手机专家系统在早稻精准施肥上的应用初探

Application of Mobile Phone Expert System on Early Rice Precise Fertilization

试验前对随机选取的稻田土壤养分含量进行了测定,利用"湖南省主要农作物测土配方施肥手机专家系统"进行推荐施肥,通过对比不同配方施肥对早稻产量、农艺性状的影响及经济效益、配方验证分析,结果表明,该系统推荐施肥方案的精准性高,采用该系统能获得更合理的复合肥配方方案。研究为今后早稻大面积实施精准施肥提供依据。

The study determined nutrient contents of the soil from randomly chosen paddy fields before the experiment. It used ＂mobile phone expert system on soil contents test and precise fertilization for Hunan major crops＂ to recommend fertilization solution, compared the impacts of different fertilization formula on the yield, agricultural characteristic of early rice, analyzed the economic benefits, and conducted the formula verification. The results showed that the recommendation of fertilization from the system was of high precision and we could obtain more reasonable fertilization solution by using this system. This research may provide us with scientific basis for the precise fertilization of early rice in large areas.
