| 中文摘要: |
| 通过气候资料分析和田间试验观测,找出正宁烤烟栽植的气候制约因素,寻求优质高产烤烟栽植应对方案。结果表明,正宁烤烟大田生长期气候基本可以满足优质烤烟的生长,但低温干旱是优质烤烟生产的主要制约因素。适时早栽,有利于提高产量和品质。覆膜栽植效益明显,最佳覆膜方式为栽前覆膜。大畦三铺底双膜育苗,可提高畦内温度,提早育苗3~5 d,增加有效育苗数。改进式双层配方施肥,保肥保水,分阶段供肥,增产效益好。 |
| 英文摘要: |
| 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. |
