specific Embodiment approach 1

[0016] Specific embodiment one: present embodiment is a kind of screening method of reed seedling optimal salt-nitrogen condition, is specifically finished according to the following steps:

[0017] 1. Collection of reed rhizomes: During the germination stage of reed rhizomes, dig out rhizomes through small patches, dig out to the extension of horizontal rhizomes, dig out rhizomes, and put them into black plastic bags , spraying water to keep the rhizome surface moist, to obtain the reed rhizome to be raised;

[0018] 2. Indoor seedling cultivation: wash and remove the soil on the surface of the rhizome of the reed to be raised, and then spread it on the surface of the sand. The depth of the sand is 50cm, and then use the sand to completely cover the rhizome of the reed to be raised. The temperature is controlled at 25 ± 3 Cultivate at ℃, during the cultivation process, ensure that the sandy soil surface is moist by spraying water, and obtain reed seedlings;

[0019] 3. Seedl...

specific Embodiment approach 2

[0021] Specific embodiment two: the difference between this embodiment and specific embodiment one is: during the budding period of reed rhizomes in late April every year, the rhizomes are dug out through small patches, and the roots are dug to the extension of the horizontal rhizomes After digging the rhizomes, put them into a black plastic bag, spray water to keep the surface of the rhizomes moist, and obtain the rhizomes of reeds to be raised. Others are the same as the first embodiment.

specific Embodiment approach 3

[0022] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that in step one, during the budding period of reed rhizomes in late April each year, goose head soaking in Momoge National Nature Reserve, Zhenlai County, Jilin Province In the reed swamp, select the reed seedlings to grow evenly, and dig out the rhizomes through small patches, and dig to the extension of the horizontal rhizomes. After digging the rhizomes, put them into black plastic bags, and spray water. Keep the surface of the rhizome moist to obtain the rhizome of the reed to be raised. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a screening method for optimal salt and nitrogen conditions of reed seedlings, which belongs to the technical field of ecological restoration, and specifically relates to a screening method for optimal salt and nitrogen conditions of reed seedlings in saline-alkali wetlands. The purpose of the invention is to solve the problems of low survival rate of transplanted reeds and slow growth of seedlings in the existing degraded reed wetlands. A screening method for optimal salt and nitrogen conditions for reed seedlings: 1. Collection of reed rhizomes; In the case of nitrogen concentration / nitrogen addition concentration combination, the seedlings were cultivated respectively; 4. Detection and analysis: according to the plant height of reed seedlings, the biomass of aboveground plants of reed seedlings, the biomass of underground rhizomes of reed seedlings, and the total biomass of reed seedlings, SPSS 19.0 was used One-way analysis of variance was carried out, and finally the optimal salt and nitrogen conditions for reed seedlings were obtained. Advantages: The survival rate of transplanted reed seedlings reaches 100%. The invention is mainly used for rapid recovery and reconstruction of reeds in saline-alkali wetlands.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and in particular relates to a screening method for optimal salt and nitrogen conditions of reed seedlings in saline-alkali wetlands. 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. 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 balance. [0003] Reed has a wide range of economic value: 1. The crude protein content in the vegetative growth period is the highest among grasses, and it is an e...
