What fertilizer can be applied to tobacco to increase production?
What fertilizer can be applied to tobacco to increase production? Tobacco is a kind of potassium-loving crop. Through the experiment of applying biological potassium fertilizer on tobacco, obvious results have been obtained. When 0.5-1.0 kg biological potash fertilizer is applied per mu, the average yield of flue-cured tobacco per mu is 194.1 kg, which is 13.3% higher than that of the control, and the average middle and upper-grade tobacco is 8.8% higher than that of the control. the yield-increasing effect is similar to that of 15 kg potassium sulfate per mu, but the value-added effect is better than 15 kg potassium sulfate. the cost is only 5% of potassium sulfate. The method of using biological potash fertilizer is simple. First, biological potash fertilizer and organic fertilizer are mixed evenly, combined with tobacco seedling transplanting and planting, and the hole is applied to the base of tobacco seedling. If the seedling is raised in a nutrient bowl, biological potash fertilizer can be mixed into the nutritious soil.
