“土壤识别与优化施肥”研究成果,1987年获国家发明三等奖,同年列入国家星火计划项目之一在福建实施。优化施肥是依据省化肥试验网1100多个水稻田间试验结果,应用系统识别和结构优化方法建立起合理施肥的数学模型,通过大型计算机运算后编写程序,输入稻田专用的“土壤识别与优化施肥微型计算机”。这样,便可不行土壤测试,只需农民提供某田块前一年同季稻作的施肥量和产量输入微机,它在2～3分钟内便可算出当年该田块的最高产量(即“优高”)和最佳效益产量的施肥量(即“优经”)。
“Soil Identification and Fertilization” research results, in 1987 won the third prize of national invention, included in the same year the national Spark Program one of the projects implemented in Fujian. Optimized fertilization is based on the fertilization experiment network of more than 1,100 rice field test results, the application of system identification and structure optimization methods to establish a reasonable fertilization mathematical model, through the preparation of large computer program after the input paddy field-specific “Soil Identification and Fertilization Micro computer”. In this way, the soil test can be done without inputting the amount of fertilizer and the yield of the same season paddy into the microcomputer just before the farmer provided the same paddy in a year. In 2 or 3 minutes, the highest yield of that field block can be calculated (ie “ Excellent high ”) and the amount of fertilizer with the best yield (ie“ superior ”).
