当今之农业是大力发展环境设施,人工控制自然环境与动植物的生长条件,采用先进的系统工程结构从事不受外界干扰、不受季节影响的室内、高效综合生产。它的主要手段是建造各种各样的温室。初级、简易的就是塑料大棚及其配套使用的各种机具、调温、通风等设施。我国在这方面虽然起步较晚,但发展很快,特别近几年尤为迅速。为推进普及这一技术,搞好安装、使用、
Today’s agriculture is to vigorously develop environmental facilities, artificial control of the natural environment and the growth of animals and plants, the use of advanced systems engineering structure engaged in outside interference, not seasonally indoor and efficient integrated production. Its main approach is to build a wide variety of greenhouses. Junior, simple is the plastic greenhouse and its supporting the use of a variety of equipment, temperature control, ventilation and other facilities. Although our country started late in this area, it has developed rapidly, especially in recent years. To promote the popularity of this technology, improve the installation, use,
