Problems solved by technology

The physical control method is to dig out manually or mechanically. This control method consumes a lot of manpower and material resources. At the same time, the removal is not thorough enough, and it needs to be pulled out year after year.
Chinese patent document CN101228865 discloses a "method for inactivating the alien invasive plant Asteroides spinosa based on the utilization of energy components", which is to pile up the plucked Asteroides spinosa, preheat and dry them in a preheating furnace, and put them into a boiler as biological The fuel is exhausted and turned into ash. This method cannot remove the root system of A. chinensis.
The chemical control method is to use herbicides to eliminate, but there is a problem of secondary pollution, s

Embodiment 1

[0033] Carry out the control method of the growth of Alternatus chinensis of the present invention with an experimental river section, this river section is located at Nanhui District, Shanghai City, and the experimental river section is about 200m long, and the channel section is a double inverted trapezoid, and the channel sectional area is about 100 square meters, often The water level channel is about 40m wide, and at normal water level, the maximum water depth is 3.6 meters, and the water transparency is about 50cm. Before the implementation of the method for controlling the growth of the three-dimensional plants of the three-dimensional plant of the hollow lotus plant, the hollow lotus plant in the river channel grows fiercely, and the coverage rate is as high as 40%. From December of the current year to March of the next year, remove the Alpinia sinensis on the bank of the river by manual mowing, and remove the provenance: dig out the 50cm-deep sediment with the rhizome ...

Embodiment 2

[0044] The implementation object of this embodiment is a river entering the lake in a certain Nansi Lake in Jining City, Shandong Province. The experimental river section is about 150m long, about 50m wide, and the water transparency is about 35cm.

[0045] In December of that year, remove the Nepterophyllum spinosa on the bank of the river by manual mowing, and remove the provenance: dig out the sediment with the rhizome of the Neptonia spinosa about 45cm deep on the river bank, and use tools such as shovels to remove the The rhizomes of the hollow lotus in the sediment are chopped.

[0046] From March of the next year, select 9,000 well-developed reed rhizomes, about 5 as a clump, and 4 clumps / m 2 The density of reeds was planted on both sides of the river, and the planting width of the reed group was about 1.5m on each side, and the total length along the experimental river section was 150m.

[0047] From mid-March of the following year, emergent plant belts, floating leaf...

Abstract

The invention provides a method for controlling the growth of alligator alternanthera, which is characterized by comprising the steps of: removing alligator alternanthera at the riverway shoreside with a physical method, then constructing a riverway riparian zone reed group, and sequentially constructing an aquatic plant group from two sides of the riverway shoreside to the riverway center direction. The method for controlling the growth of the alligator alternanthera, replaced with three-dimensional plants, has the advantages of low investment, environment friendless, higher practical value and wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of ecological control, and in particular relates to a method for controlling the growth of Alpinia sinensis with three-dimensional plants instead. Background technique [0002] Alternanthera philoxeroides (Alternanthera philoxeroides), commonly known as water peanut, belongs to the genus Amaranthaceae. It is native to South America and is currently distributed in all continents. It is one of the world-recognized malignant weeds. Among the two important invasive species, A. chinensis ranks among the top three. During the Japanese invasion of China, it was introduced by the Japanese to the suburbs of Shanghai as horse feed, and later became wild; in the 1950s, Jiangsu, Zhejiang, Shanghai and other provinces and cities gradually promoted it as pig and sheep feed; Southern provinces; Introduced to Hebei, Beijing, Shandong, Liaoning and other provinces north of the Yangtze River in the 1970s; Recently, some rive...
