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 12 g/盆 (即 2 0 0 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 16 g/盆 (即 2 6 6 7mg/kg土 )
Based on the same chemical fertilizer, the different organic materiels were employed on the soil. The result show, the better increasing influence onthe 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).
