| Abstract: |
| Through the analysis of meteorological data and the measurement in field experiment,the limiting factors of climate were investigated and the optimal cultivation scheme of tobacco was researched for superior-quality and high-yield.The results showed that the climate in Zhengning County was basically satisfied to the growth of tobacco,but the low temperature and drought during the growth period were the main limiting factors of tobacco production.Moderate early planting was advantageous to improve the yield and quality.The effect of film mulch was remarkable and the optimal cultivation mode was mulching before transplanting. |
