新植蔗比宿根蔗封行迟,约迟27.6天。因此新植蔗间套种较有利宿根蔗,但比宿根蔗更要注意防旱、防咸、防草及防止水土流失。封行期中宿根蔗的株高、茎径都比新植蔗不均匀,同时宿根蔗的最高活茎数约在5月底,而新植蔗的最高活茎数约在6月初,是由于宿根蔗的反馈现象发生较早。因此,在生产上,我们必须从低斩收获,春暖后全部把宿根蔗田高大笋斩齐(俗称“回头不见青”),及早进行
The newly planted sugarcane than the dormant sugarcane baggage late, about 27.6 days later. Therefore, the new planting sugarcane intercropping more favorable ratoon sugarcane, but more than the ratoon sugarcane should pay attention to drought, salty, grass and prevent soil erosion. The height and stem diameter of ratoon sugarcane in sealing stage were all not uniform compared with that of new planting sugarcane, while the highest surviving stalks of ratooning sugarcane were about 5 at the end of the month, while the highest number of live stalks of newly planted sugarcane was about 6 months earlier, The feedback phenomenon occurred earlier. Therefore, in production, we must harvest from a low harvest, after the spring all the ratoon cane crop tall bamboo shoot together (commonly known as “back green”), as early as possible
