Tobacco fertilization techniques

The base fertilizer of tobacco generally applies all the farmyard manure, phosphorus and potassium fertilizers and about 60% of the nitrogen fertilizer. Top dressing: About 40% of the nitrogen fertilizer is used for topdressing, and topdressing can be carried out twice. For flue-cured tobacco, sun-cured tobacco and burley tobacco, it should not be later than 30 days after planting; and the topdressing of sun-cured tobacco and cigar can be late. Tobacco fertilization is commonly used for acupoint application, ditching, and watering. The depth of fertilization should be within 5-20 cm of soil. Simultaneous application of ammonium nitrogen and nitrate nitrogen in tobacco is effective: nitrogen deficiency is not easy in the early stage, and nitrogen is excessive in the later stage. It is in line with the fertilizer requirement law of “small and rich, old and poor”, which is conducive to the normal yellowing of tobacco, easy to bake, and good flammability. Tobacco is very sensitive to chlorine. When the leaves contain more than 1% chlorine, the leaves will burn poorly, and in severe cases, the flame will be extinguished. Therefore, it is necessary to use less fertilizer with more chlorine and compound fertilizer using it as raw material. The calcium absorbed by tobacco is second only to potassium, and it is also prone to zinc deficiency. It is necessary to timely supplement the deficiency of calcium and zinc in the soil.
