Guava leaf-bud cutting propagation method

The invention provides a guava leaf-bud cutting propagation method. The method comprises the following steps of 1, selecting nutrient soil, adding ardealite ganister sand into the nutrient soil per cubic meter and placing the mixture into a container for use after stirring is performed, wherein the nutrient soil is smashed red earth or the mixture of coco coir and peat soil; 2, building a cuttagegreenhouse, and placing the container with the nutrient soil into the greenhouse; selecting guava branches as a cuttage material, and soaking the branches with a rooting solution and then performing cuttage in a plastic cup, wherein the preparation method for the rooting solution comprises the step that indolebutyric acid and bone meal are added into per kilogram of water to be mixed to be uniformto obtain the rooting solution. According to the guava leaf-bud cutting propagation method, due to the rooting solution prepared from indolebutyric acid and animal bone meal, root growth and development are promoted. The principle that rooting is promoted due to the fact that green branch cuttage is performed for manufacturing a carbon source by means of the green leaf photosynthesis is utilized,and the method has the advantages that rooting seedling formation is promoted, the seedling growing period is shortened, operation is easy, nursery stock grows rapidly and the cost is low.

Finishing mucilage capable of forming thick coating on surface of EPS (Expandable Polystyrene) plate and preparation method of finishing mucilage

The invention provides a finishing mucilage capable of forming a thick coating on the surface of an EPS (Expandable Polystyrene) plate and a preparation method of the finishing mucilage, belongs to building materials, and overcomes the defects that the conventional finishing mucilage is low in bonding strength, is easy to crack, cannot form a thick coating, and is difficult to meet the fire-proof requirement. The finishing mucilage is prepared by mixing limestone powder, ganister sand, cement, a PP (Propene Polymer) fiber, a wood fiber, a modifying agent, a water repellent and water. The finishing mucilage capable of forming the thick coating on the surface of the EPS (Expandable Polystyrene) plate and the preparation method of the finishing mucilage have the positive effects that the bonding tensile strength of a mucilage layer and a benzene adhesive plate exceeds 0.1 Mpa. The cost of the finishing mucilage is lowered by about one third. The expansion and contraction deformation of the finishing mucilage generated under the influence of external natural conditions can be better absorbed, and the temperature difference deformation stress is dispersed around uniformly, so that the generation of cracks is effectively prevented. The thicknesses of external thermal insulation protecting layers can respectively reach 13 mm, 18 mm, 23 mm, 28 mm and 33 mm through adjusting the formula and the construction process and the like.
