摘要：在浙江省建德市邓家东坞村进行不同基质和不同容器对薄壳山核桃苗木生长及根系生长影响的研究.结果表明:不同育苗措施对苗木地上部分苗木地径及苗木高度均有一定的影响,其中以普通育苗容器对苗木地径及高度影响最大,其值也最大,而基质类型和去胚尖措施对苗木地径也有一定的影响,但是对苗木高度均未表现出显著性差异.容器种类对地下部分各指标未表现出显著性影响,而基质类型及去胚尖措施对苗木地下部分各指标影响较大,其中以40%泥炭+40%珍珠岩+20%蛭石为基质及去1/2胚尖苗木根系长度、根系表面积及根系体积最大.在实际生产应用中,可选择普通育苗容器、40%泥炭+40%珍珠岩+20%蛭石为基质和去1/2胚尖的模式进行容器苗的培育,不仅可以获得基质较轻、苗木健壮的容器苗,同时其苗木根系发达,可大大提高造林成活率和保存率.
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.
