针对国产微灌系统在使用过程中,灌水器易被堵塞的难题和农业生产管理水平不高的现实,打破微灌灌水器流道的截面通常尺寸(一般直径为0.5～1.2毫米)而采用超大流道。以φ4PE塑料小管代替微灌滴头,并辅以田间渗水沟,形成一套以小管出流灌溉为主体的符合实际要求的微灌系统。主要适宜于保护地蔬菜、花卉栽培中应用,在保护地应用该项技术时可配合地膜覆盖,以降低保护地环境湿度。
In view of the fact that the domestic micro-irrigation system is in the process of being used, the problem that the emitter is easy to be blocked and the agricultural production management level is not high, the general size of the cross section of the micro-irrigation emitter channel is broken (generally 0.5 to 1.2 mm in diameter) Runner. The φ4PE plastic tube instead of micro-irrigation dripper, supplemented by field seepage ditches, forming a small tube outflow irrigation as the main line with the actual requirements of the micro-irrigation system. Mainly suitable for the protection of vegetables, flowers and cultivation applications, in the protection of the application of the technology can be covered with plastic film in order to reduce the protection of the environment humidity.
