Abstract

The invention provides a special fertilizer for paddy rice and a preparation method of the fertilizer. The special fertilizer for the paddy rice is developed for the paddy rice, contains rich elementssuch as nitrogen, phosphorus and potassium, and effectively guarantees nutrients required in a paddy rice growth process. Potassium polyaspartate is added in a formula, is a metal salt, can chelate with various metal ions, effectively reduces absorption of crops for chromium ions and reduces sedimentation of chromium in tissues and organs in a human body; moreover, carboxymethylcellulose is alsoadded in the formula, adds a chelation structure and promotes the chromium ion absorption.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a fertilizer specially used for rice and a preparation method thereof. Background technique [0002] Rice is an important food crop in my country. Its sown area and total output rank second only to wheat, and it occupies an important position in agricultural production. Rice fertilization is mostly based on conventional elemental fertilizers such as urea, ammonium bicarbonate, and diammonium phosphate. Long-term application of simple fertilizers will have adverse effects on soil and crops. Some fertilizers may also contain harmful metals such as chromium, which will seriously affect the quality of rice after being absorbed by rice, and then threaten human health. [0003] Chromium pollution, as one of the main pollutants of harmful heavy metal pollution, seriously threatens human health. If swallowed by mistake, it can cause abdominal discomfort, diarrhea and o...
