土壤肥力与土壤结构状况有着密切的关系,以往的研究多偏重于旱地,近年来在国内外对水稻土的结构状况及其肥力意义也进行了一些工作.而水稻土的结构究竟有那些特性,其意义如何,还是一个急待解决的问题.土壤的肥瘦与整个剖面的构造密切相关,而耕层的结构状况对肥力影响更为重要,因此,我们选择了在肥力上有明显差异的几种水稻土耕层为对象,进行团聚体特性的研究,希望进一步说明水稻土耕层的结构特性及其对土壤肥力的影响和意义.
Soil fertility and soil structure are closely related to the past, more emphasis on dry land, in recent years at home and abroad on the structure of paddy soil and its significance of fertility also carried out some work.While the structure of paddy soil what are those characteristics, Its significance is still an urgent problem to be solved.The soil fat and lean is closely related to the structure of the entire section, and the structure of the topsoil is more important to the effect of fertility, therefore, we have chosen several obvious differences in fertility Paddy soil as the object of study, the characteristics of aggregates, hoping to further explain the structural characteristics of paddy soil and its impact on soil fertility and significance.
