| 中文摘要: |
| 为筛选出与冬小麦种植相适宜的滴灌带配置方式,对比分析了1管4行(处理A)、1管5行(处理B)、1管6行(处理C)三种不同的滴灌带铺设方式下冬小麦生长、产量的差异。结果表明,在不同滴灌带配置方式下,滴灌冬小麦叶面积指数(LAI)均随生育进程呈先升后降趋势,处理A在整个生育期内LAI始终高于处理B和处理C;旗叶叶绿素含量(SPAD值)在开花期以前表现为处理C>处理B>处理A,进入灌浆期后各处理的SPAD值均不同程度下降,呈现出处理A>处理B>处理C的态势;各处理单株干物质积累在生育期内呈“S”型变化趋势,处理A的叶、穗干物质积累分别较处理C高出17.39%和0.69%;产量差异在处理间均达到显著或极显著水平,处理A比处理B、处理C分别增产10.97%和37.71%。综合考虑到投入与产出,尽管处理B在三种处理中各方面表现中等,但其在实现节水的同时,产量(7 122.46 kg·hm-2)高于处理C,滴灌带用量较处理A减少了3 333.4 m·hm-2,因此在本试验条件下冬小麦滴灌带的配置方式以1管5行较为合适。 |

| The aim of this experiment was to find out the pipeline layouts with combined benefits of drip irrigation. Three arrangements were established in winter wheat field as one pipe for 4 rows (treatment A,TA),5 rows (treatment B,TB) and 6 rows (treatment C,TC),respectively,following randomized block design. The results showed that leaf area index (LAI) was the highest in TA,followed by TB and TC during whole growth period. SPAD value of flag leaf was the highest in TC,followed by TB and TA before blossom,then decreased,and showed descending order of TA,TB and TC since the onset of filling stage. Dry material in TA was 17.39% and 0.69% higher than that in TC in leaf and ear,respectively. The differences in yield between treatments were significant,and yield in TA was 10.97% and 37.71% higher than that in TB and TC,respectively. TB was the best choice for its modest yield (7 122.46 kg·hm-2) and cost-effective (less cost in pipe line). |
