摘要:

【目的】研究西北干旱半干旱地区苜蓿种植适宜的灌溉方式。【方法】设计滚移式喷灌W1、指针式喷灌W2、浅埋滴灌W33种灌溉方法,并对比研究各种灌水方法对土地水分和紫花苜蓿产量以及灌溉用水效率等的定量影响。【结果】浅埋滴灌处理在苜蓿生长期内0~100 cm土壤含水量都显著高于滚移式喷灌处理和指针式喷灌处理(P<0.05),浅埋滴灌能够有效提高土壤水分含量。浅埋滴灌四茬总产量为15 094.10 kg/hm2,较滚移式喷灌和指针式喷灌提高了7.15%、6.67%。四茬平均灌溉水利用效率提高了40.59%、41.29%。浅埋滴灌的纯利润为6 263.56元/hm2,较滚移式喷灌、指针式喷灌分别提高了37.86%、34.69%。【结论】浅埋滴灌可以明显改善土壤水分状况,提高紫花苜蓿产量和灌溉水利用效率,增加种植紫花苜蓿的利润,水资源短缺地区选用浅埋滴灌作为灌溉方式。

Abstract:

【Objective】 To explore suitable irrigation methods for alfalfa cultivation in arid and semi-arid areas of northwest China.【Methods】 Three kinds of irrigation methods, rolling irrigation W1, pointer sprinkler irrigation W2 and shallow drip irrigation W3, were designed to implement irrigation, and the quantitative effects of various irrigation methods on land moisture, alfalfa yield and irrigation water efficiency were compared and studied.【Results】 The results showed that shallow-buried drip irrigation treatment significantly increased soil water content at 0-100 cm during the growth period of alfalfa compared with rolling sprinkler irrigation treatment and pointer sprinkler irrigation treatment (P<0.05), and shallow-buried drip irrigation could effectively improve soil water content.The total yield of shallow-buried drip irrigation was 15,094.10 kg/hm2, which was increased by 7.15% and 6.67% compared with rolling and pointer sprinkler irrigation.The average water use efficiency of four crops increased by 40.59% and 41.29%.The net profit of shallow-buried drip irrigation was 6,263.56 yuan /hm2, which was 37.86% and 34.69% higher than that of rolling sprinkler irrigation and pointer sprinkler irrigation.【Conclusion】 Comprehensive analysis shows that shallow-buried drip irrigation can significantly improve soil moisture status, improve alfalfa yield and irrigation water utilization efficiency, and increase the profit of alfalfa planting.Therefore, shallow-buried drip irrigation is recommended as an irrigation method in water resource shortage areas.
