Abstract
The invention belongs to the crops field, and concretely relates to a duplex controlled-release fertilizer used for alkaline soil and a preparation method thereof. The controlled-release fertilizer is prepared by thermosetting resin, ferrous sulphate, sulphur, microcrystalline wax, urea, pure nitrogen, phosphoric pentoxide, potassium oxide and an adhesive. The controlled-release fertilizer comprises the following components by mass percentage: 12-12.75% of ferrous sulphate, 1.7% of sulphur, 0.2% of microcrystalline wax, 8.1% of urea, 15% of purity nitrogen, 15% of phosphoric pentoxide, 15% of potassium oxide, 0.8-1.2% of adhesive and balance of thermosetting resin. According to the invention, contradiction between quick result and long-acting performance can be solved. A lot of plants germinate in spring, a lot of nitrogenous fertilizer is required for nutrition growth, sulfur-coated urea can rapidly supply nitrogenous fertilizer, nitrogen supply amount is consistent with plant demand amount; at an anaphase of plant growth, after blooming and setting, a lot of phosphor and potassium elements are required, at the moment, phosphorus potassium fertilizer is released for satisfying the anaphase requirement.
Description
Technical field
The invention belongs to agricultural fertilizer technical field, be specifically related to duplexing Controlled Release Fertilizer of a kind of alkaline soil use and preparation method thereof.
Background technology
In soil, exist various chemistry and biochemical reaction, show different acidity or alkaline.In alkaline soils, titanium pigment is easily combined with calcium, generates insoluble phosphorus calcium salt class, reduces the validity of phosphorus; The validity of the element supplies such as while Iron in Soil, zinc, molybdenum, manganese, boron also reduces greatly, cause crop alimentary element bad, and generation lacks phosphorus, iron deficiency, scarce zinc, lacks the various physiological disturbances such as molybdenum, manganese deficiency, boron deficiency, damage to crops growth and production.
Soil ph depends primarily on the number of acid-base material in soil.Acidic substance derive from the mineral acid of the carbonic acid of the water-soluble formation of carbonic acid gas and the organic acid of organic matter decomposition generation and oxygenizement generation, the acidic substance that also have fertilising to add; Alkaline matter is mainly derived from the salts such as sodium carbonate in soil, sodium bicarbonate, calcium carbonate.Due to the difference of the southern and northern weather of China, south is moistening rainy, and it is acid that soil is more, northern drought, and soil is alkalescence more.
Controlled Release Fertilizer is by modes such as coating, parcel, interpolation inhibitor, and the decomposition of fertilizer, time of releasing are extended, and is conducive to improve the utilization ratio of fertilizer nutrient, thereby reaches the object that extends fertilizer validity period, promotes agricultural produce.
Existing Controlled Release Fertilizer is mainly add and supplement from the supply aspect of soil macroelement, trace element.Most soil have no lack of multiple element in fact, especially has no lack of trace element, but reduces because surface soil alkalinity makes the validity of soil element supply.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, duplexing Controlled Release Fertilizer of a kind of alkaline soil use and preparation method thereof is provided, not only can regulate the pH value of alkaline soil, can also effectively extend fertilizer validity period, promote agricultural produce.
The technical solution used in the present invention is, the duplexing Controlled Release Fertilizer that a kind of alkaline soil uses, described Controlled Release Fertilizer is made up of thermosetting resin, ferrous sulfate, sulphur, Microcrystalline Wax, urea, purity nitrogen, Vanadium Pentoxide in FLAKES, potassium oxide and tackiness agent, and the mass percent of preparing the required each component of duplexing Controlled Release Fertilizer is respectively: ferrous sulfate 12-12.75%, sulphur 1.7%, Microcrystalline Wax 0.2%, urea 8.1%, purity nitrogen 15%, Vanadium Pentoxide in FLAKES 15%, potassium oxide 15%, tackiness agent 0.8-1.2%, surplus is thermosetting resin.
The preparation method of the duplexing Controlled Release Fertilizer that described alkaline soil uses, comprises the following steps:
Step 1, take each component by the mass percent of described each component;
Step 2, with thermosetting resin by ferrous sulfate coating, make component 1, for subsequent use;
Step 3, use sulphur coated urea, and with Microcrystalline Wax sealing, make component 2, for subsequent use;
Step 4, purity nitrogen, Vanadium Pentoxide in FLAKES and potassium oxide are mixed, and with thermohardening resin coated, make component 3, for subsequent use;
Step 5, will component 1, component 2, component 3 and tackiness agent stir after mixing, and after granulation, oven dry, cooling, sub-sieve, becomes particle, chooses the fertilizer that particle diameter is 2-3mm, makes duplexing Controlled Release Fertilizer.
Described tackiness agent is made up of starch, cyclodextrin poly vinyl alcohol, calcium oxide, Wild Chrysanthemum powder and carboxymethyl cellulose, and the parts by weight of preparing the required each component of tackiness agent are respectively: starch 20-25 part, cyclodextrin poly vinyl alcohol 20-30 part, calcium oxide 35-40 part, 8 parts of Wild Chrysanthemum powder 3-, carboxymethyl cellulose 17-22 part.
beneficial effect
One, in the present invention, be added with ferrous sulfate and can effectively solve detrimentally affect farm crop being brought due to iron deficiency, and the slow release of ferrous sulfate can continue the micro-acid environment that keeps soil favourable, be conducive to the lasting absorption of Plant To Nutrient, the temporary and plant that has solved ordinary method acid adjustment absorbs the grow contradiction of chronicity of rich water.
Two, in the present invention, quick-acting bag Thio Ureas combines with thermosetting resin composite fertilizer, the ferrous sulfate of slowly-releasing, has solved the contradiction between quick-acting and long-acting.Many plants germinate spring, need a large amount of nitrogenous fertilizer to nourish and grow, and bag Thio Urea can fast supply nitrogenous fertilizer, and the supply of nitrogen and plant demand reach unanimity; Sulphur also has the effect that reduces soil pH value simultaneously.In the plant-growth later stage, after flowering of plant is beared fruit, need a large amount of phosphorus, potassium element, and at this moment phosphorus potash fertilizer discharges, and meets later stage needs.
Three, the tackiness agent that the present invention contains Wild Chrysanthemum powder by interpolation, has promoted the service efficiency of Controlled Release Fertilizer greatly, effectively raises the output of farm crop.
Four, the present invention can effectively improve the validity of soil nutrient.The validity of Soil Phosphorus is obviously subject to the impact of acid-basicity, exceedes at 7.5 o'clock at soil pH value, and phosphoric acid and calcium or iron, aluminium form slow effect state, and validity is reduced, and calcium, magnesium solubleness in strong basicity soil is low, and validity reduces.The trace elements such as boron, manganese, copper, validity also reduces greatly in alkaline soils.In addition, contain more sodium carbonate in alkaline soil, this is to the toxic action of having made deposits yields, and the present invention, by regulating soil pH value, can obviously improve the validity of the soil nutrients such as calcium, magnesium, boron, manganese, copper, also can reduce the content of sodium carbonate simultaneously.
Five, the present invention is conducive to the optimum growth of soil, improves Soil structure.In alkaline soil, hydrogen and sodium are more, and calcium lacks, and are difficult to form good Soil structure, are unfavorable for plant growth.The present invention, by regulating soil pH value and adding calcium salt, is conducive to the optimum growth of soil, improves Soil structure.
Six, the present invention can improve utilization rate of fertilizer greatly, reduces Fertilizer application amount, reduces production costs, and improves productivity effect.Controlled Release Fertilizer of the present invention can improve the plant recovery of nutrient 50% of fertilizer to more than 100%, and therefore Fertilizer application amount can reduce half consumption, and has obvious effect of increasing production.Therefore use this invention, can effectively reduce production costs, additional income.
