“双高”甘蔗是指产量高、含糖量高的甘蔗,即“双高”甘蔗优势区(主要分布在广西、云南、广东3个省区)平均每667平方米(1亩)产量提高到5吨,含糖率则提高到14.5%。近几年,广西各地先后启动了甘蔗“双高”基地建设试点,总结出了“可复制、可推广”的栽培技术。具体技术要点如下。1.选地。甘蔗高产地块宜选择在海拔1200米以下,冬季无霜或微霜地区种植。甘蔗既不耐旱更不耐涝,应选肥力高、水肥供应丰富、供应时间长、排灌方便、土壤结构良好、黏度适中的土 Sugarcane refers to sugarcane with high yield and high sugar content, ie, 667 square meters (1) of sugarcane dominant area (mainly distributed in three provinces of Guangxi, Yunnan and Guangdong) Mu) production increased to 5 tons, sugar content increased to 14.5%. In recent years, Guangxi has started a pilot project for the construction of sugar cane “Shuang Gao ” and concluded “cultivation techniques that can be replicated and promoted”. Specific technical points are as follows. 1. Choose the place. Sugarcane high-yield plots should choose at an altitude of 1200 meters below the winter frost-free or frost areas planted. Sugarcane is neither drought nor waterlogging, should choose a high fertility, abundant water and fertilizer supply, long supply time, convenient irrigation and drainage, soil structure is good, moderate viscosity soil
