Problems solved by technology

[0004] In the application of the above technologies, at least there are: long seedling breeding cycle, difficult rooting of cutting seedlings, low survival rate, only about 40-50%, high seedling cost, relatively small reproduction coefficient, and it is difficult to meet the requirements of modern afforestation and urban landscaping. need

specific Embodiment approach

[0016] The preferred specific embodiment of the present invention is as follows:

[0017] A kind of cutting breeding method of Cypress stipitis, the method comprises the steps

[0018] ①Renovation of cutting bed: firstly, after deep digging the seedling tray to remove impurities, apply basal fertilizer, and level it, make a low bed with a width of 1.8m, a length of 1.5m and a depth of 20cm; spread clean river sand on the seedbed, and the sand bed is 5 cm thick. ~10cm; disinfect with 800-1000 times carbendazim liquid;

[0019] ②Picking: Choose 1-2 year old branches with strong growth and no pests and diseases when collecting, with a length of 20-30cm, and put the cut branches into a plastic bucket filled with clean water to prevent water loss and drying up; picking should be carried out in the early morning. ;

[0020] ③ Processing of cuttings:

[0021] a: Cut the collected branches into 15-20cm cuttings, keep the needles, and cut the mouth in a horseshoe shape. It is requir...

Abstract

A cuttage and breeding method for sabina vulgalis comprises the steps of renovating a cuttage bed, picking branches, processing shoot for cutting, performing cuttage and the like; deeply ploughing a seedling tray, clearing off impurities, applying cottage, leveling, widening to make a lower bed, and paving clean river sand on the seedling bed; sterilizing the sand bed which is 5-10cm thick with 800-1000 times of carbendazol liquid medicine; picking 1-2 years old healthy and strong branches without diseases or pests at dawn, putting the branches cut down in a plastic cask constraining water timely to prevent drying-up due to water loss; processing shoot for cutting by adopting different medicines and plant growing hormone with concentration being 50-150ppm for dipping for 2-6h, so that breeding coefficient is higher. Facts prove that the cuttage and breeding survival rate of sabina vulgalis bred by using the invention can reach up to 75-89%, thus realizing the aim of enhancing breeding coefficient.

Description

technical field [0001] The invention relates to a method for raising seedlings, in particular to a method for cutting and breeding a hard-to-root conifer, that is, Cypress serrata. Background technique [0002] Sabina vulgaris Ant., also known as Fork Juniper, Xinjiang Juniper, is an evergreen creeping shrub of the Cypress family. It is produced in Xinjiang Tianshan to Altai Mountains, Ningxia, Inner Mongolia, northeastern Qinghai, the northern slope of Qilian Mountains in Gansu, and Yulin in Shaanxi, with an altitude of 1100-3200m in rocky mountains and dunes. Beijing, Xi'an and other places have introduced species. Creeping shrubs, less than 1m tall; branches dense, spreading obliquely, branchlets thin, about 1mm in diameter, nearly round. The scale leaves are cross-opposed and close to each other, the apex is obtuse or slightly acuminate, and there are obvious oval glands in the middle of the back; thorn-shaped leaves are often born on young trees, dioecious; the cones ...
