摘　　要：根据田间测定和有关生理分析的结果，探讨了福蔗8710在3种不同密度群体[6．3万苗/hm2（D1）、7．2万苗/hm2（D2）、81万苗／hm2（D3）]下的几个光合特性及产量、品质的差异。结果表明：福蔗8710不同密度对其群体光合性状、茎蘖消长及产量均有不同程度的影响，而对其品质性状没有显著影响；在本试验条件下适宜的种植密度为7.2万苗hm2；福蔗8710的分蘖力和群体自动调节能力均比对照种闽糖70一611强，属于中大茎、丰产高糖的中晚熟品种，栽培上应采取相应措施。The difference of several photosynthetic characters, yields and qualities of Fuzhe 8710 was inquired into in three colony densities including 63000/hm2(D1), 72000/hm2(D2) and 81000/hm2(D3) based on field trials and physiological analyses The results showed as follows.The different densities of Fuzhe 8710 affected its colony photosynthetic characters, stalk (tiller)numbers and yields in different degrees, but quality characters- The suitable density of Fuzhe 8710 was 63000/hm2 under this experiment condition. The capacities of tillering and colony selfreulation of Fuzhe 8710 were much stronger than those of M. T. 70-611, it was of the cultivars of middle big stems, high yields, high sugar contents and middle-late maturing, so the appropriate cultural practices must be adopted in production.
