摘要
为了确定文山州贫氯地区氯肥的适宜施用量,对烟田进行了施用氯肥的试验,纯氯用量分别为0、22.5、45.0、67.5、90.0 kg/hm2。结果表明,在本试验范围内,施氯并不会明显影响烟株生育期;以施纯氯67.5 kg/hm2处理的烟叶含氯量最接近0.3%~0.8%,且烟叶产量增幅最大,外观质量最好,油分足;同时,随着施氯量的增加,烟叶还原糖含量提高,烟碱和蛋白质含量降低,化学成分趋于协调,K/Cl比更合理。从经济、安全施氯考虑,文山州烟田施氯量以45.0~67.5 kg/hm2为宜。
In order to determine the suitable amounts of chlorine in chlorine-deficiency areas of Wenshan, the field experiment on application of chlorine fertilizers was conducted.The chloride was applied at 0,22.5,45.0,67.5,90.0 kg/hm2 respectively.The results showed that using chlorine fertilizers obviously not influenced growing period of flue-cued tobacco so much,the treatments of 67.5 kg/hm2 showed the best results,the tobacco leaves contains amount of chlorine increased gradually ,near to 0.3%-0.8% ,the tobacco yield was the highest ,the leaf had the best appearance and was rich in oil.And then,when the quantities of chlorine fertilizers was increased, the reductive sugar of the tobacco leaves contented exaltation, the protein and the content lower nicotine ,the chemistry composition tended in the coordination, and the ratio of potassium to chlorine was more harmonious. Considered from the economy and safe factors, the proper amounts of chlorine fertilizers in Wenshan Area was 45.0~67.5 kg/hm2.
