不同土壤条件对槐树生长和生物量的影响

Effect of Different Soil conditions on Growth and Yield of Sophora japonica L.

对4种不同土壤(水稻土、棕色石灰土、沙土、旱地土)中槐树幼苗的生长、生物量分配进行比较研究。结果表明:在槐树的生长量和生物量方面,棕色石灰土、水稻土与旱地土、沙土间均有显著差异,其大小顺序是:株高为棕色石灰土>水稻土>旱地土>沙土;地径为水稻土>棕色石灰土>旱地土>沙土;生物量为棕色石灰土>水稻土>旱地土>沙土。表明棕色石灰土和水稻土比较适合槐树生长。

Based on four different soil conditions （ paddy soil , brown calcareous soil, sand and upland soil ） , Sophora japonica seed- ling growth, and biomass comparative studies, the results showed that：brown calcareous soil, paddy soil growth and biomass and up- land soil, and the sand were significantly different for the growth and biomass; it followed the following order： brown calcareous soil 〉 paddy soil 〉 upland soil 〉 sand ; the ground diameter order was ： paddy soil 〉 brown calcareous soil 〉 upland soil 〉 sand; biomass order was ： brown calcareous soil 〉 paddy soil 〉 upland soil 〉 sand. Consequently, the brown calcareous soil and paddy soil were more suitable for the growth of Sophora japonica.
