本文采用正交试验设计方法,研究了刺槐能源林培育中的几个关键技术问题。结果表明,不同品种、不同栽植密度和不同覆盖措施对苗木成活率、苗木质量指标影响显著。在四个供试品种中,普通刺槐、四倍体刺槐和速生槐在当地均有较好的生长适宜性,但以普通刺槐,采用1.0 m×1.5 m的栽植密度,并用塑料薄膜覆盖为最佳培育方案,苗木成活率最高,质量最好。
In this paper, orthogonal design method was used to study several key technical problems in the cultivation of Robinia pseudoacacia forest. The results showed that different varieties, different planting densities and different covering measures had significant effects on seedling survival rate and seedling quality index. Among the four tested cultivars, Robinia pseudoacacia, Tetraploid Robinia and Sophora japonica had better growth suitability in the locality. However, with the common Robinia pseudoacacia, the planting density of 1.0 m × 1.5 m and the plastic film coverage Good breeding programs, the highest survival rate of seedlings, the best quality.
