Abstract
The invention relates to a wheat seed dressing agent with growth regulation function, which consists of triazole substances, quaternary ammonium salts, manganese, zinc, boron, iron and other trace and major essential element components which have important promotion and influence on the germination, growth and seed setting of wheat, can obviously improve the germination rate and tillering number of wheat, improve the growth form and the environmental adaptability, and improve the yield.
Description
What the present invention relates to is a kind of wheat seed dressing agent with plant growth regulation.
Known plant growth regulator has nitrogen heterocyclic ring compounds, quaternary ammonium compound and microelement kind material etc. dissimilar by the different of action principle and application target at present; Have again by period of using and using method and to handle soil environment, handle seed or to impose on the different of plant in vegetative period etc.For example Chinese patent 88101649.7A disclose a kind of by triazole class compounds and quaternary ammonium salt and or phosphinic acid compounds and or replace the plant growth regulator that 12 carbon diolefin compounds are formed, can be used for to the processing of soil, seed and or spraying plant.Chinese patent 89103519B is disclosed to be a kind of chemical fertilizer of being made up of the required various trace elements of plant growing.Chinese patent 85104629B is disclosed then to be a kind ofly to be made up of imidazoles and quaternary ammonium compounds, for the growth regulator that use vegetative period behind cereal and the rice seedling.Because they all are to act on plant from a certain special angle, to reach desirable specific purpose, pretending with scope has bigger limitation.Except that first part of document introduction can have the more occupation mode, all the other then mostly are should be in the plant in vegetative period in the mode of spraying.This method of application also must bring the medicament waste many, the deficiency that consumption is big except that very not convenient.
The object of the present invention is to provide a kind of sphere of action comprehensive, and consumption is few, wheat growth easy to use is regulated and is used seed dressing.
Wheat seed dressing agent of the present invention includes the composition of multiple action modes such as necessary multiple trace of triazole class compounds, quaternary ammonium salt material and plant growth with plant growth form regulating action and macroelement, its composition (weight %) is: manganese sulphate 35-45, zinc sulphate 20-30, borax 0.4-1, quaternary ammonium salt 1.5-3, triazole class compounds 0.1-1, the phosphate 1-25 of monovalence metal species material, and carrier inserts surplus in case of necessity.
Research is observed and is found that the factor of crops external environment when seed germination all can have significant effects to the crop whole growth phase.Therefore according to wheat growth characteristic and needs, promptly impose favourable and desirable environmental influence period in its sprouting and often can have the effect of getting twice the result with half the effort.Compositions such as the manganese in the seed dressing, zinc, boron be wheat growth essential but trace element that easily lack usually in the soil.But various quaternary ammonium salt and or triazole class compounds then are the present compositions of known coordinate plant growth form, for example wherein can make plant cane wall thickening and strong more solid, and its growing height of controlled, strengthen lodging resistance; Also can increase the tiller number of crop, improve effects such as adaptive capacity to environment such as heat resistanceheat resistant, cold-resistant, drought resisting and anti-salt, all be crucial for wheat.The test show in various quaternary ammoniums, with N, N, the chloride (being commonly called as chlormequat) of N-trimethyl-N-2-chloroethyl ammonium, in the triazole class compounds with the 1-(4-chlorphenyl)-2-(1H-1,2, the 4-triazol-1-yl)-4,4-dimethyl-amyl alcohol-3 (abbreviation paclobutrazol) is best.The phosphate of monovalence metal species materials such as ammonium phosphate, potassium phosphate or potassium-ammonium phosphate is the fertilizer of using always, necessary trophism composition during for wheat seeds sprouting.Because all less as the general usage amount of seed dressing that the processing seed is used, evenly dispersity is then had relatively high expectations, the carrier material that therefore can suitably use fillibility in case of necessity is as " dilution " agent.In various carrier inserts commonly used,, except that cheap and easy to get, also can have the effect of microelement-supplementing iron to use ferrous sulfate for well.
Also be appreciated that thus, the major requirement in the preparation of the above-mentioned seed dressing of the present invention is to make it as far as possible fully levigate and mix, both can guarantee to save dosing under the prerequisite of result of use, also can reduce or avoid because of grain thickness uneven and or incomplete mixing to cause the effect quality to differ and or even phenomenon such as local poisoning poisoning.For example the less composition of consumption abundant mixing earlier in when preparation can be with various components goes dilution with the big component of consumption more gradually, and is full and uniform with what guarantee to mix.
When seed dressing is used, puddle evenly and can broadcast sowing with wheat seed again after seed dressing of the present invention can being separated mixing with about 10 times of amounts water-soluble usually.Because the wheat seeds of handling with seed dressing of the present invention can obtain growing required and to the influence of its favourable many-sided factor at duration of germination, so can obtain very significant effect with less consumption.For example handle the ratio of wheat kind 25-30 kilogram in 500 grams with above-mentioned seed dressing of the present invention, small plot experiment is made in Henan Province in the seed dressing back, compare with the control group under the same management condition, the wheat bud ratio brings up to 97% by 85%, tillering capacity brings up to 4.2% by 3.1%, the growing period internode shortens, and cane is sturdy, does not have lodging and takes place.Individual plant or fringe rate bring up to 4.10% by 2.90%, and thousand kernel weight is brought up to 39.15 grams by 36.5% gram, and per mu yield increases by 75 kilograms, and rate of growth reaches 30%.Make 150 mu of scale-ups in the Pengshan County, Sichuan Province, comparing thousand grain weight of wheat with control group increases by 1.1 grams, and per mu yield improves 45.2 kilograms, and rate of growth is 11.5%.
Below introduce some examples, but scope of the present invention is not limited in following example as the above-mentioned seed dressing of the present invention.The consumption of each component is weight % in each example, and what the quaternary ammonium salt in the component was selected for use is aforesaid chlormequat, and what triazole compounds was selected for use is aforesaid paclobutrazol.
Example 1
Manganese sulphate 40%, zinc sulphate 25%, borax 0.5%, chlormequat 2%, paclobutrazol 0.5%, potassium phosphate 20%, ferrous sulfate surplus.The abundant levigate back of each component stirs with other component more earlier with the abundant mixing of borax, chlormequat and paclobutrazol.
Example 2
Manganese sulphate 35%, zinc sulphate 30%, borax 0.4%, chlormequat 3%, paclobutrazol 0.1%, ammonium phosphate 25%, ferrous sulfate surplus.All the other operations are with example 1.
Example 3
Manganese sulphate 45%, zinc sulphate 20%, borax 1%, chlormequat 1.5%, paclobutrazol 1%, ammonium phosphate 1%, ferrous sulfate surplus.All the other operations are with example 1.
Example 4
Manganese sulphate 42%, zinc sulphate 26%, borax 0.8%, chlormequat 0.8%, paclobutrazol 0.8%, ammonium phosphate 24%, ferrous sulfate surplus.All the other operations are with example 1.
