錢學森畝產万斤的最新科學實證--用数据计算和事实说话


我們都知道﹐錢老在西方呆了二十多年。剛回國時頭腦里常常使用英制單位計算。英美度量單位有“里”﹑“畝”﹑“寸”“尺”等。中國人為了區別與我們的華制度量單位﹐有時就加上一個前綴“英”。

一英制單位的畝相當於我們華制的6.07畝。如果錢老當時腦袋里潛意識用的是英畝計算﹐也就是說他的畝產万斤也就是華制畝產1647斤﹐即823公斤。

2009年10月28日﹐中國農業信息網登載“靈武農場万畝水稻平均畝產達到743公斤”(http://www.agri.gov.cn/dfxxlb/nxxxlb/t20091028_1372939.htm)

摘要如下﹕“日前從農墾靈武農場了解到,今年農場种植的2.5万畝“富源四號”优質水稻,平均畝產達到650公斤以上,其中由國家農業部實施的“万畝水稻高產攻關項目”,平均畝產經權威部門測產達到743公斤,在引黃灌區單產效益領先。”

2009年11月05日﹐江蘇新聞網報道“江蘇省水稻高產刷新全國紀錄 畝產近900公斤”(http://www.js.chinanews.com.cn/news/2009/1105/12167.html)

摘要如下﹕“平均畝產898.9公斤,最高畝產937.2公斤,兩項數据同時打破了全國稻麥兩熟主產區水稻產量紀錄。4日上午,江蘇省科技廳組織浙江大學、安徽省農委等單位的專家,對興化市農業技術推廣中心和揚州大學在該市釣魚鎮實施的水稻超高產精确定量栽培攻關田進行了實產驗收。記者了解到,目前江蘇省水稻畝產大約在550公斤,采用精确栽培技術,可以把平均產量提升至700公斤左右。(李 源)編輯:翔鳴”。

如果以上新聞沒有造假﹐“畝產近743-900公斤”即1486-1800斤。也就是一英制畝產九千到一萬兩千多斤。

這就說明錢老當年得科學計算和預測是非常正確的﹐而且當時還比較保守。

鷹永遠看得高看得遠(也許有時比雞飛得低)。
