摘  要：
通过对上海郊区青紫泥类型土壤的大量田间试验、室内模拟试验、土壤分析和长期定位试验等研究,对青紫泥类型土壤供氮、磷、钾进行模式化处理,同时对早稻的产量和肥料用量、品种与产量、移栽时间与产量进行了系统研究和调查,形成供计算机编制施肥量方案的参数。并用BASIC语言编制成包括地区、品种、茬口、移栽期、土壤有机质等9-10个因素的计算机施肥程序。利用这个程序可计算该地区农户早稻的施肥量方案。经过两年田间小区试验和一年的大面积早稻试验,统计结果有较好的一致性。平均偏差小于5-10％。

摘  要：
On the basis of large amount of field experiment. Simlated tests in doors, Soil analysis and long term rocalization experiment, nitrogen, phosphorus and potessium supply capacities of water-logged paddy soil in shanghai suburbs were processed in unified model. At the same time, a systematie study and investigation on the rela- tionships between early-rice yield and fertilizer amount, Variety and yield, transpla- nt time and yield was made to form large numbers of parameters for computer to formulate program of applying fertilizer amount. This program formulated by compu- ter including locality, variety, farmer crop, transplant time, soil organic matter and so on nine to ten factors may be used by the farmers in that area to calculate their fertilizer amount on early rice. A good statistic result has been gotton in two years plot trials and one year early rice field experiment in large area. Average difference is less than 5-10%.
