摘要
以华北落叶松为研究对象,采用随机区组试验设计研究了不同量污泥处理对华北落叶松幼苗生长的影响。结果表明,7.5 kg/m2处理对幼苗生长影响最大,株高和地茎净增量最大,成活率也最高,且幼苗生长旺盛,针叶嫩绿,长势明显优于对照和其他处理。因此,在进行华北落叶松育苗时,可采用7.5 kg/m2城市污泥处理。
The influence of city sludge in different amount on the growth of Larix principis-rupprechtii Mayr seedlings were studied using randomized block design.The results showed that the 7.5 kg/m2 treatment had the largest effect on the seedlings,which grew exuberantly showing the highest net growth of height and roots and the highest survival rate.The seedlings with the treatment grew significantly better than the control and other treatment.Therefore,7.5 kg/m2 treatment using city sludge can be used when the L.principis-rupprechtii Mayr seedling was cultivated.
