Porous bacterial cellulose skin repair material with density structure and preparation method thereof

The invention relates to a porous bacterial cellulose skin repair material with a density structure and a preparation method thereof. The porous bacterial cellulose skin repair material with the 'upper dense and lower loose' structure similar to human skin is prepared by controlling the culture condition of bacterial cellulose and adding sustained-release microspheres in the culture process. A loose layer is tightly combined with a dense layer, so that obvious physical layering is avoided, and the structural continuity is good; and gradient changes of the structures are produced in the loose layer and the dense layer, and multiple pores distributed uniformly are formed in the loose layer, so that the upper dense and lower loose gradient structure of the human skin is simulated to the utmost degree. Cells easily enter the material, the healing period of a wound is obviously shortened, and proliferation of healed scars is effectively reduced; and good air permeability and water holding property of the bacterial cellulose are kept, the wound surface can be kept in a wet environment, and healing of the wound surface is facilitated. The forming process is simple, the culture period is short, the preparation process is environment-friendly, simple, convenient and quick, and the preparation cost is low.

The invention discloses a nutritional buckwheat sprout cultivation method. The nutritional buckwheat sprout cultivation method includes the following steps of 1 germination accelerating, 2 sowing, 3 management and 4 harvesting. The nutritional buckwheat sprout cultivation method is simple in process, a cultivation cycle is shortened to be 8-9 days, the germination rate is 94-96%, the resistance is strong, and buckwheat sprouts vigorously grow, and are rich in nutrition, diversified in health care function and capable of promoting metabolism, enhancing immunity, protecting cardiac-cerebral blood vessels, maintaining beauty, keeping young, protecting the mouth, relieving internal heat or fever and resisting cancers. Buckwheat seeds are subjected to microwaves, ultrasound and soaking in sprouting liquid, the sprouting liquid rapidly penetrates into the seeds, the time is saved, nutrition of the seeds and cell activity are strengthened, the germination rate of the seeds is improved, resistance is enhanced, and the germination time is shortened. After germination accelerating, non-germinated seeds are directly added to a cultivation matrix of a seedling tray, antimicrobial and insecticidal effects are achieved, and the survival rate of the seeds is improved, so that buckwheat sprouts grow upright, are rich in nutrition, have a health-care function, adsorb harmful substances and are nutritional, safe, green and healthy.

Ecological functional compound fertilizer and preparation method thereof

The invention belongs to the field of fertilizers for crops and particularly relates to an ecological functional compound fertilizer and a preparation method thereof. The ecological functional compound fertilizer is prepared from the following main components: sludge, a compound fertilizer, a microbial agent, an organic waste, a soil heating agent and an oxygen supplier. The sludge obtained from the treatment of municipal domestic wastewater and the organic waste serve as organic matters, contain multiple nutrients and can be combined with the compound fertilizer to increase the utilization rate of the compound fertilizer and increase the content of organic matters in soil; the added soil heating agent can preserve the temperature around the roots of crops in deep soil and prevent crops from being frostbitten and frozen to death; the added oxygen supplier can supply oxygen to microorganisms in soil and cells in crop roots to increase the activity of the microorganisms in soil and the crop roots, accelerate the absorption of the ecological compound fertilizer, enhance the adversity, disease and cold resistance of crops, improve the structure and fertility of soil and promote the growth of crops; the pollution of sludge to environment can be reduced, and the sludge can be reutilized; and the ecological compound fertilizer is safe to people, animals and environment and is natural, innoxious and environmentally friendly.

Method for preparing DEHP degrading bacterial agent and method for effectively reducing DEHP pollution in vegetable production

The invention discloses a method for preparing DEHP degrading bacterial agent and a method for effectively reducing DEHP pollution in vegetable production. The bacterial agent is prepared by the steps: activating rhodococcus sp. 2G and then carrying out fermented culture, centrifuging the fermentation liquid, collecting bacteria, adding a protective agent to the bacteria, pre-freezing, and carrying out vacuum freeze-drying of the pre-frozen bacteria to obtain the DEHP degrading bacteria freeze-dried bacterial agent. A certain proportion of the bacterial agent is added in a farmland having soilpolluted by the DEHP, so the accumulation amount of the DEHP in planted vegetables is reduced while the DEHP in the soil is removed; by addition of the DEHP degrading bacterial agent and colonizationof the degrading bacteria at vegetable rhizospheres, the residual amount of the DEHP in the polluted soil and the planted vegetables can be effectively reduced. The method not only remediates the DEHP polluted soil in farmland, but also produces agricultural products safely, namely a concept of remediating while producing, has the advantages of high treatment efficiency, low cost and no secondarypollution, and has important application prospects in prevention and control of organic pollution in the soil of the farmland.
