This invention, entitled "A Physical Control Method for the Abnormal Proliferation of Cladosporium and Its Application," belongs to the field of algae control technology in water environmental protection. The technical problem to be solved is the lack of technical means, poor adaptability of existing methods, unsatisfactory and unsustainable algae control effects, and easy recurrence in the control of Cladosporium. The key points of the technical solution are a physical control method, including the following steps: Step 1: Cladosporium is mechanically destroyed to obtain pretreated Cladosporium; Step 2: Energy deprivation is applied to the pretreated Cladosporium; the mechanical destruction mentioned in Step 1 refers to a physical method that can damage the cells of Cladosporium; the energy mentioned in Step 2 includes at least one of light and nutrients.

The invention relates to the technical field of river treatment, in particular to a biological control device considering hydrodynamic conditions, which comprises a walking mechanism, a base, an identification unit and an adjusting assembly, the walking mechanism is arranged on the base, and the walking mechanism is used for driving the base to move; the identification unit is arranged on the base and is used for identifying a cladophora growth area; the adjusting assembly is arranged on the base and can spray water flow in the cladophora growth area in the water flow direction so as to increase the water flow speed of the cladophora growth area. According to the invention, the area is not suitable for the growth of cladophora by changing the water flow, so that the effect of treating cladophora is achieved.

This application discloses the application of the EDS1 protein and its encoding gene in regulating plant disease resistance, belonging to the field of genetic engineering technology. The technical problem this application aims to solve is: how to regulate clubroot resistance in plants. To this end, this application provides the application of the EDS1 protein, or substances regulating the expression of the EDS1 protein encoding gene, or substances regulating the content of the EDS1 protein, in regulating plant clubroot resistance; the EDS1 protein can be a protein with the amino acid sequence being sequence 2. This application is the first confirmation of EDS1's participation in the *Cladophora brassicae* infection cycle, and the obtained susceptible materials can be utilized as a potential breeding resource. The discovery and enrichment of breeding resources will greatly accelerate the breeding process of clubroot-resistant cruciferous plants and strengthen disease control. Furthermore, clubroot resistance can be achieved by overexpressing EDS1 in cruciferous plants through transgenic or other means.

The invention discloses a scenedesmus growth prediction method and system based on multi-source data fusion and a medium, and belongs to the field of data processing, and the method comprises the following steps: obtaining multi-source data of scenedesmus; performing quantification processing on the environmental stress data to obtain a microalgae stress inhibition coefficient, and constructing an environmental stress vector according to the microalgae stress inhibition coefficient and the environmental stress data; performing quantitative processing on the biological effect data to obtain a microalgae stress inhibition coefficient, and then determining a total effect coefficient; constructing a growth environment vector according to the growth environment data, and constructing a biological effect vector according to the biological effect data and the total effect coefficient; fusing the growth environment vector, the biological effect vector and the environmental stress vector to obtain a fusion vector; the real growth data and the real survival rate corresponding to the multi-source data of scenedesmus are obtained to construct a training set, and then a preset deep learning network model is trained to obtain a trained model. According to the invention, the prediction precision of scenedesmus growth is improved.

The invention belongs to the technical field of resource environmental protection, and discloses a water quality purification and recycling method based on macroalgae. The method comprises the following steps: constructing a macroalgae ecological bed in a water body between a reclaimed water discharge port of a sewage treatment plant and the upstream of a reclaimed water supply target river and lake; the reclaimed water discharged from the reclaimed water discharge port of the sewage treatment plant is purified by the macroalgae ecological bed and then is discharged into the reclaimed water supply target river and lake; the macroalgae are at least one of benzylothrix, hydrocystis and cladophora. The method can systematically solve the core problems of high recovery cost, harsh field planting conditions, high recycling difficulty and the like in the traditional biological treatment, and provides a new path with a wide prospect for the treatment and resource recycling of eutrophic water bodies.
