手机专家系统在早稻精准施肥上的应用初探

摘要

The study determ ined nutrientcontents ofthe soilfrom random ly chosen paddy fields before the experim ent.Itused “m obile phone expertsystem on soilcontents testand precise fertilization forH unan m ajorcrops” to recom m end fertilization solution,com pared the im pacts of different fertilization form ula on the yield, agricultural characteristic of early rice, analyzed the econom ic benefits, and conducted the form ula verification.The results show ed thatthe recom m endation offertilization from the system w as ofhigh precision and w e could obtain m ore reasonable fertilization solution by using this system . This research m ay provide us w ith scientific basis for the precise fertilization ofearly rice in large areas.%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。
