Abstract: This paper puts forward the suggestions on plot area and yield estimation methods adopted in the standardized field experimental design and forage yield measurement in view of the problems existed in the published papers such as extreme small plot and sampling areas and absent consideration of marginal effect in field design and forage yield estimation,etc.

Key words: Field experimental design, Plot area, Marginal effect, Yield estimation method

摘要: 针对已发表的论文中有关牧草产草量田间试验设计中存在的小区面积过小,测产方法中未考虑边际效应的影响以及取样测产样方面积过小等问题,提出规范田间试验中的小区面积和测产方法的建议。

关键词: 田间试验设计, 小区面积, 边际效应, 测产方法
