| 摘 要： | 以生菜品种绿领和弘农为材料,研究了春季不同播种期对水培生菜生长发育、产量和品质的影响。结果表明,不同播种期下生菜的产量和品质有显著差异,早播和晚播均降低生菜的产量和品质,播期为3月17日时产量最高,绿领和弘农分别为271.19 g/株和243.67 g/株;此播期的2个生菜品种VC含量也最高,且硝酸盐含量相对较低,表明选择适宜的播种期有助于提高生菜的产量和品质。

| Abstract: | The effect of different sowing date in spring on the yield and quality of lettuce（cv.Hongnong and Lvling） were investigated by using hydroponic system.The results showed that different sowing date significantly affected the yield and quality of lettuce.Early and late sowing decreased the quality and yield.The sowing date on march 17th showed the highest yield,271.19 g and 243.67 g per plant for Lvling and Hongnong,respectively,and the highest VC content was also obtained by this treatment,moreover,the nitrate content was lower than other sowing dates.The results indicated that suitable sowing time was beneficial to the improvement of lettuce quality and yield. |
