| 1. | Analysis of water flow performance and irrigation efficiency of boder irragation under straw mulch 秸秆覆盖畦田灌溉水流特性及灌水质量分析 |
| 2. | Irrigation efficiency has been identified as a development need by imar and imau officials 内蒙古和内蒙古农业大学的领导们认为节水灌溉也是内蒙古农业大发展所需要的。 |
| 3. | A reservoir ' s flood control and dispatch are directly related to the safety in flood control and its irrigation efficiency 摘要水库的防洪调度直接关系到防洪安全及兴利效益的发挥。 |
| 4. | Nht irrigation specialists provide hardware and management techniques and irrigation efficiency training program to help irrigators save water and energy , reduce power bills , and optimize crop yields Nht的灌溉专家提供硬件管理技术和有效灌溉培训项目,来帮助灌溉者节约水电,减少电费以及使农作物产量最优。 |
| 5. | Since agriculture accounts for nearly 70 percent of the world ' s fresh water withdrawn from rivers , lakes , and underground aquifers for human use , the greatest potential for conservation lies with increasing irrigation efficiency 自从农业的估计世界上的新鲜水有近70 %将从河川,湖泊及地下水供人使用起,水保育的强大潜力是增加有效灌溉。 |
| 6. | And then , the irrigation performance including irrigation efficiency , application efficiency and distribution uniformity were evaluated by using infiltration parameters and soil parameters . the results indicate surge furrow irrigation is suitable to hilly mountain areas 利用入渗参数以及田间基本参数,对灌水质量:储水效率e _ n 、灌水效率e _ a和灌水均匀度e _ d进行了评价,评价结果表明在丘陵山区适宜进行波涌灌溉。 |
| 7. | It shows that the traditional irrigation schedule should be modified . to evaluate exist field irrigation performance , irrigation tests were performed and simulation model , srfr , was used . evaluated results of irrigation efficiency are 0 . 68 and 0 . 52 in huimin and wudi respectively 通过对灌溉试验实测资料的分析,由田间灌溉模拟模型srfr模拟并确定灌区田间土壤入渗参数k 、 、 n ,然后综合求出惠民田间灌溉效率为0 . 68 ,无棣为0 . 52 。 |
| 8. | In the view of regional water balance and cropping irrigation efficiency increase , optimized model for the mid - long term cropping was proposed . practicing these pattern can guarantee water resources balance , satisfy the requirement of production , economic increase and ecological efficiency for agriculture 该方案基本可以实现顺义区种植业水资源的平衡利用,满足社会对农业生产的需求,并使农业经济效益和养殖业生产得到最大可能的保证。 |
| 9. | / based on the trends of present cropping development and irrigation efficiency increase in the region , water supply can meet irrigation by 89 % in 2010 , 75 % in 2020 and 70 % in 2030 to crop ' s water requirement under normal condition . water supply can meet irrigation by 100 % in 2010 , 88 % in 2020 and 83 % in 2030 to 85 % of crop ' s water requirement under normal condition . the situation of water shortage in the region is more austere in dry year 3 )按目前种植业发展趋势并考虑到灌溉效率的提高,平水年在100充足灌溉方式下, 2010年、 2020年和2030年可供水量对灌溉的满足率分别为89 、 75和70 ;在85亏缺灌溉方式下, 2010年供水可以满足需要, 2020年和2030年供水量对灌溉的满足率为88和83 ;干旱年度的灌溉满足率更低,形势更为严峻。 |
