天山北坡前山带不同基质配比对中国沙棘育苗的影响

Effects of Different Substrate Ratios on Hippophae rhamnoides L. Seedlings in the Front Mountain Belt of the Northern Slope of Tianshan Mountains

  • 摘要: 为了筛选天山北坡前山带中国沙棘适宜的育苗基质配比,以园土、腐熟羊粪、河沙为试验材料,采用随机区组试验设计,通过方差分析、主成分分析、逐步回归分析等,对比分析不同育苗基质配比下中国沙棘苗生理生长指标,对中国沙棘苗进行综合评价,揭示该地区苗的生长特性,筛选出较优的育苗基质配比。结果表明,不同育苗基质配比对中国沙棘的生长量和生理指标存在差异;中国沙棘最佳基质配比为园土:腐熟羊粪:河沙=6:2:2。

     

    Abstract: In order to select appropriate substrate ratio of Hippophae rhamnoides L. in the front mountain belt of the northern slope of Tianshan mountains, garden soil, decomposed sheep droppings and river sand were used as the experimental material. The physiological growth index of Hippophae rhamnoides seedling with different ratios of seedling substrates were compared and analyzed by means of variance analysis, principal component analysis, stepwise regression analysis, etc. Finally, a comprehensive evaluation of Hippophae rhamnoides L. container seedlings was made to reveal the growth characteristics of seedlings in this area, and to selected a better ratio of seedling substrates. The results showed that there were differences in the growth and physiological index of Hippophae rhamnoides L. in different seedling substrates. The optimum substrate ratio of Hippophae rhamnoides was: garden soil: decomposed sheep droppings: river sand =6:2:2.
