8个甘蔗品种比较试验

Comparative Test on Eight Varieties of Sugarcane

[目的]推广应用甘蔗优良品种以获得甘蔗高产、高效。[方法]在栽培条件一致的情况下,选择8个甘蔗品种在东方红农场进行比较试验,测定其农艺性状、产量、糖分、宿根性等指标。[结果]ROC22、台糖92-2668前期生长较快,后期茎长、茎重突出,产量较高,是参试品种中较优良的品种,但台糖92-2668后期虫节率高、糖分较低;ROC16糖分较高,在生产中加强水肥管理,其产量亦可显著提高,有一定的推广价值。[结论]该研究可为甘蔗良种在东方红农场的大面积推广应用提供科学依据。

[Objective] To obtain the high-yield and high-efficient sugarcane, and to popularize good sugarcane varieties. [Method] Under the same cultivation condition, comparative test of eight sugarcane varieties was carried out in Dongfanghong Farm. The agronomic characters, yield, glucose content and perennial root were researched. [Result] Varieties ROC22 and Taitang 92-2668 grew rapidly in early stage. The stem length and stem weight were prominent;yield was relatively high. Therefore, these two varieties were relatively excellent varieties among the testing samples. However, Taitang 92-2668 got a high rate of worm section rate and low glucose content. Besides, ROC16 also had high glucose content, and its yield might be significantly improved if strengthening the management of sewage sludge during the growth stage, so that ROC16 had a cer-tain popularization value in Dongfanghong Farm.
