【摘要】采用统计学的方法,研究了湖北省主要农区近30年来耕地土壤肥力变化情况。结果表明,土壤酸化明显,土壤有机质、速效钾下降,土壤速效磷、碱解氮增加,尤其土壤速效磷显著增加。同时,提出了合理利用耕地、保护土壤肥力的技术措施。更多还原

【Abstract】 The paper studied the changes of soil fertility of cultivated land in major agricultural areas in Hubei province for nearly 30 years by using statistical methods. The results indicated that soil acidification is apparent and soil organic matter and available potassium are declining; available phosphorus and alkali-hydrolyzed nitrogen are increasing, especiallly for available phosphorus significantly increased. At the same time the paper puts forward technical measures for rational use of soil fertility of cultivated land.更多还原
