在我国,约有60%的地区水资源匮乏。用珍贵来形容水资源一点也不为过。而这些珍贵的水源每年有70%运用在农业用水中,其中农田灌溉每年达3700-3900亿吨。占农业用水的90%-95%。如何科学地管理农业用水,合理灌溉对节约水资源有着至关重要的作用。本文以近几年来被吉林省地区大面积种植的农作物玉米作为研究对象,通过研究影响玉米精量灌溉的控制因子,为自动控制系统提供所需水分数据,研究精量灌溉自动控制的方式,达到节水、高产的目的。
In our country, about 60% of the region’s water resources are scarce. Use precious to describe water resources is not an exaggeration. 70% of these precious water sources are used in agricultural water each year, of which farmland irrigation amounts to 3700-3900 billion tons annually. 90% -95% of agricultural water. How to manage agricultural water scientifically and reasonably irrigate are crucial to water conservation. In this paper, crop corn planted in large area in Jilin Province in recent years was taken as the research object. By studying the control factors affecting the precision irrigation of corn, the automatic control system was provided with the necessary moisture data to study the automatic control of precision irrigation, Water, high yielding purpose.
