Abstract

The invention discloses a formula for an organic-inorganic special fertilizer for a walnut tree. According to the formula, 500 kg of bulk blending fertilizer is produced by stirring and blending 150 kg of urea, 100 kg of monoammonium phosphate, 75 kg of potassium chloride, 125 kg of an organic fertilizer and 50 kg of a calcium magnesium phosphate fertilizer. The produced organic-inorganic bulk blending fertilizer contains 39% of three elements (20% of nitrogen, 10% of phosphorus and 9% of potassium), at least 10% of microelements, and at least 10% of organic matter, amino acid and humic acid. Fertilizer sources in the formula are strongly facilitated mutually, that is, an adduct can be formed by blending monoammonium phosphate with urea, and slow-controlled release fertilizer with no need for coating treatment is formed after nutrients are gradually released; under the action of urease in the soil, urea is converted into ammonium hydroxide to react with monoammonium phosphate, and diammonium phosphate and water are generated after the reaction, so that the functions of water conservation and fertilizer efficiency improvement are realized. The organic-inorganic bulk blending fertilizer is applicable to the walnut tree.

Description

A kind of organic-inorganic walnut special fertilizer formula

Design field

The present invention relates to the chemical fertilizer field of fertilization compositions based on earth measurement.

Background technology

In producing at traditional agriculture, only reuse nitrogenous fertilizer, think little of phosphate fertilizer and potash fertilizer, more think little of the phenomenon that do not apply fertilizers scientifically of the trace elements such as calcium, magnesium, sulphur moderate-element and iron, zinc, manganese, boron, molybdenum, chlorine, copper, " research and development of highly effective and safe fertilizer are accelerated " and " deeply implementing the requirement of fertilization compositions based on earth measurement " in accordance with No.1 Central File in 2013, I stands according to the principle of balance fertilizing " law of cask ", work out containing big or middle, micro-all nutritive elements, organic matter, the organic-inorganic walnut special fertilizer formula that amino acid and humic acid all have.

Summary of the invention

The object of the invention is to the principle according to balance fertilizing " law of cask ", work out organic-inorganic walnut special fertilizer formula.

The present invention adopts following technical scheme: according to Production requirement, and select urea, monoammonium phosphate, Repone K, fertilizer and fused(calcium magnesium)phosphate five kinds of sources of manure, each source of manure characteristic is as follows: urea nitrogenous 46.4%; Monoammonium phosphate is nitrogenous 11%, phosphorus 44%; Repone K is containing potassium 50%; Fertilizer is nitrogenous 16%, potassium 2%; Fused(calcium magnesium)phosphate is containing Vanadium Pentoxide in FLAKES 18%, magnesium oxide 8% ~ 15%, calcium oxide 25% ~ 32%, silicon-dioxide 20% ~ 30%, ferric oxide 0.5% ~ 1.5%, manganese oxide 0.1% ~ 0.3% and a small amount of boron, zinc, copper, molybdenum, selenium, nickel, Deng the requisite trace element of plant growth, it is multi-elements composite fertilizer worthy of the name, very strong promoter action is had above between each source of manure, one ammonium fusion urea can form adducts, Releasing nutrient gradually; Under the effect of urase, convert ammonium hydroxide to after urea is manured into soil, react with monoammonium phosphate, generate diammonium phosphate and water, play fertilizer conservation water retention; The sources of manure such as calcium magnesium phosphorus powder blending urea, make its particle surface, form one deck calcium magnesium phosphorus powder film, both prevented finished product deliquescence caking phenomenon, and also can reduce the utilization of phosphorus fixation and slow-release nitrogen, this formula comprises big or middle, micro-all nutrients, market is rare, due in this formula, middle and trace element and organic matter, amino acid, humic acid are all without charge, so the Bulk Blending Fertilizer that this formula is produced has the advantages such as fertilizer efficiency is high, fertility is long, price is low, with strong points.

Embodiment

The invention discloses a kind of organic-inorganic walnut special fertilizer formula, often produce 1000 jin of Bulk Blending Fertilizer, with 300 jin, urea, monoammonium phosphate 200 jin, 150 jin, Repone K, fertilizer 250 jin, 100 jin, fused(calcium magnesium)phosphate, stir blending, be made into N P and K three elements 39% (20:10:9); Medium trace element >=10%, organic matter, amino acid and humic acid >=10%,

Concrete blending parameter sees following table:
