Abstract
The invention discloses a matrine-brassinolide suspended seed coating and a preparation method thereof. The content of matrine is 0.01-80% and the content of brassinolide is 0.001-10%. Matrine, brassinolide, dispersing agent, antifreezing agent, film-forming agent, padding, colorant, PH conditioning agent and supplemental deionized water are added into a high shear emulsifying dispersion machine, are uniformly stirred and then are added into a grinding machine for grinding, and then the aqueous solution prepared from PH conditioning agent and thickening agent is added for adjusting the PH value and viscosity, and the matrine-brassinolide suspended seed coating is acquired after the materials are uniformly mixed, stirred and discharged. The suspended seed coating is mainly used for seed pelleting treatment before the planting of the crops, such as, paddy, wheat, corn, cotton, soybean, peanut, beet, sunflower, and the like, and has obvious effects in preventing and controlling soil insects, crop insects and soil-spreading diseases and promoting the growth of plants. The matrine-brassinolide suspended seed coating provided by the invention not only can be manually covered but also can be mechanically covered; the time and labor are saved; compared with the other dosage forms and pesticide application technologies, the matrine-brassinolide suspended seed coating has less pollution to environment and higher pesticide usage.
Description
Technical field
The present invention relates to crops pest, controlling disease, strong sprout, the seed treatment of promotion adjustment growth and system thereof
Preparation Method, is particularly used for matrine-brassinolidesuspension suspension seed coating agent processing seed and preparation method thereof, belongs to biochemical
Pesticide field.
Background technology
Seed coat agent is the pesticides new formulation combined by pesticide original medicine, film former, filler, related auxiliaries, is to seed
The process new technique being coated, makees at Oryza sativa L., Semen Tritici aestivi, corn and soybean, Cotton Gossypii, Semen arachidis hypogaeae, Radix Betae, Helianthi, Grass Seeds by Aerial Sowing etc.
Be used widely on thing, to preventing and treating subterranean pest-insect such as nematicide, cutworm, crop pest such as aphid, thrips, leafhopper etc. with
And soil-borne disease effect is notable, and time and labour saving, environmental pollution is little compared with other dosage form and pesticide application technology, pesticide is sharp
High by rate.
Radix Sophorae Flavescentis extract mainly has oxymatrine (oxymatrine, C15H24N2O2), matrine (Matrine,
C15H24N2O), Iosmatrine (Iosmatrine, C15H24N2O), sophor-anol (sophor-anol), sophocarpine

Flavone compound, belongs to biological category, is the botanical pesticide of environmental protection, has parasite killing, sterilizes, grows the multiple merit of adjustment
Energy.
Insecticidal action: low to vegetable Kattapillar, vegetable aphid, melon aphid, snout moths larva, ladybug, beet armyworm, striped flea-beetle, diamondback moth
Instar larvae, LANYE moth, fragrant-flowered garlic maggot, yellow palm moth and elm fleautiauxia armata have strong action of contace poison；To black peach aphid, radish aphid, Schizaphis piricola, little wheat aphid
The prevention effect of worm all reaches more than 90%；Acute tonsillitis black to tea, caterpillar, boat type caterpillar, Limacodidae, chi Qu, red spider are admired in the sky on fruit tree
Spider lecanium, chafer, stinkbug etc., on cereal crops, the various pests preventive effect such as mythimna separata, wheat midge and locust is obvious.Matrine
Insect is had tag, stomach toxicity, interior suction, refusing to eat, sterillization, interference decortication, paralysis central nervous system, polypide protein coagulation, worm
The biological activitys such as bromhidrosis hole blocks, insect death by suffocation.
Bactericidal action: to wheat scab, Pyricularia oryzae Cav bacterium, apple anthracnose, the growth of graw mold of tomato mycelia and pathogenic bacteria
Spore germination has obvious inhibitory action；To Rhizoctonia solani, foot stalk skin umbrella, model spy's Bo Lishi corruption enzyme, the raw rotten enzyme of standing grain, melon and fruit corruption
The lawn pathogenic bacterium such as enzyme have certain inhibitory action；There is suppression to the downy mildew on vegetable, powdery mildew, gray mold and epidemic disease make
With.After spraying matrine, the growth of cotton-wilt fusarium mycelia stops completely.The fungicide active ingredient of matrine can suppress bacterium
The biosynthesis of body, can affect again mycelial biological oxidation process, and fungicidal spectrum is wider.
Plant growing promotes function: substantially increase as sprayed process its cotyledon fresh weight of Fructus Cucumidis sativi and dry weight and fresh weight of plant seedlings, moreover it is possible to promote Huang
The rooting effect of Semen Benincasae leaf petiole base.After matrine processes wheat flag leaf, process group blade sugar content is 1.4 times of left sides of comparison
Right, hence it is evident that higher than comparison, the growth of fringe and the accumulation of seed dry to be had important function.
Brassin lactones have take root, promote growth, carry Seedling, strong sprout, keep a full stand of seedings, yellowtop leaf turns green, promote fertilization, protect spend
Fruit retention, promotion Fruit precocity, the disease that alleviates alleviate poisoning, coordination nutritive equilibrium, drought resisting is cold-resistant, reduce pesticide in crop body
The multi-functionals such as residual, enhancing crop anti-adversity.To the dead Seedling caused because of reasons such as continuous cropping, disease, poisoning, freeze injuries, rotten, vertical
Withered, phenomenon of dampinging off first aid effect is notable, uses 12～24 hours and the most substantially takes effect, recovers rapidly life.It is applicable to cereal crops,
Industrial crops, vegetable and fruit etc., promote growth, increase yield.
Brassin lactones is that in steroidal compounds, biological activity is higher, and they are widely present in plant.Plant
In growth promoter each stage, both can promote to nourish and grow, the most beneficially spermatiation.The concentration denier that it works, is high
Effect plant growth regulator, under very low concentrations, can significantly increase the Vegetative growth of plant and promote spermatiation.It
Some physiological actions be presented with some feature of auxin, gibberellins, the basic element of cell division:
1, promote cell division, promote Fruit.Division to cell has obvious facilitation, horizontal to organ
Growth and longitudinal growth have facilitation, thus play swollen megalocarpous effect；
2, Delaying Leaf-Senescence, it is long to protect the green time, strengthens Chlorophyll synthesis, improves photosynthesis, promotes leaf color to deepen to become
Green；
3, break apical dominance, promote sprouting of lateral bud, it is possible to thoroughly lead the differentiation of bud, promote that side shoot generates, increase branch number, increase
Spend more number, improve becoming pregnant property of pollen, thus increase fruit number and improve yield；
Crops are kept a full stand of seedings by the present invention, strong sprout, raising yield have positive meaning.
Summary of the invention
It is an object of the invention to overcome defect of the prior art, the characteristic for matrine, brassin lactones provides
