许昌地区的烤烟种子工作,多年来经过群选群育、评定推广,对提高烟叶的产量和品质起到了积极的作用。但是,从农业现代化的要求和轻工、外贸的需要来看,差距还很大,任务还很重。解放初期,许昌地区烤烟品种“多、乱、杂”现象严重。那时,甚至一块烟地往往也有几个品种混杂种植。加上栽培方法落后,直播种植,烤烟要在雨季生长和采收,受黑胫病和雨涝危害十分严重,产低质次,极不保收。一般亩产在120—150斤之间,重灾年尚不足百斤。 Xuchang flue-cured tobacco seeds work over the years through the mass election population, assessment of promotion, to improve the yield and quality of tobacco has played a positive role. However, from the requirements of agricultural modernization and the needs of light industry and foreign trade, the gap is still huge and the tasks are still heavy. In the early period of liberation, the flue-cured tobacco varieties in Xuchang were “more, chaotic and miscellaneous” seriously. At that time, even a piece of tobacco is often mixed with several varieties. Coupled with the backward cultivation methods, direct seeding, flue-cured tobacco growing and harvesting in the rainy season, black shank and floods caused by the very serious harm, low-quality times, very poor. Generally between 120-150 kg per mu, heavy catastrophe less than 100 pounds.
