稻草覆盖栽培改变了烤烟生长的田间微环境,通过对稻草覆盖栽培条件下烤烟不同施肥模式的比较和研究,发现稻草覆盖下的集中施肥模式有如下优点:能够促进烤烟株高增高,茎围增粗;叶面积增加,叶数增多;生长稳健,耐熟性提高;增产提质显著,还能减轻烟农的劳动强度,是一种较好的平衡施肥操作模式。 Straw-covered cultivation changed the micro-environment in the field of flue-cured tobacco growth. By comparing and researching different fertilization modes of flue-cured tobacco under straw-covered cultivation conditions, it was found that the concentrated fertilization mode under the straw covered has the following advantages: Thick; leaf area increased, the number of leaves increased; steady growth, maturity increased; yield significant improvement, but also reduce the labor intensity of farmers, is a better balance of fertilization mode of operation.
