Abstract
The present invention is a kind of Ecological slow-release fertilizer of polymerization amino acid: it is characterized in that the NpK complex fertilizer comprising 99-99.3%, 0.7-1% additive, described additive comprises the poly aspartic acid of 20-30%, the polyglutamic acid of 20-30%, the nitrification inhibitor of 40-60%, the fertilizer releasing period of described Ecological slow-release fertilizer of polymerization amino acid reaches more than 100 days.
Description
Technical field
The present invention relates to a kind of fertilizer, particularly a kind of Ecological slow-release fertilizer of polymerization amino acid.
Background technology
All the time, it is large that the chemical fertilizer application aspect of China also exists rate of fertilizer application, nutrient loss is too fast, the feature that Crop is not high, can cause the waste of resource like this, environmental pollution, therefore strengthen the absorption of fertilizer in research, improve the utilization ratio of fertilizer, reduce the input of fertilizer, reduce costs, for China agricultural development have very important significance.
Summary of the invention
The present invention is exactly for the problems referred to above, provides a kind of Ecological slow-release fertilizer of polymerization amino acid, not only can prevent the loss of nutrient, can also improve the utilization ratio of nutrient.
A kind of Ecological slow-release fertilizer of polymerization amino acid: it is characterized in that the NpK complex fertilizer comprising 99-99.3%, 0.7-1% additive, described additive comprises the poly aspartic acid of 20-30%, the polyglutamic acid of 20-30%, the nitrification inhibitor of 40-60%, the fertilizer releasing period of described Ecological slow-release fertilizer of polymerization amino acid reaches more than 100 days.
Described nitrification inhibitor is Dyhard RU 100, methylpyrazole and Truban, and mass ratio is 3:1:2.
Poly aspartic acid (molecular formula: C
4h
6nO
3(C

Polyglutamic acid (molecular formula: L-Glu-(L-Glu) n-L-Glu), polyglutamic acid is through the amino acid classes of traditional beans fermentation of materials, molecular weight 20,000 unit.
This two seed amino acid can both be applied in fertilizer, and preparation method is simple, is easy to get, and the amino acid material produced is stablized, and is beneficial to preservation.Utilize this two seed amino acid to add in fertilizer, effectively can improve the utilization ratio of fertilizer, the nutrient ion such as ammonium, potassium, zinc, iron, magnesium, molybdenum in soil can be adsorbed in a large number, improve absorption nutrient and the water retention capacity of crop, improve the utilization ratio of fertilizer.But, only add this two seed amino acids class material, the supply of crop nutrient whole breeding time can not be reached.
Find nitrification inhibitor to mix according to certain ratio through research, be just prepared into the fertilizer additive that can reach crop nutrient supply in the time of infertility.Add in the production of NPK fertilizers according to certain ratio, just made the polymeric amino acid slow release fertilizer possessing a bottom application and no longer to topdress the time of infertility.
Embodiment
Below in conjunction with specific embodiment to invention has been further description.
A kind of Ecological slow-release fertilizer of polymerization amino acid: it is characterized in that the NpK complex fertilizer comprising 99-99.3%, 0.7-1% additive, described additive comprises the poly aspartic acid of 20%, the polyglutamic acid of 20%, the nitrification inhibitor of 60%, the fertilizer releasing period of described Ecological slow-release fertilizer of polymerization amino acid reaches more than 100 days.
Described nitrification inhibitor is Dyhard RU 100, methylpyrazole and Truban, and mass ratio is 3:1:2.
If NpK complex fertilizer is containing the N P and K total nutrient of 45%, the nutrient of nitrogen is in the compound manure of 25%, the addition 0.8% of additive; N P and K total nutrient is greater than 48%, and nitrogen nutrient is the addition of additive in the compound manure of more than 26% is 1%; N P and K total nutrient is less than 45%, and the addition of the additive in the compound manure of nitrogenous fertilizer nutrient below 25% is 0.7%.
Find after deliberation, this additive can improve the utilization ratio of nutrient greatly, improves utilization rate of nitrogen fertilizer and reaches 20-25%, the utilization ratio improving phosphorus reaches more than 15%, and improve potassium utilization rate more than 18%, fertilizer releasing period reaches more than 100 days, make a crop bottom application, a season exempts to chase after.
Certainly; the above is only one embodiment of the present invention; should be understood that those skilled in the art; under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications all belong within the protection domain of the claims in the present invention.
