The invention discloses a method for callus induction and adventitious bud differentiation of quercus variabilis. The method for callus induction and adventitious bud differentiation of the quercus variabilis adopts the test-tube seedlings obtained by aseptic seeding induction of quercus variabilis seeds as test materials. When the seedlings are 3-6 cm tall and the roots are 1-1.5 cm long, the root systems of the seedlings are subjected to girdling with an aseptic blade and placed in induction mediums for callus induction, then the induced callus is stripped from the root systems, and callus proliferation, adventitious bud differentiation induction and adventitious bud rooting are carried out. The method for callus induction and adventitious bud differentiation of the quercus variabilis adopts the root systems of the girdled seedlings for callus induction culture, and finally obtains the seedlings through the process of callus proliferation, differentiation culture and the like, so that the problems, in the conventional quercus variabilis tissue culture process, of difficult induction of embryogenic callus with stem tips, stem segments and leaves and serious endophyte contaminationof the culture material are solved, the adventitious bud propagation coefficient can be increased, and the method for callus induction and adventitious bud differentiation of the quercus variabilis has practical significance for the large-scale seedling raising of the quercus variabilis.

The invention relates to a method for cultivating cork oak seedlings. The method comprises the steps of collecting and storing seeds, selecting a seedling cultivating field, regulating a seedling bed, preparing seedling cultivating soil, processing the seeds, soaking the seeds in rooting powder, hand sowing in a nutrition pot, spraying rooting powder solution, lifting and transplanting the seedlings and the like. According to the method, through excellent cork oak forest stand or superior tree seed collection, and as the rooting powder is used for soaking the seeds and the prepared soil, and the rooting powder solution is sprayed for two times, the root length of the seedling which is cultivated for 1-2 years is increased by 30%, and the number and length of rootlets are respectively increased by 40%-30%. The seedling cultivating cost is lowered by 30%. The survival rate of cork oak afforestation by seedlings reaches 85%-90%.

The invention discloses a DNA (Deoxyribose Nucleic Acid) bar code standard detection gene of triphophysa siluroides and application of the DNA bar code standard detection gene. The DNA bar code standard detection gene is a COI gene, with the nucleotide sequence shown as SEQ ID NO.1. A DNA bar code species identification method of the triphophysa siluroides adopts a reliable DNA molecular identification technology and the triphophysa siluroides is rapidly and accurately identified. Compared with a traditional morphological identification method, a standard gene sequence obtained by the method is good for molecular identification of the triphophysa siluroides and identification time can be effectively shortened.

The invention discloses a cylinder-driven folding-curtain water regulating mechanism. The water regulating mechanism comprises a sleeve, a limiting support, an air regulating mechanism, a cylinder block, a piston, a sliding chute, a sliding block, a self-folding water-blocking curtain, a folding curtain guide stopping unit and two blocking bulges, wherein the sleeve is a cork oak cork wood pipe which is circular externally and square internally; the sleeve is internally provided with the limiting support; the cylinder block is embedded in the rear end of the limiting support; the cylinder block is internally provided with the piston; the sliding chute is formed in the rear end of the cylinder block; the sliding chute is internally provided with the sliding block capable of sliding up and down only; the sliding block and the piston are connected together through attractive force; the folding curtain guide stopping unit is arranged at the rear end of the sliding block; the self-folding water-blocking curtain is a water-blocking curtain of a wavy structure; and the upper end and the lower end of the self-folding water-blocking curtain are connected with the inner wall of the upper endof the sleeve and the folding curtain guide stopping unit respectively. Compared with the prior art, the water regulating mechanism can meet the requirement that the water diversion plug outflow water quantity is continuously and effectively regulated, is simple and convenient in operation, natural and environmentally-friendly, and has a certain health care effect.

The invention belongs to the technical field of wood processing, in particular to a processing method of a cork oak bark yoga column. Firstly, the bark of cork oak is picked and peeled, impurities are removed, unfolded while wet, stacked, flattened by weights, air-dried and cut into boards and sanded; secondly, the cork oak bark is vertically arranged and sprayed with hot water and dried; The bark board is coated with floor glue on both sides, and hot-pressed to form a cork oak bark wooden square; again, the wooden square is cut into a round bar, and the outer surface of the round bar is engraved with a pineapple roll pattern; finally, the round bar is Send it to a drilling machine, drill through holes, use a turning tool to chamfer the two ends of the round bar, sand the inner and outer surfaces of the cork oak pineapple roller with sandpaper, remove dust, and paint to make a cork oak bark yoga column . The invention is simple and easy to implement, the yoga column has the characteristics of light weight, rich cushioning elasticity, environmental protection and no toxicity, can help yoga practitioners to complete various balancing actions, and can eliminate muscle tension and strengthen core muscle strength.
