specific Embodiment approach 1

[0020] Specific implementation mode 1: The method for replenishing water in this implementation mode to increase the population density of the flat stalk Vitex trigonum includes the following steps:

[0021] 1. Plot selection: Combined with the vegetation survey in the previous year, a typical degraded Vitex trigonum wetland was selected as the wetland to be restored. The selection principle: the surface soil moisture content is 15%-25%, the surface is flat, and Vitex trigonum is the dominant species, The population density of the flat-stalked Vitex trigonum is 200-400 plants / m 2 the land;

[0022] 2. Water source selection: In the wetland to be restored selected in step 1, low-lying blisters are selected as the water source. The pH value of the water in the blisters is 8.9-9.3, and the salinity is 500mg / L-2000mg / L;

[0023] 3. Gridding treatment of wetlands to be restored: in the wetlands to be restored, manually divide the land next to the water source into grid fields, and...

specific Embodiment approach 2

[0032] Embodiment 2: This embodiment differs from Embodiment 1 in that: in step 2, the pH value of the water in the blister is 9.0-9.1. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0033] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the salinity in step 2 is 1000 mg / L-1500 mg / L. Others are the same as in the first or second embodiment.

Abstract

The invention discloses to a moisturizing method for increasing population density of bolboschoenus planiculmis, relates to a moisturizing method of bolboschoenus planiculmis population, and aims at solving the problem of low population density of existing bolboschoenus planiculmis. The method includes the steps of selection of fields, wherein through combination with vegetation investigation last year, a typical degenerated bolboschoenus planiculmis wetland is selected as a wetland to be recovered; selection of a water source, wherein a low-lying pool is selected as the water source; latticing treatment of the wetland to be recovered; manual moisturizing; moisturizing amount, wherein the moisture content of surface soil is remained within 45-55%; observation of vegetation growth. According to the moisturizing method, the emergence rate and survival rate of the bolboschoenus planiculmis population are ensured, moisturizing is conducted periodically and the population density change is monitored, and three weeks after moisturizing, the population density of bolboschoenus planiculmis the moisturizing amount of which is 45-55% soil moisture content is increased by 0.5-2.5 times than other treatment methods. The moisturizing method for increasing the population density of bolboschoenus planiculmis is used for recovery of the bolboschoenus planiculmis population.

Description

technical field [0001] The invention relates to a method for replenishing water for restoring populations of Vitex trigonum flat stalks. Background technique [0002] Bolboschoenus planiculmis is a Cyperaceae plant with a synonym of Bolboschoenus planiculmis. It is a typical plant in the Momoge Wetland in the west of the Songnen Plain. In recent years, due to the superimposed impact of climate change and human activities, the water shortage and salinization of wetlands have intensified, resulting in the reduction of the area of ​​Momoge Vitex trigonum wetlands, the quantity and quality of Vitex trigonum bulbs have declined significantly, and the food sources and habitats of Siberian cranes have been affected. serious threat. In order to protect wetland resources and improve the ecological function of wetlands, Momoge Nature Reserve has carried out artificial vegetation restoration of flat stalks and triangular thorns. Ecological water replenishment is an important part of v...
