Exemplary illustration, and be not meant to limit the scope of the invention.
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
The invention provides a kind of sterilization method of notoginseng soil, Fig. 1 shows notoginseng soil of the present invention
The schematic flow sheet of sterilization method.As shown in figure 1, the sterilization method is handled soil first, that is, carry out soil treatment
Step S1100.Concrete operations are：Ridging after the soil deep tillage for planting pseudo-ginseng is dried, and adjust the absolute water content of soil
It is set to keep moistening.Preferably, the row spacing 1.8m, the high 15-25cm in ridge (that is, the depth of the ditch between two ridges is 15-25cm).
After soil treatment is finished, you can carry out fumigant landfill step S1200：Chloropicrin capsule is buried in the earth.Its
In, at interval of 10-20cm, a chloropicrin capsule is embedded in soil.In one embodiment of the present of invention, the chloropicrin glue
The specification of wafer is 3-5g.Because chloropicrin is encapsulated in capsule, capsule need to be only buried in the earth, after capsule dissolves,
Chloropicrin therein is discharged, pesticide-germicide effect is played,, can be without any to user's safety without any application equipment
Safeguard is used, and stores convenient transportation；And distributing during fumigating can be reduced, stifling make is played to greatest extent
With.
After fumigant landfill, sealing fumigating step S1300 is carried out：Earth's surface is sealed 7-15 days with transparent membrane, formed
Confined space, chloropicrin capsule dissolving, chloropicrin volatilization therein forms certain concentration, soil is fumigated.Typically
For, the time of soil-fumigating is longer, and soil fumigant performance drug effect is more abundant, and the effect of soil-fumigating is better, still
