How should cutworms be controlled in Angelica sinensis
Cutworms, also known as "ground silkworms" and "black ground silkworms." They belong to the order Lepidoptera, family Noctuidae. The cutworms affecting Angelica sinensis are mainly the black cutworm and the yellow cutworm, and their damage and control measures are the same. 1. Damage: The larvae damage Angelica sinensis seedlings, hiding by day and emerging at night; at the young instar stage they mostly damage tender leaves and tender growing tips, biting through the root crown and causing missing plants and broken rows. 2. Morphological characteristics: The adult black cutworm has a body length of 16-23 mm and a wingspan of 42-54 mm. The female moth's antennae are filiform, and the male moth's are bipectinate. The forewing is dark brown between the costal margin and the outer transverse line. Between the inner transverse line and the outer transverse line there are distinct kidney-shaped markings, ring-shaped markings and rod-shaped markings. The hindwing is grayish white, with the veins and margins dark brown. The abdomen is gray. The egg is hemispherical, initially milky white, later turning yellow, and grayish purple just before hatching. Mature larva: body length 37-47 mm. The head is yellowish brown, the body is yellowish brown to dark brown, with pale longitudinal bands on the back. The body surface is rough, covered with small round black granules. The anal plate is yellowish brown, with two dark brown longitudinal bands. Pupa: body length 18-24 mm. Reddish brown and glossy.

Why should the roots of Schisandra chinensis be pruned before transplanting?
The benefit of pruning the root hairs of Schisandra chinensis seedlings before planting is: after the roots are cut, the seedlings can be stimulated and encouraged to generate and grow new roots. The length of the roots left after cutting is generally best kept between 10-12cm; seedlings with roots shorter than 10cm should also be trimmed so as to promote the growth of new roots.
