摘要: 为了深入了解耕作措施对稻田耕层土壤的作用效果,笔者在前人研究结果的基础上综述了免耕、翻耕等不同耕作方式对稻田土壤物理性质包括容重、孔隙度、团聚体、水分、温度,土壤化学性质如氮、磷、钾、有机质和微量元素含量以及土壤生物学特性包括微生物、酶活性的影响,分析了不同稻作措施的优缺点。最后对稻田耕层的合理调控提出因地制宜,依据当地的气候、土壤条件、栽培模式选择合理的耕作方式;合理轮耕,免耕、翻耕和旋耕交替运作;配施绿肥和有机肥;推行节水稻作模式等建议。

Abstract: In order to have a deeper understanding about the effect of different tillage modes on paddy field, based on previous studies, the effects of different tillage modes including no-tillage, plow tillage etc. on soil physical properties, chemical properties and biological properties were summarized. The soil physical properties included soil bulk density, porosity, aggregate, moisture and temperature; the chemical properties included contents of nitrogen, phosphorus, potassium, organic material and trace elements; and the biological properties included microorganism amount and enzyme activity. The advantages and disadvantages of different tillage modes were analyzed. Finally, several suggestions were put forward for the reasonable regulation of paddy soil, such as choosing favorable tillage modes according to local weather, soil condition and cultivation modes; reasonably applying rotation tillage, alternatively applying no-tillage, plow tillage and rotary tillage; combing applying green manure and organic fertilizer and carrying out water-saving cultivation mode.
