滴灌灌溉制度对樱桃西红柿产量及灌溉水分生产率的影响

摘要

Compared with furrow irrigation , the influence of different irrigation systems on cherry tomatoes yield and water productivity was studied under drip irrigation conditions . The results show that under the conditions of saline sandy soil reclamation , by controlling soil moisture and salinity effectively , the most economical irrigation system ( high frequency irrigation+Salt leaching ) can achieve savings of irrigation water by 21.5% , increasing production by 3.0% , improving irrigation water productivity by 31.2% , with the highest irrigation benefit and efficiency .%以沟灌为对照，研究滴灌条件下不同灌溉制度对樱桃西红柿产量和灌溉水分生产率的影响。结果表明，在围垦盐化砂质土壤条件下，各试验处理中经济效益最优的灌溉制度（高频灌溉＋盐分淋洗）通过有效控制土壤含水率和盐分，相比对照可实现节约灌溉用水21.5％，增加产量3.0％，提高灌溉水分生产率31.2％，灌溉效益和效率相对最高。
