摘　　要：莴笋品种绿竹表现中熟,植株生长势中强,叶色黄绿;具有肉质茎棒形均匀、皮绿肉青、纤维含量低、品质优良、抗病性强等显著特点,平均单株质量880 g,每667 m^2产量高达4815 kg,适宜甘肃及西北相同气候区域推广种植。绿竹在商品性、产量、抗病性方面有较大突破,可部分替代当地老旧品种。利用河西走廊地区的天然优势,总结了1套制种技术,主要内容包括制种田选择、播种、田间管理、病虫害防治及种子采收等,为实现莴笋良种良法的配套生产提供了保障。Asparagus lettuce cultivar lüzhu was a medium maturity cultivar and had medium strong plant growth vigor,yellow green leaves.It had the characteristics of homogeneous fleshy stem,green skin and cyan flesh,low fiber content,good quality and strong disease resistance.The average weight was 880 g per plant,and the yield was about 4815 kg per 667 m^2.It was suitable for promotion and planting in Gansu and Northwest China with the same climate.Lüzhu had great breakthrough in commodity,yield and disease resistance,which could partly replace the local old cultivars.Taking advantage of the natural advantages of Hexi Corridor area,a set of seed production technology was summarized,including the selection of seed production field,sowing,field management,disease and pest control and seed harvesting,which provided guarantee for the matching production of improved cultivars and methods of asparagus lettuce.
