甘蔗不同密度群体的几个光合性状及产量的比较研究

Comparisons of Some Photosynthetic Characters and Yields in Various Colony Densities of Sugarcane

摘要: 比较了3个品种在不同密度群体下的几个光合性状及产量的差异。结果表明,主要生长期的群体光合面积、叶绿素总量和干物质重均与密度呈显著正相关,也与最终产量呈显著正相关。品种福蔗8710在每亩3500和4000段双芽苗下的群体光合性状及产量均明显优于其它处理。福蔗8710和福蔗8715的分蘖力与群体自动调节能力均比闽糖70-611强,栽培上应采取相应的措施。

Abstract: This paper compared the difference of some photosynthetic characters and yields in various colony densities of 3 sugarcane cultivars.The results revealed that the mass photosynthetic area,chlorophyll content and dry weight sbowed a significantly positive correlation with colony density and yield.The mass photosynthetic characters and yields of 2-bud seedlings of Fuzhe 8710 at the densities of 3500 and 4000 seedlings/Mu were significantly higher than those of other treatments.The capacities of tillering and population self-regulation of Fuzhe 8710 and Fuzhe 8715 was much stronger than that of M.T.70-611,the appropriate cultural practices are recommended in commercial production.
