烤烟生产者要想烤烟获得优质适产,必须严格按照规范化生产,才能提高烤烟内在质量,取得较好的经济效益。可是,目前大部分地区仍然采用传统方法移栽,拔苗时只带少量的老娘土,有的根本就不带老娘土,烤烟移栽后根系受到损伤,返苗期较长(一般需要7天左右),生长缓慢,因弱苗死亡引起的查苗补栽,又使整个烟田参差不齐,给管理工作造成许多困难。致使生长期长,成熟期晚,推迟了采烤时间,影响烤烟内在质量和经济效益的提高。河南省宝丰县从1984年开始,对烤烟栽培技术进行改革,摸索出“切块干起育苗移栽”方法。经过几年来的实践,证明切块干起育苗移栽不伤根,返苗快,成活率高,大田生长快,发育好,病虫害明显减少,成熟 Flue-cured tobacco producers want flue-cured tobacco to obtain good quality, must be strictly in accordance with the standardization of production, in order to improve the inherent quality of flue-cured tobacco, and achieve better economic returns. However, most areas are still using traditional methods of transplanting, pulling only a small amount of the mother when the soil with the mother, and some do not take the mother, the roots after transplanting flue-cured tobacco, seedling back longer (usually takes 7 days ), Slow growth, seedlings caused by the death of weak seedlings replanting, but also make the entire tobacco fields uneven, causing many difficulties in management. Resulting in a long growing season, late maturity, postponed the mining time, affecting the inherent quality of tobacco and economic benefits. Baofeng County, Henan Province since 1984, the cultivation of tobacco cultivation techniques to explore and explore the “cut from the nursery transplanting” approach. After several years of practice, proved that the cuttings from the transplanting seedlings do not hurt the root, fast seedling back, high survival rate, field growth, development, pests and diseases significantly reduced, mature
