Description

A kind of magnetic water keeping fertilizer for producing selenium rich kiwi fruit

Technical field

The present invention relates to technical field of fertilizers, more particularly to a kind of magnetic water keeping fertilizer for producing selenium rich kiwi fruit.

Background technology

Kiwi berry soft texture, sweet mouthfeel is organic containing actinidine, proteolytic enzyme, tannin pectin and carbohydrate etc. Thing, and the trace element such as calcium, potassium, selenium, zinc, germanium and 17 kinds of amino acid of needed by human body, are that a kind of quality is fresh and tender, nutritious, The delicious fruit of local flavor, has important effect to keeping health.Kiwi berry is a kind of berries vine fruit, and root is meat Matter root, growth is vigorous, with luxuriant foliage and spreading branches in leafy profusion, as a result more early, and substantial amounts of nutrient is consumed every year, and available nutrient is difficult to completely in soil Sufficient its demand, therefore its uptake characters is accurately grasped, growth of the nutrient to Kiwi berry is most important needed for supplement in time.At this stage Kiwi berry applies fertilizer based on quick-acting fertilizer, although Kiwi berry yield is greatly improved, but quick-acting fertilizer plant recovery of nutrient is low Under, soil hardening is easily caused, the pollution of the eutrophication and underground water of surface water also results in the urgency of kiwifruit fruit quality Play declines.

Soil moisture content plays an important role to Kiwi growth, while it is larger to be affected by the external environment, soil moisture content transformation Depending on soil moisture balance of payment position, and soil aperture is the important channel that soil moisture is exchanged, and is had very to soil water regime Big influence.Soil aperture is that moisture and chemical substance are quick, migration is mainly possibly even unique passage at a distance.In solution The soil water and solute can not occur sufficiently to interact with soil matrix when flowing through hole, and the direct quick penetration soil body enters ground , that is, there is priority migration in lower water.Water-keeping material can substantially change soil granular structure, increase soil porosity, reduce soil Unit weight, improves Infiltration speed, increases saturated hydraulic conductivity, protects retaining point, reduces evaporation, effectively improves precipitation, utilization of pouring water Efficiency.

In recent years, the development of activated carbon turn into domestic and international study hotspot, activated carbon because have specific surface area greatly, pore structure Flourishing, chemical property is stablized and the features such as high adsorption capacity relatively, is used in every field.And magnetic active carbon be then by Magnetization thing is introduced on activated carbon, is made it not only maintain the original functional group of carbon material but also is had the functional group of ferriferous oxide, so that Activated carbon surface electronegativity is enhanced, the heavy metal that can be allowed in fertilizer preparation and existed with cationic form in soil is applied Ion is mutually adsorbed by electrostatic interaction, while being imitated by the passivation that the electric microfield effect that itself magnetizes thing strengthens heavy metal Really, harm of the heavy metal-polluted soil to plant is greatly reduced.

Based on this, the present inventor by magnetic active carbon and polyacrylic acid potassium as water-keeping material research, by two The synergistic function of person, there is provided a kind of magnetic water keeping fertilizer of functional form on the basis of the nutrient demand for Kiwi berry.

The content of the invention

The object of the invention is exactly to make up the defect of prior art, there is provided a kind of magnetic water conservation for producing selenium rich kiwi fruit Fertilizer.

The present invention is achieved by the following technical solutions：

A kind of magnetic water keeping fertilizer for producing selenium rich kiwi fruit, is made from the following raw materials in parts by weight：Selenium yeast 2-4, dry rabbit excrement Powder 58-60, tea bran 33-35, degranulation corn ear 20-22, borax 1-2, sodium metasilicate 0.8-1.2, sodium humate 3-4, potassium carbonate 1- 2nd, potassium selenite 0.2-0.3, polyacrylic acid potassium 0.1-0.2, fresh tangerine leaf 40-44, zinc chloride 0.3-0.4, ferric sulfate 0.8- 1.0th, green vitriol 0.4-0.5,10% sodium dodecyl sulfate solution 2-4, appropriate amount of water.

The magnetic water keeping fertilizer preparation method of described production selenium rich kiwi fruit is comprised the following steps that：

（1）By retting compost fermentation 3-4 weeks in selenium yeast, dry rabbit excrement powder, tea bran mixing input fermentation vat, manually turned over during fermentation Heap 2-3 times, fermentation material is collected after the completion of waiting to ferment, and 40-50 mesh sieves were crushed after being baked to, and obtains fermentation material dry powder standby；

（2）To be placed in the water for decupling its quality after fresh tangerine leaf break into slag, add zinc chloride and stir post activation 2-3 hours, it is added thereto to ferric sulfate and green vitriol again afterwards, and it is molten that 10% dodecyl sodium sulfate is added dropwise simultaneously Liquid, stirring adjusts pH value of solution to 6.0-6.5 after 5-6 minutes with alkali lye, 35-40 minutes is stood after stirring, afterwards by solution Dried after suction filtration, be placed in being warming up to 400-420 DEG C in calcining furnace and calcine 80-90 minutes, taking-up is cleaned with water after the completion of calcining To neutrality, then dry prepared magnetic active carbon；

（3）Pass through granulator granulation after step 1 gained fermentation material dry powder and step 2 gained magnetic active carbon are mixed；

（4）Taken out after degranulation corn ear is calcined 45-60 minutes at 330-350 DEG C, dried at 70-75 DEG C after washing It is dry, then fully mixed with polyacrylic acid potassium, during compound put into agitator, then borax, sodium metasilicate are added thereto to, will stir Device rotating speed is controlled at 80-100 revs/min, is persistently stirred 60-70 minutes, must coat material standby；

（5）By step 4 gained cladding material particle exterior surface as obtained by rotary drum fluid-bed technique is evenly coated at step 3, Finally coated particle mix mixing with sodium humate, potassium carbonate, potassium selenite, obtain final product fertilizer of the present invention.

It is an advantage of the invention that：

The use that the present invention passes through magnetic active carbon, overcomes heavy metal in soil and remains by Electrostatic Absorption and magnetic field effect, Cause the problem of influence plant growth, while using the multi-pore structure of magnetic active carbon as fertilizer inner core, using polyacrylic acid Potassium etc. carries out the collaboration cladding of outer layer, fertilizer there was only Partial Fragment in its outer layer polymer chain after molten water in soil by soil Granular absorption, and during other long-chains then appear in the soil liquid in the form of the ring long and tail chain, these long-chains can live with magnetic Property charcoal complete bridge joint well, make connections between soil particle occupy larger space, so as to increase soil aperture so that native Earth is strengthened the sorptive power of hydrone, increases soil moisture content.

Fertilizer of the present invention using selenium yeast and potassium selenite as selenium source, by Organic Selenium and inorganic selenium two ways in fertilizer Middle addition, and using the release for coating extension selenium for calcining powdered carbon and sodium metasilicate etc. of corn ear, it is higher by sodium humate Load capacity Absorptive complex wave selenium, so as to realize long-term, effective intake of the kiwi fruit plant root system to selenium, for production selenium-rich macaque Peach provides good technical support.
