贵州省畜牧兽医科研所饲料牧草研究室,在肥力相等的两块地上进行了玉米与红三叶套作和玉米单作试验。折合亩产计算,套作的收玉米99.5公斤,红三叶鲜草6161.7公斤;单作的收玉米283.5公斤。套作虽比单作每亩少收玉米184公斤,但多收了6161.7公斤鲜草,折算成粗蛋白质,套作为200.44 Animal Husbandry and Veterinary Research Institute of Guizhou Province feed forage research room, fertile in the same two plots of maize and red clover intercropping and corn single trial. Equivalent to the calculation of mu yield, intercropping received corn 99.5 kg, red clover 6161.7 kg fresh grass; single crop received corn 283.5 kg. Although less than a single set of 184 acres of corn per acre received less, but more income 6161.7 kg of fresh grass, converted into crude protein, set as 200.44
