| Abstract: |
| The variance analytical method is used to study the effect of colour plastic sheet mulching upon soil temperature and soil soisture contents under different soil depths in which tobacco plants are growing in the round plant period and vigor growth in the late stage.Also tobacco root system and chemical composition in tobacco leaves are analysed thereby to provide the base for selecting the colour plastic sheets with fine qualities for the cultivation of tobacco plants with high yields and fine qualities. |
| Key words: soil depth, colour plastic sheet mulching, soil temperature, variance analysis |
