摘要: 在施用等量无机肥的基础上,施用不同的有机物料。结果表明:泥炭对于提高土壤有机质与全氮含量的作用优于褐煤,且以12g/盆(即200.0mg/kg土)为好;但对小麦生长发育的促进和氮素利用的提高上,褐煤比泥炭更好,且以16g/盆(即266.7mg/kg土)为宜。

Abstract: Based on the same chemical fertilizer, the different organic materiels were employed on the soil. The result show, the better increasing influence on the soil organic matter and total N were found in the turf, and leveled in 12g/pot (namely 200.0mg/kg soil). But, the better increasing effect on the growth and N utilization of wheat were found in lignite, and the feasible dosage was 16g/pot (namely 266.7mg/kg soil).
