- Abstract:
-
In order to enrich the plant resource pool of soil and water conservation and improve its fragile ecological environment in eroded red soil area of South China, the growth adaptability of Forsythia, a fine eco-economic shrub, was studied in this area. Forsythia suspense, Forsythia giraldiana, Forsythia ovata, Forsythia mandshurica, Forsythia viridissima and Forsythia suspensa Vahl. var. sieboldii Zabel were selected as experimental plants, their cutting seedlings were planted in Quaternary red soil of southern China. Based on the investigation of survival rate and surviving seedling growth status after 100 days, we evaluate their growth adaptability in Quaternary red soil in southern China. The results show that:(1)under the four planting measures, the average survival rate of F. suspense Vahl. var. sieboldii Zabel is the highest(86.9%), followed by F. viridissima and F. suspense, which are 60.3% and 56.5%, respectively; three planting measures such as plastic mulching(PM), lime treatment(LT), combination of lime and plastic mulching(LPT)can significantly affect the survival rate of Forsythia plants;(2)varieties of Forsythia have very significant effects on underground/aboveground growth indexes, while planting measures only have very significant effects on aboveground leaves, their interaction has very significant effects on three growth indexes except the total root length; moreover, statistical results of underground/aboveground growth indices of surviving seedlings of Forsythia show that the root dry weight, total root length, leaf dry weight and leaf area of F. viridissima are the largest, followed by Forsythia suspensa, while all indices of F. ovata are the smallest;(3)the comprehensive evaluation of adaptability of Forsythia suspensa shows that F. viridissima belongs to high adaptability, Forsythia suspensa and F. suspense Vahl. var. sieboldii Zabel belong to moderate adaptability, while F. giraldiana, F. ovata, F. mandshurica and F. viridissima have relatively poor adaptability. These results can provide scientific basis for the introduction and cultivation of Forsythia plants in the eroded red soil area of southern China.
