新开水田土壤肥力特征及培肥途径研究

A DISCUSSION ON CHARACTERISTICS OF THE SOIL AND DEVELOPMENT OF THE FERTILITY OF THE RECLAIMED PADDY

新开水田土壤养分贫乏,物理性质不良,水耕植稻产量低.必须采取多种措施增施有机肥以提高土壤肥力,多犁多耙以降低渗漏,才有可能在较短的时期内改造成为高产稳产的农田.

Making scientific reseaches on the reclaimed paddy shows that there are some particularities such as low contains of organic matter,shortage of soil nutrient, high leakage, great clayey as well as bad physical properties of the soil. The better measures to improve the soil is to apply more organic fertilizer in order to raise the contains of organic matter, making more plough and more rake so as to promote the puddling to reduce the leakage of the soil before the plow sole forms. But the best way to develop the fertility of the reclaimed paddy is build upon a outstanding ecoagricultural project to improve the material circulation in system.
