Long-acting nitrogen-phosphor composite fertilizer

Abstract

The invention discloses a long-acting nitrogen-phosphor composite fertilizer, which is composed of the following components in parts by weight: 20 to 30 parts of urea, 20 to 25 parts of monoammonium phosphate, 15 to 22 parts of ammonium sulfate, 8 to 14 parts of diatomite, 6 to 10 parts of ammonium bicarbonate, and 3 to 5 parts of boric acid. The provided long-acting nitrogen-phosphor composite fertilizer can last the fertilizing effect for a long time, and is capable of prolonging the fertilizing time by 2 to 3 times compared with the conventional fertilizers.

Description

technical field [0001] The invention relates to a long-acting nitrogen-phosphorus compound fertilizer. Background technique [0002] Nitrogen-phosphorus compound fertilizer is a compound fertilizer made of chemical substances containing both nitrogen (N) and phosphorus (P), also known as binary compound fertilizer. Elemental nitrogen plays a very important role in crop growth. It is a component of amino acids in plants, a component of protein, and a component of chlorophyll that plays a decisive role in photosynthesis in plants. Nitrogen can also help crops reproduce. Nitrogen fertilizers can not only increase the yield of agricultural products, but also improve the quality of agricultural products. Phosphorus is a component of cell protoplasm in plants and plays an important role in cell growth and proliferation; phosphorus is also involved in photosynthesis in plant life, utilization of sugar and starch, and energy transfer. Phosphorus fertilizer can also promote the gro...
