The invention relates to a seedling raising and planting method for apocynum venetum. The method comprises the following steps of: adding decomposed cow and sheep dung into farmland soil in a weight ratio of 10:(1-3), adding 10 to 40 percent of compound fertilizer solution containing N, P and K, and stirring to prepare a viscous culture medium; loading the culture medium into a seedling raising bag made of non-weaving cloth formed by crushing crop straw, soaking apocynum venetum seeds in water at the temperature of 40 DEG C for 20 minutes, soaking the soaked seeds in 0.02 to 0.05 weight percent of NaOH solution or CuSO4 solution for 12 hours, fishing the seeds out, draining, putting into the seedling raising bag, and culturing at the temperature of between 15 and 20 DEG C for 2 to 4 days,wherein 2 to 4 grains of seeds are put into the seedling raising bag, and the germination rate is more than or equal to 95 percent; after apocynum venetum seedlings grow to germinate 8 pairs of true leaves, transplanting for field planting; performing nitrogen fertilizer topdressing before blooming, and performing phosphorus and potassium fertilizer topdressing during the mature period of the seeds; and cutting and harvesting follicles when the colors of the follicles are changed into deep yellow from green, threshing on a sunning ground to harvest the seeds, and conveying apocynum venetum stems to a flax production workshop. The seedling raising and planting method is suitable to be used in low-elevation subtropic zones.
