Description

The selection that a kind of flue-cured tobacco is high-quality slender joss stick and nitrogen efficiently utilizes
Technical field
The choosing that high-quality slender joss stick and nitrogen efficiently utilizes the invention belongs to Tobacco Genetic Breeding technical field more particularly to a kind of flue-cured tobacco Educate method.
Background technology
Tabacco fragrance is an important factor for weighing its quality and availability.Compared with international advanced production cigarette country, at present I Outstanding problem existing for state's quality of tobacco is that aroma quality is poor, perfume quantity is insufficient.It improves tabacco fragrance, improve tobacco leaf flavor and taste, at For the main direction of China's tobacco leaf production.Kind is to improve the basis of tobacco production and value, is the most important factor for influencing tobacco aroma. Therefore, the high fragrance new flue-cured tobacco varieties of selection and breeding, to meeting the raw materials requirement of Chinese-style cigarette brand, ensureing the sustainable development of sound tobacco Exhibition has great importance, and also has become emphasis and the task of top priority of China's tobacco breeding work.
Nitrogen is to influence tobacco growing development, yield and the most important nutrient of quality, China tobacco planting area position It is at the forefront in the world, but utilization rate of nitrogen fertilizer is less than world average level, and the loss of farmland nitrogenous fertilizer can not only reduce agricultural economy effect Benefit can also cause soil acidification, hardened, water body polluted by nitrogen, restrict agricultural sustainable development.General nitrogen is efficiently existed using crop Still with the ability for keeping normal growth, biological yield and normally for being approached under the conditions of nitrogen when nitrogen nutrient concentration is low.It is logical It crosses the good nitrogen of breeding high-yield and efficiently utilizes tobacco bred, fully excavate the gene potentiality of crop itself, be to improve nitrogen profit With a kind of effective way of efficiency.
102657076 A of Patent document number CN, disclosing one kind having high fragrance, and miscellaneous gas is light, tobacco hybridization in good taste Producing method for seed, by being female parent with kind horse ear cigarette of suncuring tabacco, flue-cured tobacco cultivars Bi Na 1 carries out artificial hybridization for male parent, collects miscellaneous Kind F1 is new lines Y28.Y28 has the characteristics that high fragrance.But since suncured tabacco kind horse ear cigarette modulation system is in the invention Drying, causes its offspring Y28 to be not easy to toast, and low output, tobacco grower's economic benefit is relatively low.
105340449 A of Patent document number CN disclose a kind of fertilizing method improving nitrogen of flue-cured tobacco utilization rate, pass through Site preparation basal dressing, is applied and carries seed manure, apply foliar fertilizer, spraying fertilizer, apply the fertilizing methods such as balance fertilizer to improve flue-cured tobacco nitrogen the transplanting of band liquid manure Plain utilization rate.The invention mainly improves nitrogen utilization efficiency by fertilizing method, does not excavate the gene potentiality of crop itself fully, Fail inherently to improve the utilization ratio of tobacco nitrogen.
Invention content
The technical problem to be solved by the present invention is to:The selection that a kind of flue-cured tobacco is high-quality slender joss stick and nitrogen efficiently utilizes is provided, with The target strain that high-quality slender joss stick and nitrogen efficiently utilizes rapidly and accurately is selected from filial generation, to solve existing flue-cured tobacco cultivars fragrance The problems such as matter, perfume quantity are insufficient, and fertilizer utilization efficiency is not high.
The technical scheme is that:The selection that a kind of flue-cured tobacco is high-quality slender joss stick and nitrogen efficiently utilizes, includes the following steps:
(1) it is female parent with high-quality high-quality slender joss stick flue-cured tobacco cultivars, using the flue-cured tobacco efficiently utilized to nitrogen as male parent, hybridizes to obtain F1 generation kind Son;
(2) winter current year carries out south numerous added-generation, and selfing obtains F2 for seed;
(3) F2 segregating generations are planted in low fertility plot in selecting, wherein amount of nitrogen is less than the production of local sound tobacco Normal usage, phosphate fertilizer and potash fertilizer are administered by local sound tobacco production normal usage;
(4) it harvests Flue-cured and carries out single plant and smoke panel test, compared, sieved with the same preferable flue-cured tobacco cultivars of position aroma quality It selects judging parameter aroma quality and perfume quantity is better than or is equivalent to the single plant of control flue-cured tobacco cultivars, plant division bagging axillary bud is reserved seed for planting;
(5) strain is planted:The single plant of (4) screening is planted by step (3) and is selected at group, then by step (4);
(6) step (5) is repeated until strain is stablized, you can screens high-quality slender joss stick and flue-cured tobacco new lines that nitrogen efficiently utilizes.
In the step (4), 170~190 centimetres of plant height is selected in field, natural leave the piece number 25~28, Pinch 110~120 centimetres of plant height, can picking leaves the piece number 20~22, middle part maximum leaf grow 65~90 centimetres, wide 25~35 centimetres Single plant is listed, and when full blossom normally pinches, and stays a larger axillary bud to reserve seed for planting convenient for bagging, remaining axillary bud is normally removed, in middle leaf When ripe, adopt 9~13 leaf positions and carry out the listed baking of single plant, carrying out single plant to baking rear blade smokes panel test.
It is compared with flue-cured tobacco cultivars K326.
The total nitrogen content of soil in low fertility plot is between 0.6~2g/kg in described, and the content of organic matter is in 10~30g/ Between kg.
In abovementioned steps (3), amount of nitrogen is less than the 30% of the production normal usage of local sound tobacco.
The beneficial effects of the invention are as follows:The present invention, can using strains screening techniques such as F2 segregating populations, backcrossing selection groups With the flue-cured tobacco new lines for rapidly and accurately selecting high-quality slender joss stick and nitrogen efficiently to utilize from filial generation, to solve existing flue-cured tobacco product The problems such as kind aroma quality, perfume quantity are insufficient, and fertilizer utilization efficiency is not high.The flue-cured tobacco cultivars of selection and breeding of the present invention have it is high-quality slender joss stick, easily roasting, The features such as suitable production.It is tested through applicant, using obtained flue-cured tobacco new lines of the invention when saving nitrogen fertilizer amount 30% or so, Fragrance is slightly better than current main breed K326, hence it is evident that is better than main breed cloud and mist 87.
Specific implementation mode
Invention is described further with reference to specific embodiment:
High-quality high-quality slender joss stick explanation in the present invention:It is generally acknowledged that aroma quality, perfume quantity are more than or are equivalent in smokeing panel test in industry K326 is compareed, high-quality slender joss stick kind is regarded as.
N in Tobacco efficiently utilizes explanation:It is generally acknowledged that nitrogen high-efficiency crop still has when nitrogen nutrient concentration is low in industry Keep normal growth ability, biological yield with normally under the conditions of nitrogen approach, that is, be considered the flue-cured tobacco efficiently utilized to nitrogen Kind.
