Description
Technical field
The present invention relates to herbicide, and in particular to a kind of vegetable source natural inhibitor for hawthorn orchard malignant weed.
Background technology
Malignant weed is predominantly perennial, lignifying weeds, and they not only fight for sunlight, moisture and nutriment with fruit tree, and
And make soil hardening, the respiration of fruit tree root system is hindered, and a variety of pest and disease damage diseases are propagated, it is very harmful to fruit tree.Fruit tree
Average underproduction 15-20%, causes very big economic loss to orchard every year after being endangered by malignant weed.
The most directly effective method of control weeds is still largely to use chemical herbicide at present, and herbicide accounts for whole agricultural chemicals
The 2/3 of dosage.Chemical herbicide is mostly non-natural existing artificial synthesized material, and nature is typically without corresponding microbial degradation
Approach, thus cause fruit tree and soil to have a large amount of degradation of pesticide residual hazards, accumulate in the environment, and biology is recycled into by material
Chain.Chemical herbicide after a certain period of use time, often makes weeds develop immunity to drugs, and forces people develop and use medicine strength more violent
Herbicide, this is tantamount to drink poison to quench thirst.Chemical herbicide for malignant weed is mostly to go out natural disposition, it is few it is selective very
Strong herbicide.For malignant weed agriculturally also without very good prevention and controls, required at present in production using " to prevent
Based on, integrated control " policy.Often not only turn into the number one killer of honeybee with honeycomb, chemical herbicide by orchard, cause
The serious financial consequences of beekeeper, while also turn into the potential safety hazard in nectar source.The pressure of artificial synthesized herbicide is growing day by day how
Developing the herbicide of ecological safety of new generation turns into urgent problem.
The content of the invention
The technical problems to be solved by the invention are：A kind of hawthorn orchard malignant weed plant source inhibitor is provided.
The present invention technical solution be：A kind of hawthorn orchard malignant weed plant source inhibitor, formula
Including：
（1）25 parts of Rabdosia rubescens；
（2）30 parts of tussilago；
（3）15 parts of hooker winghead root；
（4）30 parts of akebi；
Preparation method：
Formula each component is dried to constant weight in 60 DEG C, crushes and mixes, cross 20 mesh sieves, by weight adding 75% ethanol, 45
Ultrasonic extraction 60min at DEG C, medicinal extract is obtained after decompression compression, add water to abandon insoluble matter after settling, obtain filtrate, must be concentrated after being concentrated under reduced pressure
Liquid, finally concentrate is spray-dried, produced.
The solution have the advantages that：Inventive formulation is deployed into weeds suppression in proportion using natural herbal as source material
Agent, by reasonable component, inhibitor shows higher inhibitory activity, and this formula herbicide selective is strong, and herbicidal effect is good, people
Poultry honeybee is harmless, and environmentally safe, natural microorganisms can carry out natural degradation to it, to soil without attachment, not influence water
Matter, air, it is a kind of ecological safety type herbicide.
Embodiment
Formula composition（By ratio of weight and the number of copies）：
（1）25 parts of Rabdosia rubescens；
（2）30 parts of tussilago；
（3）15 parts of hooker winghead root；
（4）30 parts of akebi.
Preparation method：
Formula each component is dried to constant weight in 60 DEG C, crushes and mixes, cross 20 mesh sieves, be incorporated by ratio of weight and the number of copies, add
75% ethanol, ultrasonic extraction 60min at 45 DEG C, after decompression compression medicinal extract, add water to abandon insoluble matter after settling, obtain filtrate, decompression is dense
Concentrate is obtained after contracting, finally concentrate is spray-dried, obtains weeds inhibitor of the present invention.
Test method：
After additive of the present invention is dissolved with a small amount of 90% ethanol, with water with 1:3000 times of dilutions, before orchard weed goes out stubble
Uniformly sprayed once into soil, in uniformly being sprayed once into weeds and soil before fruit tree blooms, in ripening of fruits
Uniformly sprayed once into weeds and soil.Experiment orchard seeds are thornbuss, and testing ground area is 5 ㎡, and control ground area is 5
㎡（Any herbicide is not sprayed）, two pieces of samples close to land occupation condition is identical, plants hawthorn species and quantity is consistent, in orchard
Weeds are based on the malignant weeds such as Drilgrass, the rhizome of nutgrass flatsedge, johnson grass, artemisiifolia, annual bluegrass.
Result of the test：
After spraying for the first time, experimental field weeds go out a batch date and are later than comparatively 10 days, and it is only 20% compareed to go out batch rate；
Hawthorn florescence, experimental field weed growth rate was 40% comparatively, and weed growth rate is comparatively after spraying for the second time 7 days
20%；The hawthorn maturity period, experimental field weed growth rate was control 30%, and weed growth rate is comparatively after spraying for the third time 7 days
10%；Experimental field hawthorn yield is higher than comparatively yield 13% after autumn harvest.
Result of the test can be seen that, after inhibitor of the present invention, each stage malignant weed inhibition is notable, and does not influence
Fructus Crataegi yield.It is effective to illustrate that this is formulated for the malignant weed safe prevention in orchard.
Technical scheme be carry out fruit tree nixed planting research when have been surprisingly found that, Rabdosia rubescens, tussilago, akebi,
Hooker winghead root is when miscegenation is under thornbuss by a certain percentage to malignant weed（Drilgrass, the rhizome of nutgrass flatsedge, johnson grass, artemisiifolia, annual bluegrass）Have
Stronger gram raw effect, and hawthorn is not influenceed.It is documented that：Rabdosia rubescens main active is Oridonin, winter
Careless B prime etc. is insulted, Zong Han Liang≤80%, there is the function such as anticancer, antibacterial, anti-oxidant, expansion blood vessel；Tussilago main active
For tussilagone, coltsfoot lactone etc., Zong Han Liang≤80%, there is the function such as anti-freezing, antitumor；Akebi main active is neat pier
Tartaric acid, ivy aglycon etc., it is total containing amount≤80%, there is the functions such as analgesia, antibacterial, anti-inflammatory, anticancer, diuresis；Hooker winghead root is mainly lived
Property composition be oleanolic acid, ursolic acid etc., Zong Han Liang≤80%, have antibacterial, anti-inflammatory, heat-clearing, antirheumatic, liver protection, reducing blood lipid,
The functions such as cardiac stimulant.It is rarely reported these four herbal medicine to assemble and is used as herbicide.
