The invention discloses a coumarin synthetic gene in black bamboo and application thereof, and belongs to the technical field of molecular biology. The invention provides transcription factors PnMYB4 and PnMYB4-1 for promoting synthesis of coumarin in black bamboos and application of the transcription factors PnMYB4 and PnMYB4-1. The PnMYB4 and the PnMYB4-1 belong to an MYB transcription factor family, the length of a complete coding frame of the PnMYB4 is 762 basic groups, and the coded protein contains 253 amino acids; the length of a complete coding frame of the PnMYB4-1 is 744 basic groups, and the coded protein contains 253 amino acids. The coumarin substances in arabidopsis thaliana, which are respectively overexpressed by PnMYB4 and PnMYB4-1, are obviously increased, and in addition, the expression levels of coumarin synthetic genes such as AtPAL1, At4CL1 and AtC4H in overexpressed plants are obviously increased.

The invention discloses an anti-cracking and mildew-proof composite bamboo cutting board and a manufacturing method thereof, and belongs to the technical field of bamboo cutting board manufacturing, the bamboo cutting board comprises a cutting board body formed by alternately attaching and arranging white bamboo blocks and black bamboo blocks, and bamboo fibers prepared from bamboo processing waste are mixed in bamboo glue; the bamboo fibers are prepared by processing leftover materials generated in the procedures of cutting, carbonizing and cooking bamboo blocks and bamboo green / tabasheer planing waste materials; the chopping board body is provided with a deep nourishing protective layer and a surface compact protective layer. The manufacturing method comprises the steps of raw material pretreatment, composite forming, mould-proof and anti-cracking strengthening treatment and later processing. In the raw material pretreatment process, bamboo fibers are prepared through the steps that bamboo green / tabasheer planing waste is subjected to hot water extraction to prepare bamboo green antibacterial liquid; the leftover materials are crushed and dried and then soaked with a mixed solution of a silane coupling agent solution and a bamboo green antibacterial solution, and antibacterial modification is achieved; and after airing, soaking with an epsilon-polylysine solution to realize antibacterial enhancement. According to the invention, waste reutilization and efficient and lasting mildew-proof and anti-cracking performance are realized.

The invention discloses a black bamboo charcoal-based degradable mulching film as well as a preparation method and application thereof, and belongs to the technical field of biodegradable materials. The mulching film is composed of poly (butylene adipate-co-terephthalate) (PBAT) and bamboo charcoal powder, and the bamboo charcoal powder is obtained by carbonizing bamboo powder. The core of the invention is that the technical bottlenecks that the original bamboo powder is strong in hydrophilicity, difficult to crush and poor in compatibility with PBAT are solved by utilizing carbonization modification, so that the use of color master batch and a coupling agent is omitted at the same time, and the cost is remarkably reduced. The prepared black mulching film not only has excellent mechanical properties, but also has multiple synergistic functions of blocking and preserving soil moisture, far infrared heating, shading and preventing weeds, improving soil, fixing carbon and the like, is an efficient and environment-friendly solution of replacing plastic with bamboo, and is suitable for the fields of agriculture and the like.

The application discloses a kind of anti-cracking mould-proof composite bamboo chopping board and manufacturing method thereof, belong to bamboo chopping board manufacturing technical field, bamboo chopping board includes by white bamboo block and black bamboo block alternative adhesion arrangement and becomes anvil plate body, and bamboo fibre prepared by bamboo processing waste is mixed in bamboo cement;Bamboo fibre is made by corner waste and bamboo green / bamboo yellow shaving waste after processing in bamboo block cutting, carbonization, cooking procedure;Anvil plate body has deep layer nourishing protective layer and surface dense protective layer.Manufacturing method includes raw material pretreatment, composite forming, mould-proof anti-cracking strengthening treatment and later processing procedure;In raw material pretreatment procedure, bamboo fibre preparation is: bamboo green antibacterial solution is prepared by bamboo green / bamboo yellow shaving waste hot water extraction;Corner waste is soaked after crushing, drying with the mixed solution of silane coupling agent solution and bamboo green antibacterial solution, realizes antibacterial modification;After airing, soak with ε-polylysine solution, realizes antibacterial strengthening.The application realizes waste recycling and efficient and durable mould-proof anti-cracking performance.
