The present application relates to the technical field of artificial feeding of small insects, in particular to rubberwood small insects rubber tree wood chip cultivation feed and artificial feeding method. The rubberwood small insect cultivation feed comprises yeast powder, weiss salt, casein, starch, sucrose, agar powder, streptomycin sulfate, wheat germ oil, anhydrous ethanol, rubber tree wood chip and deionized water. The rubberwood small insect feeding method comprises the following steps: obtaining rubberwood small insect female adults; inoculating rubberwood small insect female adults; and feeding rubberwood small insects in a climate box. The artificial feeding method of rubberwood small insects provided by the present application can obtain stable test insect sources, provide insect source guarantee for studying the biological and ecological characteristics of rubberwood small insects, and further lay a theoretical foundation for formulating rubberwood small insect prevention and control measures.

This invention belongs to the technical field of building decoration materials and relates to a digitally printed rubberwood finger-jointed core flooring. It includes a core layer, on the surface of which, from top to bottom, are a coating layer, a printing layer, a primer layer, a top layer, and a first balancing layer. Below the back of the core layer are a second balancing layer and a backing board. The core layer is made of rubberwood finger-jointed material, joined by finger-joints along the length of rubberwood strips and spliced ​​along the width. Stress grooves are provided on the surface of adjacent rubberwood strips away from the finger-joints. The width of the stress grooves is 0.5–0.6 mm, the depth is 1.0–2.0 mm, and the length is between the width of one and two rubberwood strips. The distance between two adjacent stress grooves is not less than 0.2 mm. The thickness of the printing layer is 0.01–0.1 mm. The production process is also disclosed. This invention controls structural stability through structural adjustments, making it less prone to deformation and cracking; the combination of paint coating and digital printing fully utilizes low-grade wood raw materials.
