摘要
用4种橡胶园土壤进行温室盆栽试验,研究4种土壤的养分变化及其对橡胶苗生长的影响。结果表明,施肥处理与不施肥处理,土壤速效氮与速效磷变化幅度均表现为砂页岩最大而玄武岩最小,土壤速效钾变化幅度均表现为浅海沉积物>玄武岩>砂页岩>花岗岩,从总体上看,不同母质发育的土壤对橡胶苗的苗高、地径生长的影响显著,其中以砂页岩发育的土壤上的橡胶苗生长最好,而在浅海沉积物土壤生长最差。
Rubber seedlings were pot cultured with and without fertilizer on the soils derived from 4 different parent materials to observe their growth. The results indicated that in fertilizer treatment and non-fertilizer treatment, the change in soil available N and available P was highest in sandy shale and lowest in basalt, and that the change in soil available K was in the order of neritic deposit 〉basalt 〉 sandy shale 〉granite. Generally soils derived from different parent materials gave notable impact to the development of plant height and stem diameter at the base. Rubber seedlings grew the best on the sandy-shale derived soil but the poorest in the niritic deposit derived soil.
