Description

Method for planting mangrove forest in rubble area of culture pond
Technical Field
The invention relates to the technical field of mangrove forest planting, transplanting and repairing, in particular to a method for planting mangroves in a rubble area of a culture pond.
Background
Mangrove is a green plant community growing on tropical and subtropical beaches, and is a special forest ecosystem transitioning from land to ocean. The mangrove is the only woody plant living in the coastal wetland ecosystem, and has important significance in wind prevention, wave elimination, bank protection promotion, biological diversity maintenance, ecological environment purification, regional climate regulation and other important ecological functions.
However, mangroves are always facing the survival crisis, the expansion of coastal culture ponds is considered to be the main reason of mangrove forest reduction, in the 70 s of the 20 th century, a large area of mangroves disappear in a short time due to the explosive development of the breeding industry, remote sensing monitoring shows that more than half of the worldwide area reduction of mangroves is caused by pond-surrounding culture, and besides, the pollution discharge of culture ponds is also one of the reasons of mangrove forest degradation. In recent years, in coastal areas, because the large-area outbreak of aquatic diseases causes the yield of a plurality of culture ponds to be rapidly reduced or even be dead, a plurality of farmers have to abandon or reduce the culture scale to reduce the loss, so that a plurality of abandoned culture ponds appear in the coastal areas, and the abandoned culture ponds become better choices for recovering mangroves.
CN201410294624.9 discloses a forestation technology for returning to a pond by using mangrove forest plants, which discloses a method for returning to a pond and foresting by building planting ridges and a water channel in a pond, controlling the communication of water in the water channel and external water by controlling the gate of the original sluice of the pond and arranging a plurality of planting ridges according to the size of the pond.
A method for returning forest and forest to wet by selecting a specific fishpond and selecting different tree species according to elevations is disclosed in a method for returning forest and wet by selecting a specific fishpond from a method for returning forest and wet by returning pond and forest to wet with a patent number of CN20191069306069.X, and not only can the survival rate of forestation be improved, but also the cost can be reduced.
However, mangrove plantation in culture ponds faces many problems, such as: the waste culture pond has a plurality of gravels, the air permeability of the soil at the bottom is poor, bacteria and microorganisms are bred, the pollution of aquaculture is left over, and the like. At present, most of traditional mangrove plantation directly uses large machinery to fill and level up a culture pond and then directly plant mangrove plants, the traditional method reduces the working efficiency of pond withdrawal and forest return, and the survival rate of the mangrove plants cannot be guaranteed while the input cost of mangrove plant plantation is improved.
Disclosure of Invention

Firstly, treating a culture pond: selecting a waste culture pond which is at the seaside or at the sea entrance and has broken stones and can be periodically submerged by seawater, determining the elevation suitable for the growth of the Kandelia candel through periodic detection of the seawater level in the culture pond, determining the planting area of the Kandelia candel according to the elevation, cleaning the pond, making the seawater submerge the planting area of the Kandelia candel, and adding a medicament into the culture pond, wherein the dosage of the medicament is 0.46mg/m2Soaking for 1-2 days, draining water and drying in the sun; the medicament consists of 6.5g of polyacrylamide, 3.3g of quicklime, 9g of sitosterol and 4.8g of bacterial powder;
selecting saplings: selecting a Kandelia candel seedling which is 40-70 cm high and grows for 1-2 years;
preparing before transplanting: digging out planting pits at the determined elevation of the step I, irrigating the planting pits 3-5 days before transplanting the saplings until the water content of soil in the planting pits is 70%, and then paving a soil layer containing 2g of bacterial powder per 1kg on the inner walls of the planting pits, wherein the molar mass ratio of N, P, K, Se is 4: 5: 6: 1, a fertilizer; the specification of the planting pits is 30cm multiplied by 40cm, and the distance between the planting pits is 40 cm;
fourthly, transplanting: when the seawater level of the culture pond is kept at the elevation of the planting pit, transplanting the tree seeds and the nutrition bag into the planting pit, fixing, covering soil, wherein the height of the covered soil cannot be higher than the upper surface of the soil in the nutrition bag by 6cm, and controlling the seawater level to be lower than the elevation of the planting pit;
managing after transplanting: and 6d, after transplanting, submerging the seawater normally and periodically, observing and maintaining the seedlings periodically, timely removing dead seedlings and supplementing the seedlings until the planted mangrove seedlings grow out of the support roots, and removing the fixation.
The bacterial powder is streptomyces jingyangensis, bacillus licheniformis and streptomyces heamicans according to the weight ratio of 1: 5: 4 ratio of bacteria count
Afforestation effect: after a growth period, the planted Kandelia candel seedlings die in a large area, the survival rate is low, and the survival rate of the Kandelia candel is 28% after one year.
According to the survival rate and the growth condition of each group of the Canarium stylosum after being planted for one year, the planting method can improve the success rate of planting the Canarium stylosum in the rubble area of the culture pond, and the planted Canarium stylosum can grow normally and has good growth vigor.
TABLE 1 survival Rate
Tree species Survival rate Average height/m Average ground diameter/cm
Canarium (example 1) 87％ 1.1 1.3
Tung flower tree 34％ 0.75 1
Kandelia candel 28％ 0.7 0.9
According to the survival rate and the growth condition of the tree species after one year of planting, the survival rate of the red sea olive planted in the rubble area of the culture pond by adopting the method is obviously higher than that of the Aegiceras corniculatum and the Kandelia candel, the growth condition is better than that of the Aegiceras corniculatum and the Kandelia candel, and the planting effect of the red sea olive is optimal.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
