提高甘蔗群体光合效率的栽培措施

Cultural measures for increasing the photosynthetic efficiency of sugarcane population

文章从甘蔗良种选用、种植密度、蔗地覆盖、肥料施用、田间管理等方面对提高甘蔗群体光合效率进行了概述。认为必须充分利用甘蔗基因多样性,并加以遗传改良;采用先进的栽培措施,创造良好的栽培条件,改善甘蔗群体结构,提高群体透光率、叶面积指数、光合强度及光能利用率等,从而提高甘蔗群体光合效率和产量。

The paper summarized the improvement of photosynthetic efficiency of sugarcane population from selection of superior seed cane, planting density, cane field covering, fertilizer applying, field management etc. It suggested that it must fully use genotype diversity of the crop and make genetic improvement, adopt advanced cultural measures and create good cultural conditions to increase the photic rate, leaf area index, photosynthetic intensity and efficiency for solor energy utilization etc, so that to increase the photosynthetic efficiency and yield of sugarcane population.
