[0029] According to one aspect of the present invention, the present invention also relates to the preparation method of the slow-release fertilizer as described above, comprising:

[0030] The attapulgite, zeolite, dried poultry manure, potassium dihydrogen phosphate, double superphosphate, urea and rhamnolipid are mixed and granulated to obtain the product.

[0031] According to one aspect of the present invention, the present invention also relates to the application of the above-mentioned slow-release fertilizer as a special fertilizer for rice.

[0032] Rice is a fertilizer-loving crop, and soil supply alone cannot meet the growth and development needs of rice. It is necessary to apply corresponding elemental fertilizers according to the characteristics of rice's fertilizer requirements, especially the nitrogen, phosphorus, and potassium elements that require large amounts. The uptake of nitrogen by rice reaches its peak at the tillering stage and heading and flowering st...

Embodiment 1

[0035] The present embodiment provides a slow-release fertilizer, comprising:

[0036] Attapulgite 15-20g, zeolite 26-36g, dry livestock manure 10-20g (pig manure accounts for 50wt%-60wt%, chicken manure accounts for 40wt%-50wt%), potassium dihydrogen phosphate 5-10g, overweight Calcium phosphate 10-20g, urea 5-10g and rhamnolipid 0.1-0.5g;

[0037] The attapulgite, zeolite, dried poultry manure, potassium dihydrogen phosphate, double superphosphate, urea and rhamnolipid are mixed and granulated to obtain the product.

Embodiment 2

[0039] The present embodiment provides a slow-release fertilizer, comprising:

[0040] Attapulgite 15-20g, zeolite 26-36g, dry livestock manure 10-20g (pig manure accounts for 50wt%-60wt%, chicken manure accounts for 40wt%-50wt%), potassium dihydrogen phosphate 5-10g, overweight Calcium phosphate 10-20g, urea 5-10g and rhamnolipid 0.1-0.5g;

[0041] The attapulgite, zeolite, dried poultry manure, potassium dihydrogen phosphate, double superphosphate, urea and rhamnolipid are mixed and granulated to obtain the product.

Abstract

The invention relates to the field of nitrification inhibitors, in particular to the application of a rhamnolipid as a nitrification inhibitor and a slow-release fertilizer containing the rhamnolipid. The slow-release fertilizer includes: 15-20 parts of attapulgite, 26-36 parts of zeolite, 10-20 parts of dried poultry manure, 5-10 parts of potassium dihydrogen phosphate, 10-20 parts of heavy superphosphate, urea 5-10 parts and 0.1-0.5 parts of rhamnolipid. This fertilizer is very suitable for rice cultivation.

Description

technical field [0001] The invention relates to the field of nitrification inhibitors, in particular to the application of a rhamnolipid as a nitrification inhibitor, a slow-release fertilizer containing rhamnolipid and its preparation method and application. Background technique [0002] Nitrogen is an essential element for plant growth, plant health and reproduction. About 25% of the plant-available nitrogen (ammonium and nitrate) in soil originates from the decomposition process (mineralization) of organic nitrogen compounds such as humus, plant and animal residues and organic fertilizers. About 5% is derived from rainfall. However, on a global basis, the largest portion (70%) is supplied to plants by inorganic nitrogen fertilizers. Mainly used nitrogen fertilizers include ammonium compounds or their derivatives. [0003] In addition, because it is a cation, NH 4+ Electrostatically held by the negatively charged clay surface and the functional groups of the soil organ...
