Description
Technical field
The present invention relates to a kind of fertilizer, specially a kind of fruit-specific fertilizer and preparation method thereof.
Background technology
Fruit contains abundant vitamin, mineral matter and fructose, and in daily life, people often eat some fruit to supplement the nutrition of needed by human body, ensure the health of human body, food ingestion is big, lays equal stress in human diet mechanism with grain, vegetables, and its yield and cultivated area have obvious ascendant trend.Economy of the fruit tree benefit depends on the yield and production cost of fruit tree, and the high-quality of fruit is even more the target of the unremitting pursuit of people, effectively using limited land resource, improves the yield of fruit tree crop and fruit quality is direction that people make great efforts.But in planting fruit trees, due to the fertility deficiency of planting soil, pest and disease damage is serious, and a large amount of agricultural chemicals are commonly used in orchard worker, causes in planting soil and fruit surface forms substantial amounts of residues of pesticides so that human safety receives threat.
The growth of fruit tree is as other crops, it is necessary to using npk fertilizer, it is also necessary to rich in many mineral matters such as calcium, iron, sulphur, zinc and trace element.Need the nitrogen that absorbs in the majority in its growth course, nitrogenous fertilizer is to improving output of the fruit tree positive effect.Urea is nitrogenous high-quality nitrogenous fertilizer high, fertilizer efficiency is fast, dosage is big.But in use, it is lost in easily by approach such as volatilization, leaching, decomposition and runoff urea, causes fertilizer efficiency utilization rate not high, this not only causes the waste of chemical fertilizer, and is polluted for environment for the survival of mankind such as air, water body soil.Potash fertilizer：Potassium is the essential a great number of elements of plant growth, and the essential element of Peng fruit and shape fruit.
In order to solve the above-mentioned technical problem, at present, it is more both at home and abroad that coating processing is carried out to urea using sulphur and various macromolecule resins.Or uric acid inhibitor and nitrification inhibitor are added, using the high molecular polymers such as cyclochloride resin, acrylic resin are material coated or even multilayer coating or several include fertiliser granulates mixing etc. and form sustained-release and controlled release fertilizer.Existing special fertilizer for fruit trees has the following disadvantages：Multilayer coating, complex manufacturing, investment is big, production cost is high and coating layer is difficult to degrade, and long-term use can be negatively affected to soil.Main nutrient elements proportioning in fertilizer mismatches for fruit tree growth demand, and fertilizer efficiency utilization rate is low.
The content of the invention
To avoid above-mentioned deficiency, the present invention is intended to provide a kind of nutrition is comprehensive, sustained release performance is excellent, can fully meet that fruit tree to nutrient demand, plays fruit-specific fertilizer of effect of fertilizer and preparation method thereof to greatest extent.
To achieve the above object, the present invention uses following technical scheme：A kind of fruit-specific fertilizer, including granular compound fertilizer and coating layer, granular compound fertilizer raw material composition and parts by weight are：45~50 parts of urea, 6~10 parts of potassium chloride, potassium sulfate 6~10, blend 35~40 parts.

A kind of preparation method of fruit-specific fertilizer, comprises the following steps：
A, the synthesis of coating feed liquid：Coating with ground phosphate rock after according to the accurate metering of formula it is standby, rosin is put into fusion tank, is heated to molten condition.
B, it is granulated：Potassium chloride, magnesium sulfate, zinc sulfate, calcium carbonate and ammonium nitrogen are thrown in agitator; it is sufficiently stirred, is granulated after mixing using fertilizer granulator, is granulated and sprays tung oil simultaneously; particle diameter is obtained after drying, cooling and is 0.5~10mm compound fertilizer a, and compound fertilizer a is delivered in coating machine；
Potassium sulfate, nitrate nitrogen and boric acid are thrown in agitator, are sufficiently stirred, is granulated after mixing using fertilizer granulator, is granulated and sprays tung oil simultaneously, compound fertilizer b is obtained after drying, cooling.
C, coating：Compound fertilizer a and granular urea, Diammonium phosphate (DAP) prepared by step B is added in the encapsulation tool of rotation, the rosin of spraying step A meltings, fertiliser granulates and liquid coating agent turn to fertiliser granulates surface in encapsulation tool container and form one layer of adhering liquid, superfine phosphorite powder is added in the encapsulation tool of rotation, superfine phosphorite powder is turned to and is coated on fertiliser granulates surface.
D, drying：Fertilizer after coating is sent into dryer and dries cover half, heated-air drying, room temperature cooling.
The present invention has advantages below：①Fertilizer of the present invention uses controlled-release technology, can accomplish single-dose application, lasting to support, and does not waste early stage, later stage not de- fertilizer.Controlled Release Nitrogen Fertilizer has controllable dissolution rate, and different according to crop is applied, dissolution time is controlled at 28 days to 120 days, and utilization rate of fertilizer is improved significantly, and increase rate is 30% -70%.
2. the invention provides a kind of nutrition is comprehensive, sustained release performance is excellent, can fully meet the needs of fruit tree is to nutrient, play the effect of fertilizer to greatest extent, output of the fruit tree and can be improved and improve its quality, be suitable for the slow-release fertilizer of planting fruit trees administration.
3. the present invention is using ground phosphate rock as parcel main material, rosin as coating agent, ground phosphate rock can in soil natural degradation, avoid causing secondary pollution and soil hardening, phosphorus contained by ground phosphate rock is made for thing in the presence of soil and crop root, by slow release and absorbed.
4. the main nutrient elements reasonable mixture ratio in fertilizer, the nitrogen in composition of raw materials is added in the form of Controlled Release Fertilizer, and large percentage, provides nutrient for fruit tree, fertilizer efficiency utilization rate is high.
5. the present invention is with micro- fertilizer（Boron and Zn-ef ficiency）, worked in fruiting period.
