Compound traditional Chinese medicine organic fertilizer and preparation method thereof

Abstract

The invention discloses a compound traditional Chinese medicine organic fertilizer and a preparation method thereof. The compound organic fertilizer comprises the following ingredients in parts by weight: 15-20 parts of potassium sulfate, 10-25 parts of ammonium sulfate, 5-10 parts of high-calcium clay, 10-15 parts of diammonium phosphate, 2-5 parts of fulvic acid, 1-4 parts of soluble chitosan and the like. In the compound fertilizer, various fertilizers, pearlstone and vermiculite are subject to reasonable prescription, and the formula is scientific and reasonable. The compound traditional Chinese medicine organic fertilizer has wide adaptation range, strong and permanent fertilizing value and high seasonal utilization ratio, and the pearlstone and vermiculite in the formula can a remarkable improvement effect on soil texture and enable various plants to achieve high quality and stable yield.

Description

technical field [0001] The invention relates to a compound organic fertilizer and a preparation method thereof. Background technique [0002] The existing formula of compound fertilizer products is unreasonable, and the single pursuit of high-nitrogen or high-potassium compound fertilizers is blind, and the utilization rate is low, and some even cause low-quality agricultural products, endangering the health of consumers; the physical properties are not good, and there is much dust , not compressive, caking, inconvenient for storage, transportation and fertilization. Generally, the utilization efficiency of inorganic fertilizers is low. The main reason is that after inorganic fertilizers are applied to soil or water, they are easily fixed by metal ions such as calcium, magnesium, iron, and aluminum, and are easily adsorbed by clay mineral particles, thereby reducing fertilizer efficiency and affecting The environment is polluted. Phosphorus and potassium in commonly used c...

Problems solved by technology

[0002] The existing formula of compound fertilizer products is unreasonable. The single pursuit of high-nitrogen or high-potassium compound fertilizers is blind, and the utilization rate is low. Some even cause low-quality agricultural products and endanger the health of consumers; the physical properties are not good, and there is much dust. , not compressive, caking, inconvenient for storage, transportation and fertilization

Generally, the utilization efficiency of inorganic fertilizers is low. The main reason is that after inorganic fertilizers are applied to soil or water, they are easily fixed by metal ions such as calcium, magnesium, iron, and aluminum, and are easily adsorbed by clay mineral particles, thereby reducing fertilizer efficiency and affecting environmental pollution

Phosphorus and potassium in commonly used compound fertilizers are easily fixed by metal ions such as calcium, magnesium, iron, and aluminum in wastewater, which reduces the utilization rate of fertilizers. Excessive addition not only increases the cost of chemicals, but also easily exceeds the standard of phosphorus content in the effluent
