番茄穴盘育苗苗龄和营养面积的研究

Study on Age and Nutritive Area of Tomato Seedlings Grown in Plug Tray

不同的营养面积对番茄秧苗质量的影响随着苗龄的增加而作用明显 ,全面衡量苗龄对产量形成的影响及穴盘育苗所能给予的营养面积 ,番茄穴盘育苗应提倡中龄苗定植。苗龄大小与育苗营养面积大小都会对产量形成产生明显的影响 ,前者产量时期的分布趋向于前高—后低或前低—后高 ,在总产量上得到一定程度的平衡 ;而后者随着营养面积的减小 ,产量水平逐渐下降。

The effect of nutritive area on growth of tomato seedlings were gradually increased along with the age of seedlings becoming elder. It is recommended to transplant middle age seedlings by evaluation of effects of seedling age and plug tray nursery area on yield formation. Seedling age and nursery area had significant influences on yield formation, of them, there were no significant differences in tomato total yield among seedling ages, while there were significant differences among nutritive area in tomato among seedling ages,yield which gradually decreased with the nutritive area decreasing .
