Test example
Same Tobacco Farm is separated into the 11 pieces small plantation field of homalographic, number consecutively 1-11, in other planting conditions
In the case of identical, respectively at the tobacco seedlings phase of tobacco seedlings, compoiste fertilizer made from embodiment 1-9, fertilising are used in the fields 1-9
Time is the dusk period.Commercially available organic composite example 1, the wherein each doses of experimental plot 1-10 as a contrast are applied in No. 10 fields
It is identical.No. 11 fields do not operate example 2 as a contrast.The micronutrient levels in tobacco leaf is measured after tobacco seedlings harvest and to tobacco leaf
Quality carries out sensory evaluation.
Wherein, the test of Trace Elements in Tobacco uses《Micro-wave digestion-ICP/MS measures micronutrient levels in flue-cured tobacco,
Analysis and testing technology and instrument, the second phase of volume 17 in June, 2011》Shown in method carry out.Test data is shown in Table 1.

By data in table 1 it is found that using compoiste fertilizer provided by the invention, can significantly improve micro in cigarette strain
Constituent content, while the waste of fertilizer will not be caused, due to containing more plant fiber in rabbit excrement, carried out with plant ash
When fermentation, bacterium is more easy to trace element absorb by the potassium oxalate in plant ash to carry out biological fixation, is sterilized by the later stage
After processing, benefit materials remain in fertilizer always, these trace elements after biological fixation are not easy to flow in the soil
It loses, is more easy to be absorbed by cigarette strain.Simultaneously, it can be seen that the effect for the compoiste fertilizer that embodiment 5-9 is obtained is more preferable, analysis the reason is that
By the way that silkworm excrement particle is added, trace mineral supplement is in the fermentation process of rabbit excrement and plant ash, and melting effect is more preferable, applies
It is more easy to be absorbed by cigarette strain after fertilizer.
