| 摘 要： | 在大田生产条件下,研究0.8m、1.0m、1.2m、1.4m种植行距对甘蔗新良种园林17号的生长效应,以期为该品种的应用推广提供参考。结果表明:园林17号在四种种植行距下均表现出较优的生长效应,蔗茎产量达到6.8 t~8.5t/667㎡、亩含糖量达到0.9 t~1.1 t/667㎡。蔗茎产量和亩含糖量的高低排序均为1.0m行距0.8m行距1.2m行距1.4m行距,但差异不显著。生长效应模糊综合评判结果,1.0m行距最优,其次为0.8m和1.2m行距,表现最差的是1.4m行距。在传统人工作业条件下,采用1.0m行距较易获得高产高糖,其次为0.8m行距和1.2m行距;采用1.2m行距有利于节本增效。1.2m、1.4m行距适宜机械化作业,但应适当增大下种量和提高成茎率,以增加有效茎数提高产量。

| Abstract: | Under field conditions of production, research 0.8m, 1.0m, 1.2m, 1.4m growth effect of new varieties of sugarcane planting spacing garden on the 17th of expected to provide a reference for the application and popularization of varieties. The results showed that：17 garden planting spacing in four exhibited optimum growth effect .Cane production reached 6.8 t~8.5t/667 square meters, acres of sugar amounted to 0.9 t~1.1 t/667 m. Sort acres of high and low cane yield and sugar content are 1.0m spacing＆gt;0.8m spacing＆gt;1.2m spacing＆gt;1.4m spacing. But the difference was not significant Growth effect fuzzy comprehensive evaluation results, 1.0m spacing best, followed by 0.8m and 1.2m spacing, the worst performance is 1.4m spacing. In the traditional manual operating conditions, the use of 1.0m spacing easier to obtain high yield and sugar, followed by 1.2m to 0.8m spacing and line spacing;using 1.2m spacing conducive to efficiency of the section. 1.2m, 1.4m spacing suitable for mechanized operations, but the amount should be increased and improved planting into stem rate in order to increase the effective number of stems to increase production. |
