192.75 kg·hm-2的产量,比宽窄行、宽行窄株2种栽培方式分别增产5.75%和15.03%,能发挥增产潜力,获得高产。

     

    Abstract: Effects of various planting methods on the growth and yield of rice were studied in a comparison experiment on small lots. It was found that the rice cultivation using the widenarrow rows with evenly staggered planting populations and beds, which resulted in a high planting density of 270 000 plants·hm-2, substantially enhanced the grain development, lifespan of functional leaves, leaf area index, growth period, photosynthesis, chlorophyll content, output coefficient of light energy, as well as panicle and grain counts on the rice with a yield of 11 711.11 kg·hm-2, which was 5.75% increase over the widenarrow rows, or 15.03% over the wide rows and narrow beds.
