Preparation process of silica powder-based fertilizer beneficial to soil improvement

Abstract

The invention discloses a preparation process of silica powder-based fertilizer beneficial to soil improvement, and is characterized in that the process comprises the following steps: (1) adding and uniformly mixing soybean hulls, water hyacinths, bentonite and a physalis alkekengi aqueous solution, and pulverizing the mixture into powder for standby use; adding ethanol of which the weight is 10 times weight of the mixed powder with a volume fraction of 80% into the mixed powder; performing immersing extraction for 30 days at 20-35 DEG C; obtaining a filtrate by filtration through 200-mesh screen, and recovering ethanol in the filtrate. The silica powder-based fertilizer is rich in nutrients. Silica powder also has a plurality of micropores, which cooperates with the porous carrier to promote the absorption of fertilizer components by crop roots and improve the utilization ratio of nutrients.

Description

Technical field [0001] The invention relates to the technical field of fertilizers, in particular to a preparation process of a silicon micropowder-based fertilizer that is beneficial to soil improvement. Background technique [0002] As the largest developing country in the world, China has a large population and increasingly serious resource and environmental problems. In order to meet the increasing population demand for crop yields, people apply a large amount of chemical fertilizers, especially the application of large amounts of inorganic fertilizers, which has caused serious damage to the soil structure. As the physical and chemical properties of the soil deteriorate, the nutrient balance becomes imbalanced, and the soil fertility decreases, which in turn leads to the deterioration of the ability to withstand natural disasters, and ultimately seriously affects the normal growth of crops and the increase in yield. At the same time, the loss of fertilizer nutrients in the s...

Problems solved by technology

In order to meet the demand for crop yields due to the increase in population, people use a large amount of chemical fertilizers, especially the application of large amounts of inorganic fertilizers, resulting in serious damage to the soil structure.

With the deterioration of soil physical and chemical properties, the imbalance of nutrients and the decline of soil fertility will lead to the deterioration of the ability to resist natural disasters, which will seriously affect the normal growth and yield of crops.

At the same time, the leaching loss of fertilizer nutrients in the soil is large. The loss of fertilizer nutrients not only increases the cost of agricultural input, but also enters the water resource cycle system, causing further water pollution and affecting the safety of human drinking water.

Moreover, the crops produced in such a soil environment seriously threaten the health of consumers
