甘蔗的株高、茎径和有效茎数是构成蔗茎产量的重要因素,直接关系着产量的高低。但各个性状与蔗茎产量的关系密切程度不一,它们之间又互相关联、相互制约,随栽培环境条件的不同,影响蔗茎产量的主导因素也不同。根据我省的具体情况,在我省多数蔗区,争取较多的有效茎数,是夺取高产的基础;争取甘蔗早拔节、早伸长,充分利用大伸长期的水、热、光、肥等条件迅速伸长,增加蔗株高度,是夺取甘蔗高产的又一重要条件;至于茎径与产量的关系则不是
Sugarcane plant height, stem diameter and number of stems is an important factor in the production of sugarcane stems directly related to the level of output. However, the relationship between the traits and the yield of cane is close, and they are interrelated and mutually restricted. With the different cultivation environmental conditions, the dominant factors affecting the yield of cane are also different. According to the specific conditions of our province, striving for more effective stalks in most sugarcane planting areas in our province is the basis for seizing high yield; striving for early planting and early elongation of sugarcane, making full use of water, heat, light and fertilizer Other conditions such as rapid elongation, increase the height of sugarcane plants, is to capture another high yield of sugar cane is an important condition; as for the relationship between stem diameter and yield is not
