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 invention relates to a synthetic method of artificial seeds of picea mongolica. Somatic embryos induced by callus are used as artificial seed embryos of the artificial seeds, the somatic embryos are dried to serve as an embedding substance, artificial endosperm comprises 1 / 4 LM, 0.5 mg / L IBA and 20 g / L sucrose, artificial seed coats are prepared by immersing the artificial seed embryos and theartificial endosperm into an artificial seed coat solution for curing, and the artificial seed coat solution comprises sodium alginate with mass percentage concentration of 2-3% and CaCl2 with mass percentage concentration of 1.5-2.5%. The artificial seeds of the picea mongolica are not limited by seasons and have better nutrient supply and disease resistance. The synthesis of the artificial seeds of the picea mongolica can solve major problems of low yield of seeds of the picea mongolica, lack of seedlings, resource protection, maintenance of good traits and the like, and the picea mongolicais convenient to transport, so that the picea mongolica is better applied to timber forests for ecological construction and building such as sand treatment.

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...
