补充资料:褐土
褐土 cinnamon soil 发育于地中海型气候区或欧亚大陆东部暖温带季风气候区半干旱森林灌木下的土壤。又称褐色森林土。广泛分布于西欧地中海沿岸,非洲北部、俄罗斯、美国西南部、墨西哥北部、南美西部,澳大利亚也有存在。中国主要分布在燕山、太行山、吕梁山等山地,陕西中部、山西南部、河南西部等盆地,以及山东的济南至潍坊一带。褐土的主要特征是:表土呈褐色至棕黄色;剖面中、下部有粘粒和钙的积聚;呈中性(表层)至微碱性(心底土层)反应。土壤剖面构型为有机质积聚层-粘化层-钙积层-母质层。中国境内褐土多发育于碳酸盐母质上,具有明显的粘化作用和钙化作用。呈中性至碱性反应,碳酸钙多为假菌丝体状广泛存在于土层中、下层,有时出现在表土层。褐土分为典型褐土、淋溶褐土、碳酸盐褐土和潮褐土4个亚类。褐土除适宜农作物生长外,也适宜于栽培苹果、梨、枣、杏、柿等果树作物。但为防止旱、瘠和水土流失的影响,须加强水土保持、培肥和灌溉措施。 |
