1983—1986年测定山东省5318个表层土样及285个土壤剖面,DTPA—Mn或易还原态锰含量在不同土类和地貌分区有明显规律,而同一土类或地貌分区中两种有效态锰含量多不表现密切相关。棕壤、水稻土含锰量丰富,风沙土、潮土及部分砂姜黑土供锰不足。鲁东丘陵区含锰量丰富,鲁中山地丘陵适中,山前平原、湖沼平原局部偏低,滨海平原略偏低,黄泛平原为主要低锰区。在黄泛平原区中,河滩高地、决口扇形地及缓平坡地上的风沙土、质地粗而地下水位低的潮土是锰肥开发应用的重点。
From 1983 to 1986, 5318 topsoil samples and 285 soil profiles were determined in Shandong Province. The DTPA-Mn or easily-reducible manganese content had obvious regularity in different soil types and landform subdivisions, while in the same soil or topography, Manganese content is not closely related to performance. Brown soil, paddy soil rich in manganese content, aeolian sandy soil, Chao soil and part of the Shajiang black soil for manganese deficiency. Ludong hilly area rich in manganese content, Lu Zhongshan hilly moderately, piedmont plain, lakeshore plain low, the coastal plain is slightly lower, the Yellow River plain is the main low manganese area. In the Yellow River plain area, floodplain, burst sector fan and gentle flat slope windy soil, coarse texture and low groundwater level is the focus of the development and application of manganese fertilizer.
