CN104671918A - Special blended fertilizer formula for sweet potatoes - Google Patents

Abstract

The invention discloses a special blended fertilizer formula for sweet potatoes. 1000kg of the blended fertilizer is prepared to the special blended fertilizer for efficiently and safely producing cotton by stirring and blending 300kg of urea, 200kg of monoammonium phosphate, 250kg of potassium sulphate, 150kg of organic fertilizers and 100kg of a calcium magnesium phosphate fertilizer, wherein the special blended fertilizer for efficiently and safely producing sweet potatoes comprises 40% of nitrogen phosphorus and potassium in a ratio of 18: 10: 12, 8% of medium and trace elements, and 6% of organic matters, amino acids and humic acid. As the formula contains macro, medium and trace elements, organic matters, amino acids and humic acid, the special blended fertilizer has the advantages of efficiency, safety, low price, strong pertinence and the like.

Description

A kind of highly effective and safe sweet potato special blending fertilizer formula

Design field

The present invention relates to highly effective and safe bulk blended fertilizer research and development field.

Background technology

Modern age, some developed countries widely popularize BB fertilizer, so-called BB fertilizer is the abbreviation of English Bulk Blending Fertilizer, 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, this year No.1 Central File, emphasize again " accelerating the research and development of highly effective and safe fertilizer ", I stands existing 15 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, " Farmers' Daily " reports his forerunner for the research and development of bulk blended fertilizer formula, feel the research and development of quickening highly effective and safe fertilizer deeply to be duty-bound, the formula of staple crops highly effective and safe bulk blended fertilizer is developed in plan.

Summary of the invention

The object of the invention is to the principle according to balance fertilizing " law of cask ", preparation N P and K; Calcium magnesium sulphur; Iron zinc-manganese boron molybdenum chlorine copper is big or middle, micronutrient is complete, and the safe sweet potato mixing fertilizer specially of organic/inorganic high efficient containing organic matter, amino acid, humic acid.

The present invention adopts following technical scheme:

Preparation highly effective and safe sweet potato mixing fertilizer specially, select urea, monoammonium phosphate, potassium sulfate, fertilizer and fused(calcium magnesium)phosphate to be the source of manure, each source of manure characteristic is as follows: urea nitrogenous 46.4%; 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 phosphorous 18%, magnesium oxide 15%, calcium oxide 32%, silicon-dioxide 30%, also containing ferric oxide, the trace elements such as magnesium oxide and a small amount of boron, copper, zinc, molybdenum, nickel, very strong Lian Yingxing is had between each source of manure, one ammonium fusion urea can form high polymer, Releasing nutrient gradually, 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, also play getting fat effect effect, 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, make its Bulk Blending Fertilizer not deliquescence, do not lump.

Embodiment

Often produce 1000 kilograms, with 300 kilograms, urea, monoammonium phosphate 200 kilograms, potassium sulfate 250 kilograms, fertilizer 150 kilograms, 100 kilograms, fused(calcium magnesium)phosphate, stir blending, be made into N P and K three elements 40% (18: 10: 12); Medium trace element 8%; The highly effective and safe sweet potato mixing fertilizer specially of organic matter, amino acid, humic acid 6%;

Concrete blending parameter sees following table:

Claims (1)

1. the invention discloses a kind of highly effective and safe sweet potato special blending fertilizer formula, often produce 1000 kilograms, with 300 kilograms, urea, monoammonium phosphate 200 kilograms, potassium sulfate 250 kilograms, fertilizer 150 kilograms, 100 kilograms, fused(calcium magnesium)phosphate, stir blending, be made into N P and K three elements 40% (18: 10: 12); Medium trace element 8%; The highly effective and safe sweet potato mixing fertilizer specially of organic matter, amino acid, humic acid 6%; Because this formula comprises big or middle, micro-all nutrients, organic, amino acid, humic acid has entirely, has highly effective and safe, the advantages such as price is low, with strong points.
