摘　　要：以西芹"加州王"为试材,研究了覆膜穴播压沙西芹栽培模式下不同种植密度、不同灌溉量、不同压沙量、喷施不同微肥对西芹生育期、经济性状以及病害因子的影响,以期为西芹优质高产栽培提供理论依据。结果表明:覆膜穴播压沙栽培模式下该地区西芹最佳种植密度为6万株/667m2,最佳灌溉量400m2/667m2,合理用沙量1m2/667m2,喷施微量元素对西芹抗病性、提高产量影响比较明显,其中使用磷酸二氢钾效果最好,其次是硼肥、锌肥。Taking celery＇Jiazhouwang~ as material, with plastic mulching and hole seeding covered with sand cultivation, the effect of celery plant density, water saving, reasonable sand volume and application of trace elements were studied. The results showed that the optimum plant density was 60,000 plants per 667 me ,the irrigation volume was of 400 m2/667m2 and reasonable use of sand volume was of 1 m2/667m2. Spraying trace elements had a significant effect on enhancing celery disease resistance and increasing yield. Among the trace elements for test, potassium dihydrogen phosphate was the best,followed by were boron fertilizer and zinc fertilizer.
