该实验以退耕种草和提高农田生产力同步,建立农牧结合制为核心,以输入能量为动力,经过4年实践获得预想结果:在退耕农田29%种草,实行草田轮作的同时,农田粮食总产增长1.17倍,生物学总产量增长86.9%;人均粮食和油料分别增长1.11倍和3倍;人均农田收入较实验前增长3.38倍;土壤中残留有机物总量增长193%,有机肥料总量增长104%,化肥用量减少55.3%,农田生态开始向良性循环转变. In this experiment, the grassroots cropland was planted and the productivity of farmland was increased simultaneously. With the establishment of a combination of farming and animal husbandry as the core, input energy was the driving force. After 4 years of practice, the expected result was obtained: 29% The total output increased 1.17 times and the biological total output increased 86.9%; the per capita grain and oilseed increased 1.11 times and 3 times respectively; the per capita farmland income increased 3.38 times than that before the experiment; the total amount of residual organic matter in soil increased by 193% An increase of 104%, a decrease of 55.3% of the amount of chemical fertilizer, farmland ecology began to a virtuous circle of change.
