摘　　要：试验结果表明:播种量为450000芽/hm2的果蔗基本苗数偏多,株高、茎径和单株重与对照相当,有效茎数充足,故其甘蔗产量最高,比对照增产41.68%,达极显著水平,其商品性状、工艺性状、抗虫性、抗病性及抗倒性等与对照相当,是本试验中效果最佳的播种量;播种量为360000芽/hm2的果蔗基本苗数充足,株高、茎径、单株重与对照相当,有效茎达到了生产上要求的株数,故其甘蔗产量较高,比对照增产29.21%,达显著水平,其商品性状、工艺性状、抗虫性、抗病性和抗倒性均与对照相当,是本试验中效果较好的播种量;播种量为270000芽/hm2的果蔗基本苗数较足,株高与对照相当,茎径稍大,单株重最重,有效茎达到了生产上要求株数的下限,故其甘蔗产量较高,增产26.49%,达显著水平,其商品性状、工艺性状、抗虫性、抗病性和抗倒性等与对照相当,是本试验中效果次于前2者的播种量。The result of the experiment showed that total young seedlings was plenty when seed quantity was 450000 buds/hm2. Plant height, diameter and single-plant weight were equivalent to that of the check variety. The number of millable stalk was very sufficient, therefore the yield was the highest, 41.68% higher than that of the check, reaching a very significant level. It was the best treatment of the experiment in economical, technological performance and resistance to insect, disease and lodging, etc., which w...
