The invention discloses an album page optimizing agent and a preparing method thereof, relating to the field of a painting and calligraphy article. The album page optimizing agent is characterized by being prepared from raw materials in parts by weight: 4.8-5.2 parts of strong flour, 24-26 parts of tap water, 0.9-1.1 parts of a cleaning agent and 0.4-0.6 part of radix stemonae. The album page optimizing agent is painted and coated on secondary-quality Chinese art paper, and is aired and cut to prepare a good-quality album page. According to the album page optimizing agent and the preparing method thereof disclosed by the invention, raw materials are easily available and the preparation is easy; after being optimized, the secondary-quality Chinese art paper has the performance of good-quality Chinese art paper and strong insect resistance; an album page manufactured by secondary-quality Chinese art paper can averagely save money when being compared with the album page manufactured by the good-quality Chinese art paper; and the album page optimizing agent and the preparing method thereof disclosed by the invention are obvious in economic benefits and have a wide popularization prospect.

The invention discloses selenium-rich and disease and pest resistant compound fertilizer. The selenium-rich and disease and pest resistant compound fertilizer is prepared from the following raw materials: monopotassium phosphate, controlled release nitrogen, grass carbon, soybean meal, sasanqua cake, rapeseed meal, amino acid, zinc sulphate, copper sulphate, ferrous sulphate, borax, 5- nitroguaiacol sodium salt, SiO2 soil improvement agent, selenium-rich yeast, alpha-pimacol, VB, VC and citric acid. The selenium-rich and disease and pest resistant compound fertilizer is scientific and rigorous in formula and is biofertilizer with selenium nutrition, resistance to disease and pest and pollution-free (low residue) effect, and a technology is scientific, organic, non-toxic, green and environmental-friendly. The selenium-rich and disease and pest resistant compound fertilizer can enhance a plant immunological function system, promote mobility of immune cells, regulate specific and non-specific immunological functions of a plant, effectively increase organic selenium content of the plant, realize a wound healing effect, rapidly promote new root development, cause the plant to be thick and strong, leaves to be thick, green, open and flat and root tubers and bulbs to be thickened and expanded, prevent premature senility and resist to cold, waterlogging, continuous cropping, salt and alkali.

The invention provides a rapid propagation method of hyacinth, which is characterized in that cue balls with well-developed root system of the base plate are selected, and the base plate is used as a plane, and the cue ball is rotated and cut from the inside of the base plate at an inclination of 30 degrees, and the mass content of sulfur is Spread 1% sulfur powder evenly on the cut of the cue ball, make the cut upward, and air dry for 2 to 3 hours under the sun at noon; place the cue ball in a well-ventilated cultivation room at 25°C, humidity below 50%, and cultivate and reproduce in dark When seed balls grow on the cue ball, peel off the seed balls and embed them in the substrate, store them at 25°C for 80-90 days for aestivation, take out the seed balls and plant them in well-drained sandy soil, and manage them as usual until the first day. Dig out the bulbs from June to July in the second year; store them in an environment of 25°C for 80 to 90 days, and then plant them again until the bulbs are dug out from June to July in the third year, and you can get flowering hyacinth bulbs. The reproductive efficiency of hyacinth is high. On average, each cue ball can reproduce 8-10 seed balls of uniform size.
