刈割测定牧草产量是天然和人工草地研究中最常用的一项技术,也是人们认为最准确的测定方法。但是,该法不仅浪费工时而且对样地植被有一定破坏性。为此,人们一直努力寻求一种无需刈草而通过迅速测定一些与牧草光合产量相关的参数来预测牧草光合
Mow cutting is one of the most commonly used techniques in both natural and artificial grassland research and is considered to be the most accurate method of measurement. However, this method not only wastes working hours but also destructs the sample plots. For this reason, people are always trying to find a way to predict forage photosynthesis by rapidly determining some parameters related to forage photosynthesis rate
