Technical Field

[0001] The invention relates to the technical field of garden bonsai production, in particular to a method for cultivating stakes of fraxinus chinensis branches and trunks. Background Art

[0002] Fraxinus chinensis is a plant of the genus Fraxinus in the family Oleaceae, which is unique to China. Fraxinus chinensis is a tall deciduous tree with a straight trunk and excellent material. It has an elegant posture, beautiful tree shape, small and beautiful leaves, verdant leaves, dense branches, vigorous growth, strong germination ability, resistance to leaf picking and pruning, excellent shape, and high ornamental value. It is a beautiful garden greening tree species and the best material for world garden landscaping and bonsai production. It is known as the "King of Bonsai". Well-cultivated Fraxinus chinensis garden trees, pile landscapes, and root carvings are very valuable. Due to the extremely high economic value of large-scale bonsai and landscape trees of Fraxinus chinensis, there has been a predatory act of stealing and digging wild Fraxinus chinensis trees among the people for many years, which has caused irreversible damage to the existing wild Fraxinus chinensis resources and seriously hindered the sustainable development of the Fraxinus chinensis forestry industry.

[0003] The existing experimental planting of Fraxinus chinensis has not achieved satisfactory results. The ability of the thick branches of Fraxinus chinensis to sprout new roots is poor, resulting in a low survival rate of planting. Therefore, on the basis of protecting the existing native population of Fraxinus chinensis, it is of great practical significance to explore a method to cultivate thick branches of Fraxinus chinensis in a short period of time that can be directly used for large and medium-sized bonsai or landscape trees.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] The present invention provides a method for cultivating stakes of Fraxinus chinensis branches and trunks, comprising the following steps:

[0028] (1) Cutting pile materials

[0029] Before the sap starts to flow in spring, the Fraxinus chinensis stakes are cut in combination with the pruning and shaping of Fraxinus chinensis bonsai gardens or artificial forests. The Fraxinus chinensis stakes are Fraxinus chinensis stem segments with a diameter of more than 10 cm and bonsai or landscape modeling value, which are suitable for cultivating stakes with thick branches of Fraxinus chinensis. Piles with a trunk diameter between 10 cm and 20 cm are medium-sized piles; piles with a trunk diameter greater than 20 cm are large piles.

[0030] (2) Piles soaked in water

[0031] Fill a large vat with water and immerse all the pile materials obtained in step (1) in the water to allow them to fully absorb water and return to normal as soon as possible. The soaking time is determined by the time the outer skin of the pile materials turns green. During the soaking process, timely observation is required.

[0032] (3) Rooting treatment

[0033] After the surface of the soaked pile material turns green again, take out the pile material and treat the base of the pile material with a rooting agent. The base of the pile material is evenly coated with the rooting agent. There are two types of rooting agents: powder and water, as follows:

[0034] As one of the specific embodiments, the rooting agent includes sodium naphthalene acetate, boric acid and vitamin B1 in a mass ratio of (1.5-3):1:(0.02-0.03); sodium naphthalene acetate, boric acid and vitamin B1 in a certain proportion are mixed and stirred evenly, ground into powder, and a powdered quick-dip rooting agent is prepared. When in use, the base of the pile material is evenly dipped with the powdered rooting agent, that is, the base of the pile material is evenly dipped with a layer of powdered rooting agent.

[0035] Preferably, the rooting agent comprises sodium naphthaleneacetate, boric acid and vitamin B1 in a mass ratio of 2:1:0.02, which are uniformly stirred and then ground into powder using a roller. To improve the uniformity of the particles, the powder can be sieved.

[0036] As one of the specific implementations, the aqueous rooting agent is an IBA solution (i.e., indolebutyric acid), and the concentration of the IBA solution is 90-220 mg / l. The base of the medium-sized pile is treated with a prepared 200 mg / l IBA solution, and the large pile is soaked in a prepared 100 mg / l IBA solution for 60 minutes to ensure that the pile takes root smoothly in the later stage.

[0037] (4) Piles

[0038] After disinfecting the cultivation medium, make a nursery, and plant the piles treated with rooting agent with the base facing downwards into the cultivation medium, with a planting depth of >20cm. When arranging the piles, the distance between medium-sized piles should be >0.5m, and the distance between large piles should be >1m. After arranging the piles, water them sufficiently to ensure that the branches and trunks are closely combined with the medium.

[0039] Preferably, the cultivation substrate may be coarse river sand or a prepared light substrate, wherein the light substrate comprises peat and perlite in a volume ratio of 1:1 to 6:4, and the peat and perlite are mixed evenly before use.

[0040] Preferably, the volume ratio of peat to perlite is 1:1 or 6:4.

[0041] Preferably, before use, the cultivation medium is sprayed with 5‰ potassium permanganate solution for disinfection, then covered with a film and sealed for 3 to 5 days, and then the film is removed to make a bed.

[0042] (5) Shade and moisturize

[0043] Shade the nursery after the piles are arranged in time, and use a shade net with a shading rate of 30% to 50%. At the same time, spray water every day depending on the dryness and wetness of the tree trunks to keep them green and moisturized until the piles take root.

[0044] (6) On-site maintenance

[0045] After rooting, the stumps are maintained in situ for one year, and water management is carried out during the maintenance process; shade is removed in early August, and sufficient sunlight is exposed, and fertilizers are applied in time from June to September.

[0046] Specifically, during the maintenance process, keep the nursery moist and water the trunk frequently. Remove the shade net in early August and expose the pile to sufficient sunlight. Apply thin fertilizer frequently from June to September, once a week, to ensure that the pile has sufficient nutrients.

[0047] Preferably, by early May of the following year, if there are still unsprouted piles in the nursery, scrape the top bark to see that it is emerald green, and pull them out, soak them in water again and maintain them to promote their germination and survival. Steps 2-7 can be repeated.

[0048] (7) Plastic pelvic floor surgery

[0049] After the leaves fall in the autumn of the following year, dig out the stumps, shake off the sand, cut off the excessively long roots, trim the branches, use loose, fertile, well-drained loam as the potting soil, shape the plant and plant it in the pot. After planting, water it enough to help it take root.

[0050] In view of the current situation that wild Fraxinus chinensis resources are seriously damaged and the resources are in urgent need, the present invention utilizes the thick branches cut off during the daily pruning of Fraxinus chinensis artificial forests and formed pile landscapes, and through the above-mentioned pile cultivation method, cultivates Fraxinus chinensis thick branch seedlings that can be directly used for making large and medium-sized bonsai or landscape trees in a short period of time, which not only greatly shortens the cultivation time of Fraxinus chinensis bonsai and landscape trees, provides technical guarantee and technical support for the rapid formation and listing of large-pile bonsai, but also creates a new path and new method for the protection of Fraxinus chinensis resources in Jingshan City, Hubei Province.
