Grafting method of Juniperus chinensis with high growth rate

Abstract

The invention discloses a grafting method of Juniperus chinensis with high growth rate. The method comprises the following steps: picking scions on site, wrapping and storing the scions, selecting rootstocks and sand beds, opening the rootstocks, grafting and treating, managing after grafting, erasing rootstock sprouts, sterilizing and fertilizing. According to the method, juniperus formosana withbranches growing in place in a transition mode is selected as a stock, Juniperus chinensis branches growing robustly are selected as scions, the congenital condition is good, a good nutritional environment is provided through cooperation with sand bed with leaf mold, river sand and topdressing, and meanwhile during grafting, the ends of the scions are rapidly inserted between the bark and xylem of a stock notch and aligned with a cambium on one side, at the nutrition supply position, the special growth solution is cooperatively sprayed, so that grafting survival rate is increased; in addition, after grafting, water supply is kept, shading protection is achieved, humidity is guaranteed, sunburn is avoided, sprouts, close to the scion position, of the rootstock are smeared while coming out,sufficient nutrient supply of the scion is guaranteed, and the growth rate is further increased.

Description

Technical field [0001] The invention relates to the technical field of true cypress grafting, in particular to a method for grafting true cypress with high growth rate. Background technique [0002] True cypress, genus Cypress, creeping shrub, up to 150 cm tall, with a crown width of about 100-120 cm, branches extending upwards from the ground, brown-green, densely growing branchlets, branch tips and branchlets upward obliquely; thorn-shaped three-leaf cross-wheel Raw, strip-lanceolate, apex becomes horny and sharp, concave on the top, there are two white powder stomatal bands, stomatal bands often converge in the upper part, the green midrib is only obvious in the lower part, not reaching the tip of the leaf, the lower part is convex, Blue-green, with thin longitudinal grooves along the midrib. Cones are nearly spherical, white powdered, black when mature; [0003] The true cypress is evergreen in all seasons, the tree is beautiful, the lateral roots are developed, the branches ...

AI Technical Summary

Problems solved by technology

[0003] True cypress is evergreen in all seasons, has a beautiful tree posture, well-developed lateral roots, and soft and easy-to-shape branches. The old pile of cypress is grafted with real cypress on it. In the prior art, common grafting techniques are usually used, and the survival rate of grafting is low and the growth is slow. Therefore, the present invention proposes a method for grafting real cypress with a high growth rate to solve the existing problems in technology
