滴灌春小麦生长发育与水分利用效率的研究
Spring wheat growth and water use efficiency under drip irrigation
摘要
Abstract
Two irrigation ways between dripping and conventional models were analyzed, and two lay-out methods was also established under the drip irrigation, one tube with four rows and one tube with six rows. The object of the experiment was to analyze the relationship between spring wheat growth and water use efficiency under different irrigation ways and different lay-out of drip irrigation. The results showed that dripping irrigation could not only increase plant weight, SPAD value of flag leaf and root activity, but also reduce dry matter in vegetative organs, so it was beneficial to increasing yield. Compared with the conventional watering way, dripping irrigation decreased water amount by 25 % , while kernel yield increased by 14.4% and irrigation water use efficiency (WUE) increased by 35.4% under dripping irrigation . It had an obvious promoting effect on wheat growth in the treatment of one tube with four rows, meanwhile, increased yield and irrigation water use efficiency, owing to the relative even soil water distribution and plant uniformity under middle row and border row.关键词
