摘　　要：选取3个籽用西葫芦品种,分别采用平作和垄作2种种植模式和3个密度处理,研究了不同密度和种植模式对不同籽用西葫芦品种病害发生和产量的影响。结果表明:不同密度处理和种植模式对籽用西葫芦病害的发生有显著影响,在低密度垄作条件下,白粉病发病较轻,绵腐病不发生,高密度平作条件下,病害相对较重;同一品种不同种植模式下,垄作种植较平作种植产量显著增加;同一品种同一种植模式下不同密度处理中,低密度和对照较高密度处理产量高。目前,平作种植条件下,高密度种植不适宜河套灌区的籽用西葫芦生产,若要提高种植密度需要改变种植模式。The effects of different planting densities and planting patterns on disease occurrence and yield of seed zucchini were studied by selecting three seed zucchini cultivars and adopting two planting patterns(flat and ridge)and three density treatments,respectively.The results showed that different density treatments and planting patterns had significant effects on the occurrence of seed zucchini diseases.Under low density and ridge cultivation conditions,the incidence of powdery mildew was relatively light and that was no cotton rot.Under the condition of high density of flat cultivation conditions,the disease was relatively serious.Under different planting patterns of the same cultivar,the yield of ridge planting was significantly higher than that of flat planting.Under the conditions of different density treatments,same cultivar and same planting pattern,the yield of low density and control were higher than that of high density treatments.At present,under the condition of flat planting,high density planting is unsuitable for the production of seed zucchini in Hetao irrigation area.To increase the planting density,the planting pattern needs to be changed.
