【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 )为宜更多还原

【Abstract】 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).更多还原
