Description
Technical field
The present invention relates to agricultural plantation technology field, in particular it relates to a kind of STEVIA REBAUDIANA plantation herbicide and preparation side
Method.
Background technology
STEVIA REBAUDIANA is composite family perennial root herbaceos perennial, and original producton location is in South America subtropical zone.The root of STEVIA REBAUDIANA, stem,
Contain stevioside in leaf.Stevioside has high sugariness（For 200 ~ 300 times of sucrose）, it is low in calories（Only the 1/ of sucrose
300）The characteristics of, and be improved blood sugar, reduce blood pressure, the effect for enhancing metabolism, to obesity, diabetes, heart disease, dental caries
Tooth etc. has certain booster action, thus increasingly causes the concern and attention of people, becomes " the after sucrose, synthesis sugar material
Three sugar sources ".
The cultivated area of STEVIA REBAUDIANA also constantly expands, and supply falls short of demand.STEVIA REBAUDIANA product is widely used in medical science, food
Product additives industries.At present, the mainly STEVIA REBAUDIANA blade of STEVIA REBAUDIANA application, and the stem of STEVIA REBAUDIANA, root are all dropped.STEVIA REBAUDIANA
Effect be generally recognized in the world, concrete effect is as follows：1) STEVIA REBAUDIANA can provide enough organic for seed sprouting
Nutrition, makes seedling sturdy, well-grown.2) STEVIA REBAUDIANA can promote seedling root system development, be conducive to the transplanting and management in future.
3) sweetleaf chrysanthemum and cane powder can play effective inhibitory action to root-knot nematode.4) sweetleaf chrysanthemum and cane powder can
To suppress the generation of root rot, droop.5) STEVIA REBAUDIANA cane is the accessory substance of STEVIA REBAUDIANA production, and waste discarding is only done at present,
Cost is relatively low.
In recent years, with the increase of STEVIA REBAUDIANA demand, cultivated area is also constantly expanding, south to Hainan, north to black dragon
There is plantation in river, east to East Coastal, west to Tibet.With the expansion of cultivated area, the problem that planting process runs into also is put
Greatly, wherein, it is exactly one of problem demanding prompt solution to go to cut weeds.
Herbicide species in the market is a lot, but is made up of compound.The characteristic that compound has in itself is right
Preferably effect is played in weeding.It is little in recent years with the abuse of the herbicide by made by compound, make weeds remove chemistry
Careless agent generates the resistance to the action of a drug, loses herbicide effect；Big then the balance of destruction periphery ecological environment, the herbicide containing carcinogenic components
Because chemical residual or application cause threat to the health of people.Therefore develop a kind of natural, pollution-free, and herbicidal effect
Herbicide that is good, being all safe from harm to environment and the mankind replaces the disaster that chemical herbicide in the market is current research
Topic.
The content of the invention
For defect of the prior art, it is an object of the invention to provide a kind of STEVIA REBAUDIANA plantation herbicide and preparation side
Method, can not only effectively go out weeds, moreover it is possible to weed seed is played a part of to suppress teething, and the herbicide safety is without dirt
The characteristics of dye, human body will not be damaged, with higher using value.
The present invention solves technical problem and adopts the following technical scheme that：
