Abstract

The invention provides a Cercis chinensis propagation method, which includes steps of land preparation, seedbed making, management of cuttings, seedling management and the like. According to the characteristics of large-scale seedling propagation in large nurseries, seedbed specifications, cutting specifications, cutting storage methods and cuttage management methods are reasonably selected for cuttage propagation of Cercis chinensis. By the Cercis chinensis propagation method, cuttage survival rate of Cercis chinensis reaches 98%, Cercis chinensis can flower on April in the next year, and the requirement of fast growth into useful timber is met.

Description

The cuttage and seedling culture method of a kind of cercis

Technical field

The present invention relates to the ornamental plant seedling-cultivating method, be specifically related to the cuttage and seedling culture method of a kind of cercis.

Background technology

Cercis ( Cercischinensis), the Caesalpiniaceae redbud.Arbor, trunk is obvious, Gao Keda 8-10 rice, diameter of a cross-section of a tree trunk 1.3 meters above the ground 50cm mostly is the shrub shape under the cultivation situation.Be distributed in provinces such as Hubei, Liaoning, Hebei, Shaanxi, Gansu, Guangdong, Yunnan, Sichuan, happiness light, certain cold resistance arranged, fertile, well-drained soil is liked in the leeward place on the sunny side of need planting in Beijing, anti-flooding not, and sprout tillers is strong, anti-pruning.

Cercis leaf subcircular, long 6-14cm, the anxious point of end of blade, the phyllopodium heart, full edge, the two sides does not have hair, and on 4-10 Yu Laozhi that clusters of flower aubergine, the long 5-14cm of pod has narrow wing along linea ventralis, and is open before the leaf April at florescence, fruit maturation in October.Germinating power is strong, multi-branched, anti-pruning, tree-like open, branch hangs low, the petal obovate, rose-red or purple rugose rose (Rosa rugosa var is red, the florescence is long, suitable group planting reaches lawn edge before garden, building, because the Shi Yeshang of blooming does not send, so should plant to prospect with evergreen pine and cypress or plant in light object front, by white-washed wall or rock.

Cercis is shaky usually, mainly adopts methods such as cuttage, bud grafting to carry out vegetative propagation.Therefore providing the cottage method that a kind of technology is perfect, survival rate is high is the problem that this area is badly in need of.

Summary of the invention

The invention provides the prolific cercis cottage method in a kind of adaptation nursery, by putting in order ground, doing steps such as bed, plugged ear processing, seedling management, can provide environmental condition preferably for the cercis cottage propagation, improve cuttage survival rate.

The present invention is made up of following steps:

(1) wholely: nursery lot selects that quality is loose, well-drained sandy loam or loam, and plough deeply 20-30cm the autumn of cuttage the previous year, effectively eliminates soil insect and germ, strengthens the ability of retaining and conserveing soil moisture simultaneously; Rake the soil level spring in next year, and degree of depth 20cm applies well-rotted farmyard manure 100 in conjunction with the per hectare of raking the soil level, 000kg, and diammonium phosphate 200kg, potassium sulphate 300kg carries out soil disinfection simultaneously, adopts 800 times of carbendazim that soil is sprayed comprehensively.

(2) make bed: the wide 105cm of bed surface, height of bed 15cm, length is decided according to physical features, bed spacing 35cm, bed surface is smooth, bed surface is watered permeable, hug with flat rake flat, covering with plastic film raising low temperature, cuttage behind the 5d;

(3) plugged ear clip and processing: behind cuttage cercis in autumn the previous year stops growing, leaf the falls light, from the cercis elite stand clip give birth to then, grow enrich, the branch of no damage by disease and insect, cutting length 12-15cm, upper cut is cut into flat mouthful, apart from roof pressure 2cm, following clip is cut sth. askew into the shape of a hoof, apart from end bud 1cm, the alignment of per 20 stem cutting fringe bottoms is tied; Soak with clear water and to put into Sha Zangkeng behind the 2h of back and survive the winter, husky Zang Keng to build in leeward on the sunny side, the higher place of physical features, avoid ponding.Cheat dark, wide 2m, length is decided as required.The thick common brick of the end, hole shop 30cm, the wet river sand that upper berth 30cm is thick; The centre swings in the plugged ear of tying up, shop 10cm sand between every layer of plugged ear, and the surface, hole covers compacting all around with straw screen or mat;

(4) go up the taking-up plugged ear April, after in flowing water, soaking 24h, the lower cut immersion is held in the container of 250kg/kg heteroauxin and 800 times of carbendazim mixed liquors, soak 10min, take out, open the mulch film on the bed surface, on ready-made seedbed, insertion depth is the 1/2-1/3 of branch with plugged ear straight cutting or oblique cutting, and seeding row spacing is 20*20cm, water permeablely after inserting, note preserving moisture;

(5) in earlier stage (after the cuttage in 20 days) seedling bed temperature is controlled at 20-25 ℃, and the latter temperature humidity requirement is not tight; Every 2d carries out bed surface and page sterilization with tpn after the cuttage, and carries out foliage spray in per 10 days, adopts 2g/kg potassium dihydrogen phosphate and 1g/kg urea mixed solution liquid level to spray when topdressing; Weeding in time, loosen the soil, the process of weeding with a hoe is avoided loosening and the injury cuttage seeding, stops the control measures that all promote seedling growths after mid-July, and humidity increases phosphorus potash fertilizer consumption, promotes the nursery stock lignification.

Beneficial effect:

The present invention is directed to the characteristics of large-scale nursery large-scale breeding nursery stock, for the cottage propagation of cercis has reasonably been selected seedbed specification, plugged ear specification, plugged ear preservation mode and cuttage management method.After adopting the inventive method, the cercis cuttage survival rate can be bloomed up in April, 98%, second, and pattern is gorgeous.Reach the requirement of becoming a useful person rapidly.

Embodiment

Embodiment 1:

The present invention relies on the following step to implement:

Note surviving the winter winter protection behind the fall foliage, next year can use.
