Description

Technical Field

[0001] The utility model relates to the technical field of water-retaining agent detection, in particular to a device for detecting a water-retaining agent for potato planting. Background Art

[0002] Potato, also known as potato, yam egg, and sweet potato. Potatoes can be used as both food and vegetable, are rich in nutrients, have wide adaptability, a wide range of uses, a long industrial chain, diverse cultivation methods, and can be supplied year-round. Water-retaining agent (SAP) is a chemical water-saving material with a polymer network structure. It has strong water absorption and water retention capabilities and a strong association effect with water. It can absorb hundreds or even thousands of times its own weight in water. Tests have shown that 85% to 90% of the absorbed water can be absorbed by plants. It is non-toxic and has no side effects, does not pollute the environment, and can eventually be degraded into water, nitrogen, and CO2. Numerous studies have shown that water-retaining agents can improve soil structure, increase soil water holding capacity, significantly increase crop emergence rate, reduce soil water and fertilizer loss, and thus promote crop growth and increase yield. Another important function of applying water-retaining agents is to loosen the soil, reduce soil bulk density, increase porosity, and improve soil aeration. Therefore, water-retaining agents are widely used in agriculture.

[0003] Currently, when testing water-retaining agents during potato planting, the water-retaining agents are extracted from the soil, then sealed, and taken to a laboratory for testing to determine the water retention rate. However, this operation is cumbersome and time-consuming. Therefore, there is currently no device that can automatically test the water-retaining agents spread on the surface during potato planting. Therefore, it is necessary to provide a potato planting water-retaining agent detection device to solve the above-mentioned problems. Utility Model Content
