The invention relates to the technical field of moss cleaning in sewage treatment, and discloses a method for cleaning moss in a sedimentation tank, which comprises the following steps: S1, pretreating moss, and converting the moss into a state convenient to remove by physical and chemical methods; s2, spraying treatment: spraying the moss with reclaimed water containing sodium hypochloride in a temperature range of 20-30 DEG C; s3, performing ultraviolet irradiation, namely performing ultraviolet irradiation on the obtained first moss; s4, inhibiting the growth of moss, namely performing post-treatment on the second moss to inhibit the growth of the second moss; s5, waste is cleaned, moss residues, cleaning agents and other waste generated in the cleaning process are cleaned in time, influences of the residues on water quality are avoided, and moss is prevented from growing again. Through a physical and chemical combined mode, loose moss in the sedimentation tank is effectively removed firstly, then a solution containing sodium hypochloride is used for spraying the moss, it is ensured that all moss patches are in uniform contact, and the ideal chemical cleaning effect is achieved.

The invention belongs to but not limited to the technical field of plant protection, and particularly relates to application and method for improving wheat stripe rust resistance through allogenic material treatment, 250 micromoles of luteolin is used for culturing stripe rust fungus spores, germination of the stripe rust fungus spores is remarkably inhibited, 500 micromoles of luteolin is used for pretreating wheat leaves, spraying is carried out once a day, spraying is carried out three times in total, and the yield of the wheat stripe rust resistance is increased. After the leaves absorb the luteolin, the puccinia striiformis is inoculated, and the result shows that the endogenous luteolin content of the wheat plants treated by the luteolin is increased, the infection area of the puccinia striiformis is remarkably reduced, the number of puccinia striiformis spores on the leaves is remarkably reduced, and the biomass of the puccinia striiformis is remarkably reduced. The invention proves that the occurrence of wheat stripe rust can be inhibited by exogenous luteolin treatment, and a certain reference is provided for stripe rust disease-resistant mechanism research and prevention and control measures.

The invention provides a method suitable for inhibiting toxic weed ligularia virgaurea and promoting growth of forage grasses loved by cattle and sheep in alpine degraded pastures. Aiming at the defects of the existing physical and chemical weeding methods, the technical scheme of applying the ligularia virgaurea inhibitor and the nitrogen fertilizer is combined, so that the growth of the ligularia virgaurea is effectively inhibited, meanwhile, the growth of forage grass loved by cattle and sheep is promoted, and the ecological comprehensive treatment concept of treating grass with grass is realized. Experimental results show that the method can significantly reduce the biomass and coverage of ligularia virgaurea and improve the biomass and coverage of forage grasses loved by cattle and sheep, and is of great significance to treatment and improvement of toxic weeds, especially high and cold degraded pastures with dominant ligularia virgaurea. The method has the characteristics of simple operation, environmental protection and high efficiency, and is suitable for treatment and improvement of high and cold degraded pastures.

The present invention belongs to the technical field of plant genetic engineering, and relates to the technical field of crop breeding, and specifically relates to an application of a MYB transcription factor OsMYBR17 gene that simultaneously promotes tillering and panicle development in increasing rice yield, wherein the protein encoded by the OsMYBR17 gene is a protein with an amino acid sequence as shown in SEQ ID NO.1; or it is a protein with equivalent activity obtained by replacing, substituting and / or adding one or more amino acids to the amino acid sequence as shown in SEQ ID NO.1. This technical solution has discovered for the first time a gene that simultaneously positively regulates tillering and panicle development, which can promote rice tillering, increase the number of rice tillers, the panicle length of a single panicle branch, the weight of a single panicle, and the number of panicle grains per panicle, thereby increasing rice yield. The overexpression of this gene can be applied to the genetic improvement of rice plant type and yield, creating conditions for increasing rice yield and cultivating rice with a new plant type.

The invention belongs to the technical field of biochemical engineering, and particularly relates to a fermentation preparation method of a sweetening agent. The method is based on a recombinant saccharomyces cerevisiae strain, a compound carbon source is adopted, the content of residual ethanol and the range of RQ are strictly controlled to feed back, regulate and control material supplementation so as to regulate and control a cell metabolic pathway, and meanwhile, a nonionic surfactant is added to realize large-scale stable output of a target sweetening agent. The method disclosed by the invention has the beneficial effects that the utilization rate of a carbon source is increased, the accumulation of intermediate products is reduced, the dynamic stability of cell membranes and the transmembrane transport capacity of cells are enhanced, and the yield of rubusoside and rebaudioside M in the sweetening agent is greatly increased; the problems of low yield, more byproducts, high cost, difficulty in later-stage purification treatment and the like which are difficult to meet industrial production in the prior art are solved.

The present application relates to the technical field of compound planting, in particular to a kind of southern winter idle field green manure optimization configuration efficient compound planting method, including step one, astragalus sinicus seed and rape seed banding sowing;Step two, astragalus sinicus seed and rape seed sowing promote growth treatment;Step three, astragalus sinicus and rape harvesting treatment;Step four, astragalus sinicus and rape crushing and turning back to field;Step five, strengthen and promote the management.Compared with prior art, a kind of southern winter idle field green manure optimization configuration efficient compound planting method is proposed in the present application, compared with traditional simple mixed sowing, in the yield of subsequent crop rice, rape straw decomposition rate, astragalus sinicus straw decomposition rate, >2mm soil aggregate formation, soil organic matter content and so on, there is greater improvement, it can be seen that the green manure optimization configuration efficient compound planting method is more conducive to soil fertilization and improve the yield of subsequent crop rice.

The invention belongs to the field of plant genetic engineering, and provides application of alfalfa cFBP protein in regulation and control of plant types, and the nucleotide sequence of an alfalfa cFBP protein coding gene is SEQ ID NO.1 or SEQ ID NO.3. The invention further provides a preparation method of the alfalfa cFBP protein. The alfalfa cFBP protein coding gene can positively regulate and control the plant height, the branch number and the biomass of alfalfa, and the plant height, the branch number and the biomass of the plant after overexpression of the MscFBP gene are remarkably improved compared with those of a control material.
