What kind of wood doesn't have bugs?

Cinnamomum camphora has insecticidal properties. The main reason is that camphor is contained in the sap of Cinnamomum camphora wood, and its smell has a strong repellent effect on many insects, so many insects will avoid Cinnamomum camphora, and users especially like to use Cinnamomum camphora as a box to protect stored clothes from pests. Camphor is mainly secreted by the trunk of camphor tree, but not by the leaves, so the leaves have no insect repellent effect.

Precautions:

1. Generally, only 600-700 camphor trees are planted per mu in camphor tree field, but the planting amount of camphor tree seedlings per mu is 1200- 1400. Through reasonable close planting, one is to improve the reproductive capacity of land per unit area and increase 600-700 camphor trees per mu.

2. Explore the application of the new technology of secondary transplantation in Cinnamomum camphora seedling raising (that is, transplant the taproot of the current year to the two-year seedling for one time, and plant more than 6,000 plants per mu. Two-year-old big root seedlings were transplanted to nursery for sale for the second time, and planted per mu1more than 500 plants).

3. Combined with chemical fertilizer application, thin application of chemical fertilizer and coordinated application of phosphorus and potassium fertilizer, it can promote the growth of fertilizer roots to the plough layer, form dense fibrous root groups, and ensure that the sold seedlings are muddy and transport-resistant, and the survival rate is over 99%, which is 5%-9% higher than that of conventional seedlings and about 18% higher than that of direct seedlings.
