Embodiment 1

[0036]In mid-October 2007, the fruiting strains of the whole compatriots of Cenxi Soft Branch Camellia oleifera, which were artificially controlled by pollination, were selected for fruit harvesting. The described Cenxi soft branch Camellia oleifera full sibs excellent family result strains are the full sib hybrids produced after artificial control of pollination by using the Cenxi soft branch Camellia oleifera excellent clones as parents, and the yield and main agronomic characters selected after family determination are all equal. High performing full-sib family. After the fruit to be harvested is slightly cracked, the seeds are taken out, and then the seeds with full grains, no diseases and insects, and a single grain weight of more than 2g are spread on a 3:2 mass ratio of river sand and fresh sawdust. Germination is carried out in the germination bed of the germination medium; the germination bed is set in the outdoor southward plot without stagnant water, and the humidit...

Embodiment 2

[0043] In mid-October 2008, fruit harvesting was carried out by selecting the fruiting strains of the whole compatriots of Cenxi soft branch Camellia oleifera through artificial control of pollination. The described Cenxi soft branch Camellia oleifera full sibs excellent family result strains are the full sib hybrids produced after artificial control of pollination by using the Cenxi soft branch Camellia oleifera excellent clones as parents, and the yield and main agronomic characters selected after family determination are all equal. High performing full-sib family. After the fruit to be harvested is slightly cracked, the seeds are taken out, and then the seeds with full grains, no diseases and insects, and a single grain weight of more than 2g are spread on a 3:2 mass ratio of river sand and fresh sawdust. Germination is carried out in the germination bed of the germination medium; the germination bed is set in the outdoor southward plot without stagnant water, and the humid...

Embodiment 3

[0050] In the first ten days of November 2008, the fruiting strains of the whole compatriots of Cenxi soft branch Camellia oleifera, which were artificially pollinated, were selected for fruit harvesting. The described Cenxi soft branch Camellia oleifera full sibs excellent family result strains are the full sib hybrids produced after artificial control of pollination by using the Cenxi soft branch Camellia oleifera excellent clones as parents, and the yield and main agronomic characters selected after family determination are all equal. High performing full-sib family. After the fruit to be harvested is slightly cracked, the seeds are taken out, and then the seeds with full grains, no diseases and insects, and a single grain weight of more than 2g are spread on a 3:2 mass ratio of river sand and fresh sawdust. Germination is carried out in the germination bed of the germination medium; the germination bed is set in the outdoor southward plot without stagnant water, and the hu...

Abstract

The invention discloses a method for constructing a Cenxi soft-branch Camellia oleifera full-sibling progeny forest, which includes the procedures of seed collection and seedling cultivation, seedling afforestation and stand management, and selects the Cenxi soft-twig camellia full-sibling excellent family fruiting strains pollinated by manual control for seed collection Seedling cultivation, get a suitable Cenxi soft branch Camellia oleifera container post-emergence afforestation, after afforestation and carry out stand soil management and tree management, when the crown width of the plant reaches 0.8‑1.0m2, start to regulate its vegetative growth and reproductive growth, and promote the flowering of the stand Strong and productive. The present invention provides a method for constructing Cenxi soft-twig Camellia oleifera all-sibling progeny forest with the characteristics of short period, quick production and high early operating benefits, further optimizing the planting structure of Camellia oleifera in my country, protecting the genetic diversity of Camellia oleifera and high-generation varieties of Camellia oleifera It is of great practical significance to improve and speed up the construction of high-quality and efficient raw material forest bases of camellia oleifera in my country, to cultivate new economic growth points for the camellia oleifera industry, to support the development of poor areas, and to strengthen the construction of ecological civilization.

Description

technical field [0001] The invention belongs to the technical field of forest cultivation, and in particular relates to a method for constructing a progeny forest of all compatriots of Cenxi soft-branch Camellia oleifera. Background technique [0002] The woody oil industry is a traditional industry in my country, an industry that benefits farmers the most, and an important source of healthy and high-quality edible vegetable oil. In recent years, the consumption of edible vegetable oil in my country has continued to grow, the demand gap has continued to expand, the degree of dependence on foreign countries has increased significantly, and the safety of edible vegetable oil has become increasingly prominent. In order to speed up the development of the woody oil industry, vigorously increase the supply of healthy and high-quality edible vegetable oil, and effectively maintain the national grain and oil security, the State Council issued the "Opinions on Accelerating the Develo...
