连续十年施肥对水稻土肥力的影响

Effect of Ten-year Succesive Fertilizer Application on the Soil Fertility of Paddy Field

  • 摘要: 人工淹水形成水稻土特有的环境条件。每年占水稻生物量15%的根茬及其丰富的水生生物自然归于土壤。既补充了碳源,又归还了部分营养成分,使得水稻土能维持一定的肥力水平。施用化肥缓和了土壤三要素取出的亏缺程度,改善了土壤的营养条件,有利于加强根系的代谢活动和提高根茬的归还量,所以土壤理化和生物特性相对得到一定程度改善。在化肥基础上配施有机肥,对于土壤理化和生物特性具有进一步显著改善的效果,由此可见,为了快速培肥地力,仍需提倡走“有机与无机相结合”的道路。
    Abstract: Under the environmental conditions formed by artificial flooding, the roots and stuble, which were about 15% rice biomas, as well as plenty of apuatic living things were returned into paddy soil every year, not only enriching the carbon sources but also replenishing nutrient composition in the soil. It mabe paddy soil maintain its fertility to some extent. Applying mineral fertilizer could mitigate the N. P. K. deficience caused by absorption of rice plant, and improve the nutrient level of the soil, facilitate the metabolism of rice roots and increase in amount of the root-stuble returning into soil. Applying inorganic fertilizer with the organic manure could significantly improve the physical, chemical and biological prporties of the soil. Because the paddy soils were poor in China, infarming practice, the "organo combining inorgano" application model should still be popularized, especially in returning rice straw into paddy field.
