为研究烤烟烟株田间生发育,烟叶叶片的开张情况和烟叶外观质量的变化,通过在烤烟生产中增施商品牛粪—有机肥的大田试验。为研究烤烟烟株田间生发育,烟叶叶片的开张情况和烟叶外观质量的变化,通过在烤烟生产中增施商品牛粪—有机肥的大田对比试验,在促进烤烟生长发育、改善烟叶产质量等方面提供参考。 In order to study the field development of flue-cured tobacco plants, the opening of tobacco leaves and the appearance quality of tobacco leaves, a field experiment of applying commercial dung manure-organic fertilizer in flue-cured tobacco production was conducted. In order to study the field growth of flue-cured tobacco plants, the opening of tobacco leaves and the change of appearance quality of tobacco leaves, the comparative experiments on the application of commercial cow dung-organic fertilizer in flue-cured tobacco production can promote the growth and development of flue-cured tobacco and improve the yield and quality of tobacco For reference.
