我们自1988年推广宿根蔗种植已有10年的时间了,但宿根蔗缺苗断垄的问题始终未能从根本上解决,而一般情况缺苗断垄达15％,严重的超过20％。近两年我们通过试验示范总结出了“甘蔗催芽优选扦插补种”新技术,1997年进行了大面积推广。实践证明:运用此方法,补种目标明确、补种后出苗率高(90％以上)、补种苗与大田宿根苗生长基本同步,效果好。若按宿根对象田每 We have been promoting the cultivation of ratoon cane for about 10 years since 1988, but the problem of raking cotton seedlings has never been solved fundamentally. In general, the shortage of ragweed is up to 15% and seriously to over 20%. In the past two years, we summed up the experiment and demonstration of “sugarcane germination preferred replanting” new technology, large-scale promotion in 1997. Practice has proved that: using this method, the goal of replanting is clear, the rate of emergence after replanting is high (more than 90%), and the effect of supplementary replanting and rooting seedlings of Daejeon is basically synchronous. If the root object by the Tian per
