在旱坡地探索不同甘蔗新品种在不同种植密度下甘蔗农艺性状、工艺品质等方面的表现,为不同甘蔗品种在当地蔗区的合理密植提供依据。选用甘蔗新品种粤糖60,柳城05-136和福农39作为试验材料。每个品种设90000、120000、150000和180000芽/hm2四个不同的种植密度。结果表明:出苗率随种植密度的增大呈先上升后下降的趋势;有效茎数、蔗茎产量随着种植密度的增大而增加;分蘖率、成茎率、茎径随着种植密度的增大而下降。在不同种植密度方面,90000芽/hm2种植密度的甘蔗分蘖率、成茎率、茎径最大;120000芽/hm2种植密度的甘蔗出苗率最大、生长速度最快;180000芽/hm2种植密度甘蔗的产量最高;不同品种方面,粤糖60产量最高、柳城05-136的生长速最快、蔗糖分最高;福农39的还原糖分最高。柳城05-136的最佳种植密度为180000芽/hm2、粤糖60及福农39的最佳种植密度都为120000芽/hm2。
在旱坡地探索不同甘蔗新品種在不同種植密度下甘蔗農藝性狀、工藝品質等方麵的錶現,為不同甘蔗品種在噹地蔗區的閤理密植提供依據。選用甘蔗新品種粵糖60,柳城05-136和福農39作為試驗材料。每箇品種設90000、120000、150000和180000芽/hm2四箇不同的種植密度。結果錶明:齣苗率隨種植密度的增大呈先上升後下降的趨勢;有效莖數、蔗莖產量隨著種植密度的增大而增加;分蘗率、成莖率、莖徑隨著種植密度的增大而下降。在不同種植密度方麵,90000芽/hm2種植密度的甘蔗分蘗率、成莖率、莖徑最大;120000芽/hm2種植密度的甘蔗齣苗率最大、生長速度最快;180000芽/hm2種植密度甘蔗的產量最高;不同品種方麵,粵糖60產量最高、柳城05-136的生長速最快、蔗糖分最高;福農39的還原糖分最高。柳城05-136的最佳種植密度為180000芽/hm2、粵糖60及福農39的最佳種植密度都為120000芽/hm2。

Experiment of new sugarcane varieties under different density in arid hill-side fields was undertaken to explore the expression of agronomic characters and process quality for Liucheng05-136 (LC05-136), Funong39 (FN39), Yuetang60 (YT60), and to provide a reasonable density basis for local sugarcane planting. LC05-136, FN39 and YT60 were tested by using split-plot design under 4 different planting densities: 90000, 120000, 150000 and 180000 buds/ha. Germination rate showed the trend of first increasing and then decreasing with the increasing of planting density; Effective stems and cane yield represented an upward trend with the increase of planting density, white tiller rate, stem rate and stalk diameter exhibited a downward trend. Stem rate and stalk diameter were highest under the planting density of 90000 buds/ha, germination rate and growth rate were both highest under 120000 buds/ha and the highest of cane yield was achieved under 180000 buds/ha. LC05-136 got the highest growth rate and sucrose content, YT60 got the highest yield, and FN39 got the highest sugar. The optimum planting density of LC05-136 was under 180000 buds/ha, and both of YT60 and FN39 were under 120000 buds/ha.
