2种测土配方施肥专家系统在耒阳早稻上的应用比较
|
摘要
根据耒阳市试验地土壤养分的化验结果,采用湖南省主要农作物测土配方施肥手机专家系统和扬州测土配方施肥专家系统,分别制定早稻的精准施肥方案。对比试验结果表明:采用2个专家系统制定的施肥方案较习惯施肥有更好的增产效果,并且能减少化肥用量,降低了施肥成本,对于改变农民粗放的施肥习惯,改善生态环境也有较好的作用,适合大面积推广应用。比较2个专家系统,湖南省测土配方施肥手机信息专家系统更适于在耒阳市推广。
According to the results of soil nutrient test in Leiyang experimental site, through the mobile phone expert system of soil testing and formula fertilization for main crops in Hunan Province and Yangzhou soil testing and formula fertilization expert system, the precise fertilization schemes for early rice were formulated respectively. The results show that the fertilization scheme formulated by the two expert systems has better effect on increasing yield than the conventional fertilization, and can reduce the amount of chemical fertilizer and the cost of fertilization. It can also change the extensive fertilization habits of farmers and improve the ecological environment. It is suitable for large-scale popularization and application. Comparing the two expert systems, the mobile phone information expert system of soil testing and formula fertilization in Hunan Province is more suitable for popularization in Leiyang City than Yangzhou soil testing and formula fertilization expert system.
