Abstract
The invention discloses the method for a kind of pomegranate old branch cuttage Fast-propagation, select the age of tree to be the pomegranate tree of 25 ~ 35 years, 15 ~ 25 years old branches of life gathered on it are cuttings, after soaking with clear water, soak system with special efficacy rooting powder solution again, enter the peat composed of rotten mosses in annual late March cuttage: sand is that the ratio mixing of 1 ~ 1.5:2 ~ 3 is made in matrix by volume, mulch film in surface coverage, and make clip in cuttings expose mulch film wrapping moisturizing, enter the seedling management stage.The old branch cutting plantation of pomegranate of the inventive method breeding is up to 95%, and the method is simple to operate, and the cycle is short, and cost is low, instant effect, solves the technical barrier of the old branch cottage propagation of pomegranate, lays a good foundation for making the good potted landscape of sturdy primitive and crude Lao Zhuan.
Description
Technical field
The invention belongs to technical field of plant propagation, be specifically related to the method for a kind of pomegranate old branch cuttage Fast-propagation.
Background technology
Pomegranate (Punica granatum L.) has another name called pomegranate, is Punicaceae (Punicaceas) Punica (Punica) plant, belongs to machaka or dungarunga.Pomegranate is see the flowers seeds that flower sees fruit, is again the fruit tree be of high nutritive value, and have afforestation and the dual use of fruit cultivation concurrently, have economic worth, application is very extensive, has vast potential for future development.Meanwhile, pomegranate is with the favor of the fruit of its bright and colourful flower and bright red extremely people, and flower has single-lobe, polyphyll not; Pattern has bright red, look red, yellowish-white, red and white of stumbling; Fruit have large fruit, fruitlet point, have very high ornamental value throughout the year, no matter admire the beauty of flowers or see fruit, pomegranate all belongs to and makes bonsai good merchantable brand.But, utilize traditional epicormic branch cuttage method generally to need the time of 8-10 just can reach the effect making ancient stake potted landscape, there is the defect that growing-seedling period is long, often waste time and energy, do not reach again satisfied effect.Based on this, carry out pomegranate always dry old branch cottage propagation the ancient stake potted landscape of the pomegranate resources making of development and utilization preciousness is had great importance.
Pomegranate cuttage and seedling culture is that pomegranate choiceness utilizes in process, carries out the technical measures of Fast-propagation.More to the research report of pomegranate epicormic branch cuttage at present, Zhang Jimei etc. adopt raw semi-lignified then to study viewing and admiring pomegranate cuttage technique without the healthy and strong branch of damage by disease and insect, with the mixing formula 100mgL of IBA and NAA hormone
-1iBA+100mgL
-1the process rooting percent of NAA, soak time 0.5h is the highest, can up to 91.23%; What little brave grade adopts sturdy 1 year raw Cuttage of Punica granatum by Stiff Branches, and not treated, its survival rate can reach 95%; Zheng Guofu etc. utilize the hard branch that 1-2 is raw, have carried out the test of pomegranate cuttage and seedling culture in spring, survival rate more than 95%; Li Jian etc. adopt semi-lignified branch to do to insert Miho, study the impact on the numerous skill rooting rate of Fructus Fici tikouae cuttage of different cutting medium and different somatotropin and concentration, result of the test shows: No. 1 matrix cutting plantation is higher than No. 2 matrix, that is: concentration is that the NAA treatment effect of 0.5g/kg is best, survival rate 92%.
Main spray or the stiff branch of 1-2 of adopting of the research such as above-mentioned has carried out cottage propagation, and only have 2 sections of reports about the scientific paper that pomegranate old branch Technique on Cuttage Propagation is relevant is domestic, Han Jianqiu etc. utilize old branch (life in 5 years) cuttage to mention making Pomegranate bonsai and obtain successfully, but study report in great detail; Kang Huichi etc. utilize pomegranate always the dry method of falling storage carried out cuttage research, after limb cross cut saw is good, 50 ~ 60 centimetres of dark holes are dug in the shade place, ready limb must be touched the pillow and put hole into, then bury with wet soil, can not loss of moisture lack of water, also too much moisture, after the dormancy in a winter, Second Year cuttage in 5 ~ June.The Stratificated treatment reaching 5 ~ 8 months is carried out in this research, and material easily goes mouldy, and in addition, breeding method of operating is complicated, and growing-seedling period is oversize, time-consuming, and seedling cost is high and cuttage survival rate difficulty is secure.
To sum up, old branch cuttage and seedling culture remain at present view and admire the nursery of potted landscape pomegranate produce in technical barrier, this field still belongs to blank, therefore the method for research and development pomegranate old branch cottage propagation and improve the old branch cuttage survival rate of pomegranate and to have great importance and urgently.
Summary of the invention
For prior art, the object of this invention is to provide the method for a kind of pomegranate old branch cuttage Fast-propagation.Utilize the method can solve the problem of pomegranate old branch cuttage root-taking difficulty, and the method is simple to operate, cost is low, instant effect, achieves pomegranate old branch cuttage Rapid Rooting and breeding.
The method of pomegranate of the present invention old branch cuttage Fast-propagation, step comprises: (1) cuttings is selected and pruned, (2) seedbed is set up and matrix composition, (3) cuttings process, (4) cutting time controls, (5) cuttage and management, (6) transplant;
