| 摘 要： | 采用广西推广面积最大的桂糖１１号和正积极推广的新台糖１６号两个甘蔗品种作试验材料，分砍种浸种消毒（Ａ），砍种不浸种（Ｖ），剥叶不砍种（Ｃ），不剥叶不砍种（Ｄ）４种下种方式。试验结果表明，在前期土壤水分及温度基本满足甘蔗萌芽与生长要求的条件下，两个甘蔗品种均以砍种浸种消毒种茎处理的出苗早、出苗率高，糖１１号Ａ处理出苗率比Ｂ、Ｃ、Ｄ处理高２７．０％￣６４．７％，新台糖１６号Ａ处理出苗率比Ｂ、Ｃ、Ｄ处理

| Abstract: | Two sugarcane
cultivars , i.e. GT11 and ROC 16 , were employed in the experiment for comparing 4 ways
for planting the seed cane ,which are the treatments of planting with sterilized twobud
seed cane (A) ,nonsterilized twobud seed cane (B) , multiplebud seed cane without sheath
(C) , and multiplebud seed cane with sheath (D).When the soil moisture and temperature
were good for the germination and growth of sugarcane, the seed cane germinated earlier,
and the emergence rate was higher in the treatment with sterilized twobud seed cane as
compared with the other treatments. For tillering rate, however, the treatment with
multiplebud seed cane without sheath were higher. For GT11, the plants from the multiple
seed cane grew faster at the early stage, and the stalk diameter was higher than those
from the twobud seed cane. At the stages of late growth and technical maturation and when
the severe soil drought occurred, the cane quality were better in the treatments with
multiplebud seed cane than those with twobud seed cane. Eventually, the cane yield was
higher slightly and sugar yield was significantly higher in the treatment with multiplebud
seed cane without sheath than those in the other treatments for GT11. For ROC 16, however,
the cane yield showed the highest in the treatment with sterilized twobud seed cane. |
