High-quality and high-yield fertilization method for tobacco

Tobacco is one of the important economic crops in China. Since tobacco is a favorite crop, the quality of its products is particularly important, but the yield and quality of tobacco are contradictory. When the yield of tobacco is not high, the quality is not high. When the tobacco production reaches a certain level, the yield and quality of flue-cured tobacco rise at the same time until the quality reaches its peak. If production continues to rise, quality will continue to decline. The whole law of tobacco absorption is: less absorption in the early growth stage, the highest absorption in the middle stage, and gradually decrease in the later stage. The peak period of nutrition of tobacco plant absorption towers is mostly 42 days to 58 days after transplanting. This indicates that flue-cured tobacco should be of high quality and nutrients should be provided early.
When the tobacco seedlings can be used, the Shennong brand bio-organic fertilizer and microbial fungi can be used as nutrient soil to cultivate strong seedlings. Before the planting, 10% mature bio-fertilizer can be used, 10% of Shennongong bio-purchasing fertilizer, 30% of rapeseed cake fertilizer, and inorganic Fertilizer 20% is used as a base fertilizer, and the dosage is 50-80 kg. It is also possible to use 50 kg/mu of organic and inorganic compound fertilizer of Shennongong as the base fertilizer. After 35 days to 40 days of tobacco planting, 35-40 kg of potassium nitrate is applied per mu. In order to ensure the peak demand of tobacco seedlings.
