Problems solved by technology

In production practice, 1-year-old Phoebe bare root seedlings or container seedlings are mostly used for afforestation. After 2 to 3 years of afforestation, careful tending is required, and the cost of tending is high. If the management is not proper, problems such as low survival rate of afforestation and poor stand quality will easily occur.

Embodiment 1

[0044] Cultivate 1-year seedlings:

[0045] Stage 1: One-year seedling cultivation of Nannan

[0046] Seed collection: Select excellent mother trees over 20 years old, and collect seeds when the fruit turns from green to dark brown in October-November.

[0047] Seed storage: Remove the peel from the harvested fruit, rinse it with clean water, and dry it in a ventilated place, and store it in layers with moist fine sand, preferably 2-3 layers. During the process, keep the humidity of the sand properly, and the sand will dry to pan Spray a small amount of water when white.

[0048] Sowing seedlings: From late January to mid-February, mix the stored seeds with fine sand and sprinkle them on the germination bed. The amount of seeds used is 150g / m2~200g / m2, and the bed surface is smoothed so that the seeds do not overlap and no seeds are seen It is advisable to spray water at the right time. In the middle and late March, the seeds start to germinate, and the embryos are white. T...

Abstract

The invention provides a method for cultivating large and strong seedlings of phoebe bournei, and belongs to the technical field of plant cultivation. The method includes respective cultivation of 1-year-old seedlings, 2-year-old seedlings and 3-year-old seedlings of the phoebe bournei, the three stages are correlated with one another, and the later ones are the premise of the previous ones. Elaborate operations are carried out in each stage of seedling cultivation, the cultivated seedlings are strong and have high quality, and the survival rate and the forest quality of seedling afforestationare increased.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for cultivating strong seedlings of Phoebe nannuum. Background technique [0002] Phoebe bournei (Hemsl.) Yang is an evergreen broad-leaved tree of the genus Phoebe in the Lauraceae family. It is a national second-class rare and endangered species, and it is a precious native timber tree species in Jiangxi Province. Due to the long-term destruction of wild nanmu resources, the wild nanmu resources in my country are seriously insufficient at present, which cannot meet people's demand for precious nanmu timber. In recent years, Jiangxi Province has vigorously planted and developed Phoebe, and the plantation area of ​​Phoebe has been more than 200,000 mu. In production practice, 1-year-old bare-root seedlings or container seedlings of nanmu are mostly used for afforestation. After 2 to 3 years of afforestation, careful tending is required, and the cos...
