Abstract
The invention belongs to the technical field of plant vegetative propagation, and particularly relates to a method for cultivating seedlings of prunus maritime root suckers. The method is a special new technology for cultivating seedlings of fruits and is suitable for introducing the seedlings of prunus maritime. Themethod for cultivating the seedlings comprises the steps of ditching, root breaking, root sucker seedling management, root division, seedling hardening, transplantation and garden return. According to the method, the survival rate of the cultivated prunus maritime seedlings is high, the seedlings are sprouted and returned to a garden in the same year, labor and time are saved, the period is short, cost is low, the effect is achieved fast, yield results are high, and the method is an advanced prunus maritime seedling cultivating technology.
Description
One, technical field
The invention belongs to technical field of plant asexual propagation, be specifically related to a kind of shore plum root turion seedling-cultivating method.
Two, background technology
Shore plum (Prunus maritima) is the perennial local special fruit tree of the rose family (Rosaceae) Prunus (Prunus), originates in Northeastern United States the Atlantic coast.Shore plum integrates fresh fruit, medicine and ornamental value, and have the multiple resistances such as salt tolerant, drought-enduring, impoverishment tolerant, have quite high productivity and economic worth, applicable large area introduces a fine variety popularization.Domestic successful introduction, but the bottleneck of brood body supply significantly limit its Extend culture in China.Research team headed by Nanjing University makes remarkable progress in cell engineering Seedling is bred, but also there is the problem such as survival rate is not high of high cost, the field planting of plantlet in vitro field.Cuttage is numerous soon another means of shore plum seedling, but common cottage method is not easily taken root, and administrative skill requires very high, and efficiency is low.Introduce a fine variety practice display, shore plum has stronger regeneration from root suckers ability, and the root turion rate of coastal saline soil raw seedling upper 3 year is 2.45 ~ 2.87, and plant division transplanting survival rate is 93 ~ 98%.Therefore the seedling selection mode of propagation in scale beyond doubt a kind of cost effective is carried out by low cost, root turion seedling growing process easy and simple to handle.
Three, summary of the invention
The present invention needs the problem solved to be: overcome the problems such as group training, the high cost in cuttage and seedling culture process, low survival rate, seedling management be complicated, provide a kind of shore plum root turion seedling-cultivating method.
Concrete technical scheme of the present invention is: the present invention is directed to the problems such as the high cost in shore plum group training, cuttage and seedling culture process, low survival rate, seedling management complexity, invented the shore plum root turion seedling-cultivating method of " ditching → be completely cured → root turion seedling management → point root hardening and transplanting Gui Pu ".The difficult problems such as high cost, seedling management is complicated, survival rate is low are solved in the plum root turion seedling raising process of shore, perfect moisture and nutrition (particularly nitrogen, P elements) supply conditions, enhance shore plum root turion shoot root, stem, the growing and rejuvenation of leaf, significantly improve its transplanting survival rate, the cultivation for local special fruit tree shore plum seedling is promoted and is laid a solid foundation.
Compared with prior art, its beneficial effect is in the present invention:
Shore plum root turion nursery reproduction coefficient is high, and survival rate is high, and cost is low and can keep parental trait, saving of work and time.Shore plum is in group training or cutting propagation process, and the normal typical problem occurred is: seedling management is complicated, the high and low survival rate of cost.Use the present invention effectively to solve the problem, significantly improve survival rate, and the strong stress resistance of seedling.Innovation of the present invention mainly contains following points: 2. pre-treating method of being 1. completely cured is completely cured method 3. seedling management method.Use the survival rate of shore of the present invention plum root turion seedling to reach more than 95%, field transplanting survival rate can reach more than 98%, really realizes the advantage of shore plum seedling Clonal regeneration, for the cultivation of its spread provides reliable guarantee.
Four, embodiment
1. ditching: late March-early April, the shore Japanese apricot hat in life in 3 years digs belt ditch around, ditch distance of going in ring elite stand trunk 1.2m, ditch depth 40cm, furrow width 30cm.
2. be completely cured: dig in belt ditch process, cut off plum side, the shore root of diameter 0.5 – 1cm, diameter be greater than the side root of 1cm and main root motionless; With sharp knife, the otch of being completely cured is scabbled, after applying the farm organic fertilizer partly become thoroughly decomposed, with original soil (digging the soil of belt ditch 1.), ditch is filled and led up, water permeable.
3. root turion seedling management: 5-6 month, be completely cured wound and the neighbouring root turion of sprouting successively seedling thereof, carry out thinning as height of seedling 10-20cm, seedling is good in every clump of 2-3 strain of selecting and remain, and all the other are wiped out from base portion; Every 30d, weeding, to loosen the soil 1 time, and spray the prevention and elimination of disease and pests of carbendazim 1000ppm liquid.Also need to water, to keep ground moistening during arid.
4. divide root hardening and transplant Gui Pu: carrying out a point root hardening after root turion seedling growth 30d, divide during root and distribute corresponding root system according to the number of trunk to position, the root new wound libation at an ancient wedding ceremony moves basin hardening after active carbon, point root refining
Miao Shi, Glomus mosseae (the Nicol. & Gerd.) microbial inoculum that inoculation Beijing City Agriculture and Forestry Institute is commercially available, hardening matrix is the peat composed of rotten mosses of 2 parts of volumes and the mellow soil mixture of 1 part of volume, every basin inoculation 20g, the basin footpath of inoculation basin is 13cm, basin height 13cm; Hardening is carried out in greenhouse, and temperature maintains 22 ~ 25 DEG C, and start 3 weeks interior noons with sunshade net shading, after 3 weeks, whole day is shown in light; Spray in every 1 week 1 nutrient solution, in table 1, control the water yield, be as the criterion with blade not dehydration, hardening can transplant Gui Pu after 5 weeks, within before returning garden 1 week, put outdoor for seedling basin.
