风沙土农田培肥地力措施研究——以宁夏回族自治区为例

Study on the measures of fostering fertility of aeolian sand soil in farmland—A case study from Ningxia Hui Autonomous Region

  • 摘要: 试验研究宁夏回族自治区大田风沙土培肥途径结果表明,各种培肥措施均能明显提高风沙土农田土壤全量养分和速效养分含量,且对土壤团粒结构有较明显影响,其中施有机肥处理影响最大,显著提高土壤蓄水性能。N、P、K配施处理土壤有机质、速效氮、速效磷和速效钾增幅较大。与单施无机肥和单施有机肥相比,有机肥与无机肥配施培肥措施可显著提高土壤全量养分和速效养分。

     

    Abstract: The measures of fostering fertility of aeolian sand soil in farmland are studied through field experiment. The results show that all the measures of fostering fertility can increase the whole and the available nutrients distinctly, and affect the dumpling structure of soil obviously. The organic fertilizer treatment is the best of all, and the capacity of restraining water of soil increases. A cooperative application of N, P and K can increase the contents of organic matter, available N, available P and available K. Compared with fertilizing solely inorganic or organic fertilizer, the cooperative fertilization of inorganic and organic fertilizer can improve the whole and available nutrients of soil.
