The invention discloses special EM (Effective Microorganisms) bacteria powder for aquaculture, as well as a preparation method and application of the special EM (Effective Microorganisms) bacteria powder. Bran, corn flour, amino acid powder and the like, which are used as dry matter fillers, are mixed with brown sugar, glucose and the like to obtain a mixture; the mixture is subjected to sealing fermentation at 25-37 DEG C for about 10 days by lactic acid bacteria, bacillus licheniformis and bacillus coagulans, so that fermented materials are prepared; then the prepared fermented materials are dried and crushed and are mixed with bacillus subtilis to obtain a final product. The EM bacteria powder can be directly scattered in a water body to inhibit pathogenic microorganisms through mass propagation of probiotics, decompose harmful substances in the water body, promote the growth of normal floras and beneficial algae in a cultivation ecosystem and keep the ecological balance of the aquaculture water body. The method is adopted to prepare the EM bacteria powder, the fermentation period is short, the process is simple, the equipment investment is low, the materials are convenient to obtain, and the method is easy to implement and is suitable for industrial production and self-production of households.

The present invention discloses an internal fixed grafting seedling-cultivating method for melons, fruit tree and vegetables. Said method is characterized by that it adopts the following steps: using stock and grafting seedling which are synchronously sowed and grown until 0.5-3 main leaves are grown; for solanum fruits, using knife to horizontally cut between their seed leaf and first main leaf or first main leaf and second main leaf; for melons, remaining one seed leaf and horizontally cutting; using steel needle, bamboo needle or plastic wire whose diameter is 0.4-0.6 mm and length is 8-12 mm as grafting needle, its two ends are respectively inserted into stock and grafting seedling, aligned and combined together, making careful management so as to implement its grafting work.

The invention relates to a double-layer temperature-sensitive gel microsphere and a preparing method thereof. The double-layer temperature-sensitive gel microsphere and the preparing method are characterized in that: the double-layer temperature-sensitive gel microsphere adopts medicinal sodium hyaluronate and chitosan as gel raw materials, and comprises a chitosan gel core and a sodium hyaluronate gel shell. The inner layer of the gel microsphere contains the chitosan, so that the gel is compression-resistant and degradation-resistant. The outer layer of the gel microsphere is covered with the sodium hyaluronate gel shell, so that the gel microsphere is liable to inject. The particle size of the gel microsphere is small and uniform, so that the gel microsphere is liable to dialyze. The gel microsphere has synergistic effects of the sodium hyaluronate and the chitosan, so that the repairing time for an injection part is prolonged and the gel microsphere is more liable to inject. The gel microsphere is characterized by being antibacterial, anti-coagulation and good in formability in organisms.
