摘要
以蚓粪、椰糠、泥炭、珍珠岩、蛭石为原料,按不同比例混合,研究其对康乃馨出苗率、株高、茎粗、叶长、叶片数、分支数、地上部干重、地下部干重、根冠比、壮苗指数等生长指标的影响,筛选出最佳基质配方。结果表明:椰糠和蚯蚓粪明显地促进康乃馨的生长发育,以60%蚓粪+10%椰糠+30%混合矿物(珍珠岩:蛭石=1:1)处理综合效果最理想,最有利于康乃馨形成壮苗。所得到的复合基质的容重、总孔隙度、毛管持水量、通气孔隙度和pH均符合育苗基质的要求。
To investigate the effects of the mixture of vermicompost,coir,peat,perlite,vermiculite on the carnations emergence rate,plant height,stem diameter,leaf length,leaf number,branch number,aboveground dry weight,underground dry weight,ratio of root to shoot and strong seedling index,to find the best substrate formula.The results showed that coirc could significantly promote the growth of carnation,and the treatment of 80% vermicom-post＋10% coir＋30% additions（perlite∶vermiculite=1∶1） showed the best combind effect,most beneficial the formation of seedling carnation.The volumeweight,specific gravity,total porosity,capillary capacity,aeratin porosity and pH of vermicompost-formulated substrate consistent with the requirements of nursery substrate.
