黔西南煙葉品質分區(qū)研究
Regional Planning of Tobacco Leaf Quality in Southwestern Guizhou
-
摘要: 為了進行更合理的煙葉生產布局,，對黔西南州煙葉品質進行了多年的監(jiān)測，并對煙葉品質進行了區(qū)劃,。初步提出用總糖和煙堿2個因子作為品質分區(qū)指標,，共分為3個檔次，①高：總糖含量＞26%,，煙堿含量＞2.5%,；②中：總糖含量24%～26%，煙堿含量2.3%～2.5%,；③低：總糖含量＜24%,，煙堿含量≤2.3%。根據(jù)分區(qū)指標,，黔西南煙葉可分為3個類型區(qū)：高糖低堿區(qū),，高糖中堿區(qū),，中糖中堿區(qū),。黔西南煙葉以高糖中堿區(qū)為主，占80%,，高糖低堿區(qū)占20%,，中糖中堿區(qū)過去曾經(jīng)種過煙，目前尚待開發(fā),。Abstract: To achieve better planning of tobacco production in southwestern Guizhou, authors monitored the tobacco leaf quality for several years, and conducted leaf quality regional planning. The authors proposed total sugar and nicotine contents of leaves as partition index for regional planning, and classified them as three levels: high ( total sugar content > 26%, nicotine content > 2.5%), middle (total sugar content 24%～26%, nicotine content 2.3%～2.5%) and low (total sugar content <24%, nicotine content ≤2.3%). According to these criteria, the tobacco leaf quality of southwestern Guizhou could be classified as three zones: the zone with high sugar and low nicotine contents, the zone with high sugar and middle nicotine contents, and the zone with middle sugar and middle nicotine contents. The first zone covers 80% of tobacco production area in southwestern Guizhou, the second zone covers 20%, and the last zone had tobacco production years ago and needs to be developed for tobacco production.
