广东省的自然资源条件很适合甘蔗生产。但旱地蔗区的旱、瘦、浅是低产的主要原因。在过去的十几年中 ,通过对旱地甘蔗“三高”栽培技术的应用试验研究 ,把单项技术进行组合配套和改进提高 ,并通过大型的推广项目进行推广 ,取得了增产增收的效果 ,社会经济效益显著。主要技术措施 :一是选用适合旱地蔗区的高产高糖、抗逆性强的优良品种 ;二是把常规栽培改为地膜蔗技术 ;三是改进施肥方法 ,实行配方施肥 ;四是改进耕作方式 ,推广防旱保水技术 ;五是推广秋冬植蔗 ,延长甘蔗生长期 ;六是改宿根蔗迟管为宿根蔗早管 ;七是及时防治病虫鼠草害 ,确保增产增收 Natural resources in Guangdong Province are suitable for sugarcane production. However, the dry, thin and shallow dryland sugarcane area is the main reason for low yield. In the past ten years, through the experimental research on the “three highs” cultivation techniques of sugarcane in dry land, the single technology has been combined and improved and improved, and has been promoted through large-scale promotion projects, and has achieved the effect of increasing output and increasing income. Significant economic benefits. The main technical measures are as follows: one is to select good varieties with high yield and high sugar and strong resistance to drought in sugarcane field; the second is to change conventional cultivation to plastic film cane; the third is to improve fertilization method and implement formula fertilization; the fourth is to improve farming methods , Promotion of drought and water conservation technology; five is to promote autumn and winter plant cane, to extend the growth period of sugar cane;
