Moisture-retention sustained and controlled release fertilizer and method of preparing the same

The invention discloses a water holding slow-controlled releasing fertilizer and a preparation method thereof, belonging to the technical field of agricultural fertilizers and preparation thereof. Macromolecule coating fertilizer is taken as an inner core and a water holding layer is taken as an outside layer to form a double-coating water holding slow-controlled releasing fertilizer; an inner coating is macromolecule protective layer coating material with nutrition controlling and releasing property; an outside coating is the water holding layer with excellent water holding property. Water retention agent suspension liquid is sprayed to the surface of macromolecule coating fertilizer grains for outside coating; wherein the water retention agent is prepared by taking cyclohexane, emulsifier, acrylic acid, acrylamide, sodium hydroxide, cross linker and evocating agent and adopting the method of opposite phase suspension polymerization. The fertilizer has the function of controlled releasing, drought resistance, water saving, water holding and soil improving and the advantages of high absorption percentage, wear resistance, difficult falling and the like; utilization ratio of liquid manure is improved and the fertilizer can be widely used to desert control, lawn plant, soil improvement, gardening, agriculture and forestry and the like.

Colorful ceramic and preparation method thereof

The invention provides colored ceramics and a preparation method thereof. Ceramic mud for the colored ceramics at least comprises the following compositions in weight percentage: 20 to 35 percent of kaoline, 60 to 70 percent of at least two of pottery stones, lithium pottery stones, feldspar and quartz, 0.2 to 6 percent of coloring matter, and 1 to 5 percent of nanometer quartz. The method for preparing the colored ceramics comprises the following: a step of pulp injection molding, in which part of colored mud cake or colored mud strip is mixed with liquefacient with 0.3 to 0.8 percent of total amount for pulping, and the mud which is screened from a screen of between 80 and 120 meshes is injected into a mold to produce a hollow or solid briquette; and a step of glazing and maturing, in which the briquette which is manufactured by pulp injection molding or plastic molding is cemented and dried according to creativities, and are directly applied with clear glaze, and the glazed briquette body is placed in an oxydizing flame roller kiln or an electrical kiln for 1 to 4 hours at a temperature of between 1,150 and 1,200 DEG C for maturing. The method can not only reduce clinkering cost, but also improve the moisture retention, bonding performance and corrosion resistance of strong ceramic mud, and further show energy conservation and environmental protection.
