Long-acting nitrogen-rich rice special organic fertilizer and preparation method thereof

Abstract

The invention discloses a long-acting nitrogen-rich rice special organic fertilizer prepared from the following raw materials by weight: 10-16 parts of urea, 1-2 parts of bentonite, 15-20 parts of pig blood powder, 25-35 parts of sweet potato vine, 5-7 parts of fig leaf powder, 12-16 parts of sugar residue, 6-8 parts of distiller's grains, 5-7 parts of calcium superphosphate, 0.1-0.2 part of urease inhibitor, 8-10 parts of coffee slag, 15-20 parts of buffalo milk powder, 5-6 parts of potassium sulfate, 4-5 parts of silicon sulfate, 4-5 parts of potassium dihydrogen phosphate, 20-30 parts of a soil conditioner, and proper amount of water; compared with traditional fertilizers, the use mount of the organic fertilizer is greatly reduced, by addition of the sweet potato vine, the pig blood powder, the buffalo milk powder and other organic matters with rich nutrient elements, soil can be improved effectively improved and fattened, soil organic matter content is increased, the added urease inhibitor slows hydrolysis of tillering stage urea, ammonium nitrogen content in booting stage soil is improved, and the organic fertilizer provides adequate nitrogen fertilizer for later stage growth of rice.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a long-acting nitrogen-enriched special organic fertilizer for rice and a preparation method thereof. Background technique [0002] my country is a large agricultural country, and agriculture is the foundation of the national economy, of which planting accounts for more than half, and the quality of fertilizers directly affects the output of planting, and is an important factor for increasing crop production. However, in order to pursue crop yields, farmers blindly apply chemical fertilizers, resulting in a downward trend in soil organic matter content, weakened soil buffer capacity, decline in disaster resistance, low fertilizer use efficiency, and reduced soil fertility. With the emergence of environmental problems caused by excessive use of chemical fertilizers, the promotion of pollution-free agriculture, and the continuous expansion of the research field of new fertilize...
