“免烧保湿”法对旱坡地宿根蔗的增产效果及其原因分析

Analysis of the Effect and Cause of Production Increase of Perennial—root Sugarcane Planted With the Method of “Burning—free and Humidity—keeping” on Dry Slopes

本文根据海南当前旱坡地宿根蔗发芽少和成苗率低等问题,笔者从1989年开始进行“免烧保湿”处理旱坡地宿根蔗的试验。其结果表明:“免烧保湿”法对旱坡地宿根蔗的发芽、成苗和生长都有很好的促进作用,对夺取旱坡地宿根蔗高产有较大的实用价值。

Based on awareness of the low germination percentage and sprout-survival rate of perennial- root sugercane,the authors have carride out the test of treating perennial-root sugarcane grown on dry slopes with the method of “burning-free and humidity-keeping” The results of the experi- ment show that this method can greathy promote the sprouting,sprouting-survival,and the growth of the perennial-root sugarcane grown on the dry slopes.It can be of great practical value for a high- er yield.
