河套灌区灌溉制度研究

根据河套灌区的气象、土壤、灌水等资料,利用ISAREG模型模拟了4种主要作物充分灌溉和非充分灌溉2种灌溉制度方案。根据模型的优化模拟结果分析,在作物产量比率仅略有下降的情况下,作物实施非充分灌溉将减少灌水次数和灌溉定额(平均下降45 mm),建议灌区把作物实施非充分灌溉作为一种节水措施之一。     

地下滴灌棉花栽培试验与技术研究

根据新疆兵团农五师九十团8hm^2地下滴灌棉花栽培、灌溉和施肥等方面的试验研究，地下滴灌与地面滴灌比较，无论投入产出和作物的长势，地下滴灌都比地面滴灌优越。地下滴灌比地面滴灌工程设备、材料费低0．15297万元／hm^2，降低年运行费用841．8元／hm^2。     

水稻"淹灌-露田"灌溉模式试验研究

在总结水稻传统淹水灌溉方式及现行节水灌溉方式的基础上，研究提出了水稻“淹灌－露田”灌溉模式，该模式具有减少灌水次数，减轻灌溉管理的劳动强度，减少斗农渠的输水时间从而提高输水效率，并可提高降雨利用率等优点，介绍了该灌溉模式的基本依据、技术要点及在湖北省宜昌市东风渠管理处灌溉试验站的试验情况，并根据2000－2001年的试验资料，对该灌溉模式的灌溉效果进行了分析。     

节水灌溉对水稻钾素营养的影响

研究了节水灌溉条件下、不同施肥制度水稻植树对钾的吸收状况。结果表明：灌溉方式和施肥制度对水稻钾的吸收状况均不会造成极显著的影响。节水灌溉能显著提高水稻植株含钾量。     

棉花膜下滴灌灌溉制度试验研究

以田间试验为基础对棉花膜下滴灌的灌溉制度及其各因素的特点进行了分析研究。膜下滴灌技术采用局部灌水，男间地面蒸发量很小，另外，该技术为浅灌且可控性强，使灌水深度与棉花根系吸水深度相一致，避免深层渗漏，极大地提高了田间水分利用率。     

文丘里差压式喷灌施肥装置的性能研究

本文主要介绍100PS－1型文丘里差压式施肥装置的工作原理、水力学性能、施肥罐内肥料浓度的变化规律及施肥均匀度的试验数据。通过对试验结果的研究分析,我们认为采用这种形式施肥装置是完全符合喷灌系统对施肥的要求的。     

The quality of service provided by the irrigation department to the users associations, Tunuyan System, Mendoza, Argentina

The quality of service provided by the provincial Irrigation Department (DGI) to the Water Users Associations (UA), and subsequently by the UA's to the related water users, is based on the provincial water law. The intended volume of water being delivered per considered period further depends on the water availability and on the (crop irrigation) water requirements. The Service Level (SL) compares the intended water supply with the water supply that would be required to supply the entire irrigable area with sufficient water. As soon as the intended water delivery pattern is set, the measured actual delivery can be assessed against the intention. Several performance indicators are used in this context. Based on the assessment of the Water Delivery Performance Ratio and the Overall Consumed Ratio recommendations are made on changes which can be made to improve water use and reduce problems of waterlogging.     

依靠农民全面开展节水灌溉

缺水是世界普遍现象，节水是长期战略措施。开发农业节水，一方面要改善灌溉系统的基础设施，推广节水新技术，另一方面应应该吸收农民参与灌溉管理，充分发挥农民的积极性。农民参与灌溉管理是必然的趋势，也是农业节水最有效的措施之一。     

Spreadsheets for water management — a case study from the Brantas Delta,East Java

The use of commercially available spreadsheet programs for scheduling of water supplies for large scale irrigation networks is a relatively new phenomenom. The paper describes the development and application of such a program for a 30 000 ha irrigation scheme in the Brantas Delta, East Java. The program has been in use for day-to-day scheduling of main system supplies since April 1986, during which time refinements and adjustments have been necessary to formulate a working package. The paper draws conclusions regarding the value of the program for improving water management.     

垄膜沟种涌泉灌溉技术要素的试验研究

在垄膜沟种农田进行了涌泉灌灌水试验，通过对水流推进过程观测，分析了田面水流运动特性，研究了沟宽对田间灌水均匀度的影响，并对垄膜沟种涌泉灌溉技术要素进行了探讨。结果表明，涌泉灌田面水流推进曲线可用幂函数表示。随着沟宽的增大，灌水均匀度呈下降趋势。从灌水质量和管网成本两方面综合考虑，试验条件下灌水技术要素的入沟流量、沟宽和灌水器间距分别以80～100L/h、20-30cm和4～5m为宜。
