Irrigation regime for corn production with drip irrigation and plastic mulching in Hetao i rrigation region
摘要
Abstract
In order to propose a high-yielding and water-saving irrigation regime for corn production with drip irriga-tion and plastic mulching in Hetao irrigation region ,two years of field experiment was conducted .Crop evaportranspi-ration for corn was measured ,and crop water productivity was estimated using the Jensen model .Results showed that corn was tolerant to water stress at seeding stage when water shortage had less effect on corn growth .By contrast ,corn plant was sensitive at stages of jointing to tasseling ,tasseling to flowering and flowering to filling .Irrigation amount of 275~325 mm resulted in higher grain yield ,with the distribution of irrigation being 20~40 ,40~60 ,115 and 80 mm at the stages of seedling to jointing ,jointing to tasseling ,tasseling to flowering ,and flowering to filling ,respectively , Compared with the usual surface irrigation ,irrigation water saved ranged from 2 546 .25 to 3 296 .25 mm per hectare .关键词
