本试验从1984年开始,苗期采用随机区组设计,造林采用4×4平衡格子设计,对本地和外地引进的16个漆树(农家)品种进行了品种栽培试验,以观测不同漆树(农家)品种在我地的生长,产漆优劣、产漆量情况。本报告以苗期生长量和1987年底幼树生长量数据进行统计分析,说明各品种苗期树高、地经生长量存在极显著差异;造林后三年幼树生长量有差异比较苗期不明显,并用SR检验了各品种间生长量差异程度。
This experiment was started in 1984 and was designed by random block design at the seedling stage. The 4 × 4 balanced grid design was used for afforestation. Sixteen cultivars of cultivated Rhus typhina (farmed land) introduced locally and overseas were cultivated to observe the effects of different Rhus typhina Variety in my growth, the advantages and disadvantages paint, paint production situation. The data of seedling growth and the growth of young trees at the end of 1987 were statistically analyzed, which showed that there was a significant difference in seedling height and seedling growth among all varieties. Obviously, SR was used to test the degree of difference in growth among the varieties.
