Description
Technical field
The present invention relates to nursery stock breeding technical fields, and in particular to a kind of locust tree crossbreeding technology.
Background technique
Locust tree (Robinia pseudoacacia), is subordinate to locust tree section.Locust tree wood belongs to hard wood, and material is heavy and hard
Firmly, wear resistant and impact resistant, compressive resistance is strong, resistance to water-wet with it is rotten, be that house bridge, building, ore pillar, the manufacture of mechanical car and boat, processing are each
The excellent of kind tool etc. uses material.Fast-growing, high yield, high-quality, resistance locust tree kind are selected, is the pass for developing locust tree fast-growing andhigh-yeilding trees
Key.
Locust tree has the characteristics that ecological diversity, genetic diversity, especially their extensive adaptability, i.e., to bad ring
The resistance in border is very prominent, utilization ways are more.Breeding locust tree new varieties, and afforested using choiceness, it can effective land productivity
With hybrid vigour, forestation of locust benefit is significantly improved.Currently, in order to improve the quality of locust tree, insider's general choice hybridization
Breeding technique.But current hybridizing method have the defects that it is certain, can be lower with rate, and can not significantly improve the product of locust tree
Matter.
Summary of the invention
The object of the present invention is to provide a kind of locust tree crossbreeding technologies, and the breeding method is reasonable, can be high with rate, Neng Gouti
Height significantly improves the quality of locust tree.
In order to solve the problems existing in background technology, the present invention adopts the following technical scheme:
1, the parental apolegamy of cross combination: according to fast-growing, straight, high-quality, drought resisting, cold-tolerance breeding Breeding objectives are done, selection has phase
Like the parent of character；
2, pollen collection: acquisition time is 5~April of April 12 (locust tree comes into bloom), and brosse is entered vierics with writing brush
In ware, in order to guarantee pollen activity, discoloration osmanthus glue is added into the pollen of collection and keeps drying, and the cryo-conservation in -20 DEG C,
It is spare；
3, maternal processing: before anther dehiscence for 24 hours, carrying out emasculation operation to each inflorescence little Hua, cover hybridization bag, spare；
4, it pollinates: when ovule column cap is shinny, when secreting transparent mucus, unlocking hybridization bag, with the pollen by acquisition that writing brush is careful
It awards above ovule column cap.Rear enclosure hybridization bag is completed in pollination, releases hybridization bag after a week in pollination；
5, fruit development management: the petal sector-meeting for completion of being fertilized gradually falls off, and column cap is gradually withered, and ovary increases rapidly, if awarding
2~3d still fresh column cap answers hand-pollinated after powder, prevents fruit drop, and fruit development period should keep room temperature 18~27
DEG C, interior will divulge information, it should be noted that change water, pay attention to preventing pest and disease damage, if there is shedding phenomenon, need to extract some infructescence, promote fruit
Real growth and development；
6, the harvest of hybrid seed: when fruit maturation, taking fruit pod, strips out seed, stores spare.
Cross breeding method of the present invention is reasonable, can be high with rate, can be improved the quality of locust tree.
Specific embodiment
Present embodiment uses following technical scheme:
Locust tree cross breeding method are as follows:
1, the parental apolegamy of cross combination: according to fast-growing, straight, high-quality, drought resisting, cold-tolerance breeding Breeding objectives are done, selection has phase
Like the parent of character；
2, pollen collection: acquisition time is 5~April of April 6 (locust tree comes into bloom), and brosse is entered vierics with writing brush
In ware, in order to guarantee pollen activity, discoloration osmanthus glue is added into the pollen of collection and keeps drying, and the cryo-conservation in -20 DEG C,
It is spare；
3, maternal processing: before anther dehiscence for 24 hours, carrying out emasculation operation to each inflorescence little Hua, cover hybridization bag, spare；
4, it pollinates: when ovule column cap is shinny, when secreting transparent mucus, unlocking hybridization bag, with the pollen by acquisition that writing brush is careful
It awards above ovule column cap.Rear enclosure hybridization bag is completed in pollination, releases hybridization bag after a week in pollination；
5, fruit development management: the petal sector-meeting for completion of being fertilized gradually falls off, and column cap is gradually withered, and ovary increases rapidly, if awarding
2~3d still fresh column cap answers hand-pollinated after powder, prevents fruit drop, and fruit development period should keep room temperature 18~27
DEG C, interior will divulge information, it should be noted that change water, pay attention to preventing pest and disease damage, if there is shedding phenomenon, need to extract some infructescence, promote fruit
Real growth and development；
6, the harvest of hybrid seed: when fruit maturation, taking fruit pod, strips out seed, stores spare.
Cross breeding method of the present invention is reasonable, can be high with rate, can utmostly realize locust tree directional trend breeding, significantly mention
The quality of high locust tree.
Embodiment described above only describe the preferred embodiments of the invention, and but it is not limited to this, this
The technical staff in field is easy to understand spirit of the invention according to above-described embodiment, and makes different amplification and variation, but
As long as it does not depart from the spirit of the invention, all within protection scope of the present invention.
