摘要

摘要: 以优质稻宜优673为材料,研究了不同栽植密度与施肥量对水稻生长发育和产量的影响。结果表明:栽植密度、施肥量及其互作均对水稻产量有显著影响。增加栽植密度可显著提高有效穗数,每穗粒数略有减少,对结实率和千粒重影响不大,达到最高产量的密度为24万丛.hm-2。增加施肥量可显著增加宜优673的有效穗和穗粒数,结实率有所下降,千粒重呈上升趋势,达到最高产量的施N量为195kg.hm-2(N∶P2O5∶K2O比例为1∶0.5∶1)。在供试条件下,纯收益也随栽植密度与施肥量的提高而提高。

Abstract: Yiyou 673 was used in this study to determine the growth and yield of the rice under different planting densities and fertilizer applications.The results showed that the number of rice panicles significantly increased,and the grains per spike reduced,as the planting density increased.On the other hand,planting density had little effect on the grain-set rate or the 1000-grain weight of the rice.The optimum planting density for Yiyou 673 was determined to be 240 000 plants per hm2.When the amount of fertilizer was increased,the number of panicles and grains per spikelet were significantly improved,while the grain-set rate declined and the 1000-grain weight was on a rising trend.The optimum nitrogen fertilization for Yiyou 673 was 195 kg per hm2,and the N∶P2O5∶K2O ratio,1∶0.5∶1.Under the conditions tested,the net profit could be improved by increasing the planting density and fertilization.
