为了提高烟叶的产量和质量,我们在试验、示范的基础上推广了烟草营养钵培育壮苗新技术,不仅促进了烟草栽培技术的进步,而且取得了良好的经济效益。几年来的实践证明,采用营养钵育苗,苗齐苗壮,成苗期较点播切块的侧根条数提高19.2%,单苗干重提高21.5%,移栽无返苗期,成活率达99.8%,大田期长势整齐稳健,收烤后单产提高6.8%,均价提高9.3%,上等烟增加6.2%。
In order to improve the yield and quality of tobacco leaves, we popularized the tobacco seedling cultivation technology based on experiments and demonstrations, which not only promoted the progress of tobacco cultivation technology, but also achieved good economic benefits. Years of practice proved that nutrition bowl nursery, seedling Qi Zhuang Zhuang, seedling stage than on-sowing the number of lateral roots increased by 19.2%, single seedlings increased by 21.5% dry weight, without seedling transplanting survival rate of 99.8 %. During the field, the growing trend was neat and steady. The yield per hectare increased by 6.8%, the average price increased by 9.3% and the fine smoke increased by 6.2%.
