specific Embodiment approach 1

[0022] Specific implementation mode 1: This implementation mode is a method for utilizing reed seed germination to restore wetland vegetation, specifically completed according to the following steps:

[0023] 1. Collection and storage of reed seeds: Cut mature and low-hanging reed ears in the reed wetlands in Northeast China in mid-October, dry them in the sun, put them into ventilated woven bags, and put the reed ears The woven bags are stored in a ventilated and dry environment with a temperature of 0°C to 4°C until the next spring sowing;

[0024] Two, the processing of reed seed: take out the reed ear stored before sowing, make reed seed fall off from reed ear again, collect reed seed; then immerse reed seed into the potassium nitrate solution that the mass fraction of potassium nitrate is 0.1% for 8h ~12h, and stir once every 1h~2h, stirring for 1min~2min each time;

[0025] The quality of the reed seed described in step 2 is (150g~200g):1L with the volume ratio of potas...

specific Embodiment approach 2

[0038] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the reed wetland in Northeast China mentioned in Step 1 is Panjin Wetland or Zhalong Wetland. Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0039] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: in step 1, in mid-October, cut mature, low-hanging reed ears in the reed wetland in Northeast China, and dry them in the sun. Then put it into a ventilated woven bag, and then put the woven bag with reed ears into a ventilated and dry environment with a temperature of 4°C for storage until the next spring sowing. Other steps are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a method for recovering wetland vegetation through reed seed germination and relates to a method for recovering wetland vegetation. The method is mainly used for solving the problems that in an existing method for recovering wetland vegetation through reeds, seedlings need to be excavated, transported and planted manually, cost is high, and the death rate is high. The method includes the steps that first, reed seeds are collected and stored; second, the reed seeds are processed; third, the seeds are screened; fourth, the seeds are sown; fifth, the reed seeds germinate. The method has the advantages that the method is easy and convenient to perform and low in cost, and the problems that in the existing method for recovering wetland vegetation through reeds, seedlings need to be excavated, transported and planted manually, cost is high, and the death rate is high are solved; the planting cost of per group is smaller than 0.1RMB, and the method has a remarkable cost advantage; the seed germination time is shortened by 8 days to 10 days compared with seeds which are not processed, and the average germination rate is increased by 26% to 30%. The method for recovering wetland vegetation through reed seed germination can be obtained.

Description

technical field [0001] The invention relates to a method for restoring wetland vegetation. Background technique [0002] Phragmites reed is a perennial herb of the Poaceae Phragmites genus, with thick and creeping rhizomes, and has two propagation methods: seed propagation and branch propagation. The plants of Phragmites reed are tall, with a stem height of up to 3m, a diameter of up to 4cm, and more than 20 nodes; the leaves are flat, up to 45cm in length, up to 3.5cm in width, and thick in quality; the creeping rhizomes are well developed and have strong vitality. , the root zone can reach more than 1m below the surface soil; it mostly grows in rivers, lakes, ponds and ditches and low wetlands, and is widely distributed all over the world. [0003] Reed stalks are hard, fine in texture, and high in fiber content, generally 40% to 60%, and are important raw materials for my country's paper industry. The roots of reeds are relatively large, which can absorb heavy metals an...
