Abstract:

In order to exploit humus resources in forest as soilless seedling substrates in Linzhi area and solve the lack of high quality substrates in vegetables seedling, we took larch litter as the main materials and took cattle manure, sheep manure, chicken manure and pig manure as the adjunct materials to form several substrate formulas according to volume ratio. Using ‘Jinchun 4’ as study materials, we studied the effect of different substrate formulas on cucumber seedlings’ morphology indexes. The results showed that the substrates formula which used the pig manure and larch litter was best according to cucumber seedling rate, plant height, stem diameter, total leaf area, root length, plant stem-leaf fresh weight and root fresh weight. Especially, after using the best formula the average root fresh weight was 1.2-1.7 times higher than that of CK. Other formula substrates had some questions, which could not be used in production directly.
