采用广西推广面积最大的桂糖11号和目前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(B),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,桂糖11号A处理出苗率比B、C、D处理高270%～647%,新台糖16号A处理出苗率比B、C、D处理高343%～6112%;两个品种剥叶不砍种的分蘖率高于其他方式的种茎处理,桂糖11号C处理分蘖率比A、B、D处理高8119%～1064%,新台糖16号C处理分蘖率比A、B、D处理高213%～442%。桂糖11号不砍种的株高前期有较快的伸长速度,茎径增粗明显高于砍种处理。在甘蔗大生长后期和工艺成熟期土壤干旱严重的条件下,桂糖11号不砍种下种的甘蔗品质均明显优于砍种的,桂糖11号C处理甘蔗蔗糖份比A、B、D处理的高05%～23%(绝对值)。新台糖16号A处理蔗产量比B、C、D的高250%～330%。
Using the Guangxi Guixi 11 with the largest area for promotion and two sugar cane varieties currently being actively promoted by Xintaandu 16 as test materials, seed soaking for disinfection (A), cutting and seed soaking (B) (C), do not strip the leaves do not cut species (D) 4 kinds of species under the way. The results showed that in the early stage of soil moisture and temperature basically meet the requirements of sugarcane germination and growth conditions, the two sugarcane varieties are cut seed soaking seed germination stem emergence early emergence rate is high, Guitang No. 11 A treatment of emergence rate Which was 270% ~ 647% higher than that of treatments B, C and D. The seedling emergence rate of Xintai sugar 16 A was 343% -6112% higher than that of B, C and D. The tillering rate of the two cultivars was higher than others Compared with A, B and D treatments, the tillering rate of Cinnamon 11 C was 8119% -1064% higher than that of A, B and D treatments. Guitang 11 did not cut the pre-plant height faster elongation, stem diameter thickening was significantly higher than the cut seed treatment. In the late growth stage of sugarcane and soil arid conditions in the mature stage of the technology, the quality of sugarcane under the non-cuttings of Guiguang 11 was significantly better than that of cuttings. The sugar content of sugarcane of Guitang 11 C was higher than that of A, B, D processing of high 05% to 23% (absolute value). New Taiwan sugar 16 A processing cane yield than B, C, D of 250% to 330%.
