摘要

为优化豫北地区冬小麦在滴灌条件下的灌水技术参数

通过田间试验系统研究了不同滴头流量(2.0

4.0

6.0 L/h)和滴灌带间距(40

100

120 cm)对灌溉水在土壤中分布、冬小麦产量以及水分利用效率的影响。结果表明:就灌水均匀度而言

缩小滴灌带间距和增加滴头流量可以提高灌溉水在冬小麦根区的分布均匀度;本试验条件下滴灌带铺设超过80 cm

会影响冬小麦产量及其构成

滴灌带间距相同时

冬小麦产量随着滴头流量的增加呈递增趋势。就水分利用效率而言

适宜的滴灌带间距及滴头流量组合能在同一灌水条件下

有效减小耗水量并提高水分利用效率;本试验条件下滴灌带间距60 cm、滴头流量2.0 L/h的参数组合的产量最高

达到10 626.45 kg/hm2

水分利用效率最高

达到2.42 kg/m3。综合分析灌溉水均匀度、冬小麦产量以及水分利用效率

滴灌带间距60 cm、滴头流量2.0 L/h

以及滴灌带间距80 cm、滴头流量6.0 L/h的参数组合是适宜的冬小麦滴灌灌水技术参数。

Abstract

In order to optimize the drip irrigation technical parameters of winter wheat under drip irrigation in northern Henan province

the effects of different dripper discharges (2.0

4.0

6.0 L/h) and the spacing of drip irrigation lateral springs (40

100

120 cm) on soil distribution of irrigation water

winter wheat yield and water use efficiency were studied in a field experiment.The result showed that:In terms of the drip irrigation uniformity

reducing the distance between drip irrigation lateral spacing and increasing the dripper discharge could improve the distribution uniformity of irrigation water in the root zone of winter wheat.Under the experimental conditions in this study

the yield and composition of winter wheat were affected by the spread of drip irrigation lateral spacing over 80 cm

and the yield of winter wheat increased with the increase of the dripper discharge with the same drip irrigation lateral spacing.In terms of water use efficiency

the appropriate combination of drip irrigation lateral spacing and dripper discharge could effectively reduce water consumption and improve water use efficiency under the same irrigation condition.The present results suggested that the parameter combination of drip irrigation lateral spacing of 60 cm and dripper discharge 2.0 L/h had the highest yield (10 626.45 kg/hm2) and the highest water use efficiency (2.42 kg/m3).Through the comprehensive analysis of irrigation water uniformity

winter wheat yield and water use efficiency

the parameter combination of 60 cm drip irrigation lateral spacing

dripper discharge 2.0 L/h

80 cm drip irrigation lateral spacing

and dripper discharge 6.0 L/h were the optimal technical parameters for winter wheat drip irrigation.
