Abstract

This experiment,conducted in Dengjiadongwu Village of Jiande City,Zhejiang Province,is mainly to study the growth of pecan seedlings and roots affected by different substrate and container.The results show that method of cultivate seedling effected the indexes of seedling diameter and seedling height,especially ordinary cultivating container,substrate types and removing embryos measures had some effect on root diameter,but had no association with the height of the root.The indexes of underground have no association with container types,but are effected by substrate types and removing embryos measures,especially using 40% turfs+40%pearlite+20%vermiculite as substrate and removing half of embryos,in this condition,the indexes reach the maximum.So,in the process of producing,we can choose ordinary cultivating container,40% turfs+40%pearlite+20%vermiculite as substrate and removing half of embryos,not only can we container-seeding get,which substrate ligther,roots stronger,but also root system developed insure the survival rate of forest planting.
