The invention belongs to the technical field of biological energy and environmental engineering, and particularly discloses a method for treating a chlorella circulating culture solution through Fenton oxidative coupling activated carbon adsorption to solve the growth inhibition phenomenon caused by extracellular polymeric substance accumulation in the microalgae circulating culture process so as to achieve cyclic utilization of the chlorella culture solution and application of the chlorella culture solution. By means of Fenton oxidative coupling activated carbon adsorption, chlorella extracellular polymeric substances (EPS) can be effectively degraded and oxidized and decomposed into small-molecule organic substances, the growth inhibition effect of the small-molecule organic substances on chlorella is relieved, an organic carbon source can be provided for growth and metabolism of chlorella, and growth of chlorella is remarkably promoted. According to the method, the chlorella circulating wastewater is treated and recycled through Fenton oxidative coupling activated carbon adsorption, so that the yield of chlorella biomass can be effectively increased, and the production and culture cost is reduced.

The invention discloses an application of a PtoELF3.1 gene in creation of non-dormancy evergreen poplar, and belongs to the fields of biotechnology and molecular biology, and the poplar ELF3.1 gene is a protein encoding an amino acid sequence as shown in SEQ ID No.1. A PtoELF3.1 gene is targeted through a CRISPR / Cas9 gene editing system, and a populus tomentosa Ptoelf3.1 mutant strain is obtained. Compared with a populus tomentosa wild type (WT) plant, the Ptoelf3.1 mutant plant still keeps the phenotype of evergreen and non-dormancy of terminal buds and lateral buds under the short-day condition in autumn and winter. The invention shows that the poplar is insensitive to a short-day condition due to knockout of the PtoELF3.1 gene, and the response to seasonal change is lost, so that the growth state of evergreen and non-dormancy is maintained. The method has great application prospects in the aspects of improving photosynthetic carbon sequestration of forest trees, increasing the wood yield and creating ornamental tree germplasm.

The invention provides a breeding application of a cotton GhD05G2577 gene in increasing the plant germination rate, the biomass, the seed size and the thousand seed weight. Through a transgenic technology, an arabidopsis thaliana homozygous line plant over-expressing the GhD05G2577 gene is obtained. Compared with a wild strain, the early germination rate of a transgenic plant in a 1 / 2 MS plate is obviously increased; in the seedling stage, the leaf number is increased, the leaf length and the leaf width are increased, the plant height is increased, the chlorophyll content SPAD is increased, and the fresh weight, the dry matter content and the biomass accumulation are remarkably increased; the fruit shows that the legume length and width are increased, the seed length and width are increased, and the thousand seed weight is increased, and all reach a significant level. When the gene is applied to high-yield and income-increasing breeding of plants, the germination rate of the plants can be increased, biomass accumulation of the plants can be increased, the seed size and thousand seed weight can be increased, and an alternative scheme is effectively provided for high-yield molecular breeding of the plants.

This invention provides the application and method of Streptomyces S16-1 in promoting the growth and salt stress tolerance of Leymus chinensis, belonging to the field of microbial technology. Streptomyces S16-1 was isolated from saline soil, with the preservation number CCTCC M 20251940, and its 16S rDNA sequence is shown in SEQ ID NO:1. The Streptomyces S16-1 has functional activities such as salt and alkali tolerance, phosphorus solubilization, nitrogen fixation, and production of 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase. The microbial fertilizer is obtained by expanding the culture of Streptomyces S16-1. Compared with chemical fertilizers, the microbial fertilizer used in this invention is more environmentally friendly. It can not only improve soil fertility and help plants improve their salt and alkali resistance, but also promote the balance and diversity of soil microbial communities, which helps maintain the health and stability of the soil ecosystem.

The invention belongs to the technical field of seed treatment, and relates to a growth-promoting microbial active seed for repairing degenerated typical grassland and a preparation method thereof, and the preparation method comprises the following steps: preparing a carrier growth-promoting microbial agent from a specific strain; after grass seeds are disinfected and soaked, a carrier growth-promoting microbial agent is firmly loaded on the surfaces of the seeds by adopting a process of coating the seeds with a functional material layer by layer, and the growth-promoting microbial active seeds are prepared.
