The invention provides a sugarcane anthocyanin adjustment gene ScRS and application thereof, belonging to the field of biotechnology. The adjustment gene ScRS has a sequence as shown in SEQ ID NO.1, a primer is designed according to a gene sequence of a corn anthocyanin transcription factor RS, and a full-length sequence of an anthocyanin transcription factor ScRS is obtained from sugarcane by adopting a homological cloning technology; the length of an opening reading frame of the sugarcane gene ScRS is 1722bp, and 573 amino acids are coded; the E value is equal to zero in BLAST homological search of a gene related with numerous corn anthocyanins, and the situation shows that a cloned gene is really the gene related with anthocyanins; enzyme cutting sites Kpn I and Sal I are added to two ends of the ScRS sequence respectively to construct a plant expression vector pCAMBIA1301-35SN-ScRS, sugarcane callus tissues are bombarded and transformed through a gene gun, the transformed callus tissues become bright purple red, and the situation further proves that the cloned gene has a function of developing the color of the sugarcane callus tissues.

The invention provides a coupled floating body device for preventing and controlling water bloom by utilizing a slow-release algal inhibition agent. The coupled floating body device structurally comprises a single floating body. The single floating body comprises gauze elements, a plurality of hemispherical purifying balls, a fixing rod and a floating body main frame. A hanging ring A is installedon two sides of each hemispherical purifying ball respectively, hanging rings B and hooks are arranged on the floating body main frame, the hemispherical purifying balls are fixed to the fixing rod through the hanging rings A, two ends of the fixing rod penetrate through the hanging rings B to be hung on the floating body main frame, and the gauze elements are located in the hemispherical purifying balls. The coupled floating body device has the advantages that dismounting is simple, flexible and quick, and the device can be dragged to any area of a water body as required and has good maneuverability; the algal inhibition efficiency is high, the duration time is long, and the ecological safety is high; full contact between the algal inhibition agent and algae on the surface layer of the water body is ensured, diffusion of the algal inhibition agent is facilitated, and the influence of bottom mud attachment on the algal inhibition effect is avoided; the algal inhibition agent is convenient to supplement and update and meets the long-term water bloom prevention and controlling demand.

The invention provides a compound treatment agent for a landscape water body. The compound treatment agent comprises polyferric sulfate and purple parent rock. The compound treatment agent provided by the invention has the advantages of low cost, wide source and environmental friendliness, can be used for treating landscape water bodies different in pollution degree and realizes high purifying efficiency and good treatment effect, wherein the removal efficiency of nitrogen and phosphorus is high, and the removal rate of total nitrogen in the seriously-polluted landscape water body can reach 57.94% while the removal rate of total phosphorus can reach 83.63%; and the damaged ecological balance can be effectively restored so that the ecological system resumes virtuous cycle.

The invention relates to a novel adsorption material for efficiently removing phosphorus in water bodies, and belongs to the technical field of environmental protection. In the present invention, lanthanum compounds and aluminum compounds are selected as raw materials, and a highly efficient phosphorus removal adsorbent is prepared by co-precipitation, which can effectively remove different types of phosphorus in water through electrostatic attraction, ligand exchange and oxygen vacancy on the surface of the adsorbent. phosphorus. Compared with the existing adsorbent for phosphorus removal, the invention has simple preparation process, low production cost, high phosphorus removal efficiency, long-lasting phosphorus fixation effect, low ecological safety risk, wide application range of pH, and convenient storage, transportation and use.

The invention belongs to the technical field of ecological restoration and particularly relates to a water body ecological restoration method. The water body ecological restoration method comprises the steps that the water surface is cleaned, then submerged plants, emergent aquatic plants and floating-leaved plants are planted, and aquatic animals are put in. According to the water body ecological restoration method, sludge at the water bottom is treated with a plant blanket in-situ coverage method, root systems of the emergent aquatic plants are fixed with pollution-free clay, and a putting-in type planting method is adopted for the floating-leaved plants and the emergent aquatic plants. The aqueous plants can provide an adhesion symbiotic space for microorganisms, and provide a food source for aqueous animals, fish and shellfish are put in when the aquatic plants grow stably, and a rapid and simple water body forest system is formed. By means of the water body ecological restoration method, the effects of fixing sludge at the water bottom, restoring the natural ecological environment and maintaining the water to be clear permanently can be achieved; meanwhile, a dwelling site can be provided for fish and birds, and certain river landscape can be formed.

The invention discloses a bimetal wind wave resistance phosphorus locking material which is prepared by the method including the steps: granulating powdery dolomite attapulgite clay and then performing high-temperature heat treatment to obtain a semi-finished product; soaking the semi-finished product into lanthanum chloride and aluminum chloride mixed solution for loading; performing low-temperature stabilizing treatment, cleaning and drying to obtain the bimetal wind wave resistance phosphorus locking material. The material is high in phosphorus fixation capacity and has remarkable wind waveresistance, and lanthanum and aluminum phosphorus fixation functions in pH (potential of hydrogen) value change of different water environments can be transformed, so that complete phosphorus fixation capacity is realized. The material is wide in material drawing, low in price, natural, non-toxic and high in ecological safety and has a wide application prospect.

The invention provides a seed coating agent for ecological restoration of desertified land. The raw materials of the seed coating agent include: filler 80-110, superabsorbent resin 1-4, plant growth regulator 0.03-0.11, humic Acid 10-15, rhizosphere microbial strains 0.5-1; also include: adhesive, the total mass of the filler, superabsorbent resin, plant growth regulator, humic acid, rhizosphere microbial strains and the adhesion The mass volume ratio of the agent is (3-8):1, preferably 6.25:1 or 5:1. The germination rate of seeds coated with the seed coating agent is obviously improved, and the root-to-shoot ratio of seedlings is obviously increased, and can be applied in agricultural production.

The invention relates to sewage treatment and urban water supply treatment, in particular to a preparation method of a series of ecologically safe composite high-efficiency flocculants used for water supply pretreatment, industrial waste water or domestic sewage treatment. It uses iron salt, starch, absolute ethanol, and sodium hydroxide as raw materials, of which: iron salt and corn starch are the main components, absolute ethanol or water is used as the reaction solvent, and sodium hydroxide is used for the modification of corn starch; iron salt The mass ratio of medium iron to starch is 1:1-1:100; specific preparation: 1) modification of starch; 2) composite reaction to obtain white-yellow or reddish-brown emulsion flocculant. The invention is economical, efficient, high in ecological safety, wide in applicability, free of secondary pollution, friendly to the environment and non-corrosive to equipment.
