废菌棒复合基质对3种阔叶树容器苗生长的影响

利用经发酵消毒后的黑木耳和香菇菌棒废弃物,设计与泥炭、谷壳的不同配比基质处理,研究其对红豆树、木荷和黄连木3种容器苗生长和芽苗移栽成活率的影响。结果表明:不同树种对废菌棒复合基质的生长反应显著,其芽苗移栽成活差异也很大;当废菌棒量不超过20%、谷壳不低于40%时其容器苗生长量和芽苗移栽成活率较好,接近于生产上常用的60%泥炭+40%谷壳的对照配比基质处理,其中20%废黑木耳菌棒+40%泥炭+40%谷壳为最佳的基质配方,20%废香菇菌棒+40%泥炭+40%谷壳和40%废黑木耳菌棒+30%泥炭+30%谷壳次之;随着配比基质中废菌棒量的增多和谷壳量的减少,3树种容器苗的苗高、地径生长和芽苗上袋成活率呈明显的降低趋势;比较分析表明,配比废黑木耳菌棒的复合基质其容器育苗效果优于配比废香菇菌棒的基质处理,这主要是由于香菇菌棒颗粒小而易吸水,透水透气性差的缘故。

Effect of Compound Substrates on Growth of Three Species of Container Seedlings

Experiment were conducted on the effect of different substrates on growth and survival rate of container seedlings of Ormosia hosiei,Schima superba and Pistacia chinensis.Substrates had different ratio of waste compost from mushroom cultivation,hull chaff.The result showed that different tree species expressed significant differences on growth and survival rate.The growth and survival rate of container seedlings were better when the amount of compost less than 20% and that of hull chaff less than 40%,simila...
