为研究不同有机-无机氮配比对云烟99生长及产质量的影响,通过开展田间试验进行烟株生育期的记录、农艺性状的调查、产量和质量的统计分析等。结果表明,有机-无机氮配比为1∶1时,烤烟大田生育期适中,烟株整体长势较好,成熟落黄及时,烤后外观质量都比较好,产质量较其他处理高。因此,当有机-无机氮配比为1∶1时,有利于烤烟生长发育以及产质量的提高。
In order to study the effects of different organic-inorganic nitrogen ratios on the growth, yield and quality of Yunyan 99, field experiments were carried out to record the growth stages of tobacco plants, the investigation of agronomic traits, and the statistical analysis of yield and quality. The results showed that when the ratio of organic to inorganic nitrogen was 1: 1, the growth period of flue-cured tobacco in the field was moderate, the tobacco plants grew well, the ripe yellow color was timely, and the appearance quality was better after roasting. The quality of the flue-cured tobacco was higher than other treatments. Therefore, when the ratio of organic to inorganic nitrogen is 1: 1, the growth of flue-cured tobacco and the improvement of yield and quality are favorable.
