南疆自动化滴灌棉花灌溉制度的研究
|
摘要
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,the former cotton mulched drip irrigation system in the Tahe farmland of Aral city of 1st Agricultural Diversion in Aksu of Xinjiang was reconstructed to an automatic drip irrigation system. The experimental study on automatic irrigation schedule and soil moisture was conducted. In this paper,taking a typical alternate irrigation unit as example,the automatic technology is used to monitor the flow rate of out-ground piles working at the same time,pipeline pressure and the soil moisture change of the irrigation area to analyze the relation between the yield and irrigation amount of each irrigation unit. The results show that: the yield decreases with the increase of irrigation amount when irrigation amount has increased to a certain degree; the yield reaches the highest value of 6 567. 60 kg when irrigation quota is 7 426m~3/ hm~2. The results can provide reference for extending the automation technology and deciding irrigation schedule in irrigation districts with similar conditions.
