Description
Technical field
The present invention relates to agricultural fertilizer, particularly a kind of Flower Bud Differentiation of Strawberry high potassium controlled release special fertilizer material in early stage, the invention still further relates to the preparation method of this Flower Bud Differentiation of Strawberry high potassium controlled release special fertilizer in early stage.
Background technology
Along with the development of science and technology, conventional chemical fertilizer and agricultural chemicals arise at the historic moment, and peasant's a large amount of uses year after year, make soil profitable strain sharply reduce, and in soil, nutrient (N, P, K) runs off serious.Strawberry is a kind of happiness potassium crop, and the supply of potash fertilizer directly affects the yield and quality of strawberry.For in general soil, essential nutrient contents is that nitrogen is put down, phosphorus rich, the deficient scarce situation of potassium, and potash fertilizer is on the low side, often causes output not high, and quality declines, and particularly fruiting period is partially short, and fruit type is little, yields poorly.Fruit expand and the maturation painted phase will be noted supplementing potash fertilizer more, simultaneously because strawberry growth cycle is longer, reach 9 months, must select to use the long base fertilizer of fertilizer efficiency, to ensure that strawberry whole vegetative period is to the demand of nutrient, the increasing both production and income of such guarantee strawberry.
What the strawberry cultivating fertilising overwhelming majority continued to use is traditional fertilization way, and base fertilizer adds later stage fertilising, and base fertilizer generally all uses farm manure and composite fertilizer.Farm manure, its feature has raw material sources wide, and quantity is large; Nutrient is complete, and content is low; Conventional natural manure kind has green manure, human excrement, barnyard manure, compost, makes compost, biogas manure and sludge and refuse etc., and fertilizer efficiency grow late, could must be absorbed after microbial decomposition conversion by plant; Soil building is effective.Composite fertilizer, use traditional nitrogen, phosphorus, potassium element Chemical Mixed Fertilizer exactly, the use of these fertilizer, cause the shortage of some nutrient (as nitrogen, potassium) on the one hand, cause the waste of nutrient (as phosphorus) on the other hand, life-time service can make soil compaction, is unfavorable for the growth of strawberry.
Therefore, the Flower Bud Differentiation of Strawberry high potassium controlled release special fertilizer in early stage researching and developing a kind of high potassium controlled release simultaneously becomes a urgent and important job.
Summary of the invention
The first object of the present invention is the weak point overcoming above-mentioned existing background technology, and provides a kind of Flower Bud Differentiation of Strawberry high potassium controlled release special fertilizer in early stage.
The second object of the present invention is the preparation method providing this Flower Bud Differentiation of Strawberry high potassium controlled release special fertilizer in early stage.

Preferably, be made up of following component: 380-450 parts by weight of urea, 60-90 parts by weight of phosphoric acid one ammonium, 200-240 weight part Repone K, 100-140 weight part plant ash, 3-4 weight part potassium solubilizing bacteria, 20-40 parts sulfuric acid magnesium, 3-4 parts sulfuric acid zinc, 12-16 weight part Sodium salts humic acids.
Further, be made up of following component: 405 parts by weight of urea, 76 parts by weight of phosphoric acid one ammoniums, 210 weight part Repone K, 130 weight part plant ash, 3 weight part potassium solubilizing bacterias, 20 parts sulfuric acid magnesium, 4 parts sulfuric acid zinc, 15 weight part Sodium salts humic acidss.
Further, be made up of following component: 460 parts by weight of urea, 80 parts by weight of phosphoric acid one ammoniums, 240 weight part Repone K, 100 weight part plant ash, 4 weight part potassium solubilizing bacterias, 30 parts sulfuric acid magnesium, 3.5 parts sulfuric acid zinc, 16 weight part Sodium salts humic acidss.
The second object of the present invention is reached by following measure: the method for the Flower Bud Differentiation of Strawberry high potassium controlled release special fertilizer in early stage described in preparation, it comprises the steps:
1) take potassium solubilizing bacteria and Sodium salts humic acids by weight, add 30 times of water dissolution that weight is the gross weight of potassium solubilizing bacteria and Sodium salts humic acids, obtain spray solution;
2) plant ash is shattered, cross 30 mesh sieves;
3) plant ash after urea, monoammonium phosphate, Repone K, pulverizing, magnesium sulfate, zinc sulfate are counted to resend respectively by weight and are fully stirred into agitator, then granulation;
4) by step 1) spray solution of gained sticks to step 3 through atomization) particle surface of gained, dry, obtain Flower Bud Differentiation of Strawberry high potassium controlled release special fertilizer in early stage.
Described urea is small-particle type, and described raw produce is commercially available prod.
The invention has the advantages that: 1, Bian Repone K, plant ash and potassium solubilizing bacteria with the use of, permanently effective benefit potassium effect can be ensured; 2, reasonable ratio, has good economy and ecological benefits; 3, insoluble slowly available potassium in soil can be dissolved out by potassium solubilizing bacteria on the one hand, and increase the source of potassium element in soil, on the other hand, potassium solubilizing bacteria also acts on plant rhizosphere soil, activating rhizosphere soil microenvironment; 4, the present invention proceeds from the reality, and only needs single-dose application, with low cost, and suit large area to popularize use.
