Description

A kind of corn improves slow release fertilizer synergistic agent of soil ammonium content and preparation method thereof

Technical field

The present invention relates to a kind of fertilizer synergist technical field, particularly a kind of corn improves slow release fertilizer synergistic agent of soil ammonium content and preparation method thereof.

Background technology

Corn is a kind of important cash crop of China, and the output of the input of fertilizer to corn serves vital effect, but in the actual planting process of corn, long-term existence the problem of apply fertilizer single and excessive fertilization, the average utilization of fertilizer is very low, and its major cause is the quick-acting of fertilizer and volatile fugitive volatile.The measure that correspondence is taked is then use release-controlled coated fertilizer to improve the utilization ratio of nutrient, but individual layer bag film strength is low, and slowly-releasing nutrients ratio is fixed, and without specific aim, does not meet the development that the demand etc. of crop different times to nutrient constrains self.

Current inventor provides the fertilizer synergist that a kind of corn planting uses for this reason, coated by different three layers of slow release layer, the corresponding seedling stage of corn growth, vegetative period and three periods of ripening stage, collocation common fertilizer uses the regulation of fertilizer requirement that fully can meet corn, not only improve the utilising efficiency of fertilizer, reach fertilizer and need fertile balance, improveing the physico-chemical property of planting soil, for the stable high yield of corn provides sound assurance simultaneously.

Summary of the invention

The present invention compensate for the deficiencies in the prior art, provides a kind of corn to improve slow release fertilizer synergistic agent of soil ammonium content and preparation method thereof.

Technical scheme of the present invention is as follows:

Described slowly releasing trace element chelating layer is made up of the raw material of following weight part: attapulgite 24-26, discarded animal skin 16-18, ferrous sulfate 4-7, zinc sulfate 3-5; Its preparation method to calcine 2 hours at attapulgite is placed in 600-800 DEG C and to wear into fine powder for subsequent use, discarded animal skin is joined in 6-8mol/L hydrochloric acid and is hydrolyzed 18-24 hour, adding lime slurry neutralization again to PH7 filters, and adds ferrous sulfate, be heated to 40-60 DEG C in filtrate, chelating 1-2 hour, add zinc sulfate again, chelating 1.5-3 hour at 50-80 DEG C, attapulgite fine powder is joined in gained chelating liquid, drying is also pulverized, and obtains composite chelate powder.

Described slowly-releasing micritization ground phosphate rock coating layer is made up of the raw material of following weight part: ground phosphate rock 28-32, cow glue 8-10, water are appropriate; Its preparation method is adopted by ground phosphate rock vibration mill micronization to obtain micritization ground phosphate rock, then cow glue and micritization ground phosphate rock jointly to be dropped into etc. in quality water, soaks after 8-10 hour and mixed system is heated to 70-80 DEG C, stir.

The concrete steps of the preparation of described fertilizer synergist are as follows:

(1) tamarind ground-slag, wormcast, Tremoliteor Tremoliteasbestos powder mixed and are placed in compost pond, adding a small amount of water secondary fermentation 25-27 days, after gained tunning is dried pulverizing, granulation is for subsequent use;

(2) heating of slowly-releasing micritization ground phosphate rock coating layer is dissolved rear even application in step one gained particle exterior surface, form the internal layer of synergistic agent;

(3) by levigate after calcium superphosphate and potassium azide mixing, add after a small amount of water with step 2 gained particle mix and blend, drop in whizzer centrifugal 20 minutes with 60-80 rev/min again, slowly releasing trace element chelating layer is added again in whizzer, with 200 revs/min of centrifugal 8-10 minute, to form the middle level of synergistic agent, taking-up particle post-drying is for subsequent use;

(4) by calcium formiate and potassium selenite levigate after add a small amount of water even application in step 3 gained particle exterior surface, then slowly-releasing microbial layer and remaining component are mixed and add the spraying of a small amount of water and be wrapped in outside particle, form the skin of synergistic agent;

(5) air-dry with gas blower at step 4 gained particle being placed in 40-50 DEG C, weighing and bagging is placed on dry place and preserves.

The using method of synergistic agent of the present invention is be manured into soil after mixing according to the ratio of 8%-10% and common fertilizer.

Beneficial effect of the present invention:

Its adsorptive power to microorganism can be increased to diatomaceous modification in slowly-releasing microbial layer, stable in properties, extends working time simultaneously, and to soil and microorganism toxicological harmless effect, beneficial microorganism activity can improve joins nutrient availability in fertilise, increases the utilization ratio of fertilizer.

The stability of the high viscosity performance guarantee synergistic agent particle of cow glue by adding in slowly-releasing micritization ground phosphate rock coating layer, simultaneously when after the outer composition of layer release of synergistic agent, internal layer is met water and can progressively be decomposed, and improve sustained release performance, and the interpolation of micritization ground phosphate rock can to the NH of internal layer 4 +-N plays good slow releasing function, for the heavy demand of corn ripening stage to nutrient provides support.

Corn fertilizer synergist of the present invention, soil ammonium-state content is increased by the potassium azide of interpolation and the synergy of microorganism, conservative control nitrate nitrogen content, both the absorption of corn to nitrogen had been met, the loss of Nitrogen element can be reduced again, improve the utilization ratio of fertilizer, and reduce corn nitrite, improve the quality of corn.
