表 Please select and fill in the relevant technical information according to the following technical classifications for specific technologies.
Technical link Key technical points Implementation season / month 1. Planning / designing of shelterbelt Insert 1: Planting scheme: shelterbelts compromise 2-5 tree lines forming the windbreak about 5-15 m wide and 15-25 m high.
Insert 2: Rectangle grid layout of shelterbelts. Spacing of the rows is denser against the prevailing wind.2. Selection and collection of trees seedlings 3. Clearing and preparing land for planting of shelterbelts late autumn and spring 4. Pits for planting the seedlings are dug 5. Tree seedlings are planted late spring 6. After planting each seedling is watered for up to two years Schedule or attachment (with relevant technical parameters, add schedule or attachment information here)
