Embodiment 1
[0012] First weigh the compound fertilizer (N:P 2 o 5 :K 2 O=10:10:20), potassium sulfate (containing K 2 O 50%), potassium nitrate (containing N 13%, K 2 O 45%) and other conventional fertilizers (these fertilizers are available in the market), these fertilizers are fully mixed with nano-carbon powder according to the mass ratio of 1000:1 to carry out nano-synergistic treatment, and then the synergized fertilizer is granulated, The nano synergistic compound fertilizer, the nano synergistic potassium sulfate and the nano synergistic potassium nitrate are respectively made into particles with a particle size of 1-5 mm.
[0013] The nano-synergy compound fertilizer and the nano-synergy potassium sulfate were applied at one time as the base fertilizer at the time of ridging, and the nano-synergy potassium nitrate was applied as the topdressing at 20 days after transplanting.
[0014] The test of improving the potassium content of tobacco leaves by the present invention was ca...
Embodiment 2
[0019] Repeat Example 1, with the following differences: the mass ratio of each fertilizer to nano-carbon powder is 1000:3.
[0020] The test results of application example 2 show that, compared with conventional fertilizers, under the condition that the amount of fertilizer remains unchanged, the potassium content of tobacco leaves increases by 40.75%, 21.41% and 25.26% respectively in the cluster stage, vigorous stage and mature stage. See Table 2 below

Embodiment 3
[0024] Repeat embodiment 1, have following difference: each fertilizer and nano carbon powder mass ratio are 1000:5.
[0025] The test results of application example 3 show that, compared with conventional fertilizers, under the condition that the amount of fertilizer remains unchanged, the potassium content of tobacco leaves increases by 22.95%, 28.75% and 36.84% respectively at the cluster stage, vigorous stage and mature stage. See Table 3 below

Abstract
The invention discloses a nanometer synergistic method for improving potassium content of tobacco leaf, which comprises the step of preparing synergistic increasing fertilizers: mixing commonly used fertilizers for cured-tobaccos comprising compound fertilizers, potassium sulfate and nitrate fertilizers respectively and uniformly with nanometer carbon powder according to a proportion of 1,000 to 1-5 to implement nanometer synergistic treatment and then pelleting the fertilizers, and respectively preparing the fertilizers into granular nanometer synergistic compound fertilizers, nanometer synergistic potassium sulfate and nanometer synergistic nitrate with a grain diameter of 1-5mm. The detail applying method is as follows: the fertilizers are respectively applied before field ridging and after cured tobacco transplanting. The nanometer synergistic method for improving potassium content of tobacco leaf has the advantages as follows: as nanometer carbon is nanometer grain with small size and high surface energy activity and can form a polymer with nutrient ions like nitrogen, phosphorus and potassium in liquid, the fertilizer utilization rate is improved, and the fertilizer loss is reduced. Experimental study shows that the biomass liveweight of the roots of the cured-tobacco plants after nanometer synergistic treatment is implemented on conventional fertilizers is obviously increased; and the increasing rate of the accumulation volume of potassium in single plant is 21.35 percent. Field test result shows that the potassium content of the tobacco leaf is obviously increased and the quality of the tobacco leaf is improved.
Description
[0001] technical field [0002] The invention belongs to the tobacco leaf quality regulation technology in the field of tobacco agriculture, and in particular relates to a nanometer synergistic method for increasing the potassium content of tobacco leaves. Background technique [0003] Tobacco is an important economic crop in my country and a typical potassium-loving crop, which has a large demand for potassium. Potassium not only affects the growth and development of tobacco, but is also one of the important indicators for evaluating the quality of tobacco leaves. A higher potassium content in tobacco leaves can improve the combustibility and smoldering fire holding power of tobacco leaves, which is of great significance for improving the color and taste of tobacco leaves. Compared with foreign tobacco leaves, the potassium content of Chinese tobacco leaves is quite different. The potassium content of foreign high-quality tobacco leaves is mostly about 3.5%, while the po...
