| 摘要: |
| 中性亚硫酸铵造纸制浆废液(简称黑液),是一种有机无机混合肥料。黑液以含氮量为最高;钾次之;磷微量。此外,黑液还含有细纤维、还原糖、木质素以及亚硫酸根(SO32-等还原性物质[1,2,3]。黑液作为氮肥在水田施用,最为人们关注的是其中带进的还原性物质,它可能使土壤中还原性物质累积过多,从而对作物生长产生危害。为此,本实验在田间试验观察比较的 |

| THE EFFECT OFDRESSING PAPER PULPING EFFLUENTS FROM METHOD AMMONIUM SULFITE ON THE OXIDITION-REDUCTION POTENTIAL(Eh)OF THE RICE SOIL |

|
| Abstract: |
| The present pot experiment was established,in order to observe the dynamic changes of oxidition reduction potentiel of the paddy siil, which had been fertilized by straw paper pulping effluents from method ammonium sulfite for 2 years.At the same time,the influence of the given effluents upon the rice growing was observed also. After dresuing the present effluents,the Eh value of the rice soil moved downwand steeply and immediately.Generally it oscillated in a range from-200 to 300mv.And just on the second ... |
