The invention discloses a method for increasing the emergence rate of hemsleya amabilis seeds. The method includes the steps of seed fine selection, seed processing and storage, seed processing before sowing, seedbed preparing, sowing and seedling culture field management. The seeds and wet river sand are evenly mixed, contained in a sand bag and stored in a refrigerator at the temperature of 1-6 DEG C; before sowing, the seeds are placed indoors for 1-2 days at the temperature of 15-18 DEG C after the river sand rubs seed husks, germination acceleration is conducted in an artificial climate cabinet, the temperature is 20+ / -1 DEG C, illumination time lasts for 10-12 hours, light intensity is 2000lx, and the water content of the river sand is 10-13%; leaf mold and organic fertilizer are added into a seedling culture field soil tillage layer, bactericide is sprayed on the surface of a seedling culture field, a seedbed is ditched, mixed substrates are placed in ditches, topdressing is carried out once in early July and late August in the sowing year, and after sprout tumble in October, the surface of the cabinet is covered with farmyard manure; compound fertilizer is applied in early July and late August in the second year, the emergence rate of the hemsleya amabilis seeds is over 80%, emergence time is short, and seedlings are orderly and strong.

The invention discloses a method for fast transfer of large yellow croaker fry. The 40-50-day-old large yellow croaker fry grown indoors and with a total length of 2.5-4.0 cm are used to align a flashlight with a flashlight at the drain end of a seedling pond and use its characteristics of phototaxis and clustering. Cover the other parts of the seedlings with black cloth, so that the large yellow croaker fry are concentrated in a small corner of the illuminated drainage end, and the siphon tube is used to siphon the clustered seedlings into the water body of the seedling cabin of the live water boat with oxygenation or directly transfer them to the sea. At the same time, in the process of siphoning, the water inlet of the nursery pond adopts the flowing water method to keep the water level of the nursery pond unchanged, and siphon most of the fry in the nursery pond to emerge until it is difficult for the fry to cluster.

The invention discloses a method for breeding kiwi fruit finished product seedlings in a greenhouse by using nutritive bowls. The method includes: seed collection, sandy storage, seedling heating bed laying, arc shed construction, sowing, seedling stage management, young seedling transplanting, nutritive bowl changing, and grafting. Seed selection can allow strong germination force of seeds, the emergence time is fast, the emergence rate and the evenness of the seedlings are better than that of variety seedlings, and the good seeds can ensure the whole quality of later seedlings; greenhouse nutritive bowl seedling cultivation can promote growth of the seedlings of the kiwi fruits during a seedling stage. The method is even in seedlings, is short in seedling cultivation period, is high in yield, is high in transplanting survival rate, is simple in technology, facilitates large-scale industrialized production, and has important practical significance for rapid large-scale seedling cultivation of the kiwi fruits.

The invention discloses a simple efficient cultivation method for raising seedlings of Mesembryanthemum crystallinum L.. The method comprises the steps of: immersing seeds of Mesembryanthemum crystallinum L. until the seeds is whitened before sowing is conducted; filling holes of a seedling raising tray with a mixed substrate of turfy soil and sand loam and vermiculite from bottom to top sequentially, wherein the filling volume of the mixed substrate accounts for 3 / 5-4 / 5 of the volume of the holes, and the filling volume of the vermiculite accounts for 1 / 5-2 / 5 of the volume of the holes; pouring the substrates with atomized water, taking germinated seeds to centers of the holes through absorption, and after sowing is conducted, putting the seedling raising tray in an backlight environmentwhich has a temperature of 20-25 DEG C, a relative humidity of 60-80% and an air velocity of less than 0.5-1 m.s<-1>, wherein no covering of surfaces of the seeds with arbitrary substrates is needed;and when the seedlings of the seeds emerge 2-3 days later, and after the surface of the substrates is dry, performing spraying by using the atomized water. Through the substrates and the arrangement relationship of the substrates, roots of Mesembryanthemum crystallinum L. are promoted before and after the seedlings emerge, the emergence rate is improved greatly and can reach 95% or above, the emergence time is short and can be 2-3 days, and no seedling thinning and two-time seedling transplanting are needed, so that the cost is saved greatly.

The invention provides a production method of Zanthoxylum bungeanum, comprising the following steps: (1) harvesting follicles at the full maturity stage; (2) storing the follicles at low temperature and avoiding light; (3) removing the peel of Zanthoxylum bungeanum before sowing, And soak it with a solution of 6-benzylaminopurine and gibberellin; (4) The sowing substrate is peat charcoal that has been sterilized. After sowing, the ambient temperature is 20°C and 35°C alternately for 12 hours each, and the air humidity is 60% to 80%. Until the seeds germinate; (5) After the seeds start to germinate, the daytime treatment conditions are: temperature 28-32°C, light intensity 6000-8000lx, 12h; night treatment conditions are: temperature 23-27°C, dark, 12h; Harvest when 4~7cm. The invention maintains the exuberant vitality of Zanthoxylum bungeanum seeds and avoids dormancy; the seeds germinate quickly, the emergence time is short, and the seedlings emerge neatly, so as to achieve the purpose of producing Zanthoxylum bungeanum seedlings in a short period of time, and solve the industrialized production of Zanthoxylum bungeanum buds key technical bottlenecks.

The invention discloses a cutting and breeding method for tree stocks of Populus tremula * P. tremuloides, comprising the following steps: preparing a slotter, manufacturing cuttingwood, processing, cutting, managing after cutting, transplanting and planting in field, wherein in the step of manufacturing the cuttingwood, the current-year semi-lignified twigs of the Populus tremula * P. tremuloides are collected from March to May every year to serve as cutting, simple-ink single-leaf stalk sections are cut from the cuttings to serve as the cuttingwood. When the method of the invention is adopted for cutting and breeding the tree stocks of the Populus tremula * P. tremuloides, callus grows on the cuttings one week after cutting; roots begin to grow after 12 days; and after 18 days, the average length of the roots reaches 6.5cm, the average diameter of the roots reaches 0.18 cm, and the rooting rate reaches above 80%. The method of the invention improves the cutting survival rate of the Populus tremula * P. tremuloides to a greater degree; and in addition, the method of the invention also has the advantages of short emergency time, high rooting rate, simple and easily controlled technology, low breeding cost and the like.
