From attaching great importance to the construction of rural ecological civilization to the production and living mode of ecologically livable agriculture in rural areas, China’s agricultural ecological economy has made great progress. At this stage, China’s economy was in the period of characteristic construction. As an important part of China’s characteristic economy,it was very important to re-examine and position the agricultural economy based on the perspective of ecological environment construction how to give full play to its value function. Based on the theoretical perspective of coordinated development, this paper analyzes the content, characteristics and mechanism of the coordinated development of agricultural ecological environment and agricultural economy, and deeply analyzes the obstacles in the process of their coordination in order to build a more perfect development path, aiming to promote the green sustainable development of agricultural ecological economy.
The research aimed to evaluate the immune effects and the quality of clinical application of mass highly-pathogenic avian influenza vaccines at present.Blood samples were collected from 127 chicken farms,22 duck farms,2 goose farms and 1 pigeon farm by wing vein method.H5-type highly pathogenic avian influenza antibodies were detected by hemagglutination inhibition test and their immune effects were analyzed.The immune of 5 chicken farms were not eligible and 8 duck farms(being mainly meat-duck farms) were not eligible.2 goose farms and 1 pigeon farm were all eligible.The qualification rate of antibody was 88.05% and the qualified immunity farm reached 91.40%.The optimum first-immune time of chickling should be about 2 weeks.The protective efficacy of poultry after immunity inoculation for 2 times was higher and the effective stage of immunity reached 4～6 months.
国民经济建设与发展的经济基础便是农业,我国作为一个农业大国除了少数年份为调剂品种而有进口外每年需要的粮食、肉类、蔬菜、水果等等都是来自本国的农业。农业的发展需要依靠大自然,需要水分、光照、温度等条件,本身就具有一定的脆弱性,需要依靠各种农业生产技术来维护农业的稳定发展。其中不可或缺的一个环节就是灌溉,因为降水、水利等条件的影响,不同地区的农田水分状况也不同,要想加以调节从而提高农田抵御天灾的能力,农田水利应用而生。从古至今,农业的发展离不开水利工程,可以说农田水利事业的兴衰是影响农业发展成果的一个重要的因素。随着时代的发展以及各种客观条件的改变,比如说水资源愈来愈稀缺,很多农田水利灌溉的质量有所下降,本文将对提高农田水利灌溉质量作出分析并给出适当的建议,希望可以为相关工作人员提供有益的借鉴。
