果（甘）蔗生长期长，从4月初排种到11月初收获，历时200多天，苗期阶段（约90天左右），生长慢，土地利用率和光能利用率都比较低。此期著选择与果蔗互利共生的作物进行间套种，则能产生良好的互补效应，提高蔗地的利用率和经济效益根据本课题绷993年调查，蔗地间套种的一般增 The fruit (sweet) sugar cane grows for a long time and it is harvested from early April to early November. It lasts for more than 200 days. During the seedling stage (about 90 days), it grows slowly, and both land utilization and light energy utilization rate are relatively low. In this period, the intercropping of crops with symbiotic symbiosis with sugar cane can produce good complementary effects and improve the utilization and economic benefits of sugarcane fields. According to the investigation of 993 years of this project, the general increase of interplanting between sugarcane fields
