在番茄早熟生产栽培中,培育健壮秧苗具有重要意义,适宜的苗龄又是培育健壮秧苗的重要一环.番茄苗龄可分为二种:一是用秧苗的生长发育状态表示的生理苗龄,如子叶苗、三叶苗等;二是用从播种至大田定植所经历的天数表示的绝对苗龄,如50天龄、80天龄等.我省在番茄育苗中,具有八片真叶的生理苗龄是公认的壮苗标准.但在育苗中,利用工厂化育苗和传统方法育苗,番茄秧苗的绝对苗龄会出现很大 In tomato precocious cultivation, cultivating robust seedlings is of great significance, suitable seedling age is an important part of cultivating robust seedlings.Tomatoid seedling age can be divided into two kinds: First, the seedling growth and development state that the physiological seedling age , Such as cotyledons, trilobal, etc .; the second is from the sowing to Daejeon colonization by the number of days represented by the absolute seedling age, such as 50 days of age, 80 days of age, etc. In our province in tomato nursery, with eight true leaves Of the physical seedling age is recognized as a strong seedling standard.But in the nursery, the use of industrialized nursery and traditional methods of nursery, the absolute seedling age of tomato seedlings will be great
