摘要
为降低烟叶氯离子含量,通过大田施用不同种类吸附剂(硅藻土、活性炭、沸石粉、麦饭石)来探究其对烤烟生长及产质量的影响。结果表明,4种天然吸附剂对烟株早期生长发育有一定的抑制作用,随着吸附养分的释放,天然吸附剂在旺长期和成熟期对烟株生长有促进作用,90 d时硅藻土、沸石粉、麦饭石处理的SPAD值比对照高15.7%~23.7%,活性炭吸附的养分释放缓慢,其对植物生长的促进效果相对较差;施用天然吸附剂对烤后烟叶外观质量影响不大,硅藻土处理得分略低,降低4.7分;施用麦饭石处理的烤后烟叶经济性状相对较好,产值增加210.69元/667 m^(2),但氯离子升高,硅藻土和活性炭处理烟叶氯离子含量下降。
To explores the effects of adding different types of natural adsorbents(diatomaceous earth,activated carbon,zeolite powder,and medical stone)to the soil on the growth,yield,and quality of tobacco for the initial purpose of reducing the chloride ion content in tobacco leaves.The results showed that the four natural adsorbents had a certain inhibitory effect on the early growth and development of tobacco plants.As the adsorbed nutrients were released,the natural adsorbents promote the growth of tobacco plants during the vigorous and mature periods,the SPAD values of diatomaceous earth,zeolite powder,and medical stone treatment were 15.7%to 23.7%higher than the control at 90 days.The nutrient release of activated carbon adsorption was slow,and its promotion effect on plant growth was relatively poor.The application of natural adsorbents had little effect on the appearance quality of roasted tobacco leaves,and the score of diatomaceous earth treatment was slightly lower,reducing 4.7 points.The economic properties of roasted tobacco leaves treated with medical stone were relatively good,with an increase yield of 210.69 yuan/667 m^(2),but the chloride ion content increases,while the chloride ion content decreases when treated with diatomaceous earth and activated carbon.
