Abstract

An embodiment of the invention discloses a cutting rapid propagation method of European spruce. The method comprises the steps of designing a cutting bed, specifically, carrying out deep digging on soil to form a cutting pool with the depth not smaller than 20 cm; filling the bottom of the cutting pool with a base layer, laying a spraying pipe set on the surface of the base layer, then filling thebase layer with a cultivation layer till the cultivation layer completely covers the spraying pipe set, forming a plurality of ditches in the cultivation layer, arranging an infiltration pipe capableof moving up and down in each ditch, and constructing and forming the cutting bed; selecting and pretreating cuttings, specifically, cutting annual branches with the length not smaller than 6 cm to serve as the cuttings, placing the cuttings in rooting powder I to be soaked and then taking out the cuttings to obtain the treated cuttings; and conducting cutting on the cuttings, specifically, placing the treated cuttings in a nutrient bag containing nutrient soil and transplanted the cuttings into the cutting bed, and controlling the temperature and humidity of the cutting environment for cultivation. The effects of reducing the labor cost, improving the controllability and ensuring effective improvement of the survival rate and growth performance are achieved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of cuttings, in particular to a method for rapid propagation of European spruce cuttings. Background technique [0002] European spruce (Picea abies) is native to northern and central Europe. Because of its fast growth, straight stem shape, strong cold resistance, and strong adaptability, it has become one of the main afforestation tree species in the local area. Picea spruce has a tall tree shape, dense branches, and beautiful tree posture. The needles remain bright green even in severe winters. It has high ornamental value and has broad application prospects in my country. [0003] However, due to the slow growth and late fruiting of Picea spruce seedlings in the early stage, genetic differentiation is prone to occur in seed propagation, which is far from meeting the needs of seedlings for afforestation and urban greening. The use of cutting seedlings can shorten the breeding cycl...
