摘要:
 温室大棚可以帮助瓜果蔬菜在其非时令季节提供生长环境和增加产量。由于季节对于植物自然生长的不适宜性，因此作物对于温室大棚的生长环境要求就要精确得多。通过搭建Zigbee无线传感器网络有效地对温室草莓生长的空气湿度、土壤湿度、土壤盐碱度、温度、CO2浓度及光照六个指标进行了长期的数据采集，并尝试通过主成分分析的方法来分析影响温室草莓育苗期生长的关键因素。通过对育苗期温室草莓的上述六个环境指标进行主成分分析，分析所得的三个主分量的贡献率分别为44.57%、29.00%和15.83%，累计贡献率可达到89.40%。因此，可以用这三个主分量代替原有的六个单项指标反映原指标的绝大部分信息对温室草莓生长环境进行研究，且使得各综合指标所代表的信息不再重叠。有助于实现温室种植的再生产以及高效的、精准化的管理。
Abstract:
 Greenhouses can provide fruits and vegetables with growth environment in its non-growth seasons and help increase their pro-duction. The greenhouses environment requirements are more accurate because of the inappropriate season for plants growth naturally. There mainly involves six indicators of greenhouse strawberry growth environment including air humidity,soil moisture,alkalinity,tem-perature,CO2 ,and light-intensity. Relative data is collected by the wireless sensor network for a long time,and principal component anal-ysis is applied to analyze the key factors influencing the greenhouse crop growth during the seeding period of green strawberry. The analy-sis shows that there are three principal components and their contribution rate are 44. 57%,29. 00% and 15. 83% respectively. The cumu-lative contribution rate can reach 89. 40% and therefore these three principal components can be used to replace the original six indicators to reflect the original greenhouse strawberry growth environment information and to represent the information no longer overlap,which is very important to the reproduction of same plants and can enable them to improve the efficiency and accuracy of greenhouse cultivation management greatly.
