[0024] Photobark tree cutting propagation

[0025] Cut the semi-lignified cuttings from the living branches of the light bark tree in the open bacteria-carrying environment, remove the leaves and leave the petiole, each section is about 8-10cm long (with 2 nodes left); the base of the cuttings is placed in 1000ppm KIBA The solution was quickly dipped in the solution for 5 seconds; the cutting matrix was prepared from peat soil, perlite and yellow core soil at a volume ratio of 1:1:1; In the plug tray containing the substrate, pour the disinfectant potion thoroughly, and the disinfectant potion uses 58% Ruifu mold-manganese zinc wettable powder: water as a solution with a weight ratio of 1:1000; the cutting plug tray is placed in a fully automatic spraying greenhouse. Seedling stage management, regular fertilization and spraying, after 30 to 40 days of cuttings, the rooting rate will reach more than 90%, and after 50 days, the cuttings will take root and form a complete plant (...

Abstract

The invention relates to a fast reproduction technology of cornus wisoniana. The fast reproduction method of cornus wisoniana provided by the invention comprises the following process: (1) the selection of cutting materials: semi lignified cutting materials are selected; (2) the hormone pre-treatment of cutting materials; (3) the preparation of sticking matrix; (4) the sticking of the cutting materials: the cutting materials after hormone pre-treatment are stuck in the matrix, and disinfectant is poured; (5) seedling period management. The fast reproduction method of cornus wisoniana provided by the invention can realize the fast reproduction of the cornus wisoniana, and plays a very important role and is significant in speeding up the cornus wisoniana excellent clone promotion and promotes the construction of biological diesel raw material construction.

Description

technical field [0001] The invention relates to a technique for rapid propagation of a plant of the genus Cornaceae genus glabra. Background technique [0002] Swida wilsoniana Wanger, also known as Swida wilsoniana Wanger, also known as Swida wilsoniana Wanger, is a deciduous tree of the Cornaceae family. It mainly grows in the central and southern regions of my country, and is concentrated in the limestone areas from the Yangtze River Basin to the southwest. It is also distributed in the Yellow River and the south of the river, and is vertically distributed below 1000 meters above sea level. Each large tree can produce more than 50 kg of dried fruit per year, up to 150 kg. Both pulp and kernels contain oil, with an oil content of 30% to 36%, and an oil yield of 25% to 30%. The average oil yield per plant is more than 15 kg. [1，2] , oil mainly contains C 16 and C 18 It is a series of fatty acids, of which the linoleic acid content is nearly 50%, which can be used for bio...
