本文对新西兰两个农场相邻地块的22个土壤特性进行了分析,目的在于探讨生 物动力型、传统型和连作草地型3种耕作制度对土壤质量的影响。草地的生物学特性 普遍高于生物动力型和传统型地块,生物动力型菜地的物理、生物、化学特性优于传 统型菜地。土壤化学和生物特性的重量法数据换算为体积法数据后,菜地及其相邻草 地的绝大多数特性值,仍保持着统计学上的显著性,而农地及其相邻草地的多数特性 值变得不再显著差异。以一定的表土厚度为单位表示体积法数据,不利于低容重厚表 土与大容重薄表土两种土壤的分析比较。故应以土壤层次(完整A层或A层与B层)来 表示。无论采用何种分析方法,都应该强调土壤特性的生物学或生态学上的意义。
In this paper, 22 soil characteristics of two neighboring New Zealand farms were analyzed in order to explore the impact of the three farming systems of biodynamic, traditional and continuous grassland on soil quality. The biological characteristics of grassland are generally higher than that of biodynamic and traditional plots. The physical, biological and chemical characteristics of biodynamic vegetable fields are superior to those of traditional vegetable fields. Gravimetric data of soil chemistry and biological properties, after conversion to volumetric data, remained statistically significant for most of the values of the vegetable field and its adjacent grasslands, whereas the majority of agricultural land and its adjacent grasslands The characteristic values become no longer significant differences. The volumetric data is expressed in terms of a certain amount of topsoil thickness, which is not conducive to the analysis and comparison of two types of soils with low bulk density and thick bulk. It should be soil level (complete A layer or A layer and B layer) to represent. Regardless of the analytical method used, the biological or ecological significance of soil properties should be emphasized.
