“两粮一肥耕作制”的基本种植方式是:春小麦和玉米采用带状型的套种,小麦收后复种箭舌豌豆等绿肥作物,第二年更换小麦、玉米播种位置,小麦收后仍复种绿肥,两年后改种水稻(稻旱轮作田)或其它作物。1984年灌区推广此法已达40多万亩,生产实践证明,这种耕作法一般亩产粮食可达1100～1200斤左右,绿肥鲜草3000斤左 The basic planting methods of “Liang Liang and a fat farming system” are: banded spring wheat and corn, green wheat crops such as reed-tufted peas after the wheat harvest, the replacement of wheat and maize sowing position in the next year, Green manure, two years later re-rice (rice dry round crop) or other crops. In 1984, the method of popularizing this method has reached more than 400,000 mu. Production practice has proved that this farming method generally yields about 1100-1200 kg of mu per mu, about 3000 kg of fresh green grass
