Description
Technical field
The present invention relates to a kind of agricultural chemicals type wheat seed dressing agent and preparation method thereof, belong to seed dressing technical field.
Background technology
Wheat is one of main cereal crops of China.Along with the continuous change of natural conditions, the factor such as temperature, disease affects the increasing both production and income of wheat.Particularly in seedling stage, wheat absorb nutrient and resistance against diseases weak.Seed dressing is processed into by bactericide, chelated microelement, plant growth regulator etc., is wrapped in the surface of the seed after can diluting.Seed dressing is the basis of crop nutriment whole breeding time supply, not only can ensure that one broadcasts full stand, and be the key measure preventing some damage by disease and insect He provide some nutriment of crop.Seed dressing uses before sowing, and save time, saving of labor, to save money, can promote plant growth, make that its root system is powerful, strong stress resistance, can protect product, increase production, economy, ecological benefits are remarkable.
Chinese patent document CN104430424A (application number: 201410682305.5) disclose a kind of composition containing Fungicidal active substance, wherein the ratio of weight and number of active component Difenoconazole and carbendazim is 20:1 to 1:20, in composition, active component weight percentage is 1 ~ 90%, said composition is used for preventing and treating the plant disease caused by disease fungus, especially the leaf spot of various vegetables and fruit tree is prevented and treated, ring spot, anthracnose, powdery mildew, the disease such as rust and scab, obviously be better than the control efficiency of single dose, save Difenoconazole and carbendazim drug cost, alleviate the impact on environment.Although this patent document discloses the information of Difenoconazole and carbendazim compound sterilizing, not yet there is the open report being applied to seed dressing.
Chinese patent document CN103609590A (application number: 201310500654.6) disclose a kind of wheat seed dressing agent that can improve wheat seeding rate and increase yield, relate to agricultural technology field, mix 100kg wheat seeds and need following component and consumption: alpha-cypermethrin 100-140ml, 25% Tebuconazole wetting powder 20-40g, compound sodium nitrophenolate 2-6ml, potassium dihydrogen phosphate 160-180g, water 2-4kg.Although this wheat seed dressing agent is containing macroelement phosphorus and potassium, and has sterilizing function, lack the necessary trace element of wheat growth, and its farm chemical ingredients is large to environmental influence.
Chinese patent document CN1188596A (application number: 97107346.5) disclose multi-effect seed-dressing agent for crops, outside the micro-fertilizer in existing wheat seed dressing agent, growth regulator, newly add in bactericide, insecticide and production technology and increase chelating operation, the main chemical agent increased has triadimefon, Furadan, chlormequat, paclobutrazol, amino acid, magnesium sulfate and borax.Triadimefon, Furadan chemical agent is added in this multi-effect seed-dressing agent, although have kill soil insect, strong sprout of keeping a full stand of seedings, control main diseases and insect pests effect, but there is the problem of degrade residual, contaminated soil simultaneously, and its chelating operation is simply to be used as dressing by chelating agent, cannot effective chelating Meso-and micro-nutrients, greatly reduce the effective rate of utilization of medium trace element.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of gentle agricultural chemicals trophism seed dressing and preparation method thereof efficiently.This seed dressing, and to have wheat seed without poisoning, low toxicity, good to environment compatibility wheat seed breeding time again: strong sprout, short root, increase tiller, short photosynthetic effect, seed dressing wide spectrum, with low cost.Solve high toxicity that the prevention and elimination of disease and pests that runs in wheat planting process often uses, difficult degradation agricultural chemicals is difficult to the harm of environment, medium trace element problems such as making full use of.
