Auxiliary agents, also known as additives, are substances that are added to a material to improve or modify its properties. In the field of polymers, auxiliary agents are commonly used to enhance the processing, performance, and durability of polymer materials.

Greenhouse temperature: 18-32°C in seedling stage, 25-38°C in melon period; greenhouse humidity LzUI The relative humidity in the air suitable for the growth and development of cucumber is 70%-90%; soil moisture: soil in early flowering stage, early melon stage, and melon stage The moisture content was kept at 55%-90%, 70%-90%, and 75%-90%, respectively. During the production process, “greenhouse dolls†are used to monitor environmental factors in the greenhouse in real time, and according to the prompts, agricultural activities such as watering, turning on and off the fans, covering and rolling up the insulation are performed in time to ensure the suitable greenhouse temperature, Humidity and soil moisture etc.
The results showed that the cucumber greenhouse used "greenhouse dolls" to manage, using a small water pouring method, both to meet the growth needs of cucumber, but also to achieve the purpose of water conservation. Secondly, due to the control measures of the technology, it provides a good growth environment for cucumber growth, reduces the incidence of disease, reduces the prevention of diseases, and the effect of increasing production and income is also very obvious.
The application of “greenhouse dolls†further demonstrated the development potential of science and technology agriculture, greatly improved the scientific management of agricultural production facilities, improved the utilization of agricultural resources, land productivity and labor productivity, reduced labor intensity and costs, increased production and Benefits have promoted the sustainable development of facility agriculture.
There are several types of auxiliary agents, each with its own unique properties and applications. The most common type is processing aids, which are added to polymer materials to improve their flow and moldability during processing. Processing aids can improve the surface finish of the final product and reduce the amount of energy required during processing.
Another type of auxiliary agent is plasticizers, which are added to polymer materials to increase their flexibility and reduce their brittleness. Plasticizers can improve the toughness and impact resistance of the final product and are commonly used in the production of flexible PVC products, such as hoses and films.
Other types of auxiliary agents include stabilizers, which are added to polymer materials to protect them from degradation caused by heat, light, or chemical exposure. Stabilizers can improve the durability and longevity of the final product and are commonly used in outdoor applications, such as building materials and automotive parts.
Colorants, fillers, and flame retardants are also common types of auxiliary agents. Colorants are added to polymer materials to give them a specific color, while fillers are added to improve the mechanical properties of the final product, such as its strength and stiffness. Flame retardants are added to polymer materials to reduce the risk of fire and are commonly used in applications where fire safety is critical, such as building materials and electronics.
The choice of auxiliary agent depends on the specific application requirements and must be carefully considered to ensure that the final product meets the desired specifications. It is important to select the appropriate auxiliary agent to achieve the desired performance, processing, and durability characteristics of the polymer material.
In summary, auxiliary agents play an important role in the processing, performance, and durability of polymer materials. There are several types of auxiliary agents, each with its own unique properties and applications, and the choice of auxiliary agent depends on the specific application requirements.
“Greenhouse Doll†is an environmental detection instrument that uses sensor technology to detect real-time temperature, air humidity, soil moisture, and light in greenhouses, and displays it on the Chinese LCD screen. The application of “greenhouse dolls†to cucumber cultivation in greenhouses can guide farmers to manage the greenhouse environment reasonably and effectively, achieve the purpose of fine management of greenhouses, promote the scientific and rational agricultural activities of farmers, and increase the income of farmers. According to the greenhouse cucumber planting requirements, the "greenhouse doll" parameters are set as follows.
