摘要
1986～1988年,沈阳市水稻和玉米的氮、磷、钾肥料效应试验实践中,采用了3因素5水平的最优设计,并设2次或3次重复。在田间处理小区排列上汲取了拉丁方排列的特点,致使一个试验结果有多个组合统计,从中选优结果,使试验的成功率提高,非典型式的出现率降低,提高了现代回归设计肥料试验的效率。
An optimal design of 3 factors 5 levels was adopted for 3 years in the fertilizer effect test of nigtrogen, phyosphorus, and potassium about rice and corn in Shenyang. 2 or 3 time repetitions were Carried out in the design. The Charac- teristics of square design were also adopted in the plot arrangement of fileds treatment. So good method of analysis could be chosen with the experimental results. Both the mission success rate in the experiments and the efficiency of the ferlilizer test of the modern regression design were raised, while the rate of atypical turn-up were dropped.
