Problems solved by technology

However, at present, Populus euphratica is mostly propagated by cuttings in the nursery and then transplanted to saline-alkali land. Due to the large difference in the growth environment and soil conditions of the cutting plants, it is difficult for the cutting plants to survive in the saline-alkali land. The survival rate is low, which affects the transplantation and afforestation of Populus euphratica on saline-alkali land

Embodiment 1

[0017] A method for rapid cutting propagation of Populus euphratica in greenhouses in mild saline-alkali land. The cutting propagation method is to use adult healthy branches of Populus euphratica to carry out in February, including steps:

[0018] 1) Plucking strips: adult healthy branches of Populus euphratica, cut into branches with a length of 15cm and a branch diameter of 0.5cm, cut the tip of the flat bud, and cut the lower end of the branch obliquely below the opposite direction of the bud to form the base, and the cut should be smooth;

[0019] 2) Root stimulation: Choose a high-lying saline-alkali land to build a shed after irrigation and infiltration, turn the mild saline-alkali soil in the greenhouse into the whole bed and flat bed, spread a layer of sterilized river sand with a thickness of 3 cm on the bottom of the bed, and put the saline-alkali land in the bed Sprinkle the improved fertilizer at 500kg / mu on the soil, turn over the soil and mix evenly, then tie up ...

Embodiment 2

[0024] The method for rapid cutting propagation of Populus euphratica in greenhouses in mild saline-alkali land is characterized in that the cutting propagation method is carried out in February by using adult healthy branches of Populus euphratica, including steps:

[0025] 1) Picking strips: Take the branches of adult healthy Populus euphratica in February of that year, cut the branches with a length of 20cm and a branch diameter of 1.5cm, cut the flat bud tip, cut the lower end of the branch obliquely below the opposite direction of the bud to form the base, and cut the mouth to be smooth;

[0026] 2) Root stimulation: choose a high-lying saline-alkali land to irrigate and infiltrate to build a shed, plow the mildly saline-alkali soil in the shed to the whole bed and flat the bed, spread a layer of 5 cm thick sterilized river sand on the bottom of the bed, and put the saline-alkali land in the bed The soil is sprayed with 800kg / mu of improved fertilizer, then turned over an...

Abstract

The invention discloses a method for rapid cutting propagation of populus euphratica in a light saline-alkali soil greenhouse. The cutting propagation method is conducted by using branches of adult healthy populus euphratica in February and includes the steps of cutting wood picking, root promoting, bowl breeding and seedling hardening. The branches of the adult healthy populus euphratica guarantee that sufficient nutrients are stored in scion bodies, and root promoting is conducted before cuttage, so that root original bodies exist on root sections during cuttage, and the survival rate of scion cutting propagation is increased; meanwhile, the cutting propagation time of the populus euphratica is greatly shortened, the propagation efficiency is improved, especially branch root promotion and bowl breeding are both conducted in the light saline-alkali soil environment, so that the change difference between the growth environment of saline-alkali soil after cuttage branch propagation andtransplanting and soil growth conditions is small, transplanted cuttage plants can easily survive, the survival rate is high, and the transplanting survival rate is 85% or above.

Description

technical field [0001] The invention relates to a tree propagation technology, in particular to a method for rapid cutting propagation of Populus euphratica in greenhouses in mildly saline-alkali land. Background technique [0002] Populus euphratica has strong adaptability, salt and alkali resistance, cold resistance, early dryness, well-developed root system and strong germination ability. Populus euphratica can be planted on soil with a pH value of 9.3 and a salt content of 1.4759%, and its growth is vigorous. Populus euphratica can not only absorb saline-alkali, but also has special ability to get rid of saline-alkali. Populus euphratica can grow on sulfate soil, chloride saline soil and soda saline soil. It is a promising tree species for afforestation on saline-alkali soil. However, at present, Populus euphratica is mostly propagated by cuttings in the nursery and then transplanted to saline-alkali land. Due to the large difference in the growth environment and soil c...
