摘要
运用线性规划法设计畜牧业生态系统，研究了陇县跃先村主要饲料作物和家畜的生产效益特征，结果表明，在当地生产条件下，饲料作物生产的效益为：玉米＞苜蓿＞高粱＞大豆＞天然牧草（羊草５５％，草木樨２５％，蒿类２０％）；家畜生产的效益为：奶牛＞奶山羊＞肉牛＞肉羊＞蛋鸡＞猪＞役畜。扩种玉米和苜蓿，减少天然牧草和大豆规模，压缩役畜，稳定猪鸡，发展奶畜、肉牛和肉羊生产，强化系统管理，可使肉、奶、蛋产量分别增加５．５７，１９和１．７倍，羊单位产值增加４．６倍，饲料作物产量达１．
The production benefit characteristics of domestic animals and foragecrops were studied in Yaoxian Villege,Longxian County from 1986 to 1995.The resultsshowed that,under the local conditions, the returned benefits of forage crops of maizeare the greatest followed by alfalfa,sorgo,bean,and wild grass(50% Aneurolepidiumchinense,25% Melilotus Adans and 20% Artemisia L.),and the benefits from animalproduction of milk cow greatest followed by milk goat,meat animals,egghen,swine,andwork animals at the lowest.Thus,the yields of meat,milk and egg would be increasedby 5.57,19 and 1.7 times,and forage yield and sheep unit by 15,000.0 kg/hm￣2 and 4.6times respectively,if the planting areas of maize and alfalfa can be increased and thedairy animals,meat cattle and goat well developed,and systematic management en-forced.
