通过田间试验得出 :冬小麦后复种经济作物效益显著。冬麦后复种糯玉米亩纯收入最高为 813.3元 ;其次为复种饲草籽粒苋 6 32 .7元 ;以后依次为复种鲜毛豆 5 2 5 .2元、复种饲用玉米中原单 32号 4 71.8元、复种饲用油菜 4 0 0 .2元、复种油葵 333.1元 ,且效益均高于套种玉米。复种收籽粒小黄豆亩纯收入 186 .9元 ,复种糜子 10 1.4元 ,均低于套种玉米效益 ,故今后应视市场价酌情推广。
Through field experiments, it is concluded that the economic benefits of multiple cropping of cash crops after winter wheat are significant. After winter wheat, the net income per mu of waxy corn was 813.3 yuan, followed by that of compound seeds of forage grasses was 632.7 yuan, followed by 5252 yuan of compound soybean, 3541 yuan Yuan, polyculture fodder rape 40.02 yuan, oil sunflower 333.1 yuan, and the benefits are higher than the intercropping corn. Reciprocation seeds received small acres of wheat net income of 186.9 yuan, 10.9 yuan multivariate, are lower than the benefits of intercropping corn, so the future should be regarded as market price promotion as appropriate.
