摘要
本试验采用猪粪作为有机基质,与椰渣、珍珠岩、锯末混合成基质,利用容器袋进行播种培育,之后采集标准株,对标准株的根系进行测定分析。通过对构树容器苗根系^([1])的研究,筛选出作为构树容器苗^([2])培育的最佳配比,为构树苗木生产提供参考。结果表明:Z1(猪粪∶椰渣∶珍珠岩∶锯末=4∶4∶1∶1)这个基质配方在构树容器苗根系的长度、根尖数、分叉数、连接数等指标上均有极好的表现,这些指标的数值越高,代表着根系的生长情况就越好,因此选择Z1作为构树容器苗的培育基质。
In this experiment,pig manure was used as the organic substrate,mixed with coconut chips,perlite and saw dust,and then used for the cultivation of Broussonetia papyrifera seedlings in container bags.The standard seedlings were then collected and their root systems were measured and analyzed.Through the study on the root system of the container seedlings of Broussonetia papyrifera,the best substrate formula for the cultivation of Broussonetia papyrifera seedlings in container bags was screened out.The results showed that,formula Z1(pig manure∶coconut chips∶perlite∶sawdust=4∶4∶1∶1) had the best performance in root length,root tip number,branch number,connection number and other indicators of the container seedlings of Broussonetia papyrifera.Therefore,formula Z1 was selected as the cultivation substrate of container seedlings of Broussonetia papyrifera.
