(一)引种鉴定 种植烤烟,首先要选择好适合于本地区栽培的优良品种。如何选择引进一个优良品种,要考虑以下几个因素。 1、适于本地区的气候条件。烤烟对气候条件的要求主要有温度、雨量、日照,其中温度条件最为重要。①温度。烟草是一种喜温作物,在整个生长发育过程中,要求有比较高的温度。生长最适温度25～28℃,最低温度10～12℃,最高35℃。种植烤烟要求海拔必须在1300米以下地区,年平均气温大于9℃,大于10℃,积温3000℃以
(A) the introduction of Identification of flue-cured tobacco planting, we must first select good varieties suitable for cultivation in the region. How to choose to introduce a good variety, to consider the following factors. 1, suitable for the climatic conditions in this area. Flue gas requirements of climate conditions are mainly temperature, rainfall, sunshine, of which the most important temperature conditions. ① temperature. Tobacco is a kind of hi-temperature crop, in the whole growth and development process, requires a relatively high temperature. Growth optimum temperature 25 ~ 28 ℃, the lowest temperature of 10 ~ 12 ℃, the highest 35 ℃. Flue-cured tobacco planting requirements must be below 1300 meters above sea level, the annual average temperature is greater than 9 ℃, greater than 10 ℃, temperature 3000 ℃ to
