不同结构甘蔗群体生理动态变化及产量差异

摘要/Abstract

摘要： 为进一步探讨甘蔗栽培的高糖高产理论，试验以新台糖22号为材料，研究甘蔗种植行距为1.0m（处理A）、窄行宽株，行距为1.25m（处理B）、宽行窄株，行距1.5m（处理D）、宽窄行宽株，行距2.0m（处理C）、宽窄行窄株四种种植结构及其群体生理生化动态变化及甘蔗产量之间的差异。试验结果表明：叶绿素含量、净光合速率、蒸腾速率等生理生化指标，在各处理的表现均是分蘖期较高，伸长期最高，工艺成熟期低，但各处理之间差异不显著；每666.7m2蔗茎产量最高是处理D，为9170kg/666.7m2，最低是处理C，为7427kg/666.7m2，处理D与处理C之间差异达5%显著水平；蔗糖分最高是处理B，为15.5%，最低是处理D，为15.2%。

Abstract: In order to research high yield and sugar of sugarcane deep, T22 as the material, the four planting structures( treatment A: narrow row and wide individual ,row spacing ,1.0m ; treatment B: wide row and narrow individual ,row spacing,1.25m; treatment D: wide and narrow row–wide individual, row spacing ,1.5m; treatment C: wide and narrow row-narrow individual ,row spacing 2.0m .) and the four structure colonies’ growing trends, the physiological characters, the yield and quality were studied in the research ,the results were as follows:chlorophyll content, net photosynthesis rate, transpiration rate, etc, the results of all treatments had the same characters: high in the tiller period, the highest in elongating period, low in technical period, but the difference between them was not obvious. the highest yield of stems per 666.7m2 was treatment D, 9170kg. The lowest was treatment C, 7427kg. The difference between treatment C and D was obviously different, reaching to 5%. The highest content of sugar was treatment B, 15.5%; the lowest was treatment D, 15.2%.
