    健康问题日益引人注目的当今,水果保健成为全民关注的保健方式之一蓝莓作为健康保健功效水果,富含的营养成分和保健功能得到了广泛的认同和赞许。在产业需求急剧增长的现在,其生存条件和产量成为了制约其满足市场需求的主要因素。随着设施农业的发展,反季节种植的进步,为蓝莓的生产种植提供了基础;而现如今节能设备的广泛运用,气候资源的逐步完善,为设施农业的节能降耗提供了基础,同时也对蓝莓生产种植的环境模式提出了迫切要求。目前,设施农业方面蓝莓种植的工艺值得商榷,对于调节蓝莓环境气候增加产量的研究还比较少。而且,由于设施农业的能源消耗率,使得利用设施农业进行蓝莓集中栽培收获的能源耗量成为难点。气象数据的统计方面,对于设施农业用参数也需要补充完备。

    针对以上问题,结合节能模式的多样性,本文研究了蓝莓生长过程中影响极大的气象因素,通过选择了设备节能的模式,分析典型的新风空调系统,通过对其空气处理方式及空气变化过程进行分析,找出影响其运行的主要气象因子,并结合蓝莓与设施农业气象参数的关系提出了湿系数的物理量作为影响节能指标之一。在设施农业气象参数方面,整合节能设备相关的气象参数,通过对比分析选取了适合本项研究的气象统计数据集作为数据源,在累积参数处理过程中,通过对设备全年运行调节确定了对于焓时数等累积时间的基准点通过相关选定设备空气处理过程的焓湿图确定了累加参数的差值计算点。在节能指标研究当中,研究内容采集分析了全国200多个城市的干球温度、平均空气湿度、焓的累积参数,采用数学方法中的模糊聚类对全国范围地区进行节能模式的分区。

    本项研究为蓝莓生长设施环境提供了几个重要的气象参数的处理方法,最后得到蓝莓生长设施环境分区同时配合节能模式,为设备选择合理供给了依据,减少了各部分的能耗,达到因地制宜的目的

    ABSTRACT

     

    Health problems are becoming increasingly conspicuous nowadays, fruit health has become one of the universal concern of health care, health care efficacy as the blueberry fruit, it is rich in nutrition and health care function has been widely acceptance and praise. With the rapid growth of industrial demand, the living conditions and production have become the main factors which restrict the market demand. With the development of agricultural facilities, anti season planting progress, provide the basis for the production of blueberry planting; and the extensive use of energy-efficient equipment now, climate resources gradually perfect, provides the basis for energy saving of agricultural facilities and made an urgent request but also on the blueberry production environment planting mode. At present, the technology of blueberry cultivation in facility agriculture is questionable, and the research on the regulation of blueberry climate and environment to increase yield is still relatively small. Moreover, due to the energy consumption rate of agricultural facilities, making the use of protected agriculture to focus on the cultivation of blueberry harvesting energy consumption becomes difficult. Statistics of meteorological data, also need to complete the parameters for the installation of agricultural.

    To solve the above problems, combined with the diversity of energy-saving mode, studied the influence of meteorological factors of blueberry greatly during the growth process by choosing such models, analysis of typical air conditioning system, through the way of dealing with the air and air change process analysis, find out the main meteorological factors affecting the operation of the relationship, and combination of blueberry and facility agriculture meteorological parameters proposed a physical quantity of temperature and humidity coefficient "as one of the effects of energy saving index. In the aspect of facility agriculture meteorological parameters, meteorological parameters and integration of energy saving equipment, through the comparative analysis of selected meteorological statistical data for the study of the collection as a data source, the cumulative parameters in the treatment process, through adjusting the air conditioning system operation to determine the reference point for the number of enthalpy of accumulated time and through the fresh air the air handling process equipment to determine the difference of enthalpy cumulative parameter calculation point. In the study of energy saving index, research content acquisition and analysis the cumulative parameters of dry bulb temperature, average air humidity and enthalpy of the country's more than and 200 City, combined with the mathematical methods of fuzzy clustering is used to partition the national energy saving mode.

    Methods this study provides several important meteorological parameters for blueberry growth facility environment, finally get the blueberry growth environment facilities, combined with energy-saving mode, provide the basis for reasonable selection of equipment, to reduce the energy consumption of each part.
