“土壤识别与优化施肥”功能微机,最近在厦门,由航空部主持召开的鉴定会上通过部级鉴定。专家们一致认为,该项成果使“土壤识别与优化施肥”新技术能迅速转化为生产力,该机具有国际先进水平,建议申报国家发明奖。由我院研究员、院长刘中柱和航空部602所高级工程师刘夏石合作研究的“天地”牌—1型计算机。可以在不进行土壤化验的条件下,由农民提供这块田前茬水稻的施用氮磷钾和产量,就可计算出当年这块田土壤可供给水稻的氮磷钾量和施用氮磷钾后的利用率,从而计算出为了取得最高产量和经济产量应该施用的氮磷钾数量,并预报可以取得的产量.整个计算仅需2～3分钟。
“Soil identification and optimization of fertilization,” the function of microcomputer, recently in Xiamen, Ministry of Aviation presided over the appraisal meeting at the ministerial level appraisal. Experts agreed that this result will enable “soil identification and fertilization,” the new technology can be quickly transformed into productivity, the aircraft has the international advanced level, it is recommended to declare the national invention award. By our researcher, Dean Liu Zhongzhu and aviation department 602 senior engineer Liu Xia Shi cooperation research “Tiandi” brand -1 type computer. It is possible to calculate the amount of nitrogen, phosphorus and potassium available for paddy soils in this field and the amount of nitrogen, phosphorus and potassium applied by the farmer before the application of soil nitrogen, phosphorus, To calculate the amount of NPK that should be applied in order to obtain the highest yield and economic yield and to forecast the yield that can be achieved.The whole calculation takes only 2 to 3 minutes.
