Problems solved by technology

While this kind of compound fertilizer brings high yield to agricultural production, it also imperceptibly changes the physical and chemical properties of the soil. The application of a large amount of acid radical ions intensifies the loss of cations in the soil, reduces the ion exchange capacity of the soil, and further causes soil pollution. Acidification, compaction, and decline in fertilizer supply capacity, which in turn affect agricultural production
[0004] In order to ensure the output of agricultural production, the use of fertilizers has to be increased. The cost of applying pesticides and fertilizer

Abstract

The invention discloses a neutral compound fertilizer which is composed of 10-80 parts of nitrogenous fertilizers, phosphate fertilizers and potash fertilizers, 0-10 parts of microelement fertilizers, 1-7.5 parts of citric acid solvent magnesium oxide, 0-20 parts of humic acid and 0-0.08 part of plant growth regulator according to weight. The neutral compound fertilizer nutritionally balanced by comprising major elements needed in crop growth as well as microelements and secondary elements indispensable in crop growth, and can reduce fertilization times and save labor. The citric acid solvent magnesium oxide is creatively added so as to neutralize the acid radical in the fertilizer and make the produce to be physiologically neutral. Therefore, the neutral compound fertilizer can provide necessary magnesium nutrients for crops, improve the acid-base property, promote photosynthesis and enzyme activation, hasten crop growth, improve crop resistance, avoid soil acidification and soil salt and alkali accumulation, increase output, improve the quality and achieve yield increase and income increase. The neutral compound fertilizer does not need additional equipment in production and is simple in process, low in cost, high in added value and wide in the application prospect.

Description

technical field [0001] The invention relates to a compound fertilizer, in particular to a neutral compound fertilizer and a preparation method thereof. Background technique [0002] Compound fertilizers are made of ready-made elemental fertilizers, compound fertilizers or chemical raw materials (such as urea, ammonium phosphate, potassium chloride, potassium sulfate, ammonium sulfate, ammonium chloride, etc.), supplemented by additives (bentonite, clay, etc.) ), fertilizer made by mixing, processing and granulating. Most of the compound fertilizers currently on the market are of this type. [0003] GB / T 15063-2009 National Standard for Compound Fertilizers does not require the pH of compound fertilizer granules. Most of the raw materials for compound fertilizers are produced from monoammonium phosphate, ammonium sulfate, potassium sulfate, urea, and potassium chloride. Potassium sulfate Due to the residual part of potassium bisulfate, the pH of potassium sulfate is acidic,...
