Problems solved by technology

During the planting and growth process of flue-cured tobacco in the field, it is very susceptible to factors such as bacteria, viruses, or natural climate, which will cause various viral diseases or natural climate spots on the leaves, roots, or stems, directly affecting the normal growth of flue-cured tobacco and the quality of tobacco leaves after curing. Edible value, reducing the quality of tobacco leaves will not only cause damage to the income of tobacco farmers, but also have non-negligible harm to human health
At present, when dealing with various diseases caused by flue-cured tobacco, pesticides are often used to reduce flue-cured tobacco pests and diseases. To a certain extent, it can reduce the disease infection rate of flue-cured tobacco and reduce the loss of tobacco farmers. However, the spraying of pesticides directly causes the toxic components to be absorbed by the leaves and processed Absorbed by the human body when it is made into cigarettes, or pose a serious health threat to the human body
At the same time, Yunnan, Guizhou and other main flue-cured tobacco production areas often cause major natural disasters due to the low rainfall during the important growth period of flue-cured tobacco and the failure of tobacco farmers to irrigate the dry flue-cured tobacco in time, causing great losses to the economic benefits of tobacco farmers

Embodiment 1

[0017] The flue-cured tobacco K326 variety is selected. At the level of about 200kg per mu, the basic agronomic characteristics of the flue-cured tobacco plow layer are 0.73% organic matter, 0.217% total nitrogen, available phosphorus 6.3*10-6, available potassium 54*10-6, slow-acting potassium It is 447*10-6, pH6.9. The maximum water holding capacity of the soil field is 24.6%. A fertilization method to reduce the infection rate of tobacco leaf wildfire disease and tobacco mosaic disease and improve the drought resistance of flue-cured tobacco. The amount of nutrients absorbed by flue-cured tobacco is different during the growth process: the total content of pure potassium applied per mu during the entire growth period is 25kg, pure The total content of nitrogen is 7.5kg, and the total content of pure phosphorus is 2.5kg. First, as a base fertilizer, 7.5kg of pure nitrogen, 2.5kg of phosphorus fertilizer, and 19kg of potassium fertilizer were applied when the flue-cured tobac...

Embodiment 2

[0019] The flue-cured tobacco Yunyan 85 variety is selected. At the level of about 180kg per mu, the basic agronomic characteristics of the flue-cured tobacco plow layer are 0.64% organic matter, 0.24% total nitrogen, available phosphorus 5.7*10-6, available potassium 51*10-6, slow-acting Potassium is 426*10-6, pH6.6. The maximum water holding capacity of the soil field is 23.8%. A fertilization method to reduce the infection rate of tobacco leaf wildfire disease and tobacco mosaic disease and improve the drought resistance of flue-cured tobacco. The amount of nutrients absorbed by flue-cured tobacco is different during the growth process: the total content of pure potassium applied per mu during the entire growth period is 35kg, pure The total content of nitrogen is 8.0kg, and the total content of pure phosphorus is 3.0kg. Firstly, as a base fertilizer, 8.0kg of pure nitrogen, 3.0kg of phosphorus fertilizer and 29kg of potassium fertilizer were applied when the flue-cured tob...

Embodiment 3

[0021] The flue-cured tobacco Yunyan 87 variety is selected. At the level of about 180kg per mu, the basic agronomic characteristics of the flue-cured tobacco plow layer are 0.67% organic matter, 0.29% total nitrogen, available phosphorus 6.6*10-6, available potassium 65*10-6, slow-acting Potassium is 493*10-6, pH6.4. The maximum water holding capacity of the soil field is 27.2%. A fertilization method for reducing the infection rate of tobacco leaf wildfire disease and tobacco mosaic disease and improving the drought resistance of flue-cured tobacco is characterized in that the amount of nutrients absorbed by flue-cured tobacco is different during the growth process: the total content of pure potassium applied per mu during the entire growth period is 30kg, the total content of pure nitrogen is 7.6kg, and the total content of pure phosphorus is 2.6kg. Firstly, as a base fertilizer, 7.6kg of pure nitrogen, 2.6kg of phosphorus fertilizer and 24kg of potassium fertilizer were ap...

Abstract

The invention relates to a fertilizing method for lowering the infection rates of wildfire disease and mosaic disease of tobacco leaves and improving drought resistance of flue-cured tobacco. The method comprises the steps of applying 25-35 kg of pure potassium, 7.5-8.0 kg of pure nitrogen and 2.5-3.0 kg of pure phosphorus to each mu of land; in the transplanting process, applying 7.5 kg of pure nitrogen, 2.5 kg of a phosphatic fertilizer and 27.5 kg of a potash fertilizer in a furrow-application mode; when flue-cured tobacco grows to the about 30 day, dressing a potash fertilizer, wherein the pure potassium content is 6 kg, and conducting ridging at the same time; applying a base fertilizer in a furrow-application mode, wherein the depth is 20-25 cm below the soil layer, the combined application ratio of a citrate-soluble potash fertilizer to a potash fertilizer special for tobacco is 3: 1, the combined application ratio of woody peat to carbonized flue-cured tobacco straw is 9: 1, and the woody peat content of the dressed potash fertilizer is 9%. According to the flue-cured tobacco planted through the fertilizing method, the infection rates of wildfire disease and mosaic disease are lowered by 50% and 23% respectively, the drought situation under the drought condition is mitigated to a certain extent, and great practicability is achieved.

Description

technical field [0001] The invention relates to a fertilizer application method for crops, in particular to a fertilization method for reducing the infection rate of tobacco leaf wildfire disease and tobacco mosaic disease and improving the drought resistance of flue-cured tobacco. Background technique [0002] As a hobby economic crop, flue-cured tobacco has the highest value among the whole tobacco plants. During the planting and growth process of flue-cured tobacco in the field, it is extremely susceptible to factors such as bacteria, viruses, or natural climate, causing various viral diseases or natural climate spots on the leaves, roots, or stems, directly affecting the normal growth of flue-cured tobacco and the quality of tobacco leaves after curing. Lowering the edible value and reducing the quality of tobacco leaves will not only cause damage to the income of tobacco farmers, but also cause non-negligible harm to human health. At present, when dealing with various ...
