我国是一个农业大国,灌溉的好坏对作物的生长起决定性作用,近年来由于全球气候变暖,水资源愈发紧缺,有的地区甚至出现旱情,作物生长迫切需要水资源,因此节水灌溉技术的使用迫在眉睫。基于此,通过对节水灌溉技术在大田作物上的应用现状和发展进行论述,综合分析得出节水灌溉的技术要求,最后对节水灌溉的意义进行说明,以缓解水资源紧缺的现状,提高作物的产量,并推动我国农业发展,推进我国农业现代化进程。
China is a big agricultural country. The quality of irrigation plays a decisive role in the growth of crops. In recent years, due to the global warming, water resources are in short supply, and some areas even have drought. Crops are in urgent need of water resources, so water-saving irrigation The use of technology is imminent. Based on this, the present situation and development of water-saving irrigation technology on field crops are discussed, the technical requirements of water-saving irrigation are concluded through analysis. Finally, the significance of water-saving irrigation is illustrated in order to alleviate the current situation of water shortage, Improve crop production, promote the development of agriculture in our country and promote the process of agricultural modernization in our country.
