摘要

以塑管渗灌技术为基础发展起来的简易微喷灌技术

除具有渗灌的优点外

还具有可移动、投资小、简便灵活、适应性广等特点。小麦越冬期即使补水量不大

也可使土壤水分有明显的增加

到翌年春

50～80 cm 土层含水量补水田高于对照2.57%。小麦返青期补水0～30cm土层平均比对照高3.39%。1997-1998 年在特殊干旱条件下

不同补水时期的增产效应为抽穗期>拔节期>返青期。补水量在450m

/hm

以内

随补水量的增加

增产幅度增大。地膜覆盖加补水产量增加366.0～1324.5kg/hm

增产率为25.0%～90.4%。裸地麦田补水产量可增加315.0～701.6kg/hm

增产率为22.5%～50.2%

产投比为1.2～1.6。实践证明该技术可操作性强

具有广阔的推广应用前景。

Abstract

The advantages of micro-sprinkling irrigation method are moving easily

low investment

simple structure and extensive adaptability. After irrigating 200～400m3/ha

soil water content will be increased quickly. The suitable irrigation times are heading stage

jointing stage and turning greenstage. Between irrigation 200～400m3/ha

wheat yield increasement depends on the increasement of irrigation. Under film mulching

after irrigating

wheat yield increased by 25.0%～90.4% compared with no irrigating. It is 22.5%～50.2% higher than no-irrigating under wheat farmland of no-film mulching. Micro-sprinkling irrigating method is practical and worth being extended.
