摘要
1985年选择位于黄土残塬丘陵区的彭阳县洞子墳村进行农田改制试验,经过4年实施,该试区11540亩耕地粮食平均亩产从50kg提高到158kg,人均产粮从241kg增加到740kg;与此同时,农田粮经饲种植比例从77∶11∶12调整到60∶10∶30,畜牧业有了显著增长,实现了退耕还牧与提高单产同步的目标,开始步入草—畜—肥—粮良性循环的发展阶段。

After four years7 work average yields per mu in 1540 mu farmland had been raised from 50 kilograms to 158 kilograms, average yield production per person from 241 kilogram to 740 kilograms in the test area. In the meantime the proportion of grain,industry, and fodder crops was turned from 77:11:12 to 60:10:30 and the animal husbandry was promoted.
