摘要: 研究了四川盆地丘陵区3个生态亚区近20年(1981~1999)农田养分平衡与土壤养分动态变化趋势。结果表明:各生态亚区农田氮素平均盈余59.59%、39.75%、11.12%;磷素平均盈余40%以上;钾素平均亏缺38%以上。根据3个典型县土壤养分动态变化,阐述了农田养分平衡状况对土壤养分的影响。

Abstract: The farmland nutrients balance and the dynamic changing tendency of soil nutrients were discussed during nearly 20 years(from 1981 to 1999) in three sub ecosystems zone of the hill of Sichuan basin.The results show that the nitrogen in farmland is surplus by 59.59%, 39.75% and 11.12%, the phosphorus are surplus over 40%, the potassiums are deficient over 38% on the average.According to the dynamic changing tendency of soil nutrients in three counties, the effects of farmland nutrients balance on soil nutrients are discussed.

Key words: Sichuan basin, nutrients balance, soil nutrients, dynamic changing
