Embodiment Construction

[0019] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0020] The large-scale breeding seedling technology of oak seeds is characterized in that: it is implemented according to the following steps:

[0021] 1) Insecticidal treatment, fumigation and microwave insecticidal methods are not suitable for insecticidal treatment of Quercus seeds. 0.5% omethoate or warm water with a small amount of potassium permanganate at 50°C can be used for insecticidal treatment of seeds; potassium permanganate The ratio with water is 1:500;

[0022] 2) Rinse, rinse with water to remove empty and rotten seeds;

[0023] 3) Storage, low temperature 4-5 ℃ moisturizing storage, use woven bags for half bag storage or wet sacks to pack tree seeds, and immediately store them in a constant low temperature cold storage after harvesting, which can effectively preserve seed vitality and inhibit radicle germination;

[0024] 4) Pretreatment before sow...

Abstract

The invention discloses a technology for large-scale breeding of seedlings of quercus acutissima seeds. The technology is characterized by conducting the following steps of insecticidal treatment, rinsing, storage, pre-treatment before sowing, sowing, seedling management, pest control and the like. The breeding method has the advantages of high growth rate, thick and robust seedlings, high survival rate, high yield and the like, and is suitable for large-scale breeding of the seedlings.

Description

technical field [0001] The invention belongs to the technical field of forestry tree breeding, in particular to the large-scale seedling breeding technology of oak seeds. Background technique [0002] The genus Quercus (Quercus L.) belongs to the Fagaceae family and is distributed in northern temperate and tropical alpine regions. Quercus is one of the important forest trees, and it is also a tree species with multiple functions such as wood, charcoal, dye, cork, and tussah silkworm breeding. It is distributed in all provinces in the north and south of my country. Studies in many Quercus distribution areas, including North America, Europe, and the Himalayas, have confirmed that Quercus plants generally have poor seed regeneration ability. Insect pests lead to stunted development, and when they mature, they face the feeding pressure of animals, coupled with the influence of microenvironment, fire disturbance, firewood cutting and other disturbances, the proportion of seeds t...
