沙围田甘蔗“三高”施肥模式优化研究

Optimum fertilization for high yield, high sucrose content and high profit of sugarcane (Saccharum officinarum) in sandy soil

采用二次正交旋转组合设计,在珠江华侨农场的沙围田进行施肥优化试验。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,并对有关问题进行了讨论。同时,通过表证试验,说明了"三高"施肥优化方案的重演性和稳定性较强。

Using quadratic orthogonal rotating design, the optimum fertilizing experiment of sugarcane was conducted on sandy soil at Zhujiang Overseas Chinese Farm, Guangdong Province. The optimized fertilizing model was decided by means of the process of establishing mathematic model, simulating, and optimizing. Other results were also discussed. On the other hand, the replay and stability of 'threehigh' optimized fertilizing model were relatively strong in the validating experiment.
