Abstract
The invention belongs to STEVIA REBAUDIANA breeding technique, a kind of STEVIA REBAUDIANA autumn adds the method for crossbreeding.Prior art autumn, next year carried out STEVIA REBAUDIANA crossbreeding work, the disadvantage is that Breeding progress is slow, efficiency is low, of high cost according to current year STEVIA REBAUDIANA field trial as a result, formulating Hybridizing plan.The method of the present invention harvests the seed of reciprocal cross respectively after moving into Protectorate cultivation, seed maturity when second half year current year taking the cuttage of STEVIA REBAUDIANA stem, transplant planting, fertilising, parent's isolation cultivation, insect pollination, autumn air temperature low.The method have the advantages that:Accelerate Breeding progress, improves breeding efficiency;Save breeding cost.
Description
Technical field
The invention belongs to STEVIA REBAUDIANA breeding techniques, and in particular to a kind of STEVIA REBAUDIANA autumn adds the method for crossbreeding.
Background technology
The STEVIA REBAUDIANA blade 6-12% of glycosides containing synanthrin, fine work are white powder, and sugariness is 250--450 times of sucrose, calorific value
It is the 1/300 of sucrose, is a kind of natural sweetener of sugariness low in calories, high.It is not absorbed, is not generated after synanthrin glycosides intake human body
Heat is diabetes and the sweetener that bariatric patients are applicable in, is the important source material of food and pharmaceutical industries, is widely used in sugar
In fruit, cake, beverage, solid beverage, fried pot foods, seasoning, preserved fruit.Glycosides Contents height is quickly bred in STEVIA REBAUDIANA industry
Kind, for increase stevioside total output, improve STEVIA REBAUDIANA cultivation economic benefit, promote human health suffer from
Important role.STEVIA REBAUDIANA different lines intermolecular hybrid is the important technical for cultivating STEVIA REBAUDIANA new varieties.Breeder is every
Year will formulate Hybridizing plan, carry out crossbreeding work according to breeding objective and existing each strain in upper performance in 1 year.
The prior art is annual spring sowing autumn harvest, can only carry out generation STEVIA REBAUDIANA crossbreeding within 1 year.The shortcomings that conventional method is breeding work
It is low to make efficiency, it is slow to cultivate new varieties progress.
The present invention provides a kind of STEVIA REBAUDIANA autumns to add the method for crossbreeding, accelerates STEVIA REBAUDIANA crossbreeding progress,
Improve breeding work efficiency.
Invention content
The purpose of the present invention is to provide a kind of quickening crossbreeding progresses, improve the STEVIA REBAUDIANA autumn of breeding work efficiency
Add the method for crossbreeding.
The invention is realized in this way:
A kind of STEVIA REBAUDIANA autumn adds the method for crossbreeding, includes the following steps:
(1) cutting time:Early July;
(2) transplant planting:The STEVIA REBAUDIANA seedling of cutting survival is colonized among flowerpot;
(3) organic fertilizer is imposed:After cuttage seeding survives, decomposed soya-bean cake fertilizer 20-30g is applied per basin;
(4) chemical fertilizer is imposed:Alternately urea and potassium dihydrogen phosphate 2g/ basins were imposed per 5-7 days;
(5) isolation cultivation:Before blooming, each parents of STEVIA REBAUDIANA for being ready for hybridization are subjected to 500m with other STEVIA REBAUDIANA materials
Above space isolation, continues to cultivate;At the florescence, the pollination that parents are carried out by insect hybridizes;
(6) Protectorate cultivation:Early October, weather turn cool, and STEVIA REBAUDIANA, which is connected basin, to be moved into vinyl house, and protecting field is carried out
Heat preservation cultivation, ensures seed maturity;
(7) seed of reciprocal cross is harvested after seed maturity respectively.
The present invention's is technically characterized in that:
The various Other Main Agronomic Characters in the first tenday period of a month in July, the STEVIA REBAUDIANA of spring cultivation display substantially, by observing, compare and
Analysis, can formulate follow-on Hybridizing plan on this basis.The cultivation crossing work of STEVIA REBAUDIANA is arranged in by the prior art
The spring of next year, next year autumn harvest to hybrid seed.The present invention changes into the Hybridizing plan in spring next year ought be during the lunar New Year
Half a year carries out, and can harvest the seed of hybridization for the year, so that breeding process is advanced by 1 year quality time, accelerate breeding
Progress improves breeding efficiency.STEVIA REBAUDIANA is intercepted on the STEVIA REBAUDIANA plant that second half year cultivation hybridization can also directly be grown in the field
Stem section be used for cuttage, vinyl house nursery will be occupied in winter by eliminating spring cultivation, and will take off daily, cover keep the temperature cover
The tedious work of cover material, improves work efficiency.
It is an advantage of the invention that:
1. accelerating Breeding progress, breeding efficiency is improved.
2. saving breeding cost.
Specific implementation mode:
Below by specific implementation mode, the present invention will be further described.
A kind of autumn adds the method for crossbreeding, includes the following steps:
Anhui takes the STEVIA REBAUDIANA plants stems cuttage planted current year along Huaihe River basin, STEVIA REBAUDIANA plantation, spring sowing, early July;By skewer
It is inserted into STEVIA REBAUDIANA seedling living to be colonized among flowerpot, 2kg soil is packed into basin;After cuttage seeding survives, decomposed beans are applied per basin
Cake fertilizer 20-30g;Impose chemical fertilizer:Alternately urea and potassium dihydrogen phosphate 2g/ basins were imposed per 5-7 days;Before blooming, will prepare into
The space that each parents of STEVIA REBAUDIANA of row hybridization carry out 500m or more with other STEVIA REBAUDIANA materials is isolated, and continues to cultivate;At the florescence, by
Insect carries out the pollination hybridization of parents;Early October, weather turn cool, and STEVIA REBAUDIANA, which is connected basin, to be moved into vinyl house, is carried out
Protecting field heat preservation cultivation, ensures seed maturity;The seed of reciprocal cross is harvested after seed maturity respectively.
Above-described embodiment is only preferred examples of the present invention, and is not intended to limit the present invention, all within the principle of the present invention,
Any modifications and variations done, within protection scope of the present invention.
Claims (1)
