Embodiment 1

[0023] 1. Full-light automatic spraying nursery facilities

[0024] Adopt the all-light spray cutting seedling nursery equipment provided by Beijing Forestry Technology Company of Chinese Academy of Forestry. According to the requirements of the spray device, a circular slotting bed with a diameter of 15m and a height of 25cm was built. In order to ensure the permeability of the slotting bed, a 5cm thick pebble was laid on the bottom and 15cm thick pure river sand was laid as the cutting substrate. Before cutting, use 0.01% potassium permanganate solution and 0.01% phoxim to spray the bed surface for sterilization.

[0025] 2. Cutting preparation and treatment

[0026] In mid-June, select the 8-year-old Qilian Juniper with no disease and insect pests and no mechanical damage in the middle and upper part of the 2nd instar branch as cuttings. After collecting the cuttings, immerse them in clean water in time to prevent water loss; cut cuttings are required to be smooth. , Cut 20cm cu...

Abstract

The invention discloses a Sabina przewalskii quick breeding method to solve a problem of Sabina przewalskii breeding difficulty. The Sabina przewalskii quick breeding method comprises the following steps of (A) preparing cutting slips and processing, (B) cutting and (C) nursing seedlings, wherein in the (B) step, the cutting slips are directly inserted into substrate; full-light atomizing equipment is started to spray a bed surface in an intermitted way, so the cutting slips are tightly combined with the substrate; the cutting slips are atomized by full-light atomizing cuttage seedling-nursing equipment every day after cuttage; by the last ten-day of October, when nursery stocks stop growing, the bed is exchanged for Sabina przewalskii seedlings nursing; cuttage survival Sabina przewalskii are transplanted to a nutrition pot; nutrient soil with the thickness of 4 to 5cm is placed in the nutrition pot; seedlings are placed into the nutrition pot and then substrate is placed; the seedlings are lightly lifted up to ensure root to stretch; and at last the seedlings are placed on a seedling bed in a tidy way. Full-light atomizing cuttage seedling nursing technology is employed and a daylight greenhouse plastic nutrition pot is combined for transplantation; a sunshield net is built; scientific management is employed; and transplantation survival rate can reach by more than 90%, so survival rate of Sabina przewalskii cuttage in a dry area is improved.

Description

Technical field [0001] The invention belongs to the forestry field, and specifically relates to a method for breeding Qilian Juniper. Background technique [0002] Qilian Juniper( SabinaPrzewalskii ) Is an endemic tree species in my country, produced in Qinghai, Gansu Hexi Corridor and the south, and the north of Sichuan. Distributed on sunny slopes, semi-sun slopes or semi-shady slopes, resistant to high cold, drought, extremely barren, well-developed roots, evergreen trees, sparse shrubs. Due to its special ecological distribution characteristics and wide adaptability, it has become the main tree species for greening in arid areas. The well-developed root system has good functions of water retention, soil consolidation and water conservation, and can be used as afforestation tree species or grassland protection forest in arid and alpine regions. The canopy is verdant and the stems stand upright, which can be used as landscaping tree species in arid areas in the distribution ...
