1, after planting, water should be poured thoroughly, and the first time after planting walnut seedlings, the tree pit should be completely soaked with water to prevent the dry land at the bottom of the pit from being connected with the ground water. Although we require that the walnut trees should be planted in shallow pits, we should not dig too big pits when planting in places with poor watering conditions to prevent the water from being impermeable and reduce the survival rate.

2, autumn planting should be buried in the cold, autumn planting peach trees must be buried in the cold, the next spring after thawing the soil in time to dig out the seedlings and water them in time, and set dry.

3. Cover the tree tray with plastic film, and cover the tree tray with 80- 100 cm square plastic film after watering, so as to improve the low temperature and promote the growth of root system. Pay attention to the thick plastic film for medical use, and cover the plastic film with a layer of soil where watering is difficult, which can effectively keep water and reduce watering times.

4. After planting, stem should be fixed in time. After planting, the big seedlings should be fixed at 70-80 cm from the ground. The seedlings with insufficient stem height should be cut in short pieces (1/2-3), and the small seedlings should be cut in heavy pieces (1-2 full buds are left under the cut).

5, to prevent water loss, after drying, ready mixed paint should be used to seal the cut to prevent the wound from losing water. It is best to bury all seedlings with mounds for the seedlings or semi-finished products planted. Pay attention to the inspection after planting 15-20 days. After the walnut seedlings sprout, the mounds will be gradually removed.

6. Protect the bud. When the walnut seedlings germinate, attention should be paid to protecting the new buds to prevent the harm of leaf-eating pests (scarabs, big gray weevils, etc.) in spring. Window screens (or gauze) can be made into small tubes to cover the buds of the plastic belt. Note that a small rod should be tied inside the insect-proof bag to pick up the insect-proof bag to prevent the new strip from bending downward after it grows.

7. Remove sprouting in time. After the walnut seedlings germinate, the sprouting below the set dry seedling shaping belt should be removed in time. For the seedlings that have been re-cut and have not reached a certain dry height, one seedling should be selected to grow the strongest, and all others should be removed.
