| 摘 要： | 以烤烟NC89为材料,研究抗旱综合栽培措施和常规栽培措施2种方法对烟草生长发育的影响.结果表明,综合栽培措施具有保水、保墒,促进烟株早发的作用;同时,采用综合栽培措施的处理有将水分富集于20cm土层的能力,烟株长势强,根系发达,叶面积指数大,叶倾角小,消光系数小,能充分利用光能,提高光合效率,改善烟叶质量,提高上等烟比例.

| Abstract: | The experiment in the effect of comprehensive and common measures on the growth of flue-cured tobacco variety-C.V NC89 was conducted.The results showed that the comprehensive measure preserved the soil moisture and accelerated the earlier growth,in the meantime,it also had the capacity of gathering water into the surface soil lay of 20?cm in depth so that tobacco growth was promoted,the root flourished,leaf area index became large and coefficient extinction of light was little,which caused the plant to take the great use of solar energy and promote the efficiency of photosynthesis,improved the quality of tobacco leaf and raise the ratio of the first class or middle leaf. |
