Abstract
The invention discloses an efficient controlled release fertilizer special for strawberries and belongs to the technical field of agricultural fertilizer. The fertilizer is prepared from 7% resin coated urea, calcium superphosphate, potassium sulfate, humic acid, EDTA chelating zinc, additives and other raw materials. On the basis of an existing high-tower melt granulation compound fertilizer device, a reasonable formula is adopted according to the growth fertilizer needing law of strawberries and the fertilizer supply performance of fertilized soil, the efficient controlled release fertilizer special for strawberries is invented, the production requirement of strawberries can be met, the yield is increased, the color of strawberries can be deepened, and quality is better.
Description
Technical field
The invention belongs to agricultural fertilizer technical field, particularly relate to a kind of high-efficient controlled release Special fertilizer for strawberries.
Background technology
Strawberry is per nnial herb, Rosaceae Fragaria.Strawberry is bright in colour, soft and succulency, aromatic flavour, and sweet and sour palatability is nutritious, has moistening lung and promotes the production of body fluid, the effects such as invigorating the spleen and regulating the stomach, also has higher medicinal and medical value, has certain preventive and therapeutic effect to gastroenteropathy and cardiovascular diseases.Strawberry is strong adaptability, easily breeds, and the cycle is short, output is high, the cash crop that income is fast, not only can carry out commercial production, and also applicable garden plant and potted landscape are viewed and admired.
There are the plantation of strawberry in China Hebei, Shandong and a lot of southern provinces and cities.Strawberry takes up an area more than 1,500,000 mus in the whole nation, is mainly distributed in the ground such as Sichuan, Hebei, Anhui, Liaoning, Shandong.In world's small berries is produced, output and the cultivated area of strawberry occupy first place always.
Strawberry root system is more shallow, and fertilizer sucting ability is strong, to nitrogen, phosphorus, the having the call of potassium.Strawberry is very responsive to nutrient, and excessive use of fertilizer or deficiency all can to grow and output, quality bring detrimentally affect.Strawberry initial stage fertilizer-sucting quantity is few, and Post flowering fertilizer-sucting quantity increases gradually, and along with fruit is constantly plucked, fertilizer-sucting quantity also increases thereupon, particularly maximum to the absorbed dose of potassium and nitrogen.After field planting, Amount of potassium absorbed is maximum, is secondly nitrogen, calcium, phosphorus, magnesium, boron.
Test proves, often producing 1000 kilograms of strawberries needs absorbed nitrogen (N) 8.6 kilograms, 3.6 kilograms, phosphorus (P205), 11.2 kilograms, potassium (K20).
Strawberry happiness potassium nitrophilous, so potassium, nitrogen are extremely important in the Sheng phase of yielding positive results, during potassium deficiency often there is black, brown and dry up then for burning in edge, blade face, and also develop to center between the vein of most of blade, old blade is injured seriously.Illumination can increase the weight of burning of blade, and the blade true leaf handle of burning often develops into brown to burgundy, has mild damage, after wilting gradually.The fruit color of potassium deficiency strawberry is shallow, taste is poor.Strawberry is very responsive to chlorine, and executing chloride fertilizer can affect strawberry quality, should control the use of Chloride fertilizer.
Summary of the invention
For the deficiencies in the prior art, product of the present invention is on the basis of the existing high tower fused melt granulated compound fertilizer device of company, according to the regulation of fertilizer requirement of strawberry growth, in conjunction with the nutrient-supply capacity of fertilized soil, reasonably fill a prescription, a kind of high-efficient controlled release Special fertilizer for strawberries invented, not only can meet strawberry production needs, improve output, strawberry color burn, quality also can be made better.
Technical scheme of the present invention is as follows:
A kind of high-efficient controlled release Special fertilizer for strawberries, material component weight part is as follows: 7% resin coated urea 200-500 part, calcium superphosphate 200-350 part, potassium sulfate 350-600 part, humic acid 20-70 part, EDTA chelated zinc 1-20 part, additive 1-20 part;

To be that main raw material is refining with zinc-amino acid chelate form described EDTA chelated zinc, and have the features such as high dissolving, high-selenium corn, safe and non-stimulating, features good taste, Zn content is 1%.
The viscosity-depression agent of described additive to be mass ratio be 1:1 and fall solvent, wherein said viscosity-depression agent is one or more the mixture in ammonium nitrate, ammonium nitrate phosphorus, magnesium sulfate, magnesium sulfate heptahydrate, described in fall solvent be one or more mixtures in ammonium chloride, ammonium sulfate, potassium sulfate, Repone K, saltpetre.
The particle diameter of above-mentioned all raw materials is all within the scope of 2.00mm-4.00mm.
Preparation method of the present invention, comprises following processing step:
Become fused solution after (1) 7% resin coated urea heating and melting, in fused solution, add calcium superphosphate, potassium sulfate, humic acid, EDTA chelated zinc, additive make mixed slurry;
(2) mixed slurry feeding high tower granulator carries out sprinkling granulation; the granulation material entering prilling tower is sprayed by tablets press; again from high tower decline process; interact with the air resistance risen at the bottom of tower; drop to after carrying out heat exchange with it at the bottom of tower; fall into the granule materials at the bottom of tower, after screening surface treatment, namely obtain high-efficient controlled release Special fertilizer for strawberries.
Preferably high-efficient controlled release Special fertilizer for strawberries, material component weight part is: 7% resin coated urea 250-350 part, calcium superphosphate 220-300 part, potassium sulfate 400-600 part, humic acid 30-50 part, EDTA chelated zinc 5-9 part, additive 4-7 part.
Further preferably, this high-efficient controlled release Special fertilizer for strawberries, material component weight part is: 7% resin coated urea 300 parts, calcium superphosphate 240 parts, potassium sulfate 445 parts, humic acid 50 parts, EDTA chelated zinc 8 parts, additive 7 parts.
High-efficient controlled release Special fertilizer for strawberries of the present invention, has following outstanding feature:
1, nutrient formula of the present invention is reasonable, and product is balanced in nutrition, the medium trace element such as the macronutrient needed containing Strawberry Growth and calcium, magnesium, boron.Have balanced in nutrition, fertilizer efficiency is fast, crop absorption ratio is high, several functions such as improvement soil, culture fertility, strong stress resistance, raising output, oil recovery enhancement etc., is a kind of product with advantages such as high benefit, full nutrition, anti-pollution, improvement soil.
2, the present invention strawberry is caused because of nutritional deficiency and physiological disturbance poor growth, seedling is little, seedling is weak, yellow, albefaction, gingko and malformed fruit etc. have special efficacy, the early ageing of strawberry and dead seedling bad root phenomenon can be suppressed, strengthen disease resistance, anti-continuous cropping, cold-resistant ability.
3, improve fruit-setting rate, extend collecting time, increase income.Fruit is large evenly, fruit shape just, closely knit, bright in colour, the tender and lovely succulence of pulp, sugariness be high, prolongation in ripen in advance 5-7 days is gathered more than 10 days, increases production high yield.
4, because product of the present invention contains humic acids, therefore after using Special fertilizer for strawberries of the present invention, effectively can increase the quantity of soil microorganisms with active, be in the nutrient element of stationary state in activating soil, promote the formation of soil aggregate, increase the gas permeability of soil, eliminate soil compaction, regulate soil acidity or alkalinity, improve soil nutrient status, improve plant recovery of nutrient.
Each component proportion of product of the present invention, according to the regulation of fertilizer requirement of concrete edaphic condition and crop species and different growing, can carry out suitable adjustment, to meet the needs of plant growth.
