摘　　要：从高产角度出发,探讨2—5月不同播期处理对甘蔗生长与产量的影响。结果表明,2、3月播期处理的新植蔗出苗慢、苗数多;2月播期处理的新植蔗株高、茎高显著高于其他处理;新植蔗单茎重、蔗茎产量、蔗糖含量及蔗糖产量随播期推迟而下降;3月播期处理的宿根蔗茎高、单茎重、蔗茎产量及蔗糖产量高于其他处理;两季总蔗茎产量、总蔗糖产量分别为159.15~217.07、20.91~30.81 t/hm^(2),均以3月播期处理最高,其次是2月播期处理,而5月播期处理最低。可见,3月播种的总甘蔗产量、产糖量较高。The growth and yield of sugarcane was studied for high-yield cultivation, including planted in February, March, April and May. The results showed that the rate of emergence of planting cane planted in February and March was slow, but the number of seedlings was more than planted in other months. The plant height and stalk height of planting cane planted in February were significantly higher than planted in other months.The single stalk weight, cane yield, sucrose content and sucrose yield of planting cane decreased with the delay of planting date. The stalk height, single stalk weight, cane yield and sucrose yield of ratoon cane planted in March were higher than those planted in other months. The cane yield and sucrose yield in two-season was 159.15-217.07, 20.91-30.81 t/hm^(2), respectively, and that of planting in March was highest, followed by sown in February, and the lowest was in May. In conclusion, the cane yield and sucrose yield planted in March were higher.
