文章通过对湘中红壤丘陵水土保持生态修复树草种生长量进行对比试验研究,初步筛选了桤木、马尾松、枫香、杉木、板栗、金银花、葛藤、萱草、苏丹草等树草种;桤木、马尾松和枫香等树种在疏林、纯林地补植中适应性较强;试验初期生长量较大的退耕还林模式依次为杉木水保林模式、马尾松水保林模式和板栗经果林模式;萱草和苏丹草在本区具有一定的适应能力。
In this paper, comparative experiments were conducted on the growth of soil and water conservation rehabilitated tree species in hilly red soil region of Hunan Province. The tree species of Alnus cremastogyne, Pinus massoniana, Liquidambar formosana, Chinese fir, chestnut, honeysuckle, kudzu, hemerocallis and sudangrass were screened out. Alnus cremastogyne, Pinus massoniana and Liquidambar formosana were more adaptable in sparse forest and pure forest land replanting. The model of returning farmland to forest with large amount of growth in the initial stage of experiment was Chinese fir forest water conservation forest model, Masson pine forest water conservation forest model and Chestnut through the fruit forest mode; Hemerocallis and sudangrass in this area has some adaptability.
