【摘要】 单季晚稻计算机配方施肥研究，包括单季晚稻简化施肥技术，产量因子效应，微机程序设计等内容。通过研究结合上海地区实践已获得较好结果，中试和大田推广表明：采用微机配方施肥，既能使水稻平衡吸收养分，达到高产稳产，又能省工、省肥、减少污染，每公顷增产粮食２２５～３００ｋｇ，节约化肥（碳铵）２２５ｋｇ。更多还原

【Abstract】 Checked by the field practice in Shanghai area, our study on single cropping rice fertilization recommendation by computer, involving simplified fertilization techniques for single cropping rice, effect of yield factors and computer programming, achieved already good results. Field pilot experiments and extension trials indicated that the fertilization recommendation by computer can make rice absorb nutrients balancedly, reach high and stable yields as well as save labour and fertilizers and reduce environment pollution. As to the economic effects, the rice yield increased by 225～300 kg/hm2, and the fertilizer saving was 225kg/hm2 ammonium bicarbonate.更多还原
