specific Embodiment approach 1

[0015] Specific implementation mode one: a method for effectively controlling and restoring wetland annual weeds in this embodiment is specifically carried out according to the following steps:

[0016] 1. Field investigation: In the same wetland area where the annual weeds invaded the wetland to be restored, investigate the target population and the suitable water level and plant phenology of the annual weeds;

[0017] 2. Restoration area arrangement: For the wetlands to be restored invaded by annual weeds, the water level of the wetlands to be restored invaded by annual weeds can be adjusted by means of dam building and water diversion, and a wet area with controllable water level can be obtained;

[0018] 3. Seedling monitoring and flood treatment: In the wet area with controllable water level obtained in step 2, observe the germination of annual weed seeds and the growth of seedlings. When the height of annual weed seedlings is 0.1cm to 5cm, refer to the step 1. Obtain the...

specific Embodiment approach 2

[0021] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the target population described in step 1 is one of Cymbidium spp. or several. Others are the same as the first embodiment.

specific Embodiment approach 3

[0022] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the annual weeds described in step 1 are one or more of Polygonum halberds, barnyardgrass, barnyardgrass, crabgrass or bald barnyardgrass. kind. Others are the same as those in Embodiment 1 or 2.

Abstract

A method effectively controlling restored wetland annual weeds can solve the problems that an existing method can inhibit native biology, can easily cause environment pollution, is high in processing cost, and poor in control effect; the novel method comprises the following steps: 1, field investigation; 2, recovery zone sorting; 3, seedling monitoring and flood treatment; 4, plant investigation; 5, seed database monitoring. The novel method can use the flood to eliminate annual weed seedlings without affecting object population growth and multiplication, thus preventing the annual weeds from inhibiting native plants and competing with the native plants, continuously reducing weed seed database scale, and effectively controlling wetland vegetation succession direction; in addition, the novel method is biological and environmental protective, low in cost, and suitable for wetland vegetation recovery practice works.

Description

technical field [0001] The invention relates to a method for effectively controlling and restoring wetland annual weeds. Background technique [0002] All over the world, wetland restoration has become a hot issue of concern from all walks of life (Lv Xianguo, Wetlands and Wetland Research in China, Hebei Science and Technology Press, 2008). However, although some wetlands have been restored for several years or even decades, many natural vegetation (such as sedge and sedge) still do not appear. Restoration and reconstruction of the target population (Kim DH, Kim HT, Kim JG. Effects of water level and soiltype on the survival and growth of Persicaria thunbergii during early growth stages. Ecological Engineering, 2013, 61: 90-93). [0003] At present, measures such as plowing, burning and pesticides are mainly adopted for wetlands seriously invaded by non-target species such as annual weeds. Although these methods control non-target plants to a certain extent, they also inhi...
