Abstract

The invention discloses an organic-inorganic watermelon special bulk blending fertilizer formula. According to the formula, an organic-inorganic watermelon special bulk blending fertilizer is scientifically prepared according to a balanced fertilization 'wooden barrel law' theory and a watermelon fertilizer requirement law; each 1000 kg of the organic-inorganic watermelon special fertilizer are produced by stirring and blending 4.3-4.7 parts of urea, 1.3-1.7 parts of monoammonium phosphate, 1.8-2.2 parts of potassium sulfate, 1.3-1.7 parts of an organic fertilizer and 0.3-0.7 part of calcium-magnesium-phosphate fertilizers, the proportion of three essential elements nitrogen, phosphorus and potassium is 24 to 7 to 10, the total nutrient is 41%, and the organic-inorganic watermelon special bulk blending fertilizer contains 4% of medium trace elements, 3% of organic matters, 1.5% of amino acid and 1.5% of humic acid; because the bulk blending fertilizer contains macro (nitrogen, phosphorus and potassium), medium (calcium, magnesium and sulfur), trace (copper, iron, manganese, boron, zinc, molybdenum and chloride) nutrients and has the organic matters, amino acid and humic acid, the bulk blending fertilizer has the advantages of low price, high fertilizer efficiency, strong pertinence and the like.

Description

A kind of organic-inorganic watermelon special blending fertilizer formula

Technical field

The present invention relates to inorganic and organic mixed fertilizer material research and development field.

Background technology

Modern age, some developed countries widely popularize BB fertilizer, so-called BB fertilizer is the abbreviation of English BulkBlendingFertilizer, namely be dry mixed with two or more granulated fertilizer and form, in Japan, radius 50 kilometers just has a fertilizer mixing station, a fertilizer mixing station is according to different soil fertility and crop regulation of fertilizer requirement, just there is more than 800 formula, China " 11. five " planning in, also using Formula fertilization by soil testing as key popularized project, and bulk blended fertilizer (BB is fertile) operative norm (GB21633-2008) has been put into effect in 2008, No.1 Central File in 2013, emphasize " accelerating the research and development of highly effective and safe fertilizer ", this year, No.1 Central File is emphasized again " supporting that concentrated fertilizer uses " and " lifting of the Expedite the application soil organism " work, our Henan Province just put into effect as far back as calendar year 2001 " formula fertilizer " provincial standard (DB41/T275-2001), the Ministry of Agriculture holds fertilization compositions based on earth measurement on-the-spot meeting in our Henan Province, can on play I head of a station Wu Luzhi researcher and write, science popularization Henan opera-" the fastening guarantor's new biography-formula fertilizer good " of being sung by three, Henan opera institute of Henan Province, obtain colleague's favorable comment, I stands existing 16 years histories of building a station, head of a station Wu Luzhi researcher, the first soil and fertilizer expert obtaining " professor " level academic title in basic unit in the whole nation, once repeatedly on the world and national soil and fertilizer meeting, academic exchange was carried out, and carried out Formula fertilization by soil testing lecture at the Chinese Central Television (CCTV) the 7th channel, the basic components of the monoammonium phosphate fusion urea production bulk blended fertilizer of his research and development, published by U.S.'s " agrochemical weekly ", " Farmers' Daily " reports his forerunner for the research and development of bulk blended fertilizer formula, under the new situation, he feels the R&D work of quickening highly effective and safe fertilizer deeply and is duty-bound, the formula of the safe bulk blended fertilizer of staple crops organic/inorganic high efficient is developed in plan in recent years.

Summary of the invention

The object of the invention is to: according to the principle of balance fertilizing " law of cask ", according to the fertilization rule of watermelon, develop organic-inorganic watermelon special blending fertilizer formula.

The present invention adopts following technical scheme:

Select urea, monoammonium phosphate, potassium sulfate, fertilizer and fused(calcium magnesium)phosphate five kinds of sources of manure, each source of manure characteristic is as follows: urea nitrogenous 46.3%; Monoammonium phosphate is nitrogenous 11%, phosphorus 44%; Potassium sulfate is containing potassium 50%; Fertilizer is nitrogenous 16%, potassium more than 2%, organic 20%, amino acid/11 0%, humic acid 10%, sulphur 10%, also containing a small amount of magnesium, boron, zinc, iron, etc. trace element; 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%, also containing trace and beneficial elements such as a small amount of boron, copper, zinc, molybdenum, nickel, very strong Lian Yingxing is had between each source of manure, monoammonium phosphate fusion urea can form high polymer, Releasing nutrient gradually in soil, forms the slow-release fertilizer without Cotton seeds; Urea blending acid phosphatase one ammonium and potassium sulfate, can delay the decomposition of urase to urea, and the ammonium hydroxide that urea converts in soil and monoammonium phosphate react, generate diammonium phosphate and water, all play the effect of preserve moisture and fertility, in addition, calcium magnesium phosphorus powder for the production of, urea can be made, monoammonium phosphate, potassium sulfate, organic fertilizer particles top layer forms one deck book film, reach this Bulk Blending Fertilizer not deliquescence, non-caking object.

Embodiment

According to the principle of balance fertilizing " law of cask ", according to the regulation of fertilizer requirement of watermelon, science is formulated, often prepare 1 ton of organic-inorganic fertilizer special for watermelon, need 4.3 ~ 4.7 parts, urea, monoammonium phosphate 1.3 ~ 1.7 parts, potassium sulfate 1.8 ~ 2.2 parts, fertilizer 1.3 ~ 1.7 parts, 0.3 ~ 0.7 part, fused(calcium magnesium)phosphate, stir blending, be made into N P and K three elements 24: 7: 10, total nutrient is 41%, medium trace element 4%; The organic-inorganic watermelon mixing fertilizer specially of organic matter 3%, amino acid/11 .5%, humic acid 1.5%; Due to this formula include greatly (nitrogen, phosphorus, potassium), in (calcium, magnesium, sulphur), micro-(copper, iron, manganese, boron, zinc, molybdenum, chlorine) all nutrients; Organic matter, amino acid, humic acid has entirely, has price low, the advantages such as fertilizer efficiency is high, with strong points.

Concrete blending parameter sees following table:
