林业方面的很多试验,如对某树种速生丰产和壮苗培育技术措施的探索,提高造林成活率的研究,某些树种(或品种、类型)间的对比试验以及选、育种原始材料的评比鉴定等等,都需要逋过田间试验进行。因此,它也和调查工作一样是林业试验研究的重要手段之一。一、进行田间试验的原则要使一个田间试验能真正反映事物的客观规律,能为生产上所应用,同时又能最大限度地减少工作量,也就是说:能多、快、好、省地进行试验,必须满足以下的基本要求:
Many experiments in forestry, such as the exploration of technical measures of fast-growing and strong seedling cultivation of some tree species, the research of improving the survival rate of afforestation, the comparative experiment of some tree species (or varieties and types), and the appraisal of selection and breeding original materials And so on, all need to go through field trials. Therefore, it is also one of the important means of forestry pilot research as well as the investigation work. First, the principle of conducting field trials To make a field trial can truly reflect the objective laws of things can be used for production, while minimizing the workload, that is: to more, faster, better, The test must meet the following basic requirements:
