The invention discloses a method for the total amount control of a tobacco potassium fertilizer and the topdressing application after transplantation. The method comprises the following steps: 1) a base fertilizer is applied, the fertilizer application period is the time of tobacco seedling transplantation, and the fertilizer application amount is 45-55% of the potassium fertilizer application amount; 2) a first topdressing is performed, the fertilizer application period is 15-25 days after tobacco seedling transplantation, and the topdressing amount is 15-25% of the potassium fertilizer application amount; 3) a second topdressing is performed, the fertilizer application period is 35-40 days after tobacco seedling transplantation, and the topdressing amount is 15-25% of the potassium fertilizer application amount; and 4) a third topdressing is performed, the fertilizer application period is 60-65 days after tobacco seedling transplantation, and the topdressing amount is 5-15% of the potassium fertilizer application amount. According to the method, the potassium fertilizer can be accurately applied, the demands for potassium fertilizers in different growth periods of tobacco plantsare satisfied, the problem of blind potassium fertilizer application by tobacco farmers can be effectively solved, at the same time, the yield of tobacco leaves are increased, the quality of tobacco leaves are improved, potassium fertilizers are saved, economic benefits of tobacco leaf planting and the utilization rate of potassium fertilizers are improved.
Description
technical field [0001] The disclosure generally relates to agricultural production technology, and specifically relates to a method for controlling the total amount of potassium fertilizer in tobacco and moving fertilization after topdressing. Background technique [0002] Tobacco is an important economic crop, which plays a very important role in local fiscal revenue. Tobacco planting is also one of the effective ways for farmers in poor areas to get rid of poverty and become rich. Reasonable nutrient management is the first factor that determines the yield and value of tobacco leaves, and its contribution rate reaches 39% and 47% respectively, and its contribution to tobacco leaf quality is second only to the variety, reaching 25%. Nutrient management is the core technology to regulate the yield and quality of tobacco leaves. Tobacco is a typical potassium-loving crop. Sufficient potassium supply can not only ensure the normal physiological metabolism and robust growth of...
