2015年,在新疆阿克苏地区农一师阿拉尔市塔河种业一场原有的棉花膜下滴灌系统基础上,改造成为自动化滴灌工程,并对自动化滴灌棉花灌溉制度和土壤墒情进行了试验研究。以典型的一个轮灌组为例,采用自动化技术监测同时工作的各出地桩(灌水小区)流量、管道压力及其相应灌溉片区里的土壤墒情变化,分析各灌水小区的灌水量与产量的关系。结果表明:灌水量增加到一定程度后,产量随着灌水量增加反而减少,灌溉定额为7 426 m3/hm~2时,产量达到最高值6 567.60 kg/hm~2,可为条件相似地区推广自动化技术和编制灌溉制度提供参考。
In 2015, based on an original cotton film drip irrigation system in Tahe Seed Industry Co., Ltd., Alar City, Aksu Prefecture, Xinjiang, the project was transformed into an automatic drip irrigation project and experimental studies on automatic drip irrigation cotton irrigation system and soil moisture were carried out . Taking a typical irrigation group as an example, the automation technology was used to monitor the flow of the piles (irrigation districts), pipe pressure and the soil moisture in the corresponding irrigated area at the same time, and to analyze the irrigation amount and yield of each irrigated area relationship. The results showed that after the irrigation volume increased to a certain extent, the yield decreased with the increase of irrigation volume. When the irrigation quota was 7 426 m3 / hm ~ 2, the yield reached 6 567.60 kg / hm ~ 2, which could be promoted in similar areas Automation technology and preparation of irrigation system to provide a reference.
