Description
Technical field
The invention belongs to the arviculture technical field, be specifically related to a kind of rape element in strong sprout and preparation method thereof, this, element was mainly used in rape production in strong sprout, to improve the healthy and strong degree of rape seedling, improved the anti-adversity ability of seedling, thereby improved yield of rape.
Background technology
Growth and development of plant, as the formation of division, elongation, differentiation and the organ of cell and blossom and bear fruit, ripe, old and feeble, come off etc., all with the nutritional status of plant and its body in the plant hormone that produces closely related.The plant-growth regulator of synthetic also has above-mentioned functions to growth and development of plant.As promote seedling to take root, break seed dormancy and accelerate seed germination, regulate plant type, regulate bolting, flowering time, adjusting male and female sex differentiation and development, regulate fruit enrich ripe, prevent that organ from coming off, delaying senility etc.Along with science and technology and Agricultural Development, utilization plant-growth regulator regulation and control growth and development of plant and output form, and become indispensable important measures in the agriculture production gradually.Both at home and abroad the research of plant-growth regulator and use as 21 century agricultural realize one of major measure of super high-yielding.On rape was produced, what research application at present was maximum was in the 3 leaf phases of rape seedling, to spray paclobutrazol.But growth regulators such as long-term, a large amount of, single use such as paclobutrazol can cause medicament residual quantity in soil to increase on the one hand, the long effect of tangible two secondary controls occurs, even may influence the 3rd batch of crop; On the other hand because modulator effect modes such as paclobutrazol single (having only the effect of control growth of seedling) can only be applied to rape seedbed and the more prosperous rape seedling of growth.As seen, this class growth regulator can not satisfy the requirements at the higher level that modern rape production proposes output to the regulating and controlling effect of rape seedling.
It is 200510038018.1 (publication number is CN1663392A) patent publication us that the applicant retrieves a application number related with the present invention, a kind of multi-functional plant growth regulator and preparation method thereof is roughly disclosed, its composition component is that vigor element, bisulfite are received, paclobutrazol, help strong element, acetylsalicylic acid, dispersion agent N, Sodium dodecylbenzene sulfonate and dodecyl phenenyl sulfate, and it is said to grow to the strong sprout, the regulation and control that comprise ten various crop such as paddy rice, wheat, cotton and rape produces effect.But the specification sheets of this patent application does not have full disclosure wherein composition and the source of the plain and dispersion agent N of important component such as vigor, cause the public can't implement its invention and reach the effect shown in the specification sheets, there is no the application report on the rape simultaneously in the embodiment, all do not have experimental data among all embodiment.
Summary of the invention
The objective of the invention is to overcome the drawback of traditional rape production and the defective of prior art, provide a kind of rape seedling overground part that can delay to a certain extent to nourish and grow, promote the underground part root growth, can satisfy the needs of rape seedling normal growth growth again to main nutrient elements, thereby cultivate the rape element in strong sprout of healthy and strong seedling, clear and definite its preparation method and application conditions, to improve the anti-adversity ability of rape seedling, improve Semen Brassicae campestris output.
The present invention realizes by following technology:
A kind of growth promotor composition for making seedlings sturdy of cole, in parts by weight, its component is as follows:

(4) take by weighing in copper sulfate, the ammonium molybdate adding step (3) uniform mixing respectively by formula ratio;
(5) be the Powdered of homogeneous after making the mixing composition thorough mixing of step (1) to (4).
As a kind of preferred version, growth promotor composition for making seedlings sturdy of cole of the present invention, in parts by weight, its component is as follows:
50 parts of potassium primary phosphates;
25 parts of boraxs;
20 parts of 15% paclobutrazol wettable powder paclobutrazol;
2.5 parts in zinc sulfate;
1.5 parts of manganous sulfates;
0.5 part in copper sulfate;
0.5 part of ammonium molybdate.
A kind of method for preparing growth promotor composition for making seedlings sturdy of cole, in parts by weight, its component is as follows:
Potassium primary phosphate 30-55 part:
Borax 17.5-32.5 part:
15% paclobutrazol wettable powder 16-32 part:

In rape of the present invention element in strong sprout, the main points of its invention be this prescription under the prerequisite of retained part plant-growth regulator, strengthened compounding application with rape desired nutritional element.Promptly in formula for a product, plant-growth regulator is made finished product as macronutrients such as the required phosphorus of 15% paclobutrazol wettable powder (claiming PP333 again) and rape, potassium with the component that micronutrient elements such as zinc, copper, manganese, molybdenum, sulphur, boron are formed, thereby play effect plant-growth regulator and nutritive element combination.
Technical scheme is as described in " embodiment " more specifically.
Above-mentioned plant-growth regulator paclobutrazol and nutritive element are commercially available, and wherein paclobutrazol is 15% wettable powder, and other nutritive elements are the chemical reagent of chemical pure level.At suitability for industrialized production element in strong sprout, when carrying out large scale application, can consider to use industrial raw material reagent, to reduce production costs.Above-mentioned various component is the powdery product of homogeneous after fully mixed.
Compared with prior art, the present invention has following positively effect.
1, growth promotor composition for making seedlings sturdy of cole high-efficiency broad spectrum of the present invention.Content as the paclobutrazol of plant-growth regulator in the growth promotor composition for making seedlings sturdy of cole of the present invention accounts for 20%, phosphorus, the total content of potassium macronutrient accounts for 50%, the content of borax accounts for 25%, micronutrient elements such as zinc, copper, manganese, molybdenum, sulphur account for 5% of total content, and its prescription has satisfied the demand of rape seedling development to greatest extent.
2, the good high efficiency of product result of use of the present invention.This product is there to be just operational material on a small quantity.Compare its amount of application with fertilizer and greatly reduce, per hectare only need be used about the 500-2000 gram.Adopt the combination matching of plant-growth regulator and mineral nutrient element in the rape element in strong sprout, realized the double regulation control of rape seedling formalness feature and internal physiological process, realized quick-actingly combining with holding to imitate, overcome and singly executed plant-growth regulator or inharmonious, the incomplete shortcoming of single fertilise, finally present rape plant type compactness, nutrient utilization ratio height is brought into play the comprehensive effectiveness of multiple nutrients composition evenly.
3, the present invention has very strong specific aim.Foliage-spray product effect of increasing production of the present invention is obvious, has very high practical value.This be since the rape seedling in the phase of surviving the winter, the growth of its root system and energy (works) power that absorbs nutritive substance weaken, the resistance reduction is difficult for safe overwintering, thereby directly influences the Semen Brassicae campestris yield and quality.Behind foliage applying rape of the present invention element in strong sprout, very fast performance whole synthesis effect.It not only can regulate and control rape plant Endogenous Hormones, has replenished nutritions such as effective potassium, phosphorus, boron, zinc, manganese, sulphur, copper, molybdenum simultaneously, has satisfied the demand of endogenous hormones change to nutritive element, has increased the vigor of balance compound system.Therefore, rape being cultivated abilities such as strong sprout, raising resistance achieves noticeable achievement.
