施肥技术对甘蔗产量和品质的影响

Effects of fertilization skill on yield and quality of sugarcane

在每hm2施鱼粉有机-无机复混肥1 500 kg的大田生产条件下,采用随机区组设计,设置5种施肥技术处理,研究其对甘蔗农艺性状、生理生化特性、蔗茎产量及品质等方面的生长效应。结果表明:D处理蔗茎产量和含糖量最高,D处理与A处理的蔗茎产量差异达显著水平,含糖量差异达极显著水平;D处理与B、C、E处理间的含糖量差异达显著水平;其他处理间差异不显著。

Five fertilization levels, name as treatment A,B, C,D, E, were designed with randomized block to study the agronomic characters, the physiological biochemistry characteristic, the yields of stem and the qualities of sugarcane. The results indicated that yield of stem and the sugar content of treatment D were highest, which were significantly greater than treatment A （yield P〈0.05, sugar conten P〈0.01）, B, C, E （yield P〉0.05, sugar content P〈0.05）. No significant difference of yield and sugar content was found among the treatment A, B, C, E.
