江西于都蔗区每年都有三分之一的蔗田换蔸,老蔗蔸的下部茎约有5—10厘米长的短密节段,每节有一个芽,在春分至立夏前,利用老蔗蔸再植或育苗移栽,配合适当的农业措施。既可解决宿根蔗缺株断垄的补植种苗,又能完成上年留种不足的扩种计划,还能获得较高亩产。例如我县车溪乡蔗农王志达,1985年品种赣蔗1号,土质河洲潮沙田。第4年宿根(对照)亩产4.24吨,同块蔗田的老蔗蔸再植亩产7.29吨,比对照增产72%。
Each year in Jiangxi Province, there is one-third of sugar cane fields in the sugar cane area, and the lower stems of the old cane pots have 5-10 cm long short segments with a bud in each section. Before the spring equinox, Replanting old cane or seedling transplanting, with appropriate agricultural practices. The invention can not only solve the replanting planted seedlings of the dormant sugarcane in the pest-root cane but also complete the plan of expanding the seed in the previous year and still obtain higher mu production. For example, my county Chexi Township sugarcane farmers Wang Zhida, Gan cane in 1985 on the 1st variety, soil Hezhou tidal Shatian. The fourth year of perennial (control) mu 4.24 tons, with the old sugarcane cane replant acres of sugarcane production 7.29 tons, 72% increase over the control.
