揭膜方式与秸秆覆盖对早植烤烟生长及其产质量的影响

目的]研究揭膜方式及秸秆覆盖方式对早植烟红花大金元烟株生长及产质量的影响.方法]进行了揭膜不覆盖处理（T1）、揭膜全覆盖处理（T2）、揭膜隔行覆盖处理（T3）、不揭膜不覆盖处理（T4）、不揭膜全覆盖（T5）、不揭膜隔行覆盖处理（T6）的随机区组田间试验.结果]不同处理下产量产值T2＞T5＞T3 ＞T6 ＞T1 ＞T4,其中在揭膜处理中T2 ＞T3 ＞T1,且T2与T1之间差异显著,在不揭膜处理中T5 ＞T6 ＞T4,T5与T4之间差异显著,T6与T4之间差异较小.在全覆盖处理中T2＞T5,差异显著,半覆盖处理中T3＞T6,差异显著,不覆盖处理中T1明显大于T4.结论]及时揭膜与适当覆盖稻草有利于提高烟株生长与烟叶品质.

Effects of Plastic Film Mulching and Straw Mulching on the Growth and Yield of Early-plant Tobacco

Objective ] In order to research the effect of film uncovering and straw mulching on tobacco plant growth and yield of Honghuada- jinyuan in early-plant tobacco. Method] A randomized blocks field experiment was carried out, which included 6 treatments. Tl--film un- covering and without mulching, T2 --film uncovering and fully mulching, T3-film uncovering and stagger mulching, T4--witbout film uncov- ering and without mulching, TS--without film uncovering and fully mulching, Tr--without film uncovering and stagger mulching. Result] The results indicated that product with different disposal methods, T2 〉 T5 〉 T3 〉 T6 〉 T1 〉 T4. In the way of film uncovering, T2 〉 T3 〉 T1, and there is remarkable different between T1 and T2. In the way of without film uncovering, T5 〉 T6 〉 T4, and there is remarkable different between T5 and T4, while a similar different between T6 and T4. In the way of fully stripping, T2 〉 T5 and T2 is quite different from TS, by the way, in the way of half film uncovering, T3 〉 T6 and their difference is also notable. In addition, in the way of without mulching, T1 〉 T4. Conclusion] It can be concluded that film Uncovering promptly and mulching appropriately is good for the tobacco＇ s growing and production.
