对自选烤烟新品系HQ一号在衡阳地区的移栽期、移栽密度、留叶数和施肥量等主要栽培技术进行了研究。结果表明,在3月5~15日移栽和120 cm×(50~60)cm的移栽株行距,烟株农艺性状和烟叶经济性状虽有一定差异,但未达显著水平。株高有随留叶数和施肥量增加而增高的趋势;烟叶产量和产值呈现出随施肥量增加而提高的变化规律,均以施纯氮195 kg/hm2的处理最高,与施135 kg/hm2处理间存在显著差异;留叶数对烟株农艺性状和烟叶经济性状的影响较小。综合试验结果,HQ一号在衡阳地区栽培,于3月10~15日移栽,种植密度为15 000~16 500株/hm2,留叶数22~24片/株,施纯氮量为150~1 785 kg/hm2,能够发挥HQ一号的特性,生产出优质烟叶。
The main cultivation techniques of transplanting period, transplanting density, leaf number and fertilizer amount of HQ No. 1, a new self - selected flue - cured tobacco variety, were studied in Hengyang area. The results showed that although the transplanting spacing and the row spacing of 120 cm × (50 ~ 60 cm) between March 5 and March 15 were different, the agronomic traits of tobacco plants and the economic traits of tobacco leaves were not significantly different. The plant height showed a trend of increasing with the number of leaves remaining and the amount of fertilizers increased. The yield and value of tobacco leaf showed the increasing trend with the increase of fertilizer amount, and the highest was with 195 kg / hm2 nitrogen application, hm2 treatment there are significant differences; leaf number on the tobacco plant agronomic traits and economic performance of tobacco leaves smaller. According to the comprehensive test results, HQ No.1 was cultivated in Hengyang area and was transplanted from March 10 to March 15 with a planting density of 15 000 to 16 500 plants / hm 2, leaf number of 22 to 24 leaves / plant, and nitrogen content of 150 ~ 1 785 kg / hm2, able to exert the characteristics of HQ No. 1 to produce high quality tobacco leaves.
