specific Embodiment approach 1

[0019] Specific embodiment one: present embodiment is a kind of reed seedling optimal transplanting density and the acquisition method of initial planting height, specifically is finished according to the following steps:

[0020] 1. Collection of reed rhizomes in the wild: In late April, dig out rhizomes through small patches, dig up to the extension of horizontal rhizomes, dig out rhizomes, put them into black plastic bags, and Spray water to keep the surface of the rhizome moist to obtain the rhizome to be raised;

[0021] 2. Indoor seedling cultivation: wash and remove the soil on the surface of the rhizomes to be raised, and then spread it on the surface of the sand. The depth of the sand is 48cm to 52cm. Then use river sand to cover and bury the rhizomes to be raised, and spray water until the water content of the sand reaches 85% to 100%, and then grow seedlings at an indoor temperature of 25±3°C;

[0022] 3. Seedling cultivation: 4 seedling height gradients are set wi...

specific Embodiment approach 2

[0025] Embodiment 2: The difference between this embodiment and Embodiment 1 is: in step 1, the rhizomes are excavated through small plaques, and the rhizomes are excavated at a depth of 20 cm to 30 cm. Others are the same as the first embodiment.

specific Embodiment approach 3

[0026] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: in step 2, river sand is used to cover and bury the rhizomes to be raised, and the thickness of river sand covering is 2cm. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a method for obtaining optimal transplanting density and initial planting height of a reed seedling, and relates to the technical field of ecological restoration. The method isused for restoring rapidly the vegetation in the degraded saline-alkali wetlands. The method aims at solving the problems of low survival rate and slow seedling growth of the reed in the degraded reed wetlands. The method includes the following steps of first, collection of reed root-like stem; second, indoor seedling; third, seedling cultivation at different seedling heights and different plantdensities; fourth, measurement and settlement; fifth, analysis of optimal transplanting density and initial planting height. The method has the advantages that the cost and the cycle of the seedling transplanting are reduced, the plant height and the biomass accumulation of the reed seedlings are increased, and the high relative growth rate is maintained, so that the rapid restoration of the reedwetlands is facilitated. The method is mainly used for obtaining the optimal transplanting density and the initial planting height of the reed seedlings.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and relates to a method for quickly restoring vegetation in degraded saline-alkali wetlands, in particular to a method for obtaining the optimum transplanting density and initial planting height of reed seedlings. Background technique [0002] Phragmites reed is the main construction species of emergent plant communities in wetlands. It not only widely grows in freshwater swamps, but also in coastal wetlands and inland saline-alkali wetlands with high salinity. Reed swamps are also one of the main types of herbaceous swamps in my country. In addition to a wide range of environmental adaptability, reed populations can quickly colonize, grow and expand, and thus become a key tool species for wetland ecological restoration. In addition, reed plays a very important role in the protection of wetland biodiversity, the function of wetland ecosystem and the maintenance of ecological balanc...
