我国北方地区正在大规模发展节水灌溉,各地结合自身的特点采用了不同的节水灌溉工程技术模式。这些节水灌溉工程技术模式,不但在北方乃至全国都有普遍的推广应用价值。为了使这些模式更加完善,针对其中几种有代表性模式的一些技术问题进行探讨。1城郊设施农业节水高效工程技术模式设施农业栽培也称保护地栽培,是利用日光温室、塑料棚等保护设施,人为地创造适于作物生长发育的环境条件。从而
In northern China, large-scale development of water-saving irrigation is being carried out and different modes of water-saving irrigation engineering have been adopted in all parts of the country in light of their own characteristics. These water-saving irrigation engineering technology model, not only in the North and the country have universal value of the promotion. In order to make these models more perfect, we discuss some technical problems in several typical modes. 1 suburban facilities Agricultural water-saving and efficient engineering and technical mode facilities Agricultural cultivation, also known as protected cultivation, is the use of solar greenhouse, plastic shed and other protective facilities, artificially create suitable for crop growth and development of environmental conditions. thereby
