近年来,随着种植业结构的调整,我省山地甘蔗的面积已占植蔗总面积的80%左右,因此,山坡地甘蔗产量的高低,对全省蔗糖业的发展举足轻重.山坡地的主要弱点是干旱与瘠薄,加之我省主产蔗区的气候特点是冬、春、初夏连旱.这就使我省山坡地甘蔗的单产低而不稳,一般亩产仅3吨左右,若遇特殊干旱年份,亩产仅为1～2吨,还有相当面积甚至没有收成. In recent years, with the adjustment of planting structure, the area of ​​mountainous sugarcane in our province accounts for about 80% of the total area of ​​sugarcane, so the production of sugarcane on the hillside is very important for the development of the whole province’s sugarcane industry. The weakness is the arid and infertile, combined with the climate characteristics of the main producing sugarcane in our province is the winter, spring and early summer drought .This makes our province hillside cane yield is low and unstable, generally only about 3 tons per mu, Special drought years, only 1 to 2 tons per mu, there is a considerable area or no harvest.
