烤烟温床假植育苗,就是先在少数母床上播种育苗,待烟苗长到1—5片真叶时再移到假植床(也叫子床)上.烟苗在子床长成成苗后,再往大田里移栽.假植育苗方法有许多优点,烟苗肥壮,根系发达,苗距均匀合理,裁后成活率高,抗病能力增强.假植过程中烟苗主根被切断,促使侧根、须根大量发生,形成强大的根系.与不假植苗比较,侧根增加70%,须根增加1.5倍.此法育苗头一个月长在少数母床上,后一个月 Flue-cured tobacco hotbed nursery seedlings, is the first sow seedlings in a few mother beds until the tobacco seedlings grow to 1-5 true leaves and then moved to the fake seedbed (also known as sub-bed). After transplanting again in the field, there are many advantages of the method of planting seedlings, the flue-cured tobacco seedling is strong, the root system is developed, the seedling spacing is uniform and reasonable, the survival rate after cutting is high, the disease resistance ability is enhanced, Promote the lateral roots, fibrous roots occur in large numbers, forming a strong root system.Compared with not leave the seedlings, the lateral root increased by 70%, 1.5 times greater than the fibrous roots.
