试验结果表明,在烤烟移栽期低温、生育前期干旱的生态区,浅“V”型垄地膜覆盖模式对提高地温和土壤的含水量作用显著,能增加培土高度,对烟苗早发快长,促进根系的发育创造了良好的条件。为提高烟株的吸收功能,促进烟株正常生长,增强抗性,提高烟叶的产量、质量、效益都具有积极的作用。
The results showed that in the ecological zone where the flue-cured tobacco plants were transplanted at low temperature and drought in the early growing period, the shallow V-shaped ridge film mulching pattern had a significant effect on increasing the soil moisture content of the mild soil, increasing the height of soil for cultivation, , To promote the development of the roots created a good condition. In order to improve the absorption function of tobacco plants, promote the normal growth of tobacco plants, enhance the resistance and improve the yield, quality and benefit of tobacco leaves, they all play a positive role.
