Planting techniques of Phoebe bournei seedlings

1. Seedling cultivation techniques of Phoebe bournei:

The seed maturity of Phoebe bournei is around the light snow solar term, when the pericarp changes from cyan to blue-black. The collected fruits should be treated in time. The processing method is as follows: mash the fruit in a washing basket or wooden bucket, peel it, then rinse it with clear water, dry it in a cool place indoors to avoid the sun, and store it after the water is slightly dry. The 1000-grain weight of this tree species is 20 ~ 345g, and the germination rate in nursery can reach 80% ~ 95%. The water content of seeds is about 30%, which is easy to lose water and crack, leading to mildew of cotyledons and loss of germination ability. Therefore, the treated seeds must be immediately mixed with wet river sand for storage. Before and after the solar term in beginning of spring, a large number of seeds began to germinate, so you can sow at this time.

2. Growth management

Nanmu seedlings, which grow slowly in the early stage and like humidity, should choose fertile and humid soil with short sunshine time, convenient irrigation and drainage as nursery land. The soil is sticky, the drainage is not smooth, and it is prone to root rot; If the soil is dry and short of water, the seedlings will not grow well and will easily cause burns. Before sowing, apply sufficient base fertilizer to the nursery, and carefully prepare the soil and build the bed. Generally, drilling is adopted, with a spacing of 15 ~ 20cm, a width of 6 ~ 10cm and a sowing amount of 20kg per 667m2 (1mu).
