The invention discloses a method for growing cherry seedlings within one year through grafting and bough cottage. The method solves the problems that sweet cherry seedlings grow slowly, the grafting period is short, preserving rate is low after conventional grafting, the seedling growing time is long, and seedling commodity is low. The method includes the specific steps that (1), dormant scions of good cherry varieties are stored; (2), Gisela stock boughs are cultivated; (3), dormant buds of the good cherry varieties are grafted to the Gisela stock boughs; (4), the boughs are processed in an arch shed; (5), cottage of the boughs is carried out in the arch shed; (6), the boughs are managed after cottage; (7), cutting seedlings of the boughs are transplanted and managed. According to the method, the efficient good sweet cherry seedling growing technology is achieved, the grafting survival rate is more than 90%, the rooting percentage of bough cottage is more than 95%, the transplanting survival rate is more than 90%, and the seedlings are obtained within one year. The method has the advantages of being high in grafting survival rate, high in cottage rooting percentage, high in transplanting survival rate, short in seedling growing period and long in grafting duration, saving cost and the like.

The environment protection type bioactive plant-growing container for growing seedlings in planting consists of plant fiber powder 20-75 wt%, natural organic matter 10-60 wt%, bioactive nutrient 0.5-20 wt%, non-toxic adhesive 10-50 wt% and stuffing 3-10 wt%. The said plant fiber powder is husk powder, rice straw powder, corn straw powder, wheat straw powder, etc; the natural organic matter includes turf and sphagna; and the bioactive nutrient is algin. The plant-growing container is produced through mixing the said material and press molding at 80-160 deg.c.

The container seedling-raising device and seedling-raising method of the chrysanthemum chrysanthemum of the present invention, the chrysanthemum chrysanthemum container seedling raising device comprises a bottom shell, a seedling raising tray assembly, an upper frame and a conical guide tube, the upper frame is arranged on the top of the bottom shell, and the Protrusions are provided on the inner wall around the bottom shell, the bottom edge of the seedling tray assembly overlaps the protrusions on the inner wall of the bottom shell, and the edge of the conical guide tube is in contact with the upper frame. The four sides of the top are sealed and connected, and the method for cultivating seedlings in a container includes seed treatment, seed cultivation, seedling transplanting and nursery stock emergence. In the present invention, a closed space is formed by arranging the bottom shell, the upper frame and the conical guide tube, which can ensure that the ambient temperature and humidity are in a relatively constant state during seedling cultivation. The components cooperate with each other to realize the synchronous completion of water spraying and ventilation without the participation of external driving force, so as to achieve the purpose of automation and reduce the workload of staff.

The invention discloses an industrialized seedling raising method for cinnamomum camphora seedlings. The method comprises the following steps of 1, seedling hardening; 2, transplanting; 3, tray changing / bagging; 4, maintaining and managing. According to the industrialized seedling raising method for the cinnamomum camphora seedlings, tissue culture bottle seedlings are transferred to a 128-mesh tray or a 105-mesh tray for planting for 1.5-2.5 months after being subjected to seedling hardening, and then the tissue culture bottle seedlings are transferred to a 50-mesh forest tray or a nutritionbag to continue to be planted for 2.5-4 months, so that the seedling raising speed of the cinnamomum camphora seedlings is increased; the transportation cost of cinnamomum camphora is also reduced, cinnamomum camphora trees are easy to carry when planted on a mountain, and the planting survival rate of the cinnamomum camphora seedlings is also increased.

The present invention relates to a kind of aseptic rapid propagation method of black pine, the steps are as follows: (1) take black pine needle leaf base segment in spring as explant; (2) inoculate in MS culture medium+6-BA 2mg / L+NAA 0.05 mg / L to induce callus; (3) inoculate the callus on 1 / 2MS medium+NAA 0.05mg / L+PSK 0.001mg / L to realize its massive proliferation; (4) inoculate the callus Induce adventitious bud differentiation on 1 / 4MS medium+NAA 0.01mg / L+PSK 0.002mg / L; (5) Cut out the single bud and inoculate it in 1 / 2MS medium+NAA0.25mg / L+IBA0.25mg / L Induce rooting on L; (6) transplant the rooted small green seedlings to the matrix whose formula is 1 / 4 fine sand + 1 / 4 vermiculite + 1 / 2 humus after hardening for further growth. The invention proliferates the callus in a large amount in a short period of time, and then differentiates the callus to form regenerated shoots, so as to realize seed preservation and mass propagation of excellent black pine individuals.

The invention discloses a sunlight greenhouse seedling-raising method with which a Chinese angelica germination rate can be improved. The method comprises the steps of: (1) seed treatment; (2) seedbed preparation; (3) greenhouse controllability improvement; (4) sowing; (5) stem cutting and root insertion; and (6) seedling hardening. The method is characterized in that in the step (1), seeds are scrubbed by using arsenopyrite for removing seed wings, and are sprayed by using sterile water; the seeds are wrapped by using white cotton cloth for 1-2 days for regaining moisture; the seeds are subjected to ultrasonic processing for 30-50min; 0.35-0.40% alpha-sodium naphthylacetate is used for spraying, and the seeds are flatly paved in one layer on a filter paper; the seeds are wrapped by using the filter paper and are buried in composite nutritive soil for germination-promotion for 5-10 days; after germination-promotion, the seeds are sterilized by using 0.1g / L mercuric chloride for 5-6min, and are sterilized by using 0.1g / L sodium hypochlorite for 2-3min. In the step (5) stem cutting and root insertion, when seedlings grow to a height of 3-5cm, 1-1.5cm of aerial stems are cut, and the incisions are sterilized by using 0.1g / L mercuric chloride for 5-6min; the cut stem segments are adopted as female parents, and are transplanted into a germination medium for seedling-raising; and the stem cutting and root insertion seedling-raising step is circulated 2-3 times.

The invention relates to a rapid catalpa bungei cultivating method integrating grafting and cuttage. Catalpa ovata branches serve as stocks for heteroplastic grafting, cuttage is performed for seedling raising after catalpa bungei with xylems undergoes bud grafting. The rapid catalpa bungei cultivating method integrating grafting and cuttage is simple in operation, the stock utilization rate is high, the grafting and cuttage are not influenced by time, weather, environment, temperature and the like, the cuttage rotting rate is up to 100%, and the survival rate is up to 98% or above. The problems of slow catalpa bungei seedling breeding, short grafting period, low preserving rate after conventional grafting, long adult seedling cultivating time, low stock commodity and the like are solved, and accordingly the demand for a large number of fine catalpa bungei varieties, stocks and adult seedlings in the market. The seedling raising period can be shortened to be one year by adopting the method, the seedlings are orderly in height, the production cost is greatly reduced, the seedling raising speed is improved, factorized catalpa bungei production is achieved, and the economical benefit is remarkable.
