【摘要】 以云烟87为试验材料,研究叶面肥烟白金和锌铜大师在烤烟上的应用效果。结果表明:与常规肥相比,烟白金对生育期、农艺性状、化学品质影响不大,但能增加中上等烟叶比例和产值,中上等烟比例增加6.82个百分点,产值增加6 709.05元/hm~2;锌铜大师对烤烟农艺性状有一定影响,增加了产量,但产值较低,不建议使用。更多还原

【Abstract】 Using Yunyan 87 as experimental material,the effects of foliar fertilizers Yanbaijin and Xintongdashi in fluecured tobacco were studied. The results showed that, compared with conventional fertilizer, Yanbaijin had little effect on growth period, agronomic characters and chemical quality, but it could increased the proportion and output value of medium and highgrade tobacco leaves. The proportion of medium and high-grade tobacco leaves increased by 6.82 percentage points and the output value increased by 6 709.05 yuan/hm~2. Xintongdashi had a certain impact on the agronomic characters of flue-cured tobacco and increase the yield, but the output value was low, so it is not recommended to use.更多还原
