基于WS和实际耗水量的膜下滴灌

通过田间试验，建立了膜下滴灌棉花CWSI和水汽饱和差VPD的定量关系，确定了棉花各生育阶段CWSI下基线的特定表达形式。对膜下滴灌条件下棉花生长发育、光合动态与根系分布规律以及不同水分处理的耗水量、产量与品质指标进行了观测。对不同水分处理棉花的CWSI进行了定期观测，得到了棉花CWSI与棉花耗水量的关系。     

河南省中低产田地区水资源生产潜

Potential farmer contributions to the design process: Indications from Indonesia

The paper argues that conventional irrigation design processes rely heavily on predetermined design criteria, often without allowing for interactions with farmers and revising of criteria during implementation. Six cases from a tertiary development project in North Sulawesi, Indonesia are described, where farmers altered what had been designed and constructed by contracting and agency engineers. Through field inspections and farmer interviews, the farmers' alternative set of design criteria was elicited to explain why the farmers changed what had been constructed. A total of 27 cases are analyzed to show the relative importance of:

旱田中耕节水灌溉设备的研究

分析了节水灌溉现状；以玉米苗期为研究对象，结合黑龙江省旱作农业实际，提出了一种与中耕相结合的灌溉方式，为采用机械化灌溉方法解决作物苗期干旱问题提供参考。     

Performance indicators for irrigation and drainage

This paper summarises the performance indicators currently used in the Research Program on Irrigation Performance (RPIP).Within this Program field data are measured and collected to quantify andtest about 40 multidisciplinary performance indicators. These indicatorscover water delivery, water use efficiency, maintenance, sustainability ofirrigation, environmental aspects, socio-economics and management. Theindicators now are sufficiently mature to be recommended for use inirrigation and drainage performance assessment.     

滴灌灌水器精密注塑模具设计与开发

以“塑料制品尺寸精度与模具尺寸精度的关系”理论确定模具的精度，进而以精密注塑模具的相关理论和方法进行滴灌灌水器的模具设计，并在型腔、流道、冷却水道的设计中采用严格的计算校核，最后用注射模拟软件分析模具的设计方案，避免了反复的试模与改模，缩短了设计周期，降低了生产成本。     

咸水灌溉下土壤水盐变化的试验研究

2002年在内蒙古河套灌区红卫节水示范园进行了咸水灌溉试验,分析试验结果得出:咸水灌溉下的土壤经过秋浇后含盐量可以降到咸水灌溉前水平。以荷兰Wageningen农业大学等单位开发的土壤水分大气作物系统模拟软件SWAP为工具,应用示范园的土壤、水、盐分试验资料对模型的参数进行了率定和验证,模型模拟结果和田间试验结果符合较好。     

Farmers' perception on self created water management rules in a pioneer scheme: The mula irrigation scheme, India

During the past two decades with farmer participation in irrigation management moving to center stage, the traditional view of having a centralized control over the water resources for better management has changed. Nevertheless, success of irrigation management transfer depend on a whole set of institutional arrangements or the rules-in-use and the willingness of the users to comply and enforce and/or change the rules in the light of changing circumstances. There are many institutional analyses of water sector, much of them touch on law, policy and administration, and characteristics of the users. The present paper is based on the study carried out to examine the institutional arrangements in one of the water users association that was first in the Maharashtra state. It focuses on the institutional arrangements governing water use and distribution and attempts to elicit the perceptions of the members regarding the rules-in-use. The findings reveal that the WUA has been successful in devising and enforcing the rules for water distribution, fee collection and conflict resolution for over a decade. However, current socio-economic developments such as political heterogeneity have required explicit conflict resolution mechanisms. These issues have now become issues demanding immediate attention and may be use of existing courts or legal institutions to help the WUA sustain in future.     

基于物联网Android平台的远程智能节水灌溉系统

针对农业灌溉中的水资源浪费问题和灌溉远程控制问题,对物联网相关技术进行研究,设计了基于物联网Android平台的农业远程智能节水灌溉系统,实现了对多传感器节点(空气温湿度、光照、土壤湿度、电磁阀、变频器等)远程采集和控制,以及对多个控制器节点的远程监测与控制。系统不受时间地域限制,用户可以通过Android移动终端实现对智能节水灌溉系统的监测和控制。系统采用CC2 5 3 0作为无线传感器芯片、OK6 4 1 0作为控制器节点芯片。实测结果验证了该设计的可行性和有效性,可为远程智能节水灌溉提供平台支持,能够满足农业节水灌溉的需要。     

新疆盐碱地长期利用盐水灌溉土壤盐分变化

在地下水位3～5m、壤质土壤条件下,利用盐碱地时用2～5g/L盐化水灌溉,土壤1m剖面均为脱盐状况。灌溉盐化水15年后,1m土壤残留阴离子浓度较小,多点平均为3.709毫克当量/100克土。其中HCO-3相对较多,1m多点平均为0.404毫克当量/100克土。K++Na+浓度很大,1m多点平均为2.492毫克当量/100克土。这时,土壤1m全盐多点平均为0.248%,在灌溉水矿化度不直接危害作物生长时,不影响耕作和作物正常生长。由此可见,盐化水在盐碱地上无排灌溉,是可行的。
