Underyearling semi-lignified and robustly growing castanopsis hystrix tender branches are collected as explants, the explants are inoculated into an initial bud induction medium after being treated by trimming and sterilization and disinfection treatment to acquire initial buds, then the initial buds are inoculated into a proliferation medium to carry out proliferation culture for 3-4 cycles to form multiple bud clusters, the multiple bud clusters access to a strong bud medium to be cultured, and finally, single buds with height being larger than or equal to 2cm are inserted into a rooting medium to be induced to grow roots. According to the castanopsis hystrix tender branch tissue culture and propagation method, the castanopsis hystrix seedling cycle is shortened, a seedling material is saved, the problems that the amount of materials needed by seedling is more, the cycle is long and the like in the traditional seedling method are overcome, the production cost is greatly lowered, the production efficiency is improved, and the castanopsis hystrix tender branch tissue culture and propagation method has better economic benefit, social benefit and ecological benefit.

Cross breeding method capable of increasing fruiting rate of castanopsis hystrix
ActiveCN106035063AImprove fruit setting rateImprove seed qualityPlant genotype modificationFruit setAnimal science
The invention discloses a cross breeding method capable of increasing the fruiting rate of castanopsis hystrix. The cross breeding method comprises the following steps: S1, a female parent is subjected to castration and bagging; S2, when male flowers of a male parent are in the transitional period from an initial flowering period to a full-bloom period, male inflorescence of the male parent is collected and dried; S3, artificial pollination is performed: when stigmas of female flowers of the female parent are rolled reversely at the angle ranging from 40 degrees to 50 degrees, bags are removed on a sunny day, dry male flower pollen is sufficiently scattered on the stigmas of the female flowers from 9:00 to 10:30, and then bagging is performed; S4, the stigmas of the female flowers do not have mucus or get black 3-5 days after pollination, the bags are removed, the female flowers are exposed and grow naturally, and cross-bred seeds are obtained when green cones turn brown. With the adoption of the castanopsis hystrix cross breeding method, the fruit setting rate of castanopsis hystrix can be remarkably increased, the seed quality can be remarkably improved, the pollination success rate and the fruiting rate of castanopsis hystrix are increased efficiently, and besides, the method is simple to operate, easy to control and stable in effect. The cross breeding method has great significance in solving of the problem about lack of certified seeds of castanopsis hystrix.

Method for obtaining large-batch high-quality explants by castanopsis hystrix branch bending and germination promotion technology and application thereof
ActiveCN112889567AIncrease success rateSolve the bottleneck of reproductive difficultiesGrowth substratesCulture mediaCastanopsis hystrixGermination
The invention discloses a method for obtaining large-batch high-quality explants by a castanopsis hystrix branch bending and germination promoting technology and application thereof. The method comprises the steps of matrix treatment, pruning treatment, field planting, branch bending, soil covering, germination management and the like. According to the method, a branch bending and germination promoting mode suitable for castanopsis hystrix is established through experimental research on a bent branch culture medium, a branch pruning method before branch bending, a branch bending method and the like, the number and quality of the castanopsis hystrix explants can be remarkably improved, the problem that the number of high-quality castanopsis hystrix explants is insufficient can be effectively solved, and feasible theoretical basis and technical support can be provided for preparation of rejuvenized explants through vegetative propagation.

Manufacturing method of wooden drum
ActiveCN109559715AReduce crackingDrum cavity echo effect is goodPercussion musical instrumentsEngineeringUltimate tensile strength
The invention discloses a manufacturing method of a wooden drum. The manufacturing method comprises the following steps: S1, soaking peach wood and castanopsis hystrix wood, carrying out airing, carrying out firing, thus obtaining a core material, soaking the core material, carrying out drying, and carrying out saw cutting to obtain peach wood boards and castanopsis hystrix wood boards; S2, soaking the peach wood boards and the castanopsis hystrix wood boards, and carrying out natural airing, wherein the peach wood boards serve as the main board blocks, and the castanopsis hystrix wood boardsserve as the auxiliary board blocks; S3, splicing the main board blocks and the auxiliary board blocks to form a drum body, and wrapping the drum body with a cloth material; S4, covering the inner wall of the drum body with a metal layer; S5, soaking cattle hide, thus obtaining cattle hide after blood removal; S6, airing the cattle hide after blood removal, thus obtaining half-dry cattle hide; S7,drying the half-dry cattle hide to obtain dry cattle hide; S8, carrying out standing treatment on the dry cattle hide, thus obtaining drum leather; S9, arranging a vibrating increasing device in thedrum body; S10, strutting the drum leather by using a loop, thus forming a drum head; and S11, sleeving the loop in two ends of the drum body, thus obtaining a Zhuang drum. In the manufacturing methodof the wooden drum provided by the invention, the metal layer attaches to the inner wall of the drum cavity, so that the echo effect of the drum cavity is good, the resonance strength is high, and the sound is loud enough.

Castanopsis hystrix afforestation pruning method
PendingCN114711116AIncrease valuePromote growthClimate change adaptationAfforestationSoil scienceCastanopsis hystrix
The invention provides a castanopsis hystrix afforestation pruning method, and belongs to the technical field of garden management. The castanopsis hystrix afforestation pruning method comprises the steps that after afforestation is conducted for 4-5 years, pruning is conducted when the plant height of castanopsis hystrix reaches 6-7 m, the pruning amplitude is 1 / 4-1 / 2 of the crown length, and after pruning, a cut is smeared with a protective agent. According to the method, based on the research on adult single-plant wood knot scar distribution, the formation of wood knot scars is reduced through a pruning mode in the early growth stage, so that the wood income is improved; investigation on tree growth and scar healing conditions after pruning shows that reasonable pruning and protection measures are crucial to reduction of scar formation and improvement of the roundness of a trunk.
