阜阳市近郊耕地养分状况分析

以阜阳市近郊耕地土壤为研究对象,对土壤养分状况(主要是土壤有机质和氮、磷、钾)进行了分析和研究,初步掌握阜阳近郊耕地土壤养分的丰缺状况。总的状况是:土壤的有机质含量偏低,土壤表现为碱性,不太适合小麦等大宗农作物的生长,宜通过施肥进行改良;在速效性养分方面总体偏低,钾素表现出差异性,应重视大量元素的施用;在施肥中应根据土壤的具体状况、栽培作物和生育时期的情况进行灵活应用,合理施用。

Analysis on the Nutrients Status of the Arable Land in Suburb of Fuyang City

The nutrients situation(mainly the soil organic matter,nitrogen,phosphorus and potassium) of the arable land in suburb of Fuyang city was determined and analyzed,so the richness and shortage of the nutrients in these areas was learned.The general information was as follows: the organic matter in the soil was lower and the soil was alkaline,so it was not very suitable for the growing wheat and it should be improved by applying fertilizers.Similarly,the quick-acting nutrients were in shortage,and the content of potassium in the soil varies a lot.The application of macro-elements should be paid great attention.The application of the different fertilizers should be flexibly and rationally according to the soil situation,kinds of crops and their growing stages.
