1. land selection and soil preparation: there are two kinds of land selection, namely, the selection of nursery land and the selection of planting land. Nursery land is usually planted in sandy soil or loam with relatively loose soil, good drainage and irrigation, and close to the water source area. Only the soil with sufficient water, fertile soil, rich organic matter and low soil viscosity can be planted in the planting area. When preparing the soil, the soil quality in Miao Di should be refined and leveled, and the whole cultivation or hole cultivation can be used, but the base fertilizer must be laid well. The base fertilizer is mainly organic fertilizer or agricultural machinery fertilizer, and then other trace fertilizers can be supplemented according to the characteristics of the soil.

2. Seeding and seedling raising: Before sowing, seeds need to be stored in river sand to accelerate germination, preferably indoors, and indoor doors and windows should be sealed and disinfected to avoid affecting the germination efficiency of pine trees. Under normal circumstances, it is necessary to accelerate the germination of seeds in winter this year, and sow in spring the following year. When sowing, the seedbed should be disinfected, and then the seeds should be evenly sown by drilling, covered with a layer of plastic film or straw for heat preservation, and anything used for seedling raising elements should be disinfected.

3. Seedling management: After sowing, we should pay attention to the water management in the seedbed and water it properly. Generally, we should sleep for about one month after sowing. During this period, we should prevent rats or birds from harming the seedlings. We can sprinkle some baits with chemicals in the field and spray them with carbendazim or ferrous sulfate every seven to ten days, which can enhance the immunity of the seedlings and prevent diseases. Then it is necessary to loosen the soil and weed for many times during the growth of the seedlings, which can promote the growth of the seedlings. Finally, when the seedlings grow to about ten centimeters, they can be transplanted.

4. Reasonable close planting: Because pine trees need to be transplanted many times to grow into big trees, the density of each transplant is different. In the first transplant, the basic rows only need to be planted at a distance of 3 cm per row and 3 cm per plant, while in the second transplant, the rows are generally 6 cm and the plants are 5 cm, and in the third transplant, the rows are generally 1.5 m and the plants are 1 m, and the spacing is appropriately increased each time.

5. field management: soil preparation and fertilization are required for each transplant, and topdressing and watering are carried out according to its growth, as well as the most basic intertillage weeding and ridging. At the same time, the branches and leaves are trimmed and shaped to ensure the growth and tree shape of pine trees.

6. Pest control: The main pest of pine trees is aphid, which occurs most frequently during the young trees of pine trees. It not only harms the branches and leaves of pine trees, but also directly leads to the death of young trees in severe cases, and it often occurs in June and July in summer. We can use dimethoate emulsifiable concentrate to control it. Secondly, pine trees often suffer from needle drop, which is different from normal needle drop. Normal needle drop will not lead to baldness of pine trees.
