摘要
通过对山东省主要果产区成龄国光苹果园土壤的多点调查和分析,应用多元回归分析,建立土壤营养成分含量和比例与果树产量品质关系的多元回归数学模型。模型的解析表明,增加土壤有机质是提高果树产量的关键;P/K比例是影响果实品质的主要因素;生产中必须重视微量元素锌和硼的含量。线性规划求解出丰产优质的土壤营养含量和优化配比,为果园土壤管理、合理配方施肥、提高产量、增进品质提供理论依据和指导性方案。
Soils in 'Rall' apple orchards in the main apple producing area of Shandong Province were investigated. Analysis of multi-regression was used to set up a mathematical model of multiple regression in yield and quality with nutrient content and proportion of soil. Model analysis showed that to add organic matters to soil was a key for increasing yield. P/K was the mainfactor affecting the quality of fruit. Attention should be paid toboron content of soil in production. Linear programming was appliedto optimize nutrient content and proportion of soil for high yieldand good quality. Theoretical basis and directional scheme wereprovided for soil management, rational fertilization, increasingyield and improving the quality of fruit.
