1. Seed collection

Choose strong mother trees with a diameter at breast height of 20 to 40 cm for seed collection. When the peel turns from green to blue-black in late July, the stone fruit is mature and should be harvested immediately. Seed-collecting cloth is spread flatly under the tree canopy, and upper trees are shot down with bamboo poles. After harvesting the fruit, remove the branches, leaves and green fruits, place the fruit in a bamboo basket, rub the fleshy outer peel with your feet, and then immerse it in water and rinse it clean. Since the seed collection season is in midsummer and the temperature is high, the seeds are difficult to store and should be sown as they are collected. The grain yield is 51%, the seed weight is 280-320 grams, and the weight of seeds is about 3350 grains per kilogram.

2. Cultivation of seedlings

You should choose a forest clearing sheltered from the wind, preferably loose, fertile sandy loam or medium loam. If you use flat land or farmland as a nursery, you should choose a nursery with tall buildings, trees, walls, etc. in the northwest direction. Drill sowing is used, and the distance between rows is 20 to 25 cm. Before sowing, soak the seeds in warm water at 35°C for 24 hours to promote neat germination and unearth them in advance. After sowing, cover the seeds with a layer of charred mud 2 to 3 cm thick and cover with Wolfgrass or straw. Since the sowing season is in midsummer, with high temperatures and strong sunlight, the stems and leaves of seedlings are easily burned. A shade shed should be set up immediately after sowing with a light transmittance of about 30%, and the shade shed should be removed in mid-September. Unearth begins 15 days after sowing. After most of the seedlings are unearthed, the grass can be removed. Weed and fertilize promptly. Nitrogen fertilizer can be applied twice in September. After autumn, it is best to spray 0.5 to 1.0% borax once a week. By early November, set up a greenhouse before the early frost arrives to prevent early frost and cold snaps. Those who raise seedlings in the forest do not need to build shade sheds or greenhouses to save labor, materials and costs. Phoebe phoebe grows slowly in the seedling stage. The height of the seedlings is only 10 to 15 centimeters, the root diameter is 0.2 to 0.3 centimeters, and the yield of seedlings per acre is 40,000. The following year, beds need to be left or transplanted for one year before afforestation can be carried out on the mountain. 1. Selection of afforestation land

Phoebe phoebe likes moisture and tolerates shade, and has higher requirements for the site conditions of the forest land. To avoid overly dry and infertile soil, the afforestation land should be selected below an altitude of 800 meters, with deep and loose soil. , fertile, moist and well-drained hillsides and valleys, preferably neutral or slightly acidic soil.

2. Land preparation method

Use block land preparation. Dig a planting hole with a diameter of 60 cm and a depth of 50 cm.

3. Afforestation density

The afforestation density is 2.5×3.0 meters between plants and rows (that is, 88 plants per acre) or 2.0×2.0 meters between plants and rows.

4. Afforestation methods

In order to improve the survival rate of afforestation, most of the leaves should be cut off before planting, leaving only the petioles and 2 to 3 leaves. It is best to put base fertilizer and backfill topsoil. When planting, make sure the seedlings are upright, the roots are comfortable, and the soil is tight.

5. Afforestation season

It is suitable for afforestation in March, but not too early. The survival rate can reach more than 95%. 1. Young forest tending

After afforestation, timely tending should be carried out that year to prevent weeds from competing with seedlings for fertilizer. From now on, weed and loosen the soil twice a year, and fertilize appropriately. When raising, you should pay attention to pruning and shaping, and cultivate the stem shape.

2. Thinning and main cutting periods

Phoebe phoebe grows rapidly, with a thinning period of 12 to 15 years and a main cutting period of 25 to 35 years. Phoebe shavings have strong tillering ability, and can be regenerated after clear cutting.
