The soil aggregate analyzer is a special instrument used to analyze the structure of soil aggregates. In order to better understand the significance of using soil aggregate analyzers to study the structure of soil aggregates, it is necessary to popularize what is a pellet structure. The granule structure is a soil structure in which a number of soil particles are bound together to form agglomerates. This structure is characterized by large pores between granules, small pores within the granules, the presence and size of pores at the same time, a suitable proportion, a high total porosity, and a small void.
Soil granule structure is a kind of special structure, which has an important influence on the growth of plants. For example, the soil granule structure plays a role as an air corridor; it is a small reservoir of crop roots; it is a small fertilizer reservoir for crop growth; The soil structure of the granule structure is loose, easy to cultivate, long suitable tillage period, good tillage quality, easily germinated and unearthed seed, easy to spread roots, and neat emergence; able to maintain high soil biodiversity, etc., thus showing that the soil has a granular structure The soil has the characteristics of water vapor, nutrient supply and accumulation coordination, good ploughability, and good root growth, and is an important guarantee for high yields and stable production in agriculture. Therefore, it is the most ideal structure of soil, and how much it is an important symbol of soil fertility.
The use of a soil aggregate analyzer to study the structure of soil aggregates can help understand the soil conditions, and adopt appropriate measures to form soil aggregate structures for different soil structures, such as adding organic fertilizers to increase soil organic matter content; correct soil cultivation. Rational rotation system; Regulation of soil cation composition, application of soil structure improver; Reasonable irrigation, drying, and freeze hoeing. It can be seen that the use of soil aggregate analyzers to study soil aggregate structure is of very practical significance and value. Its application can provide basis for soil improvement, and it can make practical and effective improvement measures to ensure soil physical and chemical properties. Bio-fertility, the goal of increasing production and efficiency.
