第五节栽培管理原料甘蔗栽培管理,是要从栽培技术上争取更高单位面积产蔗量和更好的原料甘蔗品质(主要是蔗糖分)。甘蔗的生长有两个明显的特点和规律。第一,产量和质量的矛盾统一。原料蔗茎既是产量的物质,又是贮存蔗糖的物质,产量和质量是统一的;但是蔗茎的伸长则要有高温、水分(营养)及光照的环境,而蔗糖的积累又要有干旱、较低温的环境,这又
Section V Cultivation and Management The raw material sugarcane cultivation and management is to strive for higher output of cane per unit area and better raw material sugarcane quality (mainly sucrose) from the cultivation techniques. Sugar cane growth has two distinct characteristics and laws. First, the contradiction between output and quality is uniformed. Raw cane stems from both yield and sucrose, yield and quality are uniform; however, cane stem elongation requires high temperature, moisture (nutrient) and light, and sucrose accumulation is accompanied by drought , A lower temperature environment, which again
