1. Planting period Before planting, the soil should be excavated first, and the large hole should be excavated 1 meter square. The topsoil and the heart and soil are separated. When backfilling, the topsoil is filled first, and the soil is filled. How many seedlings to use when planting, generally use 45 meters of plant spacing, 33 plants per acre, 1:10 pollination tree configuration ratio, each farmer fertilizer and topsoil mixed.

It is not too late to be planted in spring, otherwise it will be unfavorable for slow seedlings. Therefore, the walnut tree planting can be carried out after the soil is thawed until the end of March, and the earlier the better.
2, seedling selection
The quality of seedlings directly affects the success or failure of the construction of the park and the economic benefits. Therefore, it is necessary to select the varieties with excellent purity, the main roots of the seedlings are developed, the lateral roots are intact, no pests and diseases, strong branching, easy flowering, strong resistance, and the average plant height is more than 1 meter. , the base diameter is not less than 1cm, and the roots are more than 2 to 3 years old grafted strong seedlings.
3, seedling treatment before planting
Firstly, the roots of the seedlings are pruned, the main roots are cut off, the roots are cut off, and the roots are cut out according to the size of the seedlings. The bundles should be bundled in clear water immediately. The water depth is higher than the roots. It is suitable for grafting, soaking time for more than 12 hours, so that the roots absorb enough water. After the seedlings have absorbed enough water, they are placed in 2000 times ABT rooting powder solution for 5-20 minutes to increase the survival rate, and the quick-drying disinfection is carried out in a 0.5% carbendazim solution. Finally, the roots of the mud are taken to prevent the roots of the seedlings from drying out.
4, planting
When planting, first release water, water should be more than less, and then fill the mixture of topsoil and farmyard manure. When placing seedlings and placing seedlings, pay attention to the grafting part facing north (because the tree has lightness, the grafting part can adjust the crown distribution to the north. In addition, the northwest winds more to prevent the wind from breaking, and it is necessary to correct the right, then fill the soil, fill it with the west to the middle and fill it evenly. After filling the soil, it is advisable to gently lift the seedlings to the previous position, and the planting should not be too shallow or too deep. Too deep is easy to grow poorly, slow seedlings slow to affect the survival rate; too shallow is easy to lose water, resulting in dead seedlings.
5, post-plant management
After the seedlings are planted, the tree plate should be covered to prevent the running of the tree. The film size is 90cm2. Firstly, the ground is leveled. When the film is laid, the two people cooperate with the film center to pass through the center of the seedling, flatten it, and then use fine soil to press and compact the surrounding and seedling roots to prevent the wind from blowing the film. water. The saplings after planting are fixed and dried at a full bud of 60 cm to 80 cm. After drying, use a special bag to cover the trunk to prevent damage to the leaf-eating pests such as the chafer. After the temperature rises, the wind should be gradually removed and the bag removed. After germination of young trees, it is necessary to strengthen the management of soil, fertilizer, water and pests.
