Background technology
In September, 2006, the scientific and technical personnel of Kunming tobacco company find a huge variation strain first in the large gold dollar of flue-cured tobacco recommended variety safflower, under local natural growthing condition, surpassing 55d, the individual plant trunk number of sheets its vegetative growth phase surpasses 80, stem girth and reaches about 20cm, transplant and surpass 120d to squaring period, surpass 140d to center flower open season.
The kinds such as the large gold dollar of current our province flue-cured tobacco safflower, K326, cloud and mist 87 are many after the transplanting about 50d grow normal cigarette strain squaring period, and flowering stage is many after the transplanting about 60d.
During 2007～2011 years, by for many years, multi-point shows (seeing Table 1) to the experimental study of red large huge variant: this variant ties up between similar ecological environmental condition succeeding year and all shows basically identical result, squaring period is after the transplanting about 125d the earliest, and flowering stage is after the transplanting about 150d the earliest; But differ greatly between the different location, this may be this variant be converted into from nourishing and growing time of reproductive growth and the ecological conditions such as height above sea level, illumination, heat and transplanting time closely related due to, although show the prematurity characteristic, be not to belong to conventional variety so-called " early blossoming " category yet.Be problems such as solving above-mentioned growth cycle and grow, yield poorly, develop the method for planting that a kind ofly can shorten the seminal propagation cycle, improve seed quality and output and be very important.

Test example 1
1. materials and methods
1.1 test material
2011, (1300 meters of height above sea level) and white car rib (2000 meters of height above sea level) were research object with red large huge variant in residential district, township, Zhushan County, Yiliang County, carry out the technical research in its seminal propagation cycle of shortening.
1.2 test is processed
A: at the white car rib point of 2000 meters of height above sea level, select 50 kind strains not take any Insulation;
B: at the white car rib point of 2000 meters of height above sea level, in selecting 50 kind strains to build heat preservation greenhouse by the end of August;
C: at the white car rib point of 2000 meters of height above sea level, select 50 kind strains to be transplanted to the residential district point of 1300 meters of height above sea level, build simultaneously roof insulating;
D: at the residential district of 1300 meters of height above sea level point, select 50 strains to follow the tracks of accent and examine, do not take any Insulation.
1.3 test method
At the residential district of 1300 meters of height above sea level point, unified red large huge variation strain (hereinafter to be referred as the YK01) strong sprout of growing seedlings.Concentrate 2000 cigarette strains of plantation at two height above sea level points respectively, comparative observation blooming between them, solid situation.
1.4 control measures
Unified seeding row spacing, unified fertilizing amount, unified transplanting time.Other cultivation step carries out with reference to local High Quality Tobacco production management.
2. results and analysis
Found out that by table 2 two height above sea level points are compared, be very beneficial for shortening nourishing and growing the cycle of YK01 at high height above sea level point, but owing to the later stage is affected obviously by low temperature, frost etc., very unfavorable to the sexual propagation of seed.Show that thus transplanting to prosperous long-term temperature may be to affect the budding key factor of flowering habit of YK01.And entering the reproductive growth after date, by creating the environment of a relatively-high temperature or high effective accumulated temperature, it is relatively concentrated just to guarantee to budding, bloom, thereby can obtain the better result that seed maturity is fast, seed production is high.

Remarks: process A owing to affected obviously by winter frost, process strain number that D blooms owing to buddingging seldom, thereby cause the seed production of two processing all very low.
3. conclusion
For the long tobacco of reproductive stage, under stereo-climate of Yunnan province, spend surpassing the 1700m zone at height above sea level its vegetative growth phase, reproductive stage is lower than the 1400m zone at height above sea level spends, and can effectively shorten its seed sexual propagation cycle and increase seed production.
