一、引言在农业科学试验中,包括各种农作物的最佳生长环境的创造,为获得农产品产量的最高经济效益的选择,以及微生物学、昆虫学、病理学及植物生理等研究需要的多种特殊环境的实现,都要求用计算机来实现自动控制,才能保证环境的准确性和稳定性,从而得到可靠的观测数据。目前,日本、西德、加拿大及苏联等国已将计算机应用于人工气候室和生长箱上,并作为产品出售。但由于其价格昂贵,需大量外汇,加之工作环境要求严格,不适合我国国
I. Introduction In agricultural science experiments, including the creation of the best growing environment for various kinds of crops, the choice of the highest economic efficiency for obtaining the yield of agricultural products, and the variety of research needs in microbiology, entomology, pathology and plant physiology The realization of special environment, require the computer to realize automatic control, in order to ensure the accuracy and stability of the environment, so as to obtain reliable observation data. Currently, countries such as Japan, West Germany, Canada and the Soviet Union have applied computers to artificial climatic chambers and growth chambers and sold them as products. However, due to its high price, requiring a large amount of foreign exchange, coupled with strict working conditions, is not suitable for our country
