为了提高灌溉的水分利用效率和经济效益,结合当地农民种植玉米常见的灌溉方式,对畦灌、膜上灌和膜下滴灌三种灌溉方式下的水分利用效率和经济效益进行了试验研究。试验结果表明:制种玉米膜下滴灌的水分利用效率最高,较畦灌提高了40.7%,较膜上灌提高了46%,且畦灌的经济效益最高。
In order to improve the water use efficiency and economic benefits of irrigation, the water use efficiency and economic efficiency under three irrigation modes of irrigation, membrane irrigation and drip irrigation were experimentally studied in combination with the common irrigation methods of local farmers planting corn. The results showed that the water use efficiency of seedling under drip irrigation was the highest, which was 40.7% higher than that of irrigation, 46% higher than that of irrigation, and the economic benefit of irrigation was the highest.
