The invention belongs to the technical field of plant growth regulators, and particularly relates to an application of a plant growth regulator containing compound sodium nitrophenolate and DCPTA in increasing the tomato yield and improving the tomato quality. Comprising the following components in parts by weight: 5-90 parts of compound sodium nitrophenolate, 15-270 parts of DCPTA, 50-400 parts of a solvent, 10-200 parts of an emulsifier, 0-60 parts of an anti-freezing agent, 0-10 parts of a preservative, 1-10 parts of a defoaming agent and the balance of water, wherein the weight ratio of the compound sodium nitrophenolate to the DCPTA is 1: 3. The plant growth regulator disclosed by the invention can effectively promote the expansion of tomato fruits, increase the flowering number, the young fruit number, the plant height, the single fruit weight, the maximum transverse diameter and the yield, achieve the purpose of increasing the yield, and also can improve partial nutritional quality (vitamin C content, soluble sugar and soluble solids) of the tomatoes to a certain extent, so that the yield of the tomatoes is increased. The content of titratable acid can be reduced to a certain extent, and the compound is safe to tomatoes, safe to the environment and small in residue.

The application discloses application of HD-ZIP transcription factors in quality regulation of tomatoes, and the protein has functional redundancy, and the functions of the protein are jointly regulated by two genes, wherein a CDS sequence of the gene Solyc03g034130.2 is shown as SEQ ID NO. 1, and a CDS sequence of the gene Solyc03g034110.2 is shown as SEQ ID NO. 2. A tomato transcription factor mutant library is constructed through CRISPR technology, and a mutant Tom6-155 which simultaneously inhibits expression of two homologous genes of the HD-ZIP transcription factor is screened. Based on observation of a phenotype of the mutant, the inventors determine that the HD-ZIP transcription factor is related to tomato fruit quality. Compared with a wild type, the brix content of the tomato fruit of the mutant is increased. It is indicated that Solyc03g034130.2 and Solyc03g034110.2 play important negative regulation roles in a tomato fruit quality formation process. The application lays a good genetic resource foundation for cultivation of a new tomato variety with high quality.

The invention discloses a pollen suspension for improving the fruit shape and quality of a perfume pomelo as well as a preparation method and application of the pollen suspension. The pollen suspension is obtained by mixing a nutrient solution and Majia pomelo pollen; the nutrient solution is prepared from the following raw materials in parts by weight: 8 to 12 parts of xanthan gum, 5200 to 7800 parts of cane sugar, 36 to 54 parts of calcium gluconate, 4 to 6 parts of boric acid and 40000 to 60000 parts of water; the activity of the Majia pomelo pollen is not lower than 70%; the solid-to-liquid ratio of the Majia pomelo pollen to the nutrient solution is (0.2-0.6) g: 1L; the method can be used for improving the fruit shape and quality of the perfume pomelo, and compared with single-sexual fruiting in a natural state, the method can improve the fruit quality; the malformed fruit rate and the peel thickness of the perfume pomelo are reduced, the edible rate of fruits is improved, and the content of soluble solids in pulp is increased; compared with a traditional cross pollination mode, the method has the advantages that the seed characteristics can be optimized, the seed state of fruits can be obviously changed, and the industrial problem that quality improvement is accompanied by grain increase is solved; the pollination operation efficiency can be improved, and manual labor investment is saved.

This invention discloses a closed-loop soil improvement method for vineyards using organic fertilizer synergy, comprising the following steps: seasonal directional grass cultivation, preparation of Bacillus subtilis agent, preparation and application of self-made organic fertilizer in the early stage of vineyard establishment, and closed-loop synergistic improvement method; the closed-loop synergistic improvement method is divided into early stage improvement and late stage improvement, relying on grass return to the field and Bacillus subtilis to maintain soil fertility and nutrient cycle.
