Description
Technical Field
The invention relates to a method for optimizing nitrogen metabolism of tobacco plants to control green turning of green tobacco leaves in a mature period, and belongs to the technical field of tobacco planting.
Background
The green-returning tobacco is the phenomenon that tobacco leaves which have reached maturity or are close to maturity in the field obviously turn green and tender after experiencing overcast and rainy little sunshine for a long time, and lose the original mature characteristics. The reason for the green-turning of tobacco leaves is mainly related to the nitrogen reabsorption of tobacco plants. In general, the absorption and utilization of nitrogen by tobacco plants reach a peak value before and after budding, then the absorption and utilization are obviously reduced, and tobacco leaves are gradually matured. Due to uneven distribution of factors such as drought, precipitation, illumination and the like during the growth period of flue-cured tobacco, great difference exists in the supply and utilization of fertilizers in soil. In the harvesting and baking season, if the residual nitrogen in the soil is more, and the moisture and the temperature of the soil are favorable for the growth of tobacco leaves in continuous rainy days, the green turning phenomenon of the tobacco leaves is easy to occur, and is represented by the height of tobacco plants, the thickness of the tobacco leaves, dark green leaf color, green and late maturity, difficult yellowing and the like. After the tobacco leaves are turned green, the tobacco leaves are difficult to enter a normal mature state in a short time, and at the moment, if green ribs and ash-hanging cigarettes are easily baked during green robbing, picking and baking, the quality of the tobacco leaves is adversely affected, and the normal seeding of next-stubble crops can be delayed due to the extension of the growth period.
The nitrogen plays an important role in the quality formation and style characteristics of the flue-cured tobacco, and the nutritional status of the nitrogen plays an important role in the nitrogen metabolism, growth and development, yield and quality of the flue-cured tobacco and the availability of the flue-cured tobacco. Nitrogen is a main component for synthesizing chlorophyll and the like, is a basis for alkali nitrogen metabolism, and has an important effect on synthesizing sufficient plastid pigment and improving the photosynthetic efficiency due to sufficient nitrogen supply in the early growth and development stage of tobacco plants. The green-returning tobacco is turned green and tender in the mature period, so that the tobacco leaves are not mature enough and are difficult to bake. Therefore, the invention provides a method for accelerating the metabolic transformation of nitrogen and promoting the layered yellowing of tobacco leaves in the field.
Disclosure of Invention

(3) Spraying KH with the mass percentage concentration of 2-3% on the leaf surfaces of the III-class striking-green tobacco leaves2PO4Or K2SO4And 50-80 mg/L ethephon mixed solution for 2-4 times, and spraying once every 3-5 days.
The SPAD value of the type I striking root tobacco leaves is 30-35.
The SPAD value of the type II green-turned tobacco leaves is 36-40.
The SPAD value of the III-class striking-off tobacco leaves is 40-50.
The invention has the beneficial effects that:
the method of the invention sprays ethephon and KH2PO4(K2SO4) The ethephon promotes the leaf maturation, and the potassium dihydrogen phosphate composite leaf surface potash fertilizer is sprayed to accelerate the nitrogen metabolism conversion and promote the layered yellowing of the tobacco leaves in the field. The method judges the green-turning degree of the green cigarette through the SPAD value, and is more targeted and better in effect.
