Active compound missible oil preparation and water-soluble preparation for improving pH value of soil and application

Abstract

The invention discloses an active compound missible oil preparation and a water-soluble preparation for improving the pH value of soil and application, and belongs to the technical field of bio-pesticide and preparation processing. The active compound is one or more of 2,6-dimethoxyphenol, 2-ethylphenol, 4-ethylphenol, 3-methoxycatechol, 2,5-di-tert-butyl phenol, 4-allyl-2,6-dimethoxyphenol, 2,3-dimethyl-2-cyclopentenone, acetosyringone, vanillin and syringaldehyde. The active compound missible oil preparation and the water-soluble preparation have the advantages that the production cost is low, the pH value of soil can be rapidly and durably increased, the used active ingredients, solvents and emulsifier are natural products and meet the requirements of organic agriculture and green agriculture, the missible oil preparation can be used for soil improvement of organic agriculture and green agriculture, and the water-soluble preparation can be used for soil improvement of pollution-freeagriculture.

Description

technical field [0001] The invention belongs to the technical field of biopesticide and preparation processing, and specifically relates to an active compound emulsifiable concentrate preparation and a water-soluble preparation for increasing soil pH and its application. Background technique [0002] Soil acidification refers to the absorption of a certain amount of hydrogen and aluminum ions by the soil, resulting in a decrease in pH value, affecting the activity of organisms in the soil, changing the form and availability of nutrients, and promoting the dissolution of manganese and aluminum ions into the soil solution, causing plant poisoning. Soil acidification inhibits root development and aggravates soil compaction, resulting in reduced yield. Soil acidification aggravates the waste of pesticides and can also lead to fertilizer loss. For example, the fertilizer utilization rate is less than 30%, 70% of nitrogen is lost, and 60-80% of phosphorus and potassium cannot be a...

Soil acidification inhibits root development, aggravates soil compaction, and reduces yield

Soil acidification aggravates the waste of pesticides, and can also lead to fertilizer loss, such as fertilizer utilization rate of less than 30%, 70% of nitrogen loss, 60-80% of phosphorus and potassium cannot be absorbed, resulting in increased input

At present, the appropriate addition of limestone or dolomite is considered to be an effective method to prevent soil acidification and increase soil nutrients. This method has been applied to a certain extent in countries such as Europe and the United States. Its advantage is that it can alleviate or eliminate soil acidification and its impact relatively quickly. However, its side effects cannot be ignored, especially the decrease of soil organic matter content.
