摘要
较为详细的介绍了位于陕西省长武县旱塬上 ,规模宏大的两个长期定位试验——长武轮作定位试验 (36个处理 ,10 8区 ,占地 874 1m2 )和肥料定位试验 (2 4个处理 ,72区 ,占地 2 2 0 0 m2 )的设计方案与管理方法。试验布设于 1984年 ,过去的 18年里在旱作产量效应、肥料合理施用、土壤培肥机理、硝态氮的累积规律、土壤干层形成理论等方面 。
The design plan and management of two long term position experiments are descr bed in details,Changwu rotation fertilized position experiment and Changwu fertilizer position experiment, which located in dry highland of Changwu of Shaanxi Province. Up to today, these experiments have been conducted for 18 years, many publications and valuable stage results had been achieved. Main advances concentrated on effect of yield, optimized fertilization,mechanism of soil fertility formation, nitrate accumulation law, soil dry layer theory and so on.
