不同灌溉量对春小麦生长及产量构成的影响
Effects of different irrigation treatment on growth and yield constituent of spring wheat
摘要
Abstract
To supply scientific evidences of saving water, a study was made on effects of different irrigation quota on the growth and yield of spring wheat in field conditions in arid and semiarid regions. The results sh owed that the growth and yield of spring wheat was unchanged under irrigation qu ota of 4 286 m3/hm2 (209 m3/hm2 less than comparison treatment). Though irrigation quota of 3 670 m3/hm2 (825 m3/hm2 less than comparison treatm ent) influenced the growth of spring wheat, but the yield did not reduce obvious ly. Irrigation quota of 3 060 m3/hm2 (1 435 m3/hm2 less than comparison treatment) affected the growth of spring wheat badly: plant height reduced, dry weight and fresh weight decreased, yield reduced obviously. In common years, fi tting irrigation quota was 3 900~4 200 m3/hm2 and water-saving potential was 200~500 m3/hm2 in irrigation region in Ningxia.关键词
