Description

A kind of method of mapler leaf clematis introduction and acclimatization breeding

Technical field

The invention belongs to biological technical field, be specifically related to the method for the introduction and acclimatization breeding of a kind of ornamental flower mapler leaf clematis.

Background technology

Clematis ( clematisL.) belong to Ranunculaceae (Ranunculaceae), be the plant that rare large flower and brilliant color in liane, flower pattern are changeable, the florescence is abundant, its horticultural use is extensive, enjoys the good reputation of " liana queen ".According to the characteristic of different cultivars, the application modes such as potted flower, wall greening, corridor, front yard beautify can be had, and achieved fabulous effect in states such as Europe, the dark favor being subject to fan and gardens circle personage.Whole world Actions of Clematis Species about more than 300 is planted, and China has 147 kinds, and all there is distribution various places, especially distributes in the majority with Central China and southwest, and distribution is extremely wide, resource type various (Zhang Yan etc., 2010; Huang Fang etc., 2010) be, that Actions of Clematis Species distributes one of maximum area in the world.

Mapler leaf clematis ( clematisacerifoliaMaxim.) be Actions of Clematis Species, be China's peculiar species resources, the dark favor by numerous clematis fan.Its plant build is short and small, high 30-60cm, is upright undershrub, and old branch crust grey, has ring-type slight crack.Leaf is single leaf, its April at florescence, and leaf and flowers are raw, pentagon, calyx sheet 5-8 sheet to June May phase for fruit, white or be with pink, spends beautiful greatly.It is distributed in the endangered and endemic plant near Beijing on the cliff of low mountain; because its distributed areas are narrow, population quantity is few, and this Plants has been listed in Beijing first class of protection plant; also being the ornamental plants very treasured early spring, is the important wild ornamental plant in Beijing area.Mapler leaf clematis requires strict to habitat, have the good name of " rock flower ", it is difficult to introduce a fine variety and cultivate the difficult problem having become insider and generally acknowledged.Mapler leaf clematis is tamed in success both can protect these wildlife species, in addition, we was carried out to the vertical greening work tools such as vertical planting, Hanging virescence, wall greening and was of great significance.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, a kind of method that mapler leaf clematis introduction and acclimatization is bred is provided.The mapler leaf clematis being suitable for growing on basic rock is realized potted plantization cultivation, both can protect this endangered species, and the flowers of this beauty of mapler leaf clematis can be allowed again to become potted flower and carry out merchandized handling, come in Hua Youjia.

technical scheme:

1. substrate composition and sterilization: the matrix of sowing selects pure river sand; The matrix of cuttage selects pure river sand: stone=1:1 or pure river sand, irrigates matrix before cuttage and sowing with 50% carbendazol wettable powder, 800 times of liquid;

2. sow: select healthy full mapler leaf clematis seed, it be sprinkling upon uniformly and fill up in the flowerpot of river sand, the river sand that surface coverage one deck 3-5mm is thick afterwards, irrigates with clear water; Every 3-7 days waters a clear water, is under the condition of 15-25 DEG C in environmental temperature, and 15-20 days visible seedling cotyledons can carry out the follow-up daily cultivation management of (step 5) for 30 days;

3. cuttage: the mapler leaf clematis brachyplast of gathering is cut to the long cuttings of 2-4cm, every cuttings retains 2-3 bud point and 1 blade, and the IBA solution that cuttings base portion puts into 2000mg/L dips in 60s, then inserts in flowerpot by cuttings, the degree of depth is 1/2 ~ 2/3 of cutting length, 10, each flowerpot;

4. cuttage manages: after cuttage, first time waters permeable, and later auto spraying feedwater, keeps humidity 10% ~ 15%, waters matrix every 7 ~ 10 days with 50% carbendazol wettable powder, 800 times of liquid simultaneously.Within after cuttage 120 days, enter and can enter daily cultivation management (step 5);

5. daily cultivation management: by seedling and cuttage seed containing pure river sand: in the flowerpot of stone=1:1 or pure river sand, water with nutrient solution, pouring in every 3-7 days once.

the present invention has following characteristics:

1. the success of introduction and acclimatization mapler leaf clematis, for mapler leaf clematis opens road at the artificial planting in Jiangsu.Make the mapler leaf clematis no longer just rock flower of growth on the crag of Beijing area, a large amount of artificial planting mapler leaf clematis can be passed through, both can protect this endemic species, and can also be produced by potted plantization, make mapler leaf clematis become potted flower and come in the family of flowers fan;

2., by this method cuttage mapler leaf clematis, rooting rate can be made to reach more than 85%;

3., by this method sowing mapler leaf clematis, percentage of seedgermination can be made to reach 95%;

4., by this method maintenance cultivation mapler leaf clematis, the growth that mapler leaf clematis is good in flowerpot can be made; Survival rate is to 95%, and growth rate is significantly better than the contrasts such as clear water.

embodiment:

(1)the collection of seed and branch:

Gather mapler leaf clematis seed and branch respectively in May, 2013 and Beijing in May, 2014 city Miaofeng Shan Mountain, preserve branch with antistaling box, preserve seed with seed packet, be transported to Nanjing;

(2) sow:

By mapler leaf clematis planting seed in the basin alms bowl containing pure river sand, then cover the thick river sand of 3-5mm above, irrigate with clear water.Within every 3-7 days, water once with clear water, be under the condition of 15-25 DEG C in environmental temperature, after planting about 15-20 days visible cotyledons, entered daily cultivation management according to step 5 after 30 days;

(3) cuttage

Cuttage: mapler leaf clematis branch is made the cuttings that 2-4cm is long, each cuttings contains 2-3 bud point, and stays a slice blade; Fill up river sand by flowerpot: the matrix of stone=1:1 or river sand, before cuttage, irrigate matrix with 50% carbendazol wettable powder, 800 times of liquid.The IBA solution that cuttings base portion puts into 2000mg/L dips in 60s, then inserts in flowerpot by cuttings, and the degree of depth is 1/2 ~ 2/3 of cutting length, and 10 short fringes inserted by every basin;

Hide sun-proof with 85% shade net after cuttage is complete, 9:00-17:00 auto spraying feedwater every day, once, a 7-12s, cloudy day every 50min spray once, once sprays 10s to the every 10min spray of fine day.Spray with the turbid liquid of 50% carbendazol wettable powder 800 times weekly and irrigate.Cuttage entered daily cultivation management according to step 5 after 120 days.

Table 1: matrix type is on the impact of mapler leaf clematis cuttage

This research has selected 5 kinds of substrate combination to carry out cuttage research, research finds wherein river sand: the cutting plantation of stone=1:1 and river sand all can reach 86.2% and 85%, and selects peat: perlite=1:1, quartz sand, quartz sand: the cutting plantation of stone=1:1 matrix is 0;

(4) management after surviving

Mapler leaf clematis is the rock flower of growth in rock crevice, and habitat unique like this causes its special growing environment.P in soil H value near mapler leaf clematis habitat is 7.2, and the rainwater of Nanjing and the equal slant acidity of running water (pH value is 6.2).The mapler leaf clematis poor growth that research discovery is watered with clear water, leaf turns yellow gradually; The growth of alone nutrient solution pouring is slower; The combination that selection buck+nutrient solution (PH7.2) waters, the growth of seedling entirety is fast, and does not occur yellow leaf phenomenon.Adopt sodium hydroxide that the pH value of the nutrient solution prepared is adjusted to 7.2 for this reason.Water with nutrient solution, pouring in every 3-7 days once.
