The invention discloses a plant antifreezer and its preparation method. The plant antifreezer is preparegggggd from the following components of: by weight, 0.5-0.97% of glucose, 0.5-0.97% of cane sugar, 0.2-0.5% of potassium dihydrogen phosphate, 0.18-0.21% of novel monomolecular lipid film, 0.06-0.17% of paclobutrazol, 0.2-0.33% of amino acid, 0.02-0.05% of 6-benzylamino-purine, 0.01-0.05% of rapin, 46-48.4% of glycerin and 48.6-51% of water. The plant antifreezer provided by the invention is nontoxic and harmless, doesn't pollute the environment, and can be directly sprinkled on plant leaf surfaces, flowers and flower bus. The preparation method is simple and requires low cost. Effective antifreezing period can reach 15-20 days. By the adoption of the plant antifreezer, lower temperature freeze injury resistance of plants can be enhanced and the freeze injury can be rapidly mitigated after freeze injury. The plant antifreezer provided by the invention can be used to form a protection film on the surface of a plant and protect the plant from cold, and has an effect of preventing diseases.

The invention belongs to the technical field of marine organisms, and concretely relates to a method for the efficient ultralow temperature cryopreservation of turbot sperms. The method comprises the following steps: mixing the seminal fluid of turbots with an antifreeze liquid according to a volume ratio of 3:1-4:1, carrying out two-step cooling treatment, carrying out one-step balancing, adding to liquid nitrogen (having a temperature of -196DEG C), and preserving; and the antifreeze liquid is composed of a diluent, an antifreeze agent and an additive. High-quality frozen sperms obtained through the method for the efficient ultralow temperature cryopreservation of turbot sperms are of great significance of the artificial breeding, germplasm preservation, heredity diversity and sustainable culturing of the turbots.

The invention provides an environment-friendly water-based paint, the formula of which includes a composite color block and component A, and the component A includes the following components in mass percentage: 85.0%-95.0% of water-based elastic acrylic emulsion; 0.1% of defoamer ~0.5%; preservative 0~3.0%; thickener 0.1%~5.0%; film-forming aid 1.2%~8.0%; antifreeze 1.0%~3.0%; softener 1.0~21.0% and water 0~20.0% ; The mass ratio of component A to the composite color block is 5:100 to 65:100. The invention also provides monochrome semi-finished products and color block semi-finished products for preparing composite color blocks, and their preparation methods. The present invention can prepare environment-friendly water-based paint with imitation stone effect through the combination of these raw materials and A component. This kind of coating not only has excellent environmental protection, but also has the effect of imitating stone, which can meet the needs of market diversification, human culture, creativity and individualization, and solve the problem of single color of the coating without increasing the load-bearing load of the building.

The invention discloses a low-temperature peracetic acid disinfectant and a preparation method thereof. The low-temperature peracetic acid disinfectant is prepared by mixing a composite low-temperature solvent and peracetic acid in any proportion, and the composite low-temperature solvent comprises the following components in percentage by mass: 60-99% of water, 1-40% of an antifreezing agent, 0-5% of a thickening agent and 0-5% of a corrosion inhibitor. The low-temperature freezing liquid can be used at different low temperatures, the lowest freezing point can reach -25 DEG C, and the low-temperature freezing liquid also has the characteristics of small metal corrosion, low volatilization and low irritation. The invention solves the dilemma of lack of efficient, stable and environment-friendly products in current low-temperature disinfection, solves the problems of poor stability, high irritation, low activity at low temperature, poor effect and the like of conventional products, and can be used for disinfection in various links of a cold chain and various low-temperature environments.

The invention discloses an artificial cultivation method for increasing melastoma dodecandrum fruit yield. The method includes steps: (1) land selection and preparation; (2) seedling cultivation; (3)transplanting; (4) field management including management in fertilization, watering and freeze and cold protection; (5) fruit harvesting. The artificial cultivation method for increasing melastoma dodecandrum fruit yield has advantages that by means of cutting seedling cultivation, the survival rate of cultivated melastoma dodecandrum is high, melastoma dodecandrum fruit yield can be increased while quality is improved, and sufficient raw material sources can be provided for further comprehensive utilization of melastoma dodecandrum fruits. By adding of cold-proof antifreeze agents, quality ofagricultural products is improved, resistance to drought, cold and diseases of crops can be improved, and accumulation and residues of farm chemicals and chemical fertilizers are evidently reduced.
