Problems solved by technology

Among them, manual cutting is time-consuming and labor-intensive, and will regenerate after cutting; the method of water storage and flooding has been successfully used in the Yangtze River Estuary, but it requires huge investment and will cause great disturbance to the marine ecosystem; chemical drug killing methods such as Spartina alterniflora can be effectively killed by using mulberry grass, but there are uncertainties in the impact on marine ecology and the problem of re-growth after killing; Guangdong Zhuhai successfully controlled Spartina alterniflora by using the fast-growing mangrove plant S. apetalum Grass, but because of the risk of ecological invasion because of the alien tree species introduced from Bangladesh, it is impossible to promote it on a large scale
Therefore, a safe, effective and durable method for controlling Spartina alterniflora has been lacking so far

Embodiment 1

[0025] This example is used to illustrate the method for controlling Spartina alterniflora provided by the present invention.

[0026] (1) Turn the root:

[0027] In May, use a common sickle to cut off the aboveground part of Spartina alterniflora with a stubble height of 5cm, use a hoe to dig out the underground root system to a depth of 30cm, and bury the aboveground part of the root system of Spartina alterniflora to 20cm or less in the silt by foot. .

[0028] (2) Planting mangroves:

[0029] The hypocotyl (about 25cm long) was inserted into the area after the root was turned. The depth of the hypocotyl was controlled at 1 / 3 of the total length of the hypocotyl, and the planting density of the hypocotyl was 1800 roots / mu. After half a year, Spartina alterniflora almost did not appear under the autumn eggplant tree.

Embodiment 2

[0031] This example is used to illustrate the method for controlling Spartina alterniflora provided by the present invention.

[0032] (1) Turn the root:

[0033] In May, use a common sickle to cut off the aboveground part of Spartina alterniflora, leaving a stubble height of 3cm, dig out the underground root system with a hoe to a depth of 20cm, and bury the aboveground part of the root system of Spartina alterniflora by foot to 20cm or less in the silt. .

[0034] (2) Planting mangroves:

[0035] The tung flower tree bag seedlings were planted in the area after the roots were turned, and the planting density of the tung flower tree bag seedlings was 1500 plants / mu. After half a year, Spartina alterniflora basically did not appear under the tung flower tree.

Embodiment 3

[0037] This example is used to illustrate the method for controlling Spartina alterniflora provided by the present invention.

[0038] (1) Turn the root:

[0039] In April, use a common sickle to cut off the aboveground part of Spartina alterniflora, leaving a stubble height of 8cm, dig out the underground root system with a hoe to a depth of 40cm, and bury the aboveground part of the root system of Spartina alterniflora with a foot to 20cm or less in the silt. .

[0040] (2) Planting mangroves:

[0041]The red sea olive bag seedlings were inserted into the area after the roots were turned, and the planting density of the red sea olive bag seedlings was 1200 plants / mu. Half a year later, Spartina alterniflora almost did not appear under the red sea olive.

Abstract

The invention relates to the field of forestry, and discloses a method for controlling Spartina alterniflora. The method includes: (1) root turning: cutting off the aboveground part of Spartina alterniflora, leaving stubble at a height of 3-8cm, and removing Spartina alterniflora The upper part is buried in the silt; (2) planting mangroves: plant mangrove seedlings at a density of not less than 1000 plants / mu in the area after rooting. The invention can effectively inhibit the regeneration of Spartina alterniflora through the synergistic effect of specific root turning technology and ultra-high-density afforestation mode. Using the method provided by the present invention to control Spartina alterniflora, because the native plant mangrove is used to replace Spartina alterniflora, there is no ecological risk, and the biggest defect of the existing Spartina alterniflora control technology - Spartina alterniflora The problem of intrusion again.

Description

technical field [0001] The invention belongs to the field of forestry, and in particular relates to a method for controlling Spartina alterniflora. Background technique [0002] Spartina alterniflora, which was introduced from the United States in 1979, has erupted in large areas on the coast of my country. In 2003, it was included in the first list of invasive alien organisms by the State Environmental Protection Administration (now the Ministry of Environmental Protection). Spartina alterniflora has strong adaptability, strong reproductive ability, and rapid spread, and its ecological niche overlaps with mangroves, which has caused serious threats to mangroves in Zhejiang, Fujian, Guangdong and Guangxi in my country. [0003] For the control of Spartina alterniflora, there are currently many methods, mainly including: manual cutting method, flooding method, chemical killing method and plant replacement method. Among them, manual excision is time-consuming and labor-intens...
