Embodiment 1

[0026] The silverwood seed garden located in the national-level improved seed base of Xishan Forest Farm, Dazu District, Chongqing City is a seedling seed garden. Due to design defects, there is a problem that the same parents are adjacent to each other. In order to avoid huge losses caused by reconstruction, the present invention is used to carry out scientific transformation. , to achieve the perfect gorgeous transformation.

[0027] First, a per-tree survey of growth and seed setting traits was conducted on existing silverwood seed orchards. Since the trees in this example have not yet reached the age of flowering and fruiting, the good ones are removed from the bad ones according to the growth traits.

[0028] Taking the first district of the fifth district of the existing Yinmu Seed Garden as an example, the original planting map is as follows:

[0029]

[0030] Obviously, the parents (clones / families) in the original plan of the plot were arranged sequentially and fi...

Abstract

The invention relates to a method for transforming a forest tree seedling seed orchard into a seedling and clone mixed seed orchard, and belongs to the technical field of forest tree breeding. Comprising the following steps: (1) investigating and analyzing growth and fruiting data of an original seedling seed orchard; (2) formulating a superior-remaining and inferior-removing scheme and a stock setting diagram according to a growth and fruiting data analysis result; (3) redesigning by adopting seed garden design software; and (4) replacing the inferior individuals with clonal grafted seedlings. The seedling and clone mixed seed orchard is built from a seedling seed orchard. The method is ingenious in design and scientific, has the advantages of seedling and clonal seed gardens, can realize upgrading of the generations of the seed gardens through one-time reconstruction, is suitable for being applied to reconstruction of various forest seedling seed gardens, and has wide application value in upgrading and reconstruction of the forest seed gardens.

Description

technical field [0001] The invention belongs to the technical field of forest tree breeding, and in particular relates to a method for transforming a forest tree seed garden into a seed garden of seed and clones. Background technique [0002] Tree seed orchards are the cradle of most plantations. For a reliable and reproducible seed supply, tree seed orchards are often required or preferred, but because tree breeding is already in its infancy, genetic gain often becomes very important. Tree seed orchards are by far the most important interface between forestry and tree breeding and supporting research. Through tree seed gardens, we create the resources that future generations need, and tree seed gardens are also a tool to fight global warming and achieve sustainable development; better tree seed gardens mean a better future world. In addition, tree seed orchards also play an important role in protecting the genetic resources of trees. [0003] In the 1930s and 1940s, Nord...
