以泡桐配方施肥为研究对象,在测定林地土壤理化性质、生物量的基础上,分析了影响泡桐生长的各种因素,并对这些因素进行了综合的分析处理,采用先进数据库技术、网络技术、计算机计术,结合B/S+C/S相结合的三层WebGIS结构,模拟土肥专家计算施肥的思维方式、方法对系统进行了初步的设计。系统可为用户提供泡桐的栽培模式、配方施肥方法以及产量、质量、效益的合理指标,确保配方施肥方案科学、合理,进一步提高泡桐林木施肥的经济效益。
Taking the paulownia formula fertilization as the research object, on the basis of measuring the physicochemical properties and biomass of the soil in the forestland, various factors affecting the growth of the paulownia were analyzed. The factors were analyzed and treated comprehensively. The advanced database technology, network technology, Computer technique, combined with B / S + C / S three-layer WebGIS structure, simulation soil fertilization experts thinking way of thinking, the method of the system was initially designed. The system can provide users with the cultivation mode of paulownia, the method of formula fertilization and the reasonable indexes of yield, quality and benefit, and ensure that the formula fertilization scheme is scientific and reasonable and further improve the economic benefits of paulownia tree fertilization.
