摘要
采用二次正交旋转组合设计,在广东四会市大旺管理区的冲积土水田蔗区进行施肥优化试验,通过建立数学模型、模拟和寻优,初步建立了三高施肥优化方案;同时,根据模型参数、单项性状指标的施肥方案和综合性状指标的优化施肥方案,对肥料三要素及其施用水平对蔗茎产量、蔗汁锤度和净产值的影响进行了比较分析。
Using quadratic orthogonal rotating design, the optimum fertilizing experiment of sugarcane was conducted on paddy soil (alluvial soil) at Dawang District, Xihui, Guangdong Province. The optimized fertilizing model was decided by means of the process of establishing regression model,simulating,and optimizing.On the other hand,the comparison and analysis of fertilizing effects on cane yield, Brix in juice and net income were conducted based on the parameters of mathematics models,the fertilizing schemes for single character and comprehensive fertilizing schemes.
