甘蔗之所以在世界上广为栽培并成为最重要的糖料作物之一,这与它是一个高产作物有密切关系,理论和实践都证明甘蔗具有很高的丰产性能和增产潜力。世界上单位面积产量最高的国家埃塞俄比亚和秘鲁,每公顷甘蔗产量分别为158吨和156吨。另外,据H·Rostron资料,认为现有南非甘蔗品种能获得的最高产量为每年每公顷145～160吨,甘蔗干物质含量约为25%;Bull和G1asziou从理论上估计,在12个月中,现有甘蔗品种产量的最高潜力为每
The reason why sugar cane is widely cultivated in the world and become one of the most important sugar crops is closely related to its high yield crop. Both theory and practice prove that sugarcane has very high yield and yield potential. Ethiopia and Peru, the countries with the highest yield per unit area in the world, produce 158 tons and 156 tons of sugarcane per hectare, respectively. In addition, according to H. Rostron, the highest available yield of existing South African sugarcane varieties is 145 to 160 tons per hectare per year and the dry matter content of sugarcane is about 25%. Bull and G1asziou theoretically estimated that in 12 months , The highest potential for the production of existing sugarcane varieties is per
