The invention relates to the technical field of agriculture, and discloses a method for increasing the emergence rate of fagopyrum tataricum seeds. The method comprises the following steps of extracting polysaccharides from a strain with the preservation number of CGMCC No.10101, then preparing a polysaccharide solution for soaking the fagopyrum tataricum seeds and dibbling the soaked seeds in a sowing season. According to the method, the fagopyrum tataricum seeds are pretreated by virtue of polysaccharides of endophytic fungi, so that the germination and emergence capability of the fagopyrum tataricum seeds is improved; the fagopyrum tataricum seeds are sown by virtue of a dibbling technology, so that the emergence rate of the fagopyrum tataricum seeds is increased; compared with an existing excessive sowing method for ensuring the emergence rate, the method has the advantages that the seeds are reasonable and uniform in density and the method is favorable for high yield of fagopyrum tataricum on one hand, and on the other hand, the sowing quantity and the production cost can be reduced and the method can be popularized and applied on a large scale.

The invention relates to a method for accelerating germination of Rhus chinensis seeds and belongs to the technical field of economic forests. The method comprises four steps as follows: seed storage,dewaxing, seed germination acceleration and sowing. According to structure and biological characteristics of the Rhus chinensis seeds, wax coats outside the Rhus chinensis seeds are removed by a slightly alkaline solution, and seed germination is facilitated; seed dormancy is broken by soaking with warm water, the seed germination is promoted, and emergence rate of the Rhus chinensis seeds is increased. The method has the characteristics of being scientific, reasonable, simple, high in operability and good in germination accelerating effect, can increase the emergence rate of the Rhus chinensis seeds scientifically and efficiently and is suitable for being popularized and applied to production.

The invention relates to an efficient propagation method of Dendrobium officinale, which comprises the following steps: (1) adventitious bud induction: culturing a sterilized Dendrobium officinale stem section in an induction culture medium for 28-30 days, wherein the induction culture medium is composed of 1 / 2 MS (Murashige-Skoog) basal culture medium, 0.5-0.8 mg / L naphthylacetic acid, 1.2-1.4 mg / L 6-benzylaminoadenine, 1.5-1.8 mg / L gibberellin and 25-30 g / L sucrose; (2) adventitious bud proliferation: after the induction is finished, cutting off the new bud growing at the internode of the stem section, inoculating into the induction culture medium to carry out subculture propagation for 30-32 days, and obtaining cluster buds at the cutting; and (3) sound seedling and root transplantation: cutting the cluster buds into single seedlings, transferring into a sound seedling culture medium to carry out sound seedling culture for 20 days, and carrying out rooting culture for 28 days after the buds develop into 2-3 blades which are 2-3cm high, wherein the sound seedling culture medium is composed of MS basal culture medium, 3 wt% sucrose, 0.7 wt% agar and 3 wt% organic fertilizer, and the rooting culture medium is composed of 1 / 2 MS basal culture medium, 0.3-0.5 mg / L naphthylacetic acid and 0.3-0.5 wt% activated carbon.
