Problems solved by technology

Therefore, it is difficult to screen suitable binders, the production cost is too high, and the production process is unreasonable, etc., which are the main problems currently restricting the popularization and application of lime nitrogen.
[0008] 2. Single performance: The soil conditioner based on lime nitrogen only plays a role in sterilizing and disinfecting the soil. The dosage is large, the cost is high, and the performance is single, and other functions of lime nitrogen cannot be fully utilized.
[0009] 3. Due to the alkaline effect of lime nitrogen, in the process of producing fertilizer products, it is easy to cause the degradation of phosphorus, the volatilization of ammonia nitrogen and the passivation of trace elements, resulting in the loss of nutrient elements and reducing the fertilizer efficiency

Abstract

The invention relates to a lime nitrogen multifunctional particle type soil amendment and a preparation method thereof. The soil amendment raw material comprises the following components: lime nitrogen, auxiliary materials and hot melting adhesives, wherein the auxiliary materials contain brown coal, fulvic acid and zeolite powder, wherein the hot melting adhesives contain urea, polyphosphoric acid and solid paraffin. The lime nitrogen and the auxiliary materials are mixed uniformly and are heated to 80-90 DEG D by heating, the hot melting adhesives are added and heated to 115-125 DEG C, after uniformly stirring, a steel band type granulator is used for granulation and condensation, and the lime nitrogen multifunctional particle type soil amendment is obtained. According to the invention, the composite hot melting adhesives are used as water-retaining agent and chelating agent, the auxiliary materials are used as neutralizer, activator and synergist; after continuous granulation, the product has a low water content, thereby solving the volatilization problem of the lime nitrogen; the prepared lime nitrogen multifunctional particle type soil amendment has a high biological energy and good application effect.

Description

technical field [0001] The invention relates to a lime nitrogen multifunctional granular soil improver and a preparation method thereof, belonging to the technical field of new soil improvers in the agricultural field. Background technique [0002] Lime nitrogen, also known as calcium cyanide nitride, is an ancient chemical fertilizer with a history of more than 100 years of use. In the 1960s and 1970s, lime nitrogen was widely used in my country's agricultural field, such as making rice base fertilizer, adjusting soil acidity, and supplementing calcium for plants. With the rise of the chemical fertilizer industry and the increase and popularization of high-efficiency fertilizer varieties, lime nitrogen, an ancient fertilizer variety, has gradually withdrawn from the market and been neglected. Due to the alkaline effect of lime nitrogen, when producing fertilizer products, it is easy to cause the degradation of phosphorus, the volatilization of ammonia nitrogen and the pass...
