摘要 通过一系列的试验研究,揭示了碳酸盐草甸土基础地力与作物产量的关系.从此以充分利用农肥资源,进行改土培肥,合理使用化肥等措施.经10年努力效果显著,1. 6万亩的水、旱田地力提高,粮食产量提高,经济效益好转。 Through a series of soil investigation and fertilizing experiment,The relationship between crop yield and the soil fundamental fertility has been revealed in the clayey carbonate meadow soil.Using farm manure fully and fertilizers reasonably was proved to be good measures which increased the fertility of paddy soil and dry land,hence increased the crop yield.
