科学试验的目的,不仅在于认识客观世界,而且在于改造客观世界。在试验研究过程中,首先是通过调查、观察、接触事物的表征以及事物间的外部联系,形成印象,这是感性认识。但从感性认识到理性认识需要反复的实践和思考,需要有正确的试验、观察、比较和分析,才能认识事物的本质及其发展规律。因此,在试验研究工作中,试验技术和方法有着十分重要的意义。本文着重就林业田间试验设计和统计分析的一般性应用问题介绍于后。 The purpose of scientific experiments is not only to understand the objective world, but also to transform the objective world. In the process of experimental research, the first impression is formed through the investigation, observation, characterization of contact things and the external relations between things, which is perceptual knowledge. However, from perceptual understanding to rational understanding requires repeated practice and reflection, and requires correct tests, observations, comparisons and analyzes to understand the nature of things and their laws of development. Therefore, the experimental techniques and methods have very important significance in experimental research. This article focuses on the general application of forestry field trial design and statistical analysis in the post.
