在科学技术不断发展的今天,越来越多的先进技术被应用到植物的灌溉当中。玉米膜下滴灌技术就是覆膜种植技术和滴灌方式为一体的玉米灌溉技术,实现了灌溉和施肥一体化。玉米膜下滴灌技术主要是通过控制供水管道系统,将加压后的水和溶解性肥料充分混合,使肥水液体进入输水干管-支管-毛管,最后由毛管上的滴水器均匀、定时、定量滴在需要灌溉的农作体根系,使农作能够充分的吸收水分和肥料。具有操作方便、经济效益高、灌溉效率高以及节能环保等优点,这也是未来植物灌溉技术的主要发展方向。基于此,结合辽宁省凌源市玉米膜下滴灌的应用对其发展前景展开论述。
With the continuous development of science and technology, more and more advanced technologies are applied to the irrigation of plants. The technology of drip irrigation under maize is the technology of maize irrigation, which is a combination of plastic film mulching technology and drip irrigation method, realizing the integration of irrigation and fertilization. Corn drip irrigation technology is mainly through the control of the water supply pipeline system, the pressure of water and dissolved fertilizer fully mixed so that fertilizer and water into the water pipe - branch pipe - capillary, and finally by the capillary drip uniform, regular, Quantitatively drip on the need to irrigate the root system of crops, so that farming can fully absorb water and fertilizer. With convenient operation, high economic efficiency, high irrigation efficiency and energy saving and environmental protection, which is also the future development of plant irrigation technology. Based on this, the development prospects of maize under drip irrigation with corn in Lingyuan City of Liaoning Province were discussed.
