摘  要：
在甘肃河西走廊沿祁连山高海拔冷凉气候区开展西芹种植密度、节水灌溉及有机肥施用技术研究。结果表明:该区域西芹最佳种植密度为7 411株/667m2,垄植沟灌,垄面宽40cm、垄沟宽20cm、每垄种2行、株距30cm。应用隔沟交替灌溉(灌水量为正常灌水量的80%)对西芹的生长和产量无显著影响,水分利用率为75.1kg/m3,较对照增加16.0%。配施矿物质有机肥可以显著降低西芹硝酸盐含量,提高单重和产量,增加效益;在当地最佳施肥水平下减量10%并配施矿物质有机肥150kg/667m2与当地最佳施肥水平处理的西芹产量没有显著性差异。

摘  要：
Techniques on planting densit,high-efficient water-saving irrigation methods and organic fertilizer application of celery in Hexi corridor high-altitude cold area were studied.The results indicated that the best planting density was 7 411 plant/667m2.Using the ridge and furrow irrigation,row spacing was 40 cm,furrow width was 20 cm,planting distance was 30 cm.Alternate furrow irrigation(AFI,neighboring two furrows alternatively watered) had no significant effect on plant weight and yield.AFI reduced 'luxury'transpiration,resulting in higher water use efficiency.Furthermore,about more than 14.3% of water could be saved,while water use efficiency was improved by 16.0% as compared with CFI.It was concluded that AFI was a feasible method of celery cultivation in Hexi corridor high-altitude arid areas.The plant weight and yield at combined application of mineral organic and fertilizer significant higher than no mineral organic.There was no significant between combined application of mineral organic,fertilizer reduce 10% and local best fertilization treatments.
