Fig. 1 is the schematic flow sheet of notoginseng soil disinfection method of the present invention.
Embodiment
The invention provides many applicable creative concepts, this creative concept can be reflected in a large number of in concrete context.The specific embodiment described in following embodiments of the present invention only as the exemplary illustration of the specific embodiment of the present invention, and does not form limitation of the scope of the invention.
Below in conjunction with accompanying drawing and concrete embodiment, the invention will be further described.
The invention provides athomin purposes as fumigant in notoginseng soil disinfection.Athomin refers to from horseradish Armoracia rusticana (Lam.) Gaertn., B.Mey.etScherb. the class secondary metabolite extracted in crucifer is waited, chemical constitution all contains-N=C=S active group, can volatilize at normal temperatures, outward appearance is like the liquid of oily.Athomin is applied to the sterilization of notoginseng soil as fumigant, has good inhibition to the soil-borne pathogen in soil, to root nematode, there is good control efficiency, realize the sterilization of soil.Because athomin comes from natural natural products, the characteristic of itself can make it drop to minimum to the degree of environment; Its main component allyl group isosulfocyanate is safer to people, is easy in the environment decompose, and uses the rear possibility to environment very little, also obviously can not affect the ecological balance of local, environmental friendliness.
Particularly, as shown in Figure 1, notoginseng soil disinfection comprises the steps: first to process soil, namely carries out soil treatment step S1100.Concrete operations are: by planted pseudo-ginseng soil deep tillage airing after ridging, and regulate the absolute water content of soil to make it keep moistening.Preferably, described row spacing 1.8m, ridge height 15-25cm (that is, the degree of depth of the ditch between two ridges is 15-25cm).
After soil treatment, fumigant can be carried out and spray step S1200: the dilute aqueous solution of athomin is evenly sprayed on soil after treatment.In one embodiment of the present of invention, obtain after 20% athomin aqua is diluted 1000 times by the dilute aqueous solution of described athomin.The fountain height of described athomin dilute aqueous solution suitably can adjust according to the situation of notoginseng soil, and usually, the dilute aqueous solution 5-10kg spraying described athomin in the soil after every mu of described process can meet the sterilization demand of soil.
Fumigant carries out sealing fumigating step S1300: with transparent membrane, earth's surface is sealed 7-15 days after spraying, and forms confined space.Along with the rising of temperature in confined space, the athomin volatilization in soil, forms certain concentration, fumigates soil.In general, the time of soil-fumigating is longer, and it is more abundant that soil fumigant plays drug effect, and the effect of soil-fumigating is better, but long fumigation time can extend the soil disinfection cycle, delays the sowing time of pseudo-ginseng.Applicant finds after deliberation, by better for its fumigating effect during notoginseng soil-fumigating 7-15 days, does not affect the sowing of pseudo-ginseng simultaneously.
After having fumigated, also need the medicament that may remain in soil after soil-fumigating to distribute the sowing just carrying out pseudo-ginseng, otherwise easily make the crop of transplanting produce poisoning.For this reason, sterilization method of the present invention comprises fumigating gas checking procedure S1400 further.That is, complete sealing stifling after, soil is opened wide 4-7 days by the transparent membrane removed on earth's surface, the seed of transplanting the fructovegetative seedling of vegetables or sprouting afterwards after stifling in soil, observe gas whether arrange clear complete.In the present invention, use the cucumber seeds of tomato plants and firm rudiment, after tomato seedling and Seed Germination in Cucumber, the equal compared with normal of growth, namely show to have fumigated, the gas produced in stifling process disperses completely, can treat kind of a pseudo-ginseng.
Suitable soil moisture is very crucial for successful soil-fumigating, and it can make the seed coat of weed seed in soil soften, and breaks seed dormancy; Make the spore germination of soil-borne disease fungal pathogens, line eggs hatching, even if pest is in " growth " state.Meanwhile, suitable humidity can make fumigant play fumigating effect better, also affects the movement of fumigant in soil simultaneously.Through lot of experiments, applicant finds, when the absolute water content of soil is 15-25%, can play the fumigation action of chloropicrin capsule preferably.In particular, when the absolute water content of soil is 20%, fumigating effect is best.
Suitable soil temperature equally also has remarkable impact to fumigating effect.In general, temperature is higher, and the volatility of fumigant is larger, limited airtight in vapour pressure also larger, stifling effect is also relatively better.On the other hand, temperature is higher, and target pest is tending towards active, and respiration increases, thus more easily occurs poisoning.Generally, when temperature is higher than 10 DEG C, if the temperature of soil or environment is higher, the effect of medicament soil-fumigating is better.If but temperature is too high, fumigant moves too fast, this will speed up the escape of fumigant.Find after deliberation, the temperature of optimum soil-fumigating is 15cm degree of depth soil temperature is 15-20 DEG C, and at this moment target organism is just in time in " living " state, thus is more easily killed.In the present invention, the temperature of soil-fumigating is arranged on 18-25 DEG C.
In stifling process, distributing of fumigant should be reduced, to play the drug effect of fumigant to greatest extent as far as possible.At present, measure production mainly taked has increases the dispenser degree of depth, suppression soil, the water content increasing soil, the content of organic matter improving soil and covering impermeable membrane etc.In the present invention, the transparent membrane of employing is that plastic membrane of polyvinyl chloride is to reduce distributing of fumigant.The mechanical strength of polyvinyl chloride film is larger, ageing resistace is better, can use under sunburst, and the light transmission of polyvinyl chloride film is good, good heat insulating, heat effect also comparatively remarkable, can ensure that the soil warming sealed makes chloropicrin capsule evaporate into gas in soil, intercept leaking of chloropicrin gas simultaneously.There are some researches show, complete impermeable plastic film > impermeable plastic film > high-density plastic film > Low density plastic film is followed successively by fumigant barrier power, therefore, preferably high density plastic membrane of polyvinyl chloride is adopted in the present invention.
It should be noted, the present invention will be described instead of limit the invention for above-described embodiment, and those skilled in the art can design alternative embodiment when not departing from the scope of claims.In the claims, any reference symbol between bracket should be configured to limitations on claims.Word " comprises " not to be got rid of existence and does not arrange element in the claims or step.Word first, second and third-class use do not represent any order, can be title by these word explanations.
