施肥和土壤调理剂对酸性旱地红壤的修复效应
Restoration Effect of Different Fertilization and Soil Conditioner on Eroded Red Soil
摘要
Abstract
The pot experiments were conducted continuously for four years to study the effect of inorganic and organic fertilizer and soil conditioner on eroded red soil. The result showed that the soil nutrient content of CK treatment was lower than that of fertilizer treatments NPK, NPKM, NPKR1 and NPKR2. Treatment NPKM could increase the content of soil organic and available nitrogen significantly, NPKR2 could increase the content of soil available phosphorus and potassium significantly. Each fertilizer treatment could increase soil CEC and ECEC, treatments of NPKR2 and NPKM increased ECEC most significantly. Each fertilizer treatment improved the acid-base buffer capacity, the best two treatments were NPKR1 and NPKR2. Biomass of soybean and rape under fertilizer treatments was significantly higher than CK, moreover, biomass of NPKM was very significantly higher than CK and other 3 fertilizer treatments. However, yield of crops in different seasons were unstable which indicated that fertilizer and soil conditioner could not gain relatively satisfactory effect of eroded red soil and reach the high yield of crops in a short time.关键词
