Description

Technical Field

[0001] The utility model relates to the technical field of soil screening, in particular to a wet screening device for pre-treatment of soil water-stable macroagglomerates. Background Art

[0002] Soil water-stable macroaggregates refer to aggregates in the soil with different sizes and shapes, different porosities, mechanical stability, and water stability. Soil aggregates can improve soil fertility, nutrient availability, and plant resistance to environmental disturbances (such as water, nutrients, and human activities) to promote plant growth, and are an important part of soil science research.

[0003] At present, there are several methods for screening soil aggregates, including dry screening, wet screening and optimal moisture screening, among which wet screening is the most widely used.
