Problems solved by technology

Large cup seedlings of Camellia oleifera are generally 2-3 years old. Because the seedlings are larger and absorb more nutrients, the existing matrix formula cannot meet the nutritional needs of large cup seedlings. At the same time, the seedlings show weak growth, few branches, and some root rot

Abstract

The invention discloses a method for cultivating large-cup seedlings of camellia oleifera, which comprises the steps of seedling cultivation, large-cup seedling cultivation and nursery stock removal, selecting un-lignified or semi-lignified twigs of the current year on high-quality camellia oleifera trees as spikes, and placing Cutting seedlings are carried out in a seedling bag with a cutting medium, and then the 1a-old cutting seedlings are transplanted into a seedling container equipped with a seedling medium for large cup seedling cultivation. Select 2-year-old or 3-year-old, no pests and diseases, and the seedlings are fresh , normal color, strong growth, full seedling stem, no mechanical damage, full terminal buds, strong big cup seedlings emerge from the nursery. The present invention adopts a two-step method for container seedling cultivation, first inserting camellia oleifera spikes into a seedling-raising bag equipped with yellow mud to obtain cutting seedlings; The cultivation of large cup seedlings has good quality seedlings and a high survival rate of afforestation out of the nursery.

Description

technical field [0001] The invention belongs to the field of growing seedlings of economic forest species, and relates to a method for raising seedlings of camellia oleifera, in particular to a method for cultivating large cup seedlings of camellia oleifera. Background technique [0002] Camellia oleifera is an important woody edible oil tree species unique to my country. It is also known as the world's four major woody oil plants together with olive, oil palm and coconut, and is also known as my country's four major woody oil plants together with Chinese tallow tree, tung tree and walnut. At present, my country's Camellia oleifera covers an area of ​​about 60 million mu, which is widely distributed in 18 provinces (regions) in the south. The content of unsaturated fatty acid, oleic acid and vitamin E in tea oil is higher than that of olive oil. It is known as "Oriental olive oil" and has a very broad market prospect. [0003] According to statistics, about 70% of the exist...
