甘蔗健康种苗田间栽培主要农艺性状比较

Agronomic Characters of Virus-free Sugarcane Seedlings

对甘蔗健康种苗3季新植、3季宿根的农艺性状、产量和蔗糖分含量进行了田间比较试验,结果表明:种植脱毒健康种苗可以使甘蔗单位面积产量提高23.0%～40.2%,蔗糖分含量提高0.51%～1.01%绝对值。初步认为,分蘖率高、宿根发株率高、成茎率高是甘蔗健康种苗增产的主要因素。

The virus-free sugarcane seedlings were planted 3 times to compare their agronomic characters,output and sucrose content in first and ratoon crops.The results indicated that the virus-free sugarcane seedlings increased their yield by 23.0%-40.2% and their sucrose content by 0.51-1.01 percentage point.It is believed that the improvement in cane yield of the virus-free sugarcane seedlings is attributed to better performance of the seedlings in tillering rate,ratooning power and available stalks.
