摘 要:
以特种玉米为指示作物的有机施肥,连续两年田间试验,结果表明:施肥后的土壤耕层氮、磷、钾养分盈亏幅度为1.9%~15.7%、2.6%~12.0%、-0.29%~0.13%,比单施化肥增加3.0~16.8、2.8~12.2、0.25~0.67个百分点;氮、磷、钾盈亏量与施肥投入量呈极显著正相关。参试的3种有机肥中,猪粪肥表现为土壤生态培肥效果比较好,施肥两年耕层土壤氮、磷、钾含量均有盈余,存量比例为0.17∶1.00∶0.04。

摘 要:
The two-year experiment results showed that the contents of nitrogen, phosphorus, potassium in treatments with manure application were higher than that of only fertilizers applied. The difference of N, P and K in treatments after applying manure was 1.9%-15.7%, 2.6%-12.0% and -0.29%-0.13% respectively, with the increase of 3.0% -16.8%,2.8%-12.2% and 0.25%-0.67% respectively. The proportion of them was 0.17:1.00:0.04.
