| 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1.5t/hm2。 |

| Abstract: |
| The production benefit charaeteristies of domestic animals and forage
crops were studied in Yaoxian Villege,Longxia County from 1986 to 1995.The results
showed that,under the local conditions,the returned benefits of forage crops of maize
are the greatest followed by alfalfa,sorgo,bean,and wildgrass (50% Aneurolepidium chinense,25％ Melilotus Adans and 20% Arremisia L.),and the benefits from animal
produetion of milk cow greatest followed by milk goat,meat animals,egghen,swine,and
work animals at the lowest.Thus,the yields of meat,milk and egg would be increased
by 5.57,19 and 1.7 times,and forage yield and sheep unit by 15,000.0 kg/hm2,and 4.6
times respeetively,if the planting areas of maize and alfalfa can be inereased and the
dairy animals,meat cattle and goat well developed,and systematic management enforeed. |
