为缩短油松(Pinus tabulaeformis)的育苗周期,提高油松定值成活率,本文以心土、牛粪、草炭为原料,按比例制成不同基质,研究其对油松幼苗生物量和形态指标的影响。采用配伍组设计,对不同基质配比容器内的油松苗高、地径、主侧根数及鲜干质量等指标进行测定和分析。不同基质对油松容器苗的生物量和形态指标的影响差异较大。油松的形态指标在T5、T4、T1基质内长势良好,在T3、T6基质内的长势最差;基质T3、T5内的油松苗生物量情况最好,而基质T9内的生物量情况最差。经过综合对比,采用心土∶牛粪=3∶1(T5)制成的育苗基质最理想,建议更广范围内推广。
In order to shorten the seedling cycle of Pinus tabulaeformis and increase the survival rate of Pinus tabulaeformis, we made different proportions of soil matrix, cow dung and peat as raw materials to study the effects of Pinus tabulaeformis seedling biomass and morphological index Impact. The compatibility group design was used to measure and analyze the height, diameter, main root number and fresh weight of Pinus tabulaeformis seedlings in different matrix proportioning containers. The effects of different matrices on the biomass and morphological indexes of Pinus tabulaeformis seedlings varied greatly. The morphological indexes of Pinus tabulaeformis grew well in T5, T4, T1 matrices and the worst in T3 and T6 matrices. The biomass of Pinus tabulaeformis seedlings was the best in T3 and T5, and the biomass in T9 difference. After a comprehensive comparison, using soil: cow dung = 3: 1 (T5) made the best seedling matrix, it is recommended to promote a wider range.
