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。
Based on the field measurements and the results of physiological analysis, the effects of Fucai 8710 in three different density populations [63,000 / hm2 (D1), 82,000 / hm2 (D2) and 810,000 / hm2 D3)] under several photosynthetic characteristics and yield, quality differences. The results showed that the different densities of Fuzhu 8710 had different effects on the photosynthetic characteristics, tillering growth and yield of the population, but had no significant effect on the quality traits. The optimum planting density was 72,000 hm2 under the conditions of this experiment. The ability of sugarcane 8710 to regulate tillering ability and population self-regulation was higher than that of the control cultivar 70-1611. It belongs to middle and late stem varieties with large stems and high yield and high sugar content. Corresponding measures should be taken in cultivation.
