Embodiment Construction

[0031] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0032] The invention provides an artificial seed of spruce spruce, comprising an artificial seed embryo, an artificial endosperm and an artificial seed coat coated outside the artificial seed embryo and artificial endosperm, and the artificial seed embryo is obtained by inducing a callus. Somatic embryo, a part of the somatic embryo is directly embedded, and the other part of the somatic embryo is used as an embedding after drying. The artificial endosperm includes 1 / 4LM, 0.5mg / L IBA and 20g / L sucrose, the artificial seed coat is made by immersing the artificial seed embryo and artificial endosperm into the artificial seed coat liquid and solidifying, and the artificial seed coat liquid includes 2-3% sodium alginate and a mass percentage concentration of 1.5-2.5% CaCl 2 .

Abstract

The present invention relates to a method for synthesizing artificial seeds of spruce spruce. The artificial seed embryo adopts the somatic embryo induced by callus, and the somatic embryo is used as embedding after being dried, and the artificial endosperm includes 1 / 4LM, 0.5mg / L of IBA and 20g / L of sucrose, the artificial seed coat is made by immersing the artificial seed embryo and artificial endosperm into the artificial seed coat liquid and solidifying, and the artificial seed coat liquid includes the mass percentage concentration 2-3% sodium alginate and 1.5-2.5% CaCl by mass 2 . The sandy spruce artificial seed of the invention is not limited by seasons, and has better nutrient supply and disease resistance. The synthesis of artificial seeds of spruce sand will solve major problems such as low seed yield, shortage of seedlings, resource protection and maintenance of excellent traits of spruce sand, and it is also convenient for transportation, so that spruce sand can be better used in sandy land Ecological construction such as governance and construction of timber forests.

Description

technical field [0001] The invention belongs to the technical field of forestry vegetative propagation, and in particular relates to a method for synthesizing artificial seeds of spruce sanda. Background technique [0002] Sand spruce (Picea mongolica) is a rare and precious tree species in the world. It is the only spruce tree species distributed in arid and semi-arid sandy land. Emeralds" and "Living Fossils". Its natural forests are only distributed on the eastern edge of the Hunshandake Sandy Land in my country, and the Baiyinaobao Nature Reserve in Hexigten Banner is the most concentrated. It is one of the unique native tree species in the Sandy Land of Inner Mongolia. The existence of spruce forests in the sandy land plays an irreplaceable role in the construction of my country's three-north shelterbelt, windbreak and sand fixation, control of land desertification, and improvement of the environment of the farming and pastoral areas on the eastern edge of the Hunshand...
