摘  要:
目的:明确"皖稻153"的栽插密度.方法:采用单因素随机区组试验设计,设置33.3 cm*25 cm、28.6 cm*25 cm、25 cm*25 cm、22.5 cm*25 cm、20 cm*25 cm、18.2 cm*25 cm共6个不同栽插密度处理,以33.3 cm*25 cm为对照,考察栽插密度对"皖稻153"茎蘖动态及产量的影响.结果:随着栽插密度的提高,每穴的茎蘖数及有效穗数均呈下降趋势;抗倒能力呈先上升后下降的趋势;穗实粒数呈逐渐下降趋势;粒重与栽插密度间的关系不明显;实际产量亦呈先提高后下降的趋势,其中,以25 cm*25 cm栽插密度的实际产量最高,达13 125 kg/hm~2,较其他栽插密度处理增产均达显著水平.结论:"皖稻153"在沿淮地区麦茬栽培栽插密度以25 cm*25 cm (1.6*10~5穴/hm~2)为宜.

摘  要:
Objective:To provide technical and theoretical reference for planting density of "Wandao153" actual production. Methods: Randomized block design was used to set up 33.3 cm×25 cm(A), 28.6 cm×25 cm(B), 25 cm×25 m(C), 22.5 cm×25 cm(D), 20 cm×25 cm(E), 18.2 cm×25 cm(F)six treatment of planting density.To investigate the effects plants density on tiller dynamics and yield of Hybrid "Wandao153".Results: The number of tillers and effective panicles per hole were dropped with the increase, the lodging resistance increased first and then decreased, the number of grains per spike decreased gradually, the relationship between grain weight and planting density was not obvious, and the yield also increased first and then decreased. Among them, the yield of 25 cm×25 cm(treatment C) was the highest.Conclusion: The planting density of "Wandao153" should be about 25 cm×25 cm(1.6×10~5 plants/hm~2).
