Description
Technical Field
The invention belongs to the technical field of ecological environment protection, and particularly relates to a method for removing spartina alterniflora from a tidal flat forestation land of a Kandelia candel mangrove forest.
Background
Spartina altermiflora (Spartina altermiflora) is native to North American Atlantic coast, and is a perennial gramineae grown on intertidal zone mudflat. The introduction of Nanjing university (used as a plant for protecting the bank) from the United states in 1979 succeeded in the trial in Jiangsu, and Fujian was introduced in 1980, and the introduction was expanded to Jiangsu, Guangdong, Guangxi, Zhejiang and Shandong provinces in 1982. Because the mangrove forest ecological system has wide adaptability, strong stress resistance, high propagation speed and lack of natural enemies, the mangrove forest ecological system is declined because the mangrove forest ecological system is bred and spread in various places in the country and on the coast quickly, the environment, biodiversity, aquaculture industry and the like cause serious damage, and a plurality of places invade the original mangrove forest area in a large scale, 16 first foreign invader lists in China are listed in 2003. In recent years, in order to control the invasion of the spartina alterniflora, the spartina alterniflora is controlled by adopting methods such as chemical prevention and control, physical prevention and control, biological prevention and control and the like in sequence, but the effect is not ideal, mainly comprising the steps of controlling the spartina alterniflora by a physical method, and having low efficiency, high cost and difficult eradication; the chemical method is easy to bring environmental pollution; biological control methods using natural enemy animals may present ecological risks.
The intertidal zone in the intertidal zone of the Zhejiang coastal area is occupied by the external invasive species of spartina alterniflora, the spartina alterniflora is a C4 plant, the growth is vigorous, and the intertidal zone local plant growing on the spartina alterniflora basically cannot grow. The high growth amount of the Kandelia candel is not more than 40cm in Kandelia, the height of the Spartina alterniflora is 2m, and 100% of Kandelia seedlings in the Spartina alterniflora field die naturally because the Kandelia alterniflora seedlings cannot be illuminated. Therefore, an effective method for thoroughly removing spartina alterniflora in mangrove forestation is urgently needed to be found so as to realize the reconstruction of the Kandelia candel mangrove forest.
Disclosure of Invention
In order to solve the problems, the invention provides a method for removing the spartina alterniflora in the mudflat forestation of the Kandelia candel, which is more practical, effective, lower in dosage and more environment-friendly, can completely remove the spartina alterniflora at one time, has instant effect, and realizes the large-scale reconstruction of the Kandelia alterniflora mangrove in the coastal zone of Zhejiang.
The invention provides a method for removing spartina alterniflora, which adopts a mixture of haloxyfop-methyl and diesel oil to spray spartina alterniflora.
A large number of field experiments for many years prove that the diesel oil has obvious synergistic effect on the haloxyfop-R-methyl, can also obviously reduce the dosage of the haloxyfop-methyl and is beneficial to environmental protection.
Further, the haloxyfop-R-methyl is haloxyfop-methyl tall oil. Of course, other various formulations of haloxyfop-R-methyl may be selected, and oil slick is preferred.
Furthermore, the application amount of the haloxyfop-R-methyl oil and the diesel oil is 30-150 ml of haloxyfop-R-methyl oil, 10-50 g of diesel oil and 15-30 kg of water per mu of land; the content of the effective components of the haloxyfop-R-methyl oil is 108 g/l.
Further, the application amount of the haloxyfop-R-methyl oil and the diesel oil is that 90ml of haloxyfop-R-methyl oil, 25g of diesel oil and 15kg of water are applied to each mu of land.
Further, the time for spraying the spartina alterniflora with the mixture of haloxyfop-R-methyl and diesel oil is 4 months.
Furthermore, before the mixture of the haloxyfop-R-methyl and the diesel oil is sprayed, the spartina alterniflora is cut off in 3 months, and when a new stem of the spartina alterniflora is extracted in 4 months, the mixture of the haloxyfop-R-methyl and the diesel oil is sprayed on stems and leaves of the spartina alterniflora.
Further, when the new stalk of spartina alterniflora in month 4 is pulled out, the new stalk of spartina alterniflora in the middle and last ten days of month 4 is pulled out to 30 cm.
Further, the place for removing the spartina alterniflora is a Kandelia mangrove shoal forestation place.
Further, the mixture is a mixture of haloxyfop-R-methyl and diesel.
Further, the place for removing the spartina alterniflora is a Kandelia mangrove shoal forestation place.
Years of practical experience proves that when the spartina alterniflora is cut off in 3 months and the new stalk of the spartina alterniflora is drawn to 30cm in the middle and last days of 4 months, the stem and leaf of the spartina alterniflora are sprayed with the mixture of the high-efficiency haloxyfop-methyl and the diesel oil, 90ml of high-efficiency haloxyfop-methyl floating oil plus 25g of diesel oil plus 15kg of water is applied to each mu of land, the spartina alterniflora can be permanently removed at one time, the effect is very obvious, no adverse effect on the environment is found, and the Kandelia candel mangrove forest is revived. At present, the technology becomes a core technology for clearing spartina alterniflora from mangrove forest forestation land to realize forestation survival and really realizes the large-scale reconstruction of the mangrove forest of Kandelia candel on the coastal beach of Zhejiang.
The invention has the beneficial effects that: the invention provides a method for removing spartina alterniflora from a kandelia rosea beach afforestation land, which is more practical, effective, lower in dosage and more environment-friendly, the stem and the leaf of the spartina alterniflora are sprayed by adopting a mixture of efficient haloxyfop and diesel oil, the spartina alterniflora in the afforestation land is cut off in 3 months, and the spartina alterniflora is sprayed when a new stem of the spartina alterniflora is extracted to 30cm in the middle and the last ten days of 4 months, so that the spartina alterniflora can be thoroughly removed at one time, the effect is instant, and the wide-range reconstruction of the kandelia rosea in the coastal area of Zhejiang.
