黑豆豆芽工厂化生产关键技术研究

利用黑龙江黑豆、吉林黑豆、上海黑豆3个黑豆品种进行工厂化生产的最佳品种和孵化环境条件试验。结果表明，黑龙江黑豆最适合工厂化生产，其生产最佳孵化环境为：孵化车间采用淋水间隔3.5 h、温度控制在23~25℃、湿度保持在75%以上，发芽后84 h 采收最适宜。     

Research Progress on Influence Factors of Mutton Quality

Meat quality means the characteristics such as appearance is related to palatability in fresh meat or manufactured meat, it includes meat color, meat structure, hardness, marbling, water holding capacity and so on.The physical characteristics of mutton quality determines the consumer acceptability of meat and there is a close relationship between chemical composition of mutton quality and nutrient substance.With the improvement of living standards, consumers are increasingly high demand for mutton.From quantitative to qualitative change, we need to continuously improve mutton quality.At present, the production of high quality animal products has become a hot topic.This paper is a summary of the effects of breed, gender, age, environment and feed nutrition on mutton quality, and aims to provide a scientific basis for improving of mutton quality with nutritional regulation measures.     

陕西百年农业科技发展研究

笔者回顾了陕西百年来不同时期农业科技发展的历史背景与社会环境,分析了陕西农业科技发展的动因与本质、范围与对象、社会需求等内在属性特征;总结了陕西农业科技发展的主要成效,即构建了农业科研技术服务体系、培育推广了技术良种方法、发展了农业产业、形成了农业科技发展的政策人才环境、改变了农业传统观念与生产方式;归纳凝练出陕西农业科技发展的经验启示,即农业科技发展是解决农业诸多矛盾的必然要求、实现农业现代化的有效途径、构建农业安全的重要举措,同时农业科技发展必须以国家需要、人民需求为根本出发点。指出陕西农业科技发展中成果转化率不高、体制机制僵化、省级支持不够、基层人员结构不合理等问题,提出通过“科研面向需求”、设立省级基金、开展农技有偿服务、扩大农技部门人事权限、发挥各类市场主体作用来解决问题,推动全省农业科技持续稳步发展。     

不同蔟具及蔟中环境对彩色茧品种秋丰×黄3茧丝质量的影响

通过不同蔟具及蔟中环境对彩色茧品种秋丰×黄3茧丝质影响的分析,我们得出：在自然通风或封闭环境中,用方格蔟上蔟蚕茧的一茧丝长、解舒长、解舒率、净度和清洁度要比用蜈蚣蔟好,其中解舒率分别提高了6.6%、5%;用方格蔟或蜈蚣蔟上蔟,在自然通风的蔟中环境下所得到的蚕茧茧丝质量比在封闭环境下高,解舒率更是分别提高了11.4%、9...

The Relationship Between Vegetation Characteristics and Altitudes in Transitional Permafrost Zone in Xidatan,Qinghai-Tibetan Plateau

Many studies showed that permafrost has profound influence on alpine ecosystem. However, former researches were mainly focused on typical points by temporal scales. There were few studies about the correlation between vegetation characteristics and different altitudes covering a large region in spatial pattern, especially in transitional permafrost(TP). There were continuous permafrost(CP) discontinuous permafrost(DCP) and seasonal frozen ground(SFG) in this study region. The types of permafrost changed from SFG to DCP, and finally become CP as the altitudes of Xidatan increase. In this paper, 112 845 points interpreted by HJ1-B(environment and disaster monitoring and prediction small satellite constellation), vegetation investigation points, thawing layer thickness research sites, ground temperature and water content observation plots were used to examine the spatial pattern of vegetation which were located in different altitudes in Xidatan, a typical TP region, in Qinghai-Tibetan Plateau. Vegetation characteristics, soil moisture content(SMC) and thaw depths were collected in 15 August to 25 August2012. Characteristics of vegetation were mainly represented by fractional vegetation cover(FVC) derived from the normalized difference vegetation index(NDVI), as well as above ground biomass(AGB). In this paper, we analyzed that the distinction of vegetation characteristics in each range through statistics data. These ranges were divided by varied altitudes. For examples, the ranges were divided into 50 m or 100 m. In this study we use a large area plots method to further discuss the relationship between the features of vegetation and the different regions of permafrost based on altitudes shifts in Xidatan. A diagram described the vegetation characteristics variability with rising altitudes in transitional permafrost region was drawn in this paper. Our results illustrated the FVCs first increased in SFG region and then decreased in DCP zone slowly, and in CP region FVCs soared then dropped dramatically. With the altitudes increased, the curve of FVCs indicated a parabolic distribution except a little difference in the first 200 m range.
