应用微型电算机进行计氮施肥,是科学的施肥手段。为了摸索微型电算机在水稻生产上的应用和推广价值,1984年晚造,我们应用华南工学院设计的SL83施氮电算机进行水稻计氮施肥,证明效果良好,易于操作,很有推广价值。在实践中,我们还探索到用数学公式代替SL83施氮电算机,可大量节省购买该电算机的资金,更有利于广泛推广计氮施肥。 (一)电算施氮试验的经济效果试验结果表明,全县6个站按电算施氮的14块共13.41亩,比习惯法施氮的10.67亩均获显著增产。电算施氮的平均亩产为903.6斤,
Application of microcomputer for nitrogen fertilization, is a scientific means of fertilization. In order to explore the application and promotion value of microcomputer in rice production, in late 1984, we applied SL83 nitrogen computer designed by South China Institute of Technology for nitrogenous fertilization in rice, which proved to be effective and easy to operate value. In practice, we also explored the use of mathematical formulas instead of SL83 nitrogen computer, which can save a lot of money to buy the computer, more conducive to the widespread promotion of nitrogen fertilization. (1) Economic Results of Calculating Nitrogen Tests The results show that the total number of 14 stations in the six stations of the county is 13.41 mu, which is 14 units of nitrogen fertilizer, a significant increase compared with 10.67 mu of conventional nitrogen application. Calculate the average nitrogen yield of 903.6 kg per mu,
