Description

Large-scale suaeda salsa coastal mudflat repairing method and device using underground cultivation land

Technical Field

The invention relates to the technical field of ecological restoration, in particular to a method and equipment for restoring large-scale suaeda glauca coastal mudflats by using underground cultivation land.

Background

Suaeda glauca (Bunge) Bunge is an annual herb with a height of up to 1 meter. The stem is upright, thick, cylindrical, light green, and has a strip edge, and the upper part is multi-branched; the branches are slender, ascending or inclined. Leaf-shaped strip-shaped and semi-cylindrical. The flower is also female in both sexes, either solitary or a collection of 2-5 blooms, mostly living near the base of the leaf. The cygon is covered in the flower quilt and the pericarp is membranous. The seeds are transverse or oblique. The flower and fruit period is 7-9 months. Distributed in Mongolia, Russia (Siberia and far east), Korea, Japan, and China; in China, it is distributed in Heilongjiang, inner Mongolia, Hebei, Shandong, Jiangsu, Zhejiang, Henan, Shanxi, Shaanxi, Ningxia, Gansu, Qinghai and Xinjiang south. Growing on saline-alkali soil such as seashore, wasteland, canal and shore, field, etc. More than 20 varieties of suaeda glauca are sold in the red beach of Liaoning's Panjin in China. Therefore, the suaeda glauca also has great travel ornamental value. The method for repairing the coastal mudflat not only has great significance for ecological repair, but also can drive related tourism industries and promote economic development. The so-called red beach is mainly used for tourism appreciation, the plant color of the suaeda heteroptera in the whole life cycle is red, and the shape of the plant which just germinates is like a wing, so the plant is called suaeda heteroptera. The coastal beach degree is mainly a common seepweed species at present.

Suaeda salsa (L.) Pall.) is a plant of the genus Suaeda of the family Chenopodiaceae. Annual herbaceous plants, 20-80 cm high, green or purplish red. Upright stem, cylinder, yellow brown, with micro-strip edge and without hair; branches mostly concentrate in the upper part of the stem, thin, scattered or ascending. Leaf bar shape, semi-cylinder shape. The clitocybe inflorescence usually contains 3-5 flowers, is axillary and is arranged into a discontinuous spike-shaped inflorescence on a branch. The cygon is wrapped in the flower quilt. Transverse, biconvex or skewed oval seeds. The flower and fruit period is 7-10 months. Distribution in europe and asia; in coastal areas of China, such as northeast, inner Mongolia, Hebei, Shanxi, northern Shaanxi, Ningxia, Gansu (northern and Western), Qinghai, Xinjiang, Shandong, Jiangsu and Zhejiang. Grow in saline-alkali soil and form a single community at beaches and lakes. The suaeda salsa contains protein, dietary fiber, polysaccharide, pigment, flavonoid compounds and the like, and grains contain rich conjugated linoleic acid, so that the suaeda salsa has higher edible value and medicinal value.

The common seepweed herb and common seepweed herb are different mainly in that the common seepweed herb germinates green and gradually turns red after autumn. Is mainly eaten or used and can be viewed. Suaeda heteroptera is mainly an ornamental variety, has extremely poor taste and is not generally eaten.

Suaeda glauca is an annual herb. The stem is upright, the height is 30-100 cm, and the stem has single or branch, fine longitudinal stripe or hair. The leaf shape is 1.5-3 cm long and 1-3 mm wide, and has long fine hair or quilt powder particles which are usually bent and extended upwards. The flower is amphoteric, one or more flowers cluster in the axilla of the leaf, and have short peduncles; small bract 2, wide oval, white; the sepals 5 are long round, the tips of the sepals are blunt and round, the fruit period is increased, the sepals are thick, the back of the sepals is provided with ridges, the inner surface of the sepals is concave, and the sepals are shaped like a pentagram; a stamen 5; and a column head 2. Flat fruits and covered in the calyx; the seeds are nearly circular, have granular point lines, have the diameter of about 2mm and are black. The flowering period is 7-8 months, and the fruit period is 9-10 months. Shi xing shan, Ezhou, etc. Cultivated in mountain vegetable garden with elevation below 1200m and sand soil beside the wild river. The seed is originally a wild plant growing on alkaline soil. Distributed in provinces (districts) such as Shaanxi, Gansu, Jiangsu, Shanxi, Shandong, Hebei, Liaoning, inner Mongolia, etc. Also in Mongolia and Sulian Siberian regions.

Suaeda glauca is generally relatively tall, big and strong, and the green color does not turn red for a long time and is green.

Suaeda heteroptera has great ecological function, has irreplaceable effect in the aspects of purifying environment, regulating climate and the like, and is an important wetland tourism source. In recent years, landscape ecology is damaged due to artificial interference such as artificial sea blocking, field building, mudflat culture and the like. In 1997, the red beach in delta Liaoning began to have partial degeneration and death. Almost endangered until 2019. In 2002, the natural suaeda heteroptera community area in the national natural protection area of the double Taiwan estuary continuously shrinks and begins to disappear in a large area. In order to realize ecological resources of the intertidal wetland, people adopt a plurality of methods, including the artificial cultivation of suaeda heteroptera. The traditional method for artificially cultivating the suaeda heteroptera has huge cost and no effect on reducing the tidal flat. The traditional suaeda salsa seeding rate is low, and in order to achieve a certain scale density, frequent reseeding is needed, so that the efficiency is low, and the cost is high. Therefore, a new suaeda heteroptera planting method capable of solving the problems is needed.

In particular, a plurality of tourist attractions are constructed with huge investment, but after the scenic spots are constructed, the suaeda salsa is endangered to be extinct, so that great economic loss is brought.

Five hypotheses are proposed at present for the degradation and even disappearance of Suaeda salsa on coastal beach

Sea pollution, as it is, results from the detection of pollutants or herbicides in the sea. The tide crab phagocytosis states that the environmental changes are thought to make the tide crab without food. The large amount of tidal crabs phagocytose the tender buds of the suaeda salsa, so that the suaeda salsa cannot grow or even disappear. And thirdly, the salinity of the seawater is too high, namely the salinity of the suaeda salsa growing condition is about 13 thousandth, and the salinity of the seawater exceeds 30 thousandth at present, so that the suaeda salsa seeds cannot germinate. And fourthly, when heavy metals exceed standards, the beach pollution is considered to contain a large amount of cadmium elements, and the cadmium elements can prevent the suaeda salsa from poisoning and growing. Fifthly, the rise of the tidal flat is considered to be the cause of the death of the suaeda salsa.

The inventors have long studied and investigated natural phenomena to find that none of the five hypotheses can be established. Assuming that the suaeda degradation is due to pollution, the beach phenomenon is: suaeda salsa is extinct because the pollution is a extinct attack to the Suaeda salsa, and the actual situation is that the Suaeda salsa has a considerable area. And researches find that the content of the pollution in the sea is very little under the self regulation of the sea water, and the pollution can not be established because the content of the pollution in the sea is not very little and can not threaten the suaeda salsa. The tidal calling crabs can not stand because most of suaeda glauca dies when the relevant management departments put down the net to capture 30 kilograms of tidal calling crabs and capture the tidal flat of the tidal calling crabs overnight. The over-high salinity of seawater actually means that the laboratory belongs to the environment with great difference with the natural environment data. Practice shows that the highest salinity tolerance of the suaeda glauca can reach 60 thousandth of the salinity tolerance in the natural environment, the suaeda glauca can still normally germinate, and the condition that the salinity is too high cannot be met. When the metal content exceeds the standard, the soil suaeda salsa with high heavy metal content can sprout, and the soil suaeda salsa with relatively low heavy metal content cannot sprout, so that the heavy metal content exceeding cannot be met.

The coastal mudflat is increased, and practice shows that the suaeda glauca all dies in one night after the mudflat is reduced, so that the mudflat reduction cannot solve the problem of the death of the suaeda glauca and cannot be realized.

According to actual investigation, the last death of suaeda salsa is immediately large-area death after the tide in the middle 9 th month, and when the suaeda salsa is dead, the leaves fall off completely, and the root system is rotten completely. Through a large number of research and practice inventor teams, the conclusion is that the death of the suaeda salsa is caused by the change of the surrounding environment, the living environment of the suaeda salsa is changed when the field is built around the sea, the flood and flood tide time is prolonged, and the sea surface is raised, so that the suaeda salsa is soaked in water for a long time, and the death of the suaeda salsa is caused by suffocation.

Through retrieval, a Chinese patent with the application number of 201810034286.3 discloses a method for quickly constructing an ecological landscape type shelter belt on a newly reclaimed beach, which belongs to the technical field of agricultural cultivation and comprises the following steps: step A: mechanically digging soil, turning over soil and breaking the mud flat salt barrier, and B: excavating a main river channel, and constructing an ecological river bank, wherein the step C is as follows: combining various soils to improve the soil property, and step D: and (5) planting landscape tree species. The method for directly planting the tree species of the single variety is easy to cause the problem that the tree species of the single variety is not suitable for the living environment of local soil, so that the survival rate of the tree species is low, the expected effect cannot be achieved, and economic loss is caused.
