The invention provides a bacillus velezensis QT1 and an application of the bacillus velezensis QT1. The classification name of the bacillus velezensis is bacillus velezensis QT1, and the bacillus velezensis is preserved in the China Center for Type Culture Collection on November 12, 2025, the preservation address is Wuhan University, Wuhan, China, and the preservation number is CCTCC NO: M 20252531. The strain shows remarkable biological control efficiency, realizes effective control on various plant pathogens, and can prevent and treat tomato bacterial wilt and tea tree anthracnose. In addition, the bacillus velezensis QT1 can also effectively kill root-knot nematodes (especially meloidogyne incognita). When the strain is applied to plant cultivation, the growth of various pathogens can be remarkably inhibited, the health and yield of crops are improved, the strain is environment-friendly, the use of chemical pesticides is reduced, soil pollution is avoided, and the development requirement of sustainable agriculture is met.

This invention belongs to the field of industrial solid waste resource utilization and inorganic material preparation technology, specifically relating to a coupled method and system for preparing jade core stone from gypsum waste residue and producing sulfuric acid as a byproduct. The coupled method includes: drying the gypsum waste residue in a first drying device to obtain semi-dry gypsum waste residue, then drying the semi-dry gypsum waste residue in a second drying device to obtain anhydrous gypsum raw material; mixing and grinding the anhydrous gypsum with pre-set auxiliary materials, and then processing it through a melting furnace roasting device, a calendering device, and a segmented crystallization annealing device to prepare jade core stone products, wherein the waste heat from the melting furnace roasting device, the calendering device, and the segmented crystallization annealing device is all returned to the second drying device; during the calcination of the anhydrous gypsum mixed and ground with pre-set auxiliary materials in the melting furnace roasting device, the sulfur-containing flue gas generated during the calcination process is collected and sequentially treated through a waste heat recovery device, a purification drying device, and a two-transfer two-absorption device to obtain industrial-grade sulfuric acid.

The invention discloses a method for quickly transforming spring low-yield tung tree forests, and belongs to the technical field of tung tree grafting. The problems that in aleurites fordii low-yield forest transformation, seedling sowing offspring hereditary characters are unstable, fruiting is late, the economic return period is long, traditional grafted seedling transplanting nursery stock cultivation time is long, improved variety asexual breeding popularization is slow, and production management and protection cost is high are mainly solved. The innovation of the method comprises the overall cooperation of the technical means of treating a seed tree to cultivate robust scions, determining the optimal grafting time, adopting the optimal grafting method, optimizing management after grafting and the like. According to the method, tree vigor recovery, fast stock-scion wound healing and fast growth after low-yield tung tree grafting are achieved for the first time, flowering and fruiting in the current year after grafting can be achieved, the fruiting amount in the next year is remarkably increased, the high-yield period is entered in the third year, the method is particularly suitable for rapid improved variety transformation of tung tree low-yield forest stand, and economic benefits are quite remarkable.

The invention relates to the technical field of river regulation, discloses an ecological reinforcing composition for river levees and lake levees and a construction method of the ecological reinforcing composition, and aims to solve the problems that traditional river levees and lake levees depend on riprap / piling, the anti-impact stability is weak, the consumption amount of industrial and mining solid waste is low, and ecological damage is caused. According to the invention, a cement-free flow state system is formed by taking multiple industrial and mining solid wastes as a core functional component, matching with an in-situ embankment soil material as an aggregate and combining with a geopolymer activator and an ecological regulator; during construction, double-row drilling-layered pouring is performed along a river embankment / lake embankment base, and an integrated structure of a deep embedded embankment foundation stable layer and a surface layer anti-impact ecological barrier is formed after solidification. The method is high in anti-impact capacity and good in ecological compatibility, industrial and mining solid waste is consumed in a high proportion, solid waste stockpiling pollution is greatly reduced, the flood and washing resisting capacity of an embankment foundation is enhanced, and the problems of ecological damage and high cost of a traditional technology are solved.

The invention belongs to the field of fertilizers, and particularly relates to a special compound fertilizer for golden camellia cultivation. The compound fertilizer comprises the following raw materials in parts by weight: 10-15 parts of ammonium chloride, 6-10 parts of potassium sulfate, 2-4 parts of fulvic acid salt, 3-6 parts of shell powder, 2-5 parts of polyglutamic acid, 2-5 parts of chitosan and 2-3 parts of a diethyl aminoethyl hexanoate solution. The fertilizer suitable for growth of camellia nitidissima is prepared according to the proportion of the effective substances. The fertilizer is rich in nutrition and simple in preparation process and has a good economic prospect.

The invention discloses serine type carboxypeptidase for inhibiting growth of blue-green algae and belongs to the technical field of biology and environmental protection, bacillus altitudinis FY1 is screened and separated from a rice field water sample, it is found that protein serine type carboxypeptidase exists in the FY1 in the peptidoglycan biosynthesis process, the nucleotide sequence of the protein serine type carboxypeptidase is shown as SEQ ID 0.1 in a sequence table, and the nucleotide sequence of the protein serine type carboxypeptidase is shown as SEQ ID NO. The serine type carboxypeptidase is targeted to cell walls of cyanobacteria, has an efficient splitting effect on the cyanobacteria, can kill harmful cyanobacteria and is used for treating cyanobacteria bloom.
