灌溉效率 meaning in English
efficiency of irrigation
irrigation efficiency
Examples
- The development of such plants could help farmers to develop more efficient irrigation of crops
报道说，这一技术将有助于农民提高对庄稼的灌溉效率。 - So the potential water - savings is very large , especially in wudi county . the irrigation scheduling optimization is based on the simulation with isareg model
说明该区现状灌溉效率不高，用水浪费较多，同时也表明了该区尤其是无棣节水潜力很大。 - 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 。 - / 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。 - Aiming at the present low efficiency of well irrigation works and through pumping tests and theoretical analysis , the paper derives a method for calculating the optimum water yield , the best lifting distance and economic pipe diameter of low pressure pipe delivery system of irrigated area by wells , increasing the efficiency of motor - pumped wells
针对目前井灌工程效率低下的问题，通过抽水试验，经过理论分析，推导出了井灌低压管道输水灌溉系统的最优出水量、最佳扬程和经济管径计算方法，从而可提高机井灌溉效率。
