Description
Technical field
The present invention relates to technical field of agriculture science, more particularly, to a kind of manufacturing method of rounded grain zinc boron potassic fertilizer.
Background technology
Potassium is the important nutrient needed for plant growth, and potassium can promote the growth of plant stalk, enhance plant cold-resistant energy
Power improves fruit quality.Potassium is generally processed into nitrogen, phosphorus, K composite fertilizer together with nitrogen, phosphorus etc., for agricultural use.With country
Popularization to fertilization compositions based on earth measurement, Blending Fertilizer because its formula flexibly, be easy to mechanized application and obtain market accreditation, rounded grain
The potash fertilizer of shape also comes into being.Chinese patent CN201310528939.0, CN 201410063225.1 individually discloses rounded grain
The manufacturing method of potash fertilizer.The appearance of rounded grain potash fertilizer will cause Blending Fertilizer, soil testing and fertilizer recommendation to become more convenient,
Necessary to trace element is plant and animal normal growth and lives, it is known as " essential trace element " or " micro-
Measure nutrient ", usually referred to as " trace element ".Essential trace element has very strong specificity in the in vivo effect of plant and animal,
Can not lack with it is irreplaceable, when supply deficiency when, plant often shows specifically to lack symptom, crop yield drop
Low, quality declines, and may have no harvest when serious.Apply trace-element fertilizer, be conducive to improve the yield and quality of crop.
Zinc, boron be plant growth must trace element, soil zinc deficiency, rice anisopliae root decline, the grey seedling of corn；Specific aim
Shi Xin, boron fertilizer, crop yield are extremely notable.Compared with macroelement fertilizer, trace-element fertilizer is that amount of application is few, nutrient cost
Height, there are micronutrient is uneven, the too fast problems low with plant recovery of nutrient of nutrients release in application, shadow
The performance of micro- effect is rung.
The content of the invention
The purpose of the present invention is adding in trace element zinc, boron on the basis of rounded grain potash fertilizer, fertilizer is further improved
Nutritive value.Trace element is creatively built in inside granular potash fertilizer by the present invention, and will be partly micro- with slow
The mode for releasing coating adds in fertilizer surface, has well solved that micronutrient is uneven, nutrients release is too fast and nutrient is sharp
With rate it is low the problem of.A kind of rounded grain zinc boron potassic fertilizer, the particle has been made by way of interior addition and outer wrapping in the present invention
Potash fertilizer K2O content is 40%-47%, Zn content 1%-2%, Boron contents are that 0.1%-0.5% should.In the table of rounded grain potash fertilizer
Bread wraps up in one layer of degradable controlled release material containing zinc, boron nutrition element, obtains the zinc boron potash fertilizer with sustained release performance.
The present invention uses following technical scheme：
A kind of manufacturing method of rounded grain zinc boron potassic fertilizer, it is characterised in that：In granulation process, by zinc sulfate, boric acid

47%th, the rounded grain potash fertilizer that Zn content 1%-2%, Boron contents are 0.1%-0.5%.Then on the surface of the rounded grain potash fertilizer
One layer of degradable controlled release material containing zinc, boron is wrapped up, obtains the rounded grain zinc boron potassic fertilizer of tool sustained release performance.
The zinc sulfate is zinc sulfate, monohydrate zinc sulphate or white vitriol.
The Boratex is Boratex, five water Boratexes or ten water Boratexes.
The additive amount of the degradable controlled release material is the 0.5%-3% of rounded grain potash fertilizer.
The auxiliary material is the nonmetallic minerals such as bentonite or attapulgite.
The degradable controlled release material preparation method is：Each substance dosage by weight percentage, adds in seaweed in water
Sodium alginate soln, wherein sodium alginate dosage 10% is made in sour sodium, then sodium alginate soln add in 40% zinc sulfate,
30% sulfuric acid boron, the complexing agent of 0.1-1% form the degradable release-controlled material containing trace element zinc and boron through complex reaction
Material, complexing agent is ethylenediamine tetraacetic methene sodium phosphate (EDTMPS), diethylene triamine pentamethylene phosphonic salt (DETPMPS), amine front three
Pitch the mixture of one or more of phosphate.
Obtained rounded grain zinc boron potassic fertilizer, containing micronutrient boron, zinc, micro- nutrients release has quick-acting
With the double effects of sustained release, sustained release boron, the nutrients release cycle of zinc are 10-30 days.
The present invention has the advantages that following prominent：
