Description
Technical field
The present invention relates to the chemical fertilizer field in agricultural technology field, relate to a kind of particle phosphorus ammonium and
Preparation method, particularly relates to a kind of have quick-acting and long-acting sulfur and the particle phosphorus ammonium of zinc and preparation method.
Background technology
In plant growing process, can occur that yield drops in default of certain or certain several nutrient
The phenomenon that low, quality declines, wherein a lack of sulfur, zinc deficiency are the most universal.Its battalion during crop a lack of sulfur
Support and all can be affected with reproductive growth, owing to sulfur mobility in plant is less, therefore, children
Bud or young leaflet tablet first move back green and turn yellow, lobus cardiacus chlorosis yellow, cane is thin and delicate, root system length and regardless of
Branch, result of becoming civilized extends, and fruit reduces.Wherein the crop to sulfur sensitive is Cruciferae such as Brassica campestris L etc.,
Next to that pulse family, Nicotiana tabacum L., Cotton Gossypii, grass needs sulfur less；The common feature of crop zinc deficiency is:
Mesophyll chlorosis, shortened internodes, bunch life, lobule, plant is short and small, and growth is suppressed, and causes " stiff
Seedling ", " grey Seedling ", the physiological disturbance such as " fruitlet ", the empty flat rate of seed, fruit is high, yields poorly.
The wherein Fructus Mali pumilae in fruit and vegerable, Citrus, Fructus Persicae, Fructus Citri Limoniae, Semen Maydis, Oryza sativa L. and the dish in field crop
Bean, Caulis et Folium Lini and Flos lupuli (Flos Humuli Lupuli) etc. are sensitive to zinc；Secondly Rhizoma Solani tuber osi, Fructus Lycopersici esculenti, Bulbus Allii Cepae, Radix Betae, Herba Medicaginis and
Herba Trifolii Pratentis is more sensitive to zinc；Insensitive crop is Herba bromi japonici, Fructus Hordei Vulgaris, Semen Tritici aestivi and graminous pasture etc.；Right
Crop mends sulfur, zinc supplement, sulfur, the interaction of zinc, can improve the plant absorption to nutrient, can promote
Enter crop growth, improve setting percentage, strengthen cold-resistant, the resistance against diseases of crop, improve yield,
Improve quality of agricultural product.
Sulfur fertilizer, using of zinc fertilizer typically have two ways: one is soil application, and two is foliage-spray.Two
The nutrients ratio that kind method of application is absorbed has very big difference.The nutrient that soil application provides about accounts for
More than 70%.Foliage-spray is main because by the factor shadow such as condition, equipment in China's small peasant economy
Ring, large-area applications relative difficult.Therefore soil application is that crop mends sulfur, the major way of zinc supplement.
The traditional sulfur fertilizer being manured into soil, zinc fertilizer, wherein sulfur fertilizer is mainly with the sulfur such as ammonium sulfate, potassium sulfate
Hydrochlorate is main, and the mode such as it is easily leached after being manured into soil, runoff runs off thus causes under utilization rate
Fall.And zinc fertilizer is mostly based on zinc sulfate, zinc ion therein may be by following several reasons
Impact, and make the effectiveness of zinc reduce: the soil that pH value is higher is (such as Calx such as northern calcium soil, cinnamon soil
Property soil), soil itself contain substantial amounts of C03 2～、HC03～、PO4 2～Plasma, the zinc in soil from
Son is easily fixed to form the form being difficult to utilization absorbed by crops；The phosphorus more rich soil of element, in soil
Zinc ion easily interacts with phosphate radical again, forms the zinc phosphate of relatively stable states.Above-mentioned factor meeting
Sulfur, the effectiveness of zinc or utilization rate is made to reduce, it is difficult to meet the demand of the crop many nutrients of whole period of duration.
Improve the sulfur in crop whole growth promoter period, Zinc nutrition, be to make crop obtain high yield and excellent
The guarantee of matter.But current existing sulfur fertilizer, zinc fertilizer kind, be difficult to accomplish that quick-acting is held concurrently with long-lasting
Turn round and look at.Long-acting nutrient is dissolved slowly, it is difficult to meet the plant growth early stage demand to element nutrition；And it is quick-acting
Nutrient, early stage element nutrition supply is sufficient, but to the plant growth later stage again it is difficult to ensure that.
Accordingly, it is desirable to provide it is a kind of with quick-acting and long-acting sulfur, the particle phosphorus ammonium of zinc and preparation side thereof
Method solves the problems referred to above.
Summary of the invention
The purpose of the present invention is in order to solve the problems referred to above, it is provided that a kind of have quick-acting and long-acting sulfur and zinc
Particle phosphorus ammonium and preparation method, sulfur in the phosphorus ammonium of the present invention, zinc nutrient are with quick-acting and long-acting spy
Property；Product phosphorus ammonium is graininess, particle diameter 2～4 millimeters, with the granulated fertilizer size such as carbamide, compound fertilizer
Unanimously, convenient ginseng is mixed uses；Quick-acting and long-acting sulfur, zinc can meet in the whole period of duration of crop to sulfur,
Zinc demand, after using, both can alleviate crop a lack of sulfur, zinc deficiency symptom in time, again can the long period pair
Crop provides 3～7 months zinc elements, 6～12 months Sulfurs；Improve quality of agricultural product, strengthen and make
The diseases and insect pests resistance of thing, can be greatly improved crop yield.
A kind of particle phosphorus ammonium with quick-acting and long-acting sulfur and zinc, it is characterised in that described particle phosphorus ammonium
Including following components: 60～90 mass parts powder ammonium phosphates；4～the 10 long-acting sulfur of mass parts；5～20 mass
The quick-acting sulfur of part；The long-acting zinc of 1～10 mass parts；The quick-acting zinc of 1～20 mass parts；0～20 mass
The filler of part；The binding agent of 0～5 mass parts.
Described powder ammonium phosphate is the mixing of one or both any ratios in MAP, Diammonium phosphate (DAP)
Thing, its fineness is at 20～200 mesh.
Described long-acting sulfur is sulfur simple substance, described quick-acting sulfur be calcium sulfate, magnesium sulfate, ammonium sulfate,
Mixture more than one or both in iron sulfate, copper sulfate, manganese sulfate, zinc sulfate.
Described long-acting zinc is zinc oxide, in described quick-acting zinc zinc sulfate, zinc chloride, zinc nitrate
Mixture more than one or both.
Described zinc sulfate is zinc sulfate monohydrate, zinc sulphate heptahydrate or anhydro-zinc sulfate.
Described filler is the mixture of more than the one or both in Kaolin, bentonite, Pulvis Talci
Several.
Described binding agent is the mixed of any ratio of a kind of in aqueous solution of urea, binding agent liquid or two kinds
Compound, the percentage ratio of the quality of binding agent is 0.2～0.8%.
A kind of preparation method of the particle phosphorus ammonium with quick-acting and long-acting sulfur and zinc, it is characterised in that include with
Lower step: first above-mentioned each raw material is taken powder ammonium phosphate, long-acting sulfur, quick-acting sulfur, long-acting zinc, speed in proportion
Effect zinc, filler are pulverized and mixed, then are placed in pelletize in comminutor, drying, obtain having quick-acting and length
Effect sulfur and the particle phosphorus ammonium of zinc.
Described comminutor is granulating disc or Squeezinggranulator.
When using granulating disc, in granulating disc, spray binding agent in proportion, prepared
The particle diameter of phosphorus ammonium granule is 2～4 millimeters.
The particle phosphorus ammonium of the present invention, has a characteristic that
1, with quick-acting and long-acting feature.After using, both can alleviate crop a lack of sulfur in time, lack
Zinc symptom, can provide zinc element (3～7 months), thionin (6～12 each moon) to crop again the long period
Nutrition；
2, granule is uniform, particle diameter 2～4 millimeters, in the same size with the granulated fertilizer such as carbamide, compound fertilizer,
Convenient ginseng is mixed to be used；
