福建是我国的甘蔗高产区之一。仙游县是福建蔗区的中心,面积占全省的五分之一。平均每1ha产量98,730kg,每1ha产糖13,627.5kg,为全省之冠。本研究选择代表蔗区中上水平的玉井村为对象,收集其1971—1980年的自然资源、社会资源、种植制度、作物产量、农田养分平衡状况以及经济效益等资料,运用数理统计和线性规划进行定量分析,探讨蔗区农田生态系统的优化结构。研究对象和研究方法玉井村地处木兰溪畔。气候资源优越,年均温20.2℃,无霜期320d,≥10℃的活动积温
Fujian is one of China’s high-yield sugarcane producing areas. Xianyou County is the center of Fujian Cane District, accounting for one fifth of the province. The average yield of 98730kg per 1ha, sugar per 1ha 13,627.5kg, the highest in the province. In this study, Yushijing village, which represents the upper level of sugarcane field, was selected as the object to collect the data of natural resources, social resources, planting system, crop yield, farmland nutrient balance and economic benefits from 1971 to 1980. Using mathematical statistics and linear programming Quantitative analysis of sugarcane area farmland ecosystem optimization structure. Research objects and research methods Yujing Village is located in Mulan Creek. Climatic resources are superior, with an average annual temperature of 20.2 ℃, frost-free period of 320d, ≥ 10 ℃ activity accumulated temperature
