Description

A kind of long-acting special compound (mixing) fertilizer

The present invention relates to a kind of long-acting special compound (mixing) fertilizer

In the prior art, all relate to the fertilizer that utilizes macronutrient and micronutrient element to make, on agricultural, all obtained certain effect, but its efficient is all lower as ZL90105249, ZL88101637, ZL90105116 etc.CN1086507A provides a kind of full-elementary fertilizer that comprises a large amount of, middle amount and micronutrient element of stable no antagonistic action, the better action of also having sent out brightness on agricultural.But it is shorter that above-mentioned fertilizer in use all belongs to fertilizer efficiency period, do not satisfy crop time of infertility to nutrient demand, also must topdress again.ZL96119508.8 relates to long-acting specific composite fertilizer, and the fertile phase can reach 100-150 days, and nitrogen utilization efficiency improves 15-20%, has also solved the difficult problem that plastic mulched crop inconvenience is topdressed simultaneously.Yet, various crop long-acting specific composite fertilizers are by adding single nitrogen fertilizer potentiating agent urease inhibitor hydroquinone (Resorcinol) as the cotton long-acting specific composite fertilizer, or nitrification inhibitor (Dyhard RU 100) prolongs fertilizer efficiency period and improves utilization rate of nitrogen fertilizer as the corn long-acting specific composite fertilizer.But in composite fertilizer, all can't make fertilizer efficiency period, output reach best effect by single synergistic agent.The present invention be directed to existing problem, go out a kind of long-acting special compound (mixing) fertilizer through a large amount of development tests.

The object of the invention is that a kind of long-acting special of developing compound (mixing) fertilizer comprises: nitrogen, phosphorus, potassium, zinc, boron, manganese, molybdenum, iron, calcium, sulphur and effect-elongating agent for nitrogen fertilizer; Its making method adopts conventional " granulating method " or " slurry process ".The fertilizer efficiency period of this composite fertilizer can reach 110-160 days, and utilization rate of fertilizer improves more than 20%, cotton, food crop volume increase 15-20%, and other is as volume increase 30-40% such as beet, vegetables, and equal yield level can be saved chemical fertilizer 20%.Fertile process of confession that simultaneously should fertilizer and the regulation of fertilizer requirement of crop match, can better satisfy the crop nutritional needs in the time of infertility, only do once base fertilising, no longer topdress, reach volume increase, increase income, save net effects such as fertilizer, saving of labor, thereby solved the problem that the plastic mulched crop difficulty is topdressed.

A kind of long-acting special of the present invention composite fertilizer comprises in this long-acting special composite fertilizer: nitrogen, phosphorus, potassium, zinc, boron, manganese, molybdenum, iron, calcium, sulphur and nitrogen fertilizer potentiating agent; Wherein:

Nitrogen is urea, ammonium phosphate, sell ammonium, bicarbonate of ammonia, ammonium sulfate;

Phosphorus is calcium superphosphate, double superhosphate, diammonium phosphate, monoammonium phosphate, fused(calcium magnesium)phosphate;

Potassium is Repone K, vitriolate of tartar, potassic-magnesian fertilizer;

Zinc is Zinc vitriol, zinc chloride;

Boron is borax, boric acid;

Manganese is five anhydrous manganeses, four hydration Manganous chloride tetrahydrates;

Molybdenum is ammonium molybdate, Sodium orthomolybdate;

Iron is ferrous sulfate;

Calcium is calcium superphosphate, three material;

Sulphur is vitriolate of tartar;

Sustained release drug is Resorcinol, Dyhard RU 100; The each component proportioning is (weight percent): nitrogen 18-30%, phosphorus 8-20%, potassium 2-10%, zinc 0.1-0.5%, boron 0.01-0.3%, manganese 0.01-0.8%, molybdenum 0-0.2%, iron 0-0.4%, calcium 0-0.4%, sulphur 0-5%, Resorcinol 0-4%, Dyhard RU 100 0-1.2%.

A kind of long-acting special of the present invention composite fertilizer, quinhydrones in this fertilizer is a urease inhibitor, be added to the effect that can suppress urase after being manured into soil in the composite fertilizer, the speed that makes nitrogen be hydrolyzed into ammonia-state nitrogen is slowly carried out, the too fast accumulation volatilization loss that has reduced ammonia with become NH ₄ ⁺And run off.But quinhydrones can not suppress too much ammonia-state nitrogen is hydrolyzed into the leaching of nitric nitrogen and the loss that denitrification causes nitrogen in the soil by the effect of nitrate reductase.Yet, add two cyanogen ammoniums and just can reach this purpose.Because Dyhard RU 100 is a nitrate reductase inhibitor, the reaction that can make ammonia-state nitrogen in the soil be converted into nitric nitrogen is interrupted or is slowed down.Itself is again a kind of slow nitrogenous fertilizer simultaneously, generates urea with the water reaction.Therefore the present invention adds quinhydrones and Dyhard RU 100 simultaneously, can not only make fertilizer efficiency period reach the need of crop, and can improve its chemical fertilizer utilization ratio greatly, increases output, improves chemical fertilizer to underground contaminated water source.
