摘要/Abstract

摘要： 在两种肥力条件下设置超高产栽培模式(SH)、高产高效栽培模式(HH)、农民习惯处理(FP)和不施肥对照处理(CK)4种栽培管理模式的定位试验,研究了以肥料投入为主要影响因素的不同栽培管理模式对黄淮海区域不同肥力农田耕层土壤团聚体组成及其碳、氮分布的影响,为通过培肥土壤实现小麦-玉米周年可持续增产增效提供技术支持.结果表明: 与低肥力田块(LSF)相比,高肥力田块(HSF)耕层土壤团聚体的平均质量直径和几何平均直径高、分形维数低,有利于大团聚体的形成与稳定,各级团聚体的有机碳和全氮含量较高.优化施用氮磷钾肥、配施有机肥可增加耕层土壤团聚体的粒径、降低其分形维数,促进大团聚体的形成与稳定,对高肥力田块的影响大于低肥力田块;二者亦可提高有机碳和全氮在大团聚体中的含量与分布,其中,对＞5 mm团聚体的贡献率的影响在低肥力田块大于高肥力田块,对5～0.5 mm的各粒级团聚体的贡献率的影响在高肥力田块优于低肥力田块.

Abstract: The long-term experiments were conducted at two locations with different soil fertility. There were four treatments, including super high-yielding cultivation treatment (SH), high-yielding and high efficiency cultivation treatment (HH), local farmer’s practice (FP), and control (CK), respectively. The field experiments were established to study the effects of different cultivation practices on composition, carbon and nitrogen distribution of tillage layer soil aggregates in different soil fertility, with the aim of proposing technological approaches to enhance soil fertility and achieve the sustainable development of increasing yield and efficiency in wheat-maize ecosystem. The results indicated that compared with treatments in low soil fertility (LSF), same treatments in high soil ferti-lity (HSF) had the higher mean mass diameter and geometric mean diameter, contents of organic carbon and total nitrogen, and lower fractal dimension in dried soil aggregates at soil tillage layer, which was beneficial to the formation and stability of large aggregate. Optimizing application of NPK fertilizers and the application of combined chemical fertilizer with organic fertilizer could increase the diameter of soil aggregate, reduce the fractal dimension of aggregate and promote the formation and stability of large aggregates, and the effect on HSF was greater than that on LSF; also they could improve the content and distribution of organic carbon and total nitrogen in large soil aggregate, the contribution rate to >5 mm aggregate in LSF was greater than in HSF, while the contribution rate to 5-0.5 mm aggregates in HSF was greater than in LSF.
