甘蔗新品种桂糖30种植密度试验
为了解高产高糖甘蔗新品种桂糖30在广西蔗区的适宜种植密度,为其推广应用提供配套栽培技术,于2011年分别在广西4个不同类型蔗区对该品种进行了5种不同种植密度水平比较试验,结果表明,桂糖30随着种植密度从7.5万芽/hm2增加到13.5万芽/hm2,单位面积有效茎数、蔗茎产量和蔗糖含量有提高的趋势,分蘖率和茎径则有下降趋势;其中种植密度是10.5万~13.5万芽/hm2.单位面积蔗茎产量和蔗糖含量分别在103.61~109.90t/hm2和15.50~16.44t/hm2之间变化,但差异不显著。种植密度为12万芽/hm2时的单位面积蔗茎产量和蔗糖含量最高,分别达到109.90、16.44t/hm...

| Summary: | 为了解高产高糖甘蔗新品种桂糖30在广西蔗区的适宜种植密度,为其推广应用提供配套栽培技术,于2011年分别在广西4个不同类型蔗区对该品种进行了5种不同种植密度水平比较试验,结果表明,桂糖30随着种植密度从7.5万芽/hm2增加到13.5万芽/hm2,单位面积有效茎数、蔗茎产量和蔗糖含量有提高的趋势,分蘖率和茎径则有下降趋势;其中种植密度是10.5万~13.5万芽/hm2.单位面积蔗茎产量和蔗糖含量分别在103.61~109.90t/hm2和15.50~16.44t/hm2之间变化,但差异不显著。种植密度为12万芽/hm2时的单位面积蔗茎产量和蔗糖含量最高,分别达到109.90、16.44t/hm2。桂糖30在广西的适宜种植密度是10.5万~13.5万芽/hm2.最适种植密度为12万芽/hm2,但不同类型蔗区桂糖30对不同种植密度的反应存在差异,在实际生产中要因地制宜。 |

Five different planting density levels of GT 30 planted were conducted in 4 different sugarcane plantation regions in 2011. The results were showed that millable canes, can and sugar yield was increase by planting densities were from 75 000 to 135 000 buds/hm2, but tillering rate and stem diameter were decrease.
