The present invention discloses a two-stage brewing method of black rice wine. Said method includes the following steps: pearling black rice to oblain rice polishes and polished rice, making the polished rice undergo the process of fermentation to obtain black polished rice fermented wine base for stand-by; baking black rice polishes, cooling, extracting the black rice polishes in rice wine, filtering to obtain rice wine richly containing anthocyanin and residue; making the residue undergo the processes of extrusion, puffing, pulverizing and saccharification treatment so as to obtain black rice oryzanal fermented wine base for stand-by; mixing two fermented wine bases, fermenting and extruding so as to obtain raw grains and clear wine, utilizing said raw grains to produce rice wine for stand-by, feltering and sterilizing the clear wine, finally, mixing said clear wine and above-mentioned all the rice wines and ageing so as to obtain the invented finished product black rice wine.

The invention discloses a microwave method for extracting red cabbage pigment, comprising the following steps that: purple cabbage is dried and crushed into 40 to 100 meshes, hydrochloric acid with a concentration between 0.20 and 0.50mol / L is added into the purple cabbage powder according to the solid-to-liquid ratio of between 1 to 8 and 1 to 20, the purple cabbage powder is immersed in the hydrochloric acid for 30 to 60 minutes, the microwave power is controlled to between 600 and 900W, the mixture is heated for 80 to 150 seconds, the product is taken out, cooled and filtered, the process is repeated for twice; the extracting solution is decompressed and condensed as well as is purified by a macroporous resin, is washed by water and is eluted by 30 to 70 percent ethanol; and the eluting solution is decompressed, condensed and dried so that the purple cabbage pigment product is prepared. The method has simple steps, and convenient and simple operation, accelerates the dissolution of the effective components by using microwave to heat, combines the macroporous resin to separate and purify, is not time-consuming and has high extracting efficiency. The obtained pigment product has high content of anthocyanin and good stability.

The invention belongs to the technical field of design of the formula of an agricultural fertilizer and particularly relates to a special compound fertilizer for lycium ruthenicum mill. The special compound fertilizer comprises the following ingredients: an organic fertilizer, microelements, a special compound microorganism bacterium agent and special algae fertilizer solution. The special compound fertilizer is applied four times every year, respectively comprising: first-time fertilization at the germination stage, second-time fertilization at the initial stage of ripening of bearing branch fruits, third-time fertilization at the later stage of harvesting of spring seven-inch branch fruits and fourth-time fertilization at the full-bloom stage of autumn seven-inch branch fruits; before fertilization each time, 2,000ml of the special compound microorganism bacterium agent for a saline-alkaline land and 2,000ml of the special algae fertilizer solution for the saline-alkaline land are diluted by 100 times and then are fully mixed with the microelements: 1kg of ammonium molybdate and 2kg of zinc sulfate, and the fertilizer can be used after the mixture is fermented for seven days. The special compound fertilizer is suitable for planting of the lycium ruthenicum mill in the saline-alkaline land.

The invention discloses a method for creating a high-anthocyanin horticultural ornamental poplar by utilizing miR156, and belongs to the technical field of plant genetic engineering. An overexpression vector is constructed by utilizing a precursor miR156b, the overexpression vector is transformed into poplar leaves through an agrobacterium-mediated method, and miR156 is overexpressed in the poplar. The expression quantity of miR156 of the obtained transgenic plant is remarkably increased, the anthocyanin content is remarkably increased, the plant is dwarfed, the leaves and branches are increased, and then the horticultural ornamental value of the poplar is improved.
