不同容器和配方基质对苹果苗生长的影响

通过开展三项独立性关联试验，研究了4种容器材质、3种容器规格和13种配比基质对苹果容器苗生长产生的不同影响。研究结果表明，塑料袋和无纺布袋是栽植苹果苗比较经济实用的容器；苹果苗木培育只能在一定程度上缩小容器体积，直径20 cm、高30 cm规格的容器较适合1~2 年生苹果苗木的栽植；从农林废弃物资源综合利用角度出发，炉渣、玉米秆、花生壳、菌渣、稻壳、麦秆、豆秆、生木屑、腐熟木屑、稻壳炭以及贝壳粉等11种资源中，炉渣、菌渣和腐熟木屑均可以代替果园土作为苹果苗无土栽培基质。

Impact of different container and growing media on the growth of apple seedlings

We conducted three independent but associated tests to study the impact of 4 container materials, 3 container sizes and 13 kinds of growing media on the growth of greenhouse apple seedlings. Results show that plastic and non woven bags are more economic and practical containers to plant apple seedlings. Apple seedlings cultivation volume can only be contracted to a certain degree, 20 cm diameter and 30 cm height container suitable for 1~2 years apple seedlings growth. From the perspective of comprehensive utilization of agriculture and forestry waste resources, cinder, mushroom residue and rotten sawdust can serve as apple seeding soilless cultivation media substituting orchard soil among the 11 resources such as cinder, corn stalks, peanut shells, mushroom residue, rice husk, straw stalk, bean stalk, sawdust, rotten sawdust, rice husk carbon and shell powder.
