温室环境自动检测系统

温室环境是温室内作物生长的先决条件。目前我国温室环境的管理大部分是靠人工根据经验进行的，从而降低了作物生产的质量，因此温室环境的自动检测和控制是急需解决的课题。文中研究提出的温室自动检测系统，采用了专家系统指导下的实时处理方法，可及时方便地向用户提供技术指导和技术咨询服务，建立了友好的人机界面。     

国内外土壤质地自动分类程序介绍

土壤质地是反映土壤物理特性的一个综合指标,土壤质地命名的自动化将有效提高土壤质地分类工作的效率。本文结合土壤质地自动分类程序研究的现状与特点,着重阐述并讨论了目前较为成熟的TAL、TRANGLE和STAC自动分类计算机程序的设计、功能、使用和实例及其异同与优缺点。土壤质地命名的应用试验表明:TAL和TRANGLE程序在批处理数据量、分类制、图形显示、统计功能等方面存在局限,STAC程序则相对较为完善、方便、实用。     

自动补气阀对卷心菜真空冷却过程的影响

卷心菜采用常规真空冷却工艺时，因其菜体结构紧密，中心与表叶的最大温差可达12．3℃。通过冷却过程分析，提出了增设自动补气阀来减小蔬菜内外温差的方法。结果表明，增设自动补气阀后温差可减小到2.3℃。对于特定食品的真空冷却，设定一个恰当的自动补气阀工作压力范围，可以有效减小各部分的温差。

为了实现对废水污染源企业的实时在线监控,对监测信息进行管理和发布,综合利用自动控制、嵌入式数据采集与传输、分布式计算与数据处理、地理信息系统等技术,研制了山东省废水污染源自动监测监控系统。该系统集全省废水污染源企业自动监测信息的采集、传输和日常处理工作为一体,不仅实现了对废水污染源企业的连续在线监控,并且对监测数据进行深度挖掘与利用,为节能、降耗、减排、总量控制等环境管理工作提供了科学和客观的依据,满足环境管理及相关部门对废水污染源管理的要求。     

自动电位滴定法快速测定脐橙叶片中氯含量

建立了一种基于自动电位滴定技术的脐橙叶片中氯含量的快速检测方法。该法采用稀硝酸浸提脐橙叶片中氯,然后用自动电位滴定法快速测定溶液中氯含量,并考察了方法的测定条件、精密度和准确度。该方法的检出限为0.6249mg/L,加标回收率为94.85%～102.96%,相对标准偏差小于3.0%,故该法适于脐橙叶片中氯含量的快速分析。     

Allocation of feed based on individual dairy cow live weight changes: II: Effect on milk production

Based on individual cow live weight gain, feeding strategies were designed for individual feeding of dairy cows in loose-housing systems, and examined in a four-year production trial including 115 Danish Red (DR), 91 Danish Holstein (DH), and 93 Danish Jersey (DJ). The objective of the present paper was to examine the milk yield obtained in response to three feeding strategies. The interrelationship between feed intake and live weight changes is presented in a companion paper.Cows were stalled in a loose-housing system based on automatic milking, automatic recording of feed intake and automatic weighing of the cows. All cows had 3 kg of individually separately offered concentrate (ISC) in addition to a mixed ration (MR). Cows were either allowed a medium energy MR during whole lactation (strategy MR1) or a high energy MR during early lactation, which was reduced to a low energy MR either early or late (strategy MR2-E and MR2-L). The early and late changes were defined as a live weight gain after live weight minimum at 15 and 35 kg, respectively, for DR/DH and 11 and 25 kg, respectively, for DJ. When MR energy concentration was changed, cows on the MR2 strategies were offered 3 kg per day of extra concentrate. The total allowance of 6 kg ISC was stepwise reduced to 3 kg per day as live weight continued to increase until 50 and 35 kg for DR/DH and DJ, respectively.Compared to feeding the MR1 strategy, the analysis showed that feeding the MR2 strategies did not significantly affect milk yield within primiparous DR and DH or within any DJ, as total lactation feed energy intake within these groups of cows was not significantly affected by the feeding strategy. Results obtained for multiparous DH showed that it is possible to increase milk yield without reducing the milk:feed ratio, when MR2 strategies were applied compared to the MR1 strategy. Feeding high energy rations during early lactation caused a higher peak feed energy intake within multiparous cows of DH and DR, but only multiparous DH obtained higher peak ECM yield in response to higher feed energy intake in early lactation. Across breed the results suggested that cows offered the MR2-E strategy might obtain higher lactation ECM yield compared to cows offered the MR2-L strategy due to a higher ECM yield persistency obtained by cows offered the MR2-E strategy. Results on feed intake and live weight changes presented in a companion paper indicated, that cows offered the MR2 strategies obtained a lower extent of mobilization compared to cows offered the MR1 strategy, and feeding the MR2-E strategy significantly increased duration of the mobilization period, which might have increased MR2-E cows' ability to maintain a high milk production during mid lactation.
