研究了椰壳配制的基质对生菜幼苗生长发育的影响。结果表明,基质的配比椰壳∶蛭石∶腐植酸为4∶1∶1时,生菜幼苗的叶面积、株高、茎粗、根冠比、壮苗指数均显著优于其他比例的基质。该基质培育的生菜幼苗的干重也较其他处理呈明显差异(P<0.05),生物量增加效果显著。在实际生产中建议采用该比例的育苗基质进行生菜育苗。 The effects of coconut shell matrix on the growth and development of lettuce seedlings were studied. The results showed that leaf area, plant height, stem diameter, root / shoot ratio and strong seedling index of lettuce seedlings were significantly better than that of other proportions when the substrate ratio of coconut shell: vermiculite: humic acid was 4:1:1 . The dry weight of lettuce seedlings cultivated in this substrate was also significantly different from other treatments (P <0.05), and the effect of increasing biomass was significant. Proposed in the actual production of the proportion of nursery substrate lettuce nursery.
