摘要: 对湖北江汉平原农田生态系统8种种植模式中Cu的输入、输出和平衡进行了分析.结果表明,农田Cu的输出主要是作物收获,其输出量占总输出量的85.9%~95.1%,流失和淋溶输出很少.农田Cu的输入主要是有机肥输入和降雨输入,其次是降尘、作物自然归还和灌溉,而种子种苗和无机肥输入占很少的比例.农田Cu的平衡分析表明,按照当地施肥习惯,菜田和水田Cu盈余较多,而旱地4种种植模式基本平衡.

Abstract: The cycling and balance of copper in8 cropping systems,i.e,wheat-rice,rice-rice,rape-soybean,rape-peanut,wheat-sesame,wheat-cotton,pepper-cabbage and radish-eggplant in Jianghan plain of Hubei Province were studied. The results showed that the main output of copper was crop harvesting,up to 85.9%~95.1% of total output,and the output of copper by field runoff and soil leaching was low. The main inputs of copper were organic fertilizer,rainfall,falldrop,and natural return.The inputs of copper from inorganic fertilizer and seeds (seedlings) were low. The balance analysis pointed out that copper had an accumulative trend in two patterns of rice and commercial vagetable ecosystem,and was in balance in upland field ecosystem.
