以广西区种植面积最大的‘新台糖22’、‘桂春2号’、‘柳豆3号’和‘桂春8号’为间作套种试验材料,研究探索不同大豆品种、不同播期及不同间种密度对甘蔗产量、品质及综合经济效益的影响。试验结果表明,在同等管理和施肥条件、种地养地、保证甘蔗品质和产量的前提下,以第2播期间种2行中熟大豆品种效果最好。综合经济效益最高的是第2播期间种2行的晚熟大豆品种。 With the largest planting area of ​​Guangxi Xintai sugar 22 ’,’ Gui-chun 2 ’,’ Liu bean 3 ’and’ Gui-chun 8 ’Intercropping intercropping test materials to explore the different soybean varieties, different sowing dates and different Effect of Seed Density on Sugar Cane Production, Quality and Comprehensive Economic Benefit. The results showed that under the conditions of the same management and fertilization, planting and raising of land, and ensuring the quality and output of sugarcane, the best effect was achieved in planting middle-aged soybean varieties with 2 rows during the second sowing date. The most comprehensive economic benefit is the late sowing of 2 lines of late maturing soybean varieties.
