Choose roots longer than 20 cm and diameter above 0.2 cm for transplanting.

3. Thinning and fixing seedlings

Thinning seedlings should be carried out as early as possible. The first thinning should be carried out when the seedling height is 6.0 cm, and the second thinning should be carried out when the seedling height is 10cm~12cm. For the fixed seedlings of hole sowing, 3 ~4 seedlings should be reserved for each hole, and for the seedlings of drilling sowing, 1 strong seedling should be reserved every 10cm~12cm; for the seedlings, 1 seedling should be reserved every 2.0 cm ~ 3.0 cm, and the large seedlings should be removed, leaving the seedlings to continue to grow. When too many seedlings are missing, it is best to reseed them with germinated seeds.

The above is the introduction of Astragalus membranaceus, Astragalus membranaceus planting area is relatively large, mainly in North China, Northeast China, Northwest China, to plant Astragalus membranaceus, we must master the above seedling methods.
