已把促进分蘖作为亚热带气候区的甘蔗栽培技术措施。但分蘖茎的茎长比母茎短,茎径比母茎小,且蔗汁品质比母茎差。根据试验的数据可知,在热带气候区,由于甘蔗发芽率较高,大多数蔗株是母茎。但是在亚热带气候区则不是这样。因此,如果能用农艺技术来增加母茎数,那么便可获得甘蔗产量的突破。印度甘蔗研究所(勒克瑙)已证实,采用“环形坑种植法”可以促进母茎的生长,而抑制分蘖生长。
Sugarcane cultivation techniques that promote tillering as a subtropical climatic zone have been adopted. However, the tiller stems stem shorter than the stem, stem diameter smaller than the parent stem, and sucrose juice quality worse than the parent stem. According to the experimental data, we can see in the tropical climate zone, because of the higher germination rate of sugarcane, most of the sugarcane plants are stems. However, this is not the case in subtropical climates. Therefore, if we can use agronomic techniques to increase the number of female stems, we can get a breakthrough in sugar cane production. The Indian Sugarcane Research Institute (Lucknow) has confirmed that the use of a “pit-planting” method can promote the growth of mother stems and inhibit tillering growth.
