豫西烟区年降雨量少,时空分布不均,土壤供水与烟叶生产需水出现矛盾,影响该区烟叶产量和质量。研究结果揭示,深耕可有效增加土壤蓄水,冬前起垄比春季起垄提高了土壤的含水量。增加有机肥,不仅增加土壤蓄水力,而且还有效提高烟叶的产量和质量。推迟移栽、地膜覆盖可提高水分利用率。通过以上技术措施,达到旱区烤烟优质稳产的目的 In the west of Henan Province, there is little annual rainfall, uneven distribution of time and space, contradiction between soil water supply and water demand of tobacco production, affecting the yield and quality of tobacco in this area. The results revealed that deep plowing can effectively increase the soil water storage, and the winter furring improves the moisture content of soil compared with the spring furrow. Increase of organic fertilizer, not only increase the soil water retention, but also effectively improve the yield and quality of tobacco. Delayed transplanting, mulching can improve water use efficiency. Through the above technical measures, to achieve high quality and stable production of flue-cured tobacco in arid areas
