Design and Implementation of Stud-farm Daily Management System Based on C/S Structure

In order to achieve the computerization and digitization of the daily system of stud-farm, the immunization system technology, racecourse health monitoring technologies and the stud-farm prevention technologies were combined to built the studfarm daily management system. By using Visual Studio 2008 and Microsoft Office Access 2003, an immunization information system was developed based on Client/Server structure and combined with the key immunization link of horses. The system included studfarm immune management and racecourse health monitoring system. The immune management contained immunization information input, the inquiry of immunization information, immunization statistics, immunization-reminding and system management. The racecourse health monitoring system included stud-farm monitoring, horses monitoring and inquiry and statistics of health monitoring. The software realized the analysis and tips of the daily information in stud-farm. The software could record the appropriate data and carry on the statistics. The stud-farm daily management system greatly improved the efficiency of the expanded program about immunization and horses＇ healthy rearing technique.

青海三角城种羊场草场硒的季节变化及其盈缺分析

经过对青海省三角城种羊场夏(6月中旬)、秋(9月中旬)、冬(12月中旬)三季的水、土壤、牧草、绵羊被毛、血液、组织器官及粪中硒的含量进行调查分析,结果表明,三角城种羊场夏季土壤和牧草严重缺硒;绵羊血浆硒浓度全年均属正常;肝硒浓度低于临界水平;粪硒浓度冬季低于0.1mg/kgDM的正常值;被毛硒则在夏秋两季稍高,冬季严重缺乏,仅为0.012 mg/kg,极显著的低于羊毛缺硒值0.079 mg/kg(P<0.01)。

伊犁种马场不同畜牧业生产方式下草地资源利用对比分析

【目的】探讨伊犁种马场在不同畜牧业生产方式下草地资源优化利用格局。【方法】全面了解伊犁种马场草地资源现状的基础上,以草地资源学和生态置换理论为指导,对其变革生产方式前后自然资源、社会经济状况进行深入调查收集,对比分析不同生产方式下研究区草地资源利用状况、经济和社会效益。【结果】变革生产方式后,研究区农、牧业产值都明显增加;农牧民牲畜饲养规模也发生了显著变化,相对于变革前,饲养总量减少24.26%,特别是羊的饲养量减少了38.96%。草地生产力逐步提高,草畜基本平衡;同时,家庭人均纯收入为7 506.46元,相比变革前5 291.88元,增长了41.85%。农牧民传统放牧的观念也得到了极大地改变。【结论】伊犁种马场草地资源的利用及经济、生态效益在暖季放牧、冷季舍饲的放牧方式下明显优于传统的四季游牧。

封育对河曲马场退化沼泽湿地植被恢复的影响

通过对河曲马场不同封育年限的退化沼泽湿地植物群落调查,采用优势度指数、丰富度指数、Shannon-Wiener多样性指数、均匀度指数及其相关性,研究河曲马场退化沼泽湿地植物群落的生物多样性及地上生物量的变化规律。结果表明:(1)地上生物量随着封育年限的延长呈增长趋势,但封育2年达到最大值后开始减少。(2)随着封育年限的延长,优势度指数逐渐降低,丰富度指数几乎没有变化,均匀度指数和Shannon-Wiener多样性指数逐渐增大,即该群落的生物多样性指数逐渐增大。(3)均匀度与Shannon-Wiener多样性指数表现了较高的相关性,这说明物种数在一定范围的前提下,均匀度是增加群落多样性的重要因子。
