一、培育杈烟是一项有效的增产措施培育杈烟,在我省已有悠久历史。樅阳、宿松等晒烟区很早就有在主茎烟收后培育杈烟的办法,因为杈烟在秋后收获晒制,称为秋烟。解放后,杈烟在烤烟生产中也广泛应用起来。培育杈烟通常有四种类型:第一,主茎烟生长不正常,如遭受旱涝灾害发生早花时,留杈烟可作为补救的生产措施。如1954年我省烤烟遭受严重涝灾,在此情况下,培育了六万多亩杈烟,一般亩产三十斤,凤阳双山农业社亩产还达到一百三十二斤;1955年因春烟受旱而培育杈烟三万多亩,一般亩产也在四十五斤左右。第二,主茎烟生长良好的,培育杈烟,更能爭取丰收。1960年获得烤烟大面积丰收的定远八一公社靠山大队和怀远曹老集公社新馬桥大队一半丰产 First, to cultivate the twig smoke is an effective stimulation measures to cultivate the twig smoke, which has a long history in our province. Zongyang, Susong and other areas have long been in the main tobacco stem flue-cured tobacco stems after cultivating twigs, because the twigs in the autumn after harvest sun, known as autumn smoke. After the liberation, the twig tobacco is also widely used in the production of flue-cured tobacco. There are usually four types of cultivating twigs: First, the growth of the main stem is abnormal. If the droughts and floods occur as early as possible, the remaining twigs can be used as remedial measures. In 1954, for example, flue-cured tobacco in our province suffered serious floods. Under such circumstances, more than 60,000 mu of banyan were cultivated and thirty pounds were generally mu per mu. The per-mu yield of Fengyang Shuangshan Agricultural Society also reached 132 kilograms. In 1955 Because of spring drought and cultivate more than thirty thousand acres of twigs, the general mu is about forty-five pounds. Second, the main stem tobacco grows well, cultivating twigs and cigarettes, and better for harvest. In 1960, a large area harvest of flue-cured tobacco Dingyuan Bayi commune brigade and Huaiyuan Cao Lao commune Xinmaqiao Brigade half of the high yield
