- Title:
- An Experimental Study on Rainfed Agriculture Technical System of Increasing Grain Output in Semiarid Loess Hilly Region
- 摘要:
- 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.
- Abstract:
- The some farmland renounced to planting grasses and at meantime increased productivity,the key was to establish an farming and afforest conbination system and input energy as a driving force.Four-year results as follows:29% farmland renounced to planting grasses.Cropping system carried out and at same time total grain output,biomass,each person had grain and oil as well as ecnomic income increased 1.17,86.9%,1.11 and 3 and 3.38 times respectively than before.At meantime the organic material and total organic fertilizer in soil increased 193% and 104%,and chemical fertilizers decreased 55.3%,and also,agri-ecosystem began to change a better cycle.
