Abstract

The invention discloses a sustained release nitrogen and phosphorus compound fertilizer. The sustained release nitrogen and phosphorus compound fertilizer comprises the following components in parts by weight: 30-45 parts of urea, 25-40 parts of acrylamide, 22-28 parts of ammonium persulfate, 20-25 parts of ylidene bisacrylamide, 18-24 parts of ethyleneamine tetraacetic acid, 16-18 parts of sodium metabisulfite, 12-15 parts of monoammonium phosphate, 8-14 parts of ammonium sulfate, 5-8 parts of diatomite, 5-8 parts of ammonium bicarbonate and 1-2 parts of boric acid. The sustained release nitrogen and phosphorus compound fertilizer has the beneficial effects that the sustained release nitrogen and phosphorus compound fertilizer has high fertility persistence, and the fertilizer efficiency time can be prolonged by 3-4 times compared with that of an existing fertilizer.

Description

Technical field [0001] The present invention involves a long -acting slow -release nitrogen phosphorus compound fertilizer. Background technique [0002] Nitrogen and phosphorus compound fertilizer is complicated fertilizer made of chemicals made of nitrogen (n) and phosphorus (P), which is also called dual compound fertilizer.Elemental nitrogen plays a very important role in crop growth. It is part of the amino acids in the plant, the ingredients that constitute the protein, and the chlorophyll component of the plants to determine the decisive effect.Nitrogen fertilizer can not only improve the yield of agricultural products, but also improve the quality of agricultural products.Phosphorus is a component of the original cells in the plant, which plays an important role in the growth and proliferation of cells; phosphorus also involves the photosynthetic effect of the plant life process, the use of sugar and starch, and the transmission process of energy.Phosphorus fertilizer can...
