Abstract
The invention discloses a softwood cuttage propagation method for Acrocarpus fraxinifolius according to the principle of vegetative propagation. Fine clone seedlings can be propagated in quantity by the softwood cuttage propagation technique for Acrocarpus fraxinifolius, and accordingly high yield and high quality of colonies can be realized. The softwood cuttage propagation method for Acrocarpus fraxinifolius is characterized in that rooting agent GGR-6 is provided by Beijing ABT research and development center, the rooting agent GGR-6 is made into 800-1000mg/L solution at constant volume, talcum powder is added into a container in multiple phases during mixing until the solution is pasty, the lower ends of semi-lignified shoots 10-15cm long are dipped into the paste and inserted into a nonwoven nutrition bag having 5cm diameter and nutrition substance composed of pine bark and sawdust in a ratio of 3:1, water-fertilizer management and disease damage control are performed as required after cuttage, and the shoots grow and survive in two months.
Description
Technical field
The present invention relates to a kind of top fruit tree softwood cutting propagation method, belong to the plant asexual multiplication technology field.
Background technology
The top fruit tree is the high megaphanerophyte of Caesalpiniaceae, is precious commerical tree species of one's native land, is again good tor reproducting tree species, and existing natural resources are rare, classified as China three-level protective plant.Produce at present to go up and mainly adopt seed to carry out seeding and seedling raising, phenotype differs seedling because the diversity of genetic material is grown after afforestation, is difficult to reach the purpose of colony's high yield and high quality.Plant asexual multiplication technology has been widely used in the forest cuttage and seedling culture, adopts top fruit tree softwood cutting propagation technology can breed a large amount of choiceness nursery stocks, thereby can reach the purpose of colony's high yield and high quality.
Summary of the invention
The present invention utilizes the vegetative propagation technique of plant cuttage; Clip top fruit tree epicormic branch cuttage carries out asexual propagation; The choiceness nursery stock that can cultivate neat high yield is used for producing afforestation, for the needs that satisfy fruit tree seedling market, top provide a very effective approach.
For solving the problems of the technologies described above, technical scheme of the present invention is following:
(1) in mid-March～mid-April, fruit tree is grown directly from seeds and chooses that give birth to half a year the nursery stock or the healthy and strong nursery stock of annual advantage cuts and does short cultivation of sprouting from the top, and cutting dried highly is 25～30cm, adopts the fringe elite stand as what spray was provided;
(2) in the first tenday period of a month～late August in May, from adopting the long semi-lignified spray of clip 10～15cm on the fringe elite stand, top keeps 5～6 leaflets, and every leaflet keeps 1/2 area, and the branch lower end cut is the angle shape;
(3) insert sticking the getting of fringe lower end 2～3cm and add the pastel that talcum powder mixes by rooting powder solution;
(4) cuttage time elder generation water squirts nutrient matrix, on the seedbed, inserts an aperture with small wooden again, will insert fringe then and insert in the nutrient matrix, and insertion depth is 4～5cm, will insert fringe matrix compacting on every side at last, and cutting density is advisable with the blade non-overlapping copies;
(5) branch after the cuttage being used obscurity is that 70% black sunshade net shades, and adopts intermittent spray-on process to carry out spraying and moisturizing to inserting fringe.In first week after the cuttage, be 10～15 minutes daytimes the blanking time of spraying water, and at 20～30 minutes nights, each water spraying time is 15～20 seconds.After one week of cuttage, water spray is adjusted into 20～30 minutes daytimes blanking time, and water spraying time is 30～60 seconds, stops spray evening.Keep after 2 months, remove the sunshade net.Every at a distance from 1 800～1000 times of 50% carbendazim solution of 7～10 days foliage-sprays, whenever at a distance from one time 0.2% urea of pouring in 10～15 days and 0.2%KH
2PO
4Solution.
2, top according to claim 1 fruit tree softwood cutting propagation method; It is characterized in that the root-inducing powder in the step (3) is the GGR-6 that Beijing Ai Bidi (ABT) research and development centre produces; The concentration of the root-inducing powder aqueous solution is 800～1000mg/L; Compound method is: root-inducing powder is soluble in water with cosolvent, and constant volume is mixed with 800～1000mg/L solution then, adds talcum powder in the container several times at last and stirring simultaneously; Until the furnishing pasty state, viscosity with insert the fringe lower end sticking get not drip behind this pastel get final product.
3, top according to claim 1 fruit tree softwood cutting propagation method; It is characterized in that the nutrient matrix composition in the step (4) is a pine bark: after sawdust=mixture fully fermented in 3: 1; Use diameter to form as the non-woven bag can of 5cm; Be cut into 10～12cm section before the cuttage and put in the plastics screen frame of long 50cm * wide 50cm * dark 10cm, irrigate, get final product cuttage after 24 hours with 0.5% liquor potassic permanganate.
Beneficial effect: top provided by the invention fruit tree softwood cutting propagation method; Its practicality simple to operate is applicable to extensive cuttage, and seedling raise period is short; After the cuttage 60 days; Seedling percent is up to more than 80%, and seedling can effectively keep the good genetic character of elite stand, guaranteed the unanimity of new plant with the elite stand fine quality.
