烤烟是叶用作物,不仅要有一定的产量,更重要的是要有较好的质量。目前国内外优质烟供不应求,而劣质烟则大量压积,且不同质量等级之间的差价很大。因此必须将产量控制在适当的范围,来保证优质烟的生产。我们参考国内外的研究成果和本地的实际情况,确定了保证烤烟优质的适产指标,要求把烟叶亩产控制在300斤左右,上下浮动5%,上等烟10%以上,中等烟65%,黄烟率90%以上,中黄三级原烟烟碱含量大于1.5%,氯钾比小于1。围绕这些指标,我县烤烟工作者探索出一系列相适应的优质适产栽培技术。近几年我们在城郊、樟市、银河等几个乡进行示范栽培取得了极大的成功,上、中等烟由原来的60%提高到75%,产值提高20—50%,内在质量也有较大的提高。我们的栽培措施是: Flue-cured tobacco leaf crops, not only have a certain yield, more importantly, have better quality. At present, domestic and international high quality smoke is in short supply, while low quality smoke is heavily pressured, and the difference between different quality levels is very large. Therefore, we must control the output in the appropriate range to ensure the production of high-quality smoke. We refer to the research results at home and abroad and the local actual situation, to determine the quality of tobacco to ensure that the appropriate indicators of production, requiring control of the tobacco mu yield of about 300 pounds, up and down 5%, more than 10% of fine smoke, 65% , The rate of yellow smoke is above 90%, the content of middle-yellow calf tobacco nicotine is more than 1.5% and the ratio of chlorine to potassium is less than 1. Around these indicators, our county tobacco workers to explore a series of suitable high-quality adaptive cultivation techniques. In recent years, we have achieved great success in demonstrating and cultivating several suburbs in the suburbs, Zhangshi and Milky Way. The upper and middle-level tobacco have been raised from 60% to 75% and the output value has increased by 20-50% Great improvement. Our cultivation measures are:
