摘要
以紫米稻品种‘粮田紫1号’为材料,研究了不同种植密度对紫米稻产量形成特性的影响。结果表明,粮田紫1号全生育期较长,达146 d,生物产量达10 t/hm^2以上,但经济产量仅3 t/hm^2左右;种植密度对紫米稻有效穗数、每穗粒数、结实率与产量均有较大影响,本试验中株行距20.0 cm×20.0 cm处理产量最高,可达3.63 t/hm^2。粮田紫1号高产栽培关键技术措施有待进一步研究与完善。
'Liangtianzi No.1' was used as material to study the influence of transplanting density on the yield formation characteristics of purple rice.The results showed that the whole duration of 'Liangtianzi No.1' was 146 d.Its biomass yield was above 10 t/hm^2,while its economic yield was only about 3 t/hm^2.Transplanting density had a large impact on number of effective panicles,grains per spike,seed setting rate and yield of purple rice variety.In this experiment,planting spacing of 20.0 cm×20.0 cm gained the highest yield,3.63 t/hm^2.Key techniques for high-yielding cultivation of'Liangtianzi No.1'remain to further research.
