Abstract

The embodiment of the present invention discloses a cutting rapid propagation method of European spruce, including: cutting bed design: digging deep into the soil to form a cutting pool with a depth of not less than 20 cm; filling the base layer at the bottom of the cutting pool, and After laying the spray pipe group on the surface of the base layer, fill the cultivation layer on the base layer until the cultivation layer completely covers the spray pipe group, and then set up a plurality of grooves on the cultivation layer, and set each groove separately. Along the infiltration tube moving up and down, construct a cutting bed; selection and pretreatment of cuttings: cut annual branches with a length of not less than 6cm as cuttings, soak the cuttings in No. 1 rooting powder and take them out. Obtaining the treated cuttings; cutting cuttings: placing the treated cuttings in a nutrient bag filled with nutrient soil and transplanting them into a cutting bed, controlling the temperature and humidity of the cutting environment for cultivation. The effect of reducing labor costs, improving controllability, and ensuring effective improvement of its survival rate and growth performance is realized.

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...
