| 对甘肃正宁县烤烟垄间和膜上两种不同栽培方式，分别从自然降水的利用率、土壤温湿度的变化、烤烟抗病性、农艺性状及经济效益等方面进行对比分析。结果表明，烤烟垄间栽培比常规膜上栽培自然降水利率增加，使10 mm以下的无效降水变为有效降水，有效保证了烤烟需水关键期的水分需求；0～50 cm土壤湿度提高15%；上中等烟叶比例提高了23.6%；平均增产921 kg/hm-2，增值8 871元/hm-2，效果显著。烤烟垄间膜侧抗旱栽培新技术相比常规膜上栽培技术，除抗旱、抗病、增加土壤水分，提高产量产值外，同时能提早揭膜、培土追肥、减少地膜在土壤中的残留，特别适合在温凉半湿润半干旱气候区进行烤烟垄间膜侧栽培，是烤烟抗旱栽培的一项新措施，推广前景十分广阔。 |
| 英文摘要: |
| Two different cultivation ways for tobacco, between-ridges and on-film, were conducted in the experiment to study their effects on natural precipitation use efficiency, soil temperature and moisture change, tobacco disease-resistance, agronomic characters and economic efficiency. The results indicated that the between-ridge cultivation could increase the tobacco's use of natural precipitation by 16 times compared to the conventional on-film cultivation, and it also enabled the invalid precipitation below 10 mm to become effective, guaranteeing tobacco's demand for water in the critical period. In addition, this cultivation could increase the 0～50 cm soil moisture by 15%, enhance the proportion of medium and top grades of tobacco leaf by 23.6%, increase yield by 921 kg·hm-2, raise the out-put value by 8 871 Yuan/hm-2. In brief, the new cultivation technology of between-ridge and film-side is superior to the conventional on-film way in resisting drought, anti-disease, increasing soil moisture and temperature, enhancing the output value, reducing residual quantity of plastic film in soil, and so on. It is especially suitable for the warm cool semi-moist and semi-arid regions and has a broad prosopect to be extended. |
