摘要
Abstract
The investigation was carried out to assess the suitable planting media and plastic tray type for the production of quality seedlings of Sorbus amabilis. The growth, biomass and physiological indices of seedlings were studied using 6 different planting media and 4 plastic tray types. Results were shown as follows: Planting media exercised a significant effect on seedling growth. The best response in terms of seedling quality parameters was observed in planting medium of peat: ver-miculite compost in the ratio of 2; 1. Effect of plastic tray types on seedling growth was determined by seedling age. Plastic tray Tl with the smallest root volume might be used for 60d-old seedlings, when type hadnt exercised any restriction on root system and up-parts growth. For 90d old seedlings, there was an increase in seedling height, diameter, biomass, root system vigor and chlorophyll content as the planting depth increased,so T4 plastic tray should be used in planting for its optimal seedling growth. In terms of resource conservation, T2 might be used for its unremarkable difference with T4 in most of the quality parameters.关键词
