Abstract
The effects of different mulching methods on agronomic characters and soil temperature of flue-cured tobacco were studied under field conditions.The results showed that straw mulching and film mulching could significantiy promote growth of flue-cured tobacco in early stage and improve the soil temperature.Compared with straw mulching,plastic film mulching could promote early growth more effective,the case was just the opposite for straw mulching.The effect of straw mulch 500 kg/hm2 treament was beter then 300 kg/hm2 treatment.Various mulching methods showed that the effect of warming on soil temperature decreased in late stage,straw mulching could delay the parietal mature period of 2~3 d,while film mulching could advance it 5 d,moreover,The two mulching methods could significantiy increased the plant height of 35~45 d,also enlarged the tobacco leaf area over the same period,but there was no significant difference was found between straw mulching and film mulching.Moreover,the difference of leaf area between different straw mulching treatment was significant.The findings indicated that the effect of different mulching methods on leaf number was not significant.关键词
