specific Embodiment 1

[0028] 1. Seed selection and preservation: select the marsh willow community with a growth cycle of 3 years under natural environmental conditions as the collection site, cut each marsh willow to 1 / 3 of the height, and cut no more than 4 plants per square meter. Select the branches of Marix willow with a thickness greater than 0.5cm, cut the clipped plants of Marix willow into 9cm cuttings, ensure that there are 3 to 5 buds on each cutting, and fully wrap the cuttings with a damp cloth with good air permeability. Store in an environment with a temperature of 4-6°C for 5 days, and use an air-pressure watering spray bottle to spray water to keep the humidity at 90%.

[0029] 2. Site selection: From April to May, in the inland degraded salt marsh wetland, select a more severely degraded area to build a small restoration pond with a length × width × height of 6m × 4m × 0.4m, and use a flat spade to The bottom of the cuvette is compacted and kept flat.

[0035] 1. Seed selection and preservation: select the marsh willow community with a growth cycle of 4 years under natural environmental conditions as the collection site, cut each marsh willow to 1 / 3 of the height, and cut no more than 4 plants per square meter. Select the branches of Marix willow with a thickness greater than 0.5cm, cut the clipped plants of Marix willow into 12cm cuttings, ensure that there are 3 to 5 buds on each cutting, and fully wrap the cuttings with a damp cloth with good air permeability. Store in an environment with a temperature of 4-6°C for 8 days, and use an air-pressure watering spray bottle to spray water to keep the humidity at 100%.

[0036] 2. Site selection: From May to June, in the inland degraded salt marsh wetland, select a more severely degraded area to build a small restoration pond with a length × width × height of 4m × 2m × 0.25m, and use a flat spade to The bottom of the cuvette is compacted and kept flat.

[0042] 1. Seed selection and preservation: select the marsh willow community with a growth cycle of 4 years under natural environmental conditions as the collection site, cut each marsh willow to 1 / 3 of the height, and cut no more than 4 plants per square meter. Select the branches of Marix willow with a thickness greater than 0.5cm, cut the clipped plants of Marix willow into 10cm cuttings, ensure that there are 3 to 5 buds on each cutting, and fully wrap the cuttings with a damp cloth with good air permeability. Store in an environment with a temperature of 4-6°C for 6 days, and use an air-pressure watering spray bottle to spray water to keep the humidity at 95%.

[0043] 2. Site selection: In May, in the inland degraded salt marsh wetland, select a more seriously degraded area, build a small recovery pond with a length x width x height of 4m x 2m x 0.25m, press the bottom of the small pool with a flat shovel firm and level.

Abstract

The invention relates to a potted plant technique based efficient breeding method for salix brachypoda cutting in degraded inland saline marsh wetlands with an aim to mainly solve problems the salix brachypoda cutting in the degraded inland saline marsh wetland is low in survival rate and slow in restoration. The method specifically includes the steps of 1), seed selection and storage; 2), land selection; 3), soil unloading and potting; 4), cutting; 5), hydrologic management; 6), transplantation. The method has the advantages that raw materials are easy to obtain, cost is low, operation is simple and easy to implement, and centralized management is facilitated; ecological laws are obeyed, and environmental adaptabilities of wetland plants are fully considered; restoration of an inland saline-alkali marsh wetland ecosystem is benefited; the survival rate of salix brachypoda can reach more than 97%, and biodiversity of wetlands is increased.

Description

technical field [0001] The invention relates to the field of ecological environment protection, in particular to a high-efficiency propagation method of marsh willow cuttings in inland degraded salt marsh wetlands based on pot planting technology. Background technique [0002] Wetland is a special natural complex formed by the interaction of water and land. Because of its huge hydrological and element cycle functions, it is called the "kidney of the earth". It is also one of the most productive ecosystems in nature. It plays an important role in controlling soil erosion and degrading environmental pollution. In recent years, due to insufficient understanding of wetland protection and improper human activities, the ecological environment of wetlands has been increasingly damaged. The area of ​​wetlands has gradually decreased, production and ecological functions have declined rapidly, and wetlands have been seriously degraded. The research on restoration and restoration tech...
