Abstract
The present invention relates to a kind of by Light media Chinese bandoline wood Light media nutritious bag cuttage and seedling culture height planting percent breeding method.The technical scheme adopted is: in May ~ September will fill the nutritious bag of Light media, put into thimerosal soak 6 ~ 10h after flood go out, for cuttage after covering 2 days with sealed by film.Before cuttage, Light media nutritious bag after sterilization is put into breeding cave dish successively, and the cave dish filling Light media nutritious bag is placed on seedbed.From the raw then semi-lignified spray that Chinese bandoline wood elite plant gathers, be cut into cuttings, and put into complex liquid immersion, after 1h, pulled out the 0.5h that dries in the air.Be inserted into sterile-processed after Light media nutritious bag in, build arc canopy, with membrane sealed, and keep 70% light transmittance, in film, relative moisture remains on more than 80%, and regular carbendazim carries out disinfection and sterilizing.Carry out Chinese bandoline wood Light media nutritious bag cuttage seeding according to the method to cultivate, its cuttage planting percent can reach more than 95%.
Description
Technical field
The present invention relates to the asexual Cultivating techniques field of a kind of Chinese bandoline wood nursery stock, is a kind of Light media nutritious bag cuttage and seedling culture height planting percent breeding method specifically.
Technical background
Chinese bandoline wood (Machiluspauhoi) is fast, aesthetic in appearance, the broad-spectrum excellent evergreen broad-leaved indigenous tree species of a kind of growth.In recent years, along with domestic and international to the continuous increase of this Tree Species Resources demand, a large amount of natural Chinese bandoline wood forest is felled, many areas only retain a small amount of seeding-growth, market resource problem in short supply all the more shows especially, resource price is in ascendant trend year by year, and existing market sale price is 3000 ~ 3600 yuan/kg(fresh weight), cause the serious concern of relevant departments.Therefore, large area artificial breeding is badly in need of, to solve the shortage problem of this seeds nursery stock resource.At present, these seeds mainly adopt seed seedling-raising technology to carry out seedling-wood breeding.But because Chinese bandoline wood exists low, the solid shakiness of ripening rate, seed without resting stage, be difficult to storage, and conventional skewer technology of inserting is difficult to the features such as cutting survival, cuttage planting percent are low.Therefore, the asexual cultivation of Chinese bandoline wood nursery stock high planting percent approaches to cultivation question is the excellent nursery stock of current effective cultivation Chinese bandoline wood, and large area cultivates the important key issue being badly in need of in Chinese bandoline wood high grade producing woods solving.
Summary of the invention
For solving low, the solid shakiness of Chinese bandoline wood ripening rate, seed without resting stage, be difficult to storage, large area afforestation nursery stock shortage of resources and be difficult to stable provide the problems such as excellent nursery stock, the invention provides a kind of Chinese bandoline wood Light media nutritious bag cuttage and seedling culture height planting percent breeding method.
The technical scheme adopted for achieving the above object is:
1. the disinfecting of Light media nutritious bag and cuttage seedbed: soaked by the potassium permanganate disinfection solution that the Light media nutritious bag being used for cuttage puts into 0.1% concentration, after 7 ~ 9h, flood goes out and for cuttage after covering 2 days with sealed by film.Before cuttage, the Light media nutritious bag after sterilization is put into breeding cave dish successively, and the cave dish installing Light media nutritious bag is placed on seedbed, water with running water and wash Light media, allow the thimerosal in Light media naturally flow out, utilize the thimerosal flowed out to carry out disinfection to seedbed.Cuttage is got final product when Light media nutritious bag waters to wash to have no till red liquid flows out.
2. the sterilization of cuttings and root induction method: choose robust growth, without the raw then semi-lignified spring tip of damage by disease and insect or the spray of autumn growth May to September from excellent Chinese bandoline wood plant, be cut into the cuttings that 3 ~ 5cm is long, every root cuttings retains 2 leaves, 1 axillary-bud or top-bud.The cuttings of intercepting is soaked in complex liquid, pulls out after 1h and be placed on shady and cool ventilation and dry in the air after 0.5h and carry out cuttage.
3. cuttage: cuttings inserted in the Light media nutritious bag after sterilization, the cuttage degree of depth is 2-3cm.Cutting seeding row spacing is about 5cm × 10cm, compresses matrix immediately, to make cutting bottom and matrix close contact after inserting.Water permeable after inserting, and build arc canopy in the above in time, with membrane sealed, shelter from heat or light and keep 70% light transmittance, can not open in slotting latter 15 days.
4. water and fertilizer management after inserting: cuttage, after 15 days, need be watered once every two weeks, made relative moisture in film remain on more than 80%; Separately carried out disinfection and sterilizing with carbendazim 1000 times of liquid every 10 days; To more than 90% rooting of cuttings (by random sampling estimation) two weeks afterwards, film can be removed; Carry out foliage spray by every 15 days potassium dihydrogen phosphates by 600 times of liquid concentration or A Kang composite fertilizer, solution usage is every 100m
2need 30kg.
Described complex liquid mixes by 1:1:1 weight ratio with methyl α-naphthyl acetate with agricultural streptomycin, carbendazim, state's photoproduction, and then dilute 500 times.
