Description

Method for preventing and controlling enteromorpha harm in mangrove
Technical Field
The invention belongs to the technical field of mangrove plant pest control, and particularly relates to a method for controlling the damage of mangrove enteromorpha.
Background
Enteromorpha is a common seaweed in coastal areas, is generally commonly called as Enteromorpha green seaweed, and belongs to the phylum Chlorophyta, class Chlorophyta, dan meshes and Danke in classification. Enteromorpha is a worldwide wide-temperature species, the distribution range of the Enteromorpha extends from the vicinity of the equator to the polar region, the natural environment adaptability of the Enteromorpha is strong, and the Enteromorpha is distributed from the estuary with low salinity to the salt pan with high salinity.
As the propagation speed of the Ji sedge is extremely high, the biomass can be rapidly increased in a short time, so that inorganic nutritive salts in water are rapidly reduced and even completely exhausted, and then the algae are largely dead, rotten and deteriorated, and the water quality is abnormally deteriorated.
Enteromorpha can cause serious harm to natural forest and artificial forest of mangrove. In the outbreak period of the enteromorpha, a large amount of enteromorpha covers the aerial roots of the mangrove and the mangrove soil, so that the aerial roots of the mangrove and the normal gas exchange of the mangrove soil are blocked, meanwhile, the enteromorpha is easy to cause poor water accumulation on the beach surface, benthonic animals in the soil die, the anoxic condition of the root system of the mangrove is further worsened, and in the natural extinction period of the enteromorpha, the enteromorpha dies and decays in a large amount, and serious hypoxia of the mangrove soil is often caused, so that the natural mangrove in a piece is dead; for low artificial mangrove plants, enteromorpha can even cover the whole plant, resulting in a large number of lodging injuries and deaths of the plant. Therefore, a safe and effective control method is required aiming at the harm of the enteromorpha, so that the enteromorpha can be effectively removed, and no new harm is generated to the mangrove.
Disclosure of Invention
In order to solve the technical problems, the invention provides a method for preventing and controlling the harm of enteromorpha in mangrove forests, which is characterized in that the harm of enteromorpha to the mangrove forests is prevented and controlled by various technical means such as spraying acetic acid liquid medicine, releasing natural enemies, transplanting competition plants of gracilaria and the like.
In order to achieve the above purpose, the invention provides the following technical scheme,
a method for preventing and controlling the damage of the enteromorpha in the mangrove forest comprises spraying acetic acid liquid medicine on the land of the beach of the mangrove forest covered or surrounded by the enteromorpha, so as to kill the enteromorpha in the mangrove forest; the concentration of the acetic acid liquid medicine is 2.5% -10%.
The specific operation is as follows: (1) Usually, the spraying time of the acetic acid liquid medicine is carried out on sunny days without rainfall after the tide is removed, after the enteromorpha in the mangrove is exposed out of the beach surface and no obvious ponding exists on the enteromorpha, the enteromorpha prevention and treatment operation is started, and if the beach surface water exists at the position of the enteromorpha, a ditch is dug to remove the ponding completely, and then the enteromorpha prevention and treatment operation is carried out.
(2) The acetic acid liquid medicine spraying method comprises the following steps: uniformly spraying with acetic acid solution 3-4m per liter perpendicular to enteromorpha growth direction 2 Is enteromorpha prolifera of (a).
(3) Checking the spraying effect of the liquid medicine: the enteromorpha can be changed from the green surviving into the dead white within 3-4 hours after spraying, and the enteromorpha community in a piece can be scoured by seawater for busy due to structural disruption after 2-3 days.
(4) Liquid medicine spraying frequency: at the end of 9 months of each year to the 5 months of the second year, the enteromorpha can be sprayed 1 time per month on the mangrove beach with less enteromorpha, and can be sprayed 1-2 times per month on the mangrove beach with more enteromorpha.
Further, the mangrove beach with less enteromorpha is the beach area of mangrove with the thickness of enteromorpha being less than or equal to 1cm or the area of enteromorpha being less than or equal to 50%; the mangrove beach with more enteromorpha is the beach area of the mangrove with the thickness of the enteromorpha being more than 1cm or the area of the enteromorpha being more than 50%.
Further, 2.5% acetic acid solution is used when the enteromorpha covered on the beach is less, and 10% acetic acid solution is used when the enteromorpha covered on the beach is thicker.
Further, the method for preventing and controlling the damage of the enteromorpha in the mangrove forest further comprises a natural enemy prevention and control means, and the method for feeding enteromorpha in a way of feeding and taking out the enteromorpha in the way of spraying acetic acid liquid medicine for 7 days. The putting quantity of the stone sulfo is 10-20/m 2 . The stone sulfonic is usually harvested once for about 3 months. The stone sulfonic acid is less affected by acetic acid because of low concentrationAcetic acid is added after the acetic acid liquid medicine is sprayed for 7 days, and the residual acetic acid amount in mangrove is very small along with the scouring of seawater, so that the effect on the stone sulfonic acid is almost avoided.
Further, the prevention and treatment of the damage of the mangrove enteromorpha further comprises the step of transplanting enteromorpha competition plants, wherein the enteromorpha competition plants are gracilaria.
Further, the gracilaria seedling algae are sown or planted on the beach surface for cultivation; the gracilaria transplanting time is that after the liquid medicine is sprayed for 4-5 days, gracilaria seedlings can emerge after reaching 6-7cm long for transplanting.
Gracilaria is sown and cultivated, wherein gracilaria seedlings and a growth medium are regularly spread on a beach surface according to specifications to form vegetable furrow-type arrangement, the distance between furrows is 2.0m, and the distance between the growth medium is 40cm. The gracilaria seedling is clamped in a seedling clamping ditch formed in advance by bamboo sticks, and then the bamboo sticks are cut on a beach, wherein the cutting line spacing is 50-60cm, and the plant spacing is 30-35cm; the sowing or inserting time is carried out after the tide is refunded and the mud flat surface is leaked.
Further, the gracilaria variety is any one or a mixture of gracilaria tenuifolia branch variety, gracilaria chrysanthemi and gracilaria verrucosa.
Gracilaria algae are usually red, dark purple green or dark brown, and the gracilaria algae are adsorbed on a growth substrate for growth, wherein the basal part of the gracilaria algae is a disk-shaped fixer. The gracilaria is strong in growth force, and 10 months to 2 months of the next year are the most suitable growth time of the gracilaria, and gracilaria is planted at the moment, so that the algae grow rapidly, and the gracilaria can be the best competitor of enteromorpha. The gracilaria can be harvested after growing for 3-5 months, thereby obtaining economic value. The method not only suppresses the growth of the enteromorpha and but also can carry out economic algae cultivation.
The gracilaria and the enteromorpha have a competitive relationship in terms of living space and resource utilization, and compared with the gracilaria, the enteromorpha is hydrophobic, so that the gracilaria has a competitive advantage under the condition that the gracilaria and the enteromorpha coexist. Moreover, the gracilaria is not easy to cause water accumulation on the beach surface, can grow all year round and is not easy to rot, thereby causing adverse effects on the beach environment, and therefore, the growth form of the gracilaria has less negative effects on the coverage of aerial roots. The enteromorpha belongs to the type of full beach coating cover, has large water absorption, is particularly easy to cause local ponding on the beach, and causes root rot of mangrove seedlings, thereby causing forestation failure.
Compared with the prior art, the invention has the following beneficial effects:
1. the method provided by the invention adopts an acetic acid agent spraying method, can effectively prevent and control the growth of enteromorpha, is convenient to operate, takes effect quickly, has a good control effect, can see effect in a short period, has small influence on the environment, and does not influence the growth of mangrove.
2. According to the method, the prevention and treatment means of natural enemies of the enteromorpha are combined, the stone sulfo is put in to take the enteromorpha as food, the enteromorpha left after acetic acid treatment is controlled, meanwhile, the stone sulfo is put in after acetic acid agent is sprayed for 7 days, and the stone sulfo is put in after acetic acid is sufficiently diluted, so that the stone sulfo cannot be influenced.
3. The method also combines the control means of enteromorpha competition plants, and makes the gracilaria and the enteromorpha compete for living space to inhibit the growth of the enteromorpha by the technical means of transplanting the gracilaria, and simultaneously improves the output of additional economic value of coastal beaches.
