摘　　要：为研究宁夏部分日光温室主打果树的需冷量,进而研发预警装置,计算不同环境果树需冷量的累积值并提示相应环境管理措施。本文对宁夏设施8个葡萄品种和3个桃树主栽品种采用水浸枝条法以及温度观测,借助犹他模型(Utah model)对葡萄、桃品种需冷量及日光温室内有效低温累积量进行测算。结果表明,桃品种春雪、中油5号的需冷量为826 C.U.左右,中油4号的需冷量为942 C.U.左右;葡萄品种红地球、奥古斯特、无核早红的需冷量为930 C.U.左右,美人指、魏可、香妃、早黑宝、奥地亚无核的需冷量为798 C.U.左右。在上述研究的基础上,设计开发了基于Arduino单片机,具有无线集群采集功能的日光温室环境因子采集和数据分析预警装置,以科学指导设施果树在不同阶段的环境管理。To study the chilling requirement of main fruit trees in sunlight greenhouse in Ningxia,the warning device was studied to calculate the cumulative value of chilling requirement of fruit trees under different environments,and the environmental management measures were appropriated promptly. In this paper,using the method of flooding and temperature observations on eight grape varieties and three branches of peach cultivars in Ningxia,and their chilling requirement and effective cryogenic accumulation with the Utah model were studied. The results showed that： the chilling requirements of two varieties of peach‘Chunxue＇and‘Zhongyoutao No. 5＇were 826 C. U.,and the chilling requirement of‘Zhongyoutao No. 4＇was 942 C. U.. The chilling requirements of grape varieties ‘Hongdiqiu＇,‘Aogusite＇,‘Wuhuzaohong＇were 930 C. U.,while the chilling requirements of‘Meirenzhi＇,‘Weike＇,‘Xiangfei＇,‘Zaoheibao＇,‘Aodiyawuhe＇were 798 C.U.. Based on study above,the warning device of sunlight greenhouse acquisition and data analysis of environment factors,which was detected by Arduino single chip microcomputer with a wireless cluster collection,was developed to scientifically guide the facility environmental management of fruit tree at different stages.
