Soil Physical and Chemical Properties of Cunninghamia lanceolata-Aleurites Montana Mixed Forestand Cunninghamia lanceolata Pure Forest with Different Age
摘要
Abstract
Soil physical and chemical properties in the depth of 0-60 cm layers under C.lanceolata-A.Montana mixed forest and C.lanceolata pure forest 3-5 aged were studied on the basis of field sampling and laboratory test.The results showed that:The bulk dcnsity and moisture capacity of C.lanceolata-A.Montana mixed forest were significantly higher than that of C.lanceolata pure forest in juvenile,it meanet the mixed stands of C.lanceolata and A.Montana improved soil physical properties.The pH value of different forest was 4.22-4.53 for C.lanceolata pure forest,4.41-4.85 for the C.lanceolata-A.Montana mixed forest.Mixed stand of C.lanceolata and A.Montana assuaged soil acidification.The soil nutritions would be concentrated in the surface layer in C.lanceolata-A.Montana mixed forest and C.lanceolata pure forest.There was significant difference in organic matter content of the pure and mixed forest.In addition to some soil chemical properties including hydrolysis nitrogen,total potassium content,available potassium content of mixed stand of C.lanceolata and A.Montana were lower than C.lanceolata pure forest aged 4,total nitrogen,Total phosphorus content and available phosphorus content of C.lanceolata-A.Montana mixed forest were higher than that of Cu.lanceolata pure forest,but significant difference were not found.Therefore,in the mixed plantation,soil nutrients were further improved.关键词
