甘肃农业大学校园土壤理化性状及改良初探

A Preliminary Study on Soil Physicochemical Properties in Campus of Gansu Agricultural University and Its Improving Measures.

对甘肃农业大学校园土壤进行了理化分析,表明缺氮及有机质、盐分含量高是利用的主要限制因素。结合学校的具体情况,提出改良土壤的五项措施,即:种植绿肥、覆盖、引洪灌溉、增施有机肥及加强耕作。

based on the results obtained, the soil in campus of Gansu Agricultural University showed lack of nitrogenous element and organic matter and high content of salt. These were the main restrictive facters for using it. According to the specific soil conditions of Gansu Agricultural University, we point out five measures to improve the soil: growing green manure, covering, irrigation by chanelling floodwater, getting a raise in spreading organic manure and strengthening tillage.
