Abstract: Using the seedlings as test material,experiments were carried out to study the effects of different matrix proportion on the nutrition growth of Prunus davidiana.The results showed that the values of plant height,stem diameter,biomass of Prunus davidiana seedlings which were planted in the mixed matrix of vermiculite and perlite (1:1) were the highest,and the values of those which were planted in the mixed matrix of clay soil and sand were the lowest.The results offer some references for soil-free cultivation of peach.

Key words: Prunus davidiana seedlings, soil-free cultivation, matrix, nutrition growth

摘要： 以毛桃幼苗为试材,研究不同基质配比对其无土栽培生长的影响。结果表明,毛桃幼苗栽植于蛭石与珍珠岩按1:1混合的基质中,植株株高、茎粗、生物量均最高,而在粘土与沙土混合基质中生长最差。本试验结果可供开展桃树无土栽培参考。
