不同品种、播期对春苔干性状及产量的影响

Effect of Different Varieties,Sowing Date on Characters and Yield of Spring Lactuca sativa L. var

目的:筛选适合涡阳春季栽培的苔干品种。方法:采用两因素4水平完全随机区组设计,共16个处理,考察不同品种、播期对春苔干性状及产量的影响。结果:老来青品种熟期早,单株产量高,达0.433kg,但出干率较低。竹叶青品种早熟性,长势、耐热性、肉色深绿品质均好,出干率高,达4.96%。皇子、一米青两品种产量较低,且皇子品质差,一米青耐热性差。结论:竹叶青品种最适宜作为春苔干栽培,老来青品种次之,皇子、一米青两品种不宜作为春苔干栽培。

Objective： In order to select suitable Lactuca sativa L. var yemena X. S. Shen et X. P. Zhang variety for spring cultivation in Guoyang county. Methods：16 treatments of two factors, four levels were designed in a com- pletely random area. Results：Laolaiqing was earlier ripe, single plant yield higher , reaching 0.433 kg, but the dry rate is lower. Zhuyeqing was precocious variety, growing, heat resistance, meat dark green quality, high dry rate, up to 4.96%. Yield of Huangzi and Yimiqing varieties is low, and poor quality of Huangzi ,poor heat resist- ance of Yimiqing. Condusion： Zhuyeqing was the most suitable Lactuca sativa L. var cultivating in spring season, followed by Laolaiqing, but Huangzi and Yi miqing varieties were not suitable for spring cultivation in Guoyang county.
