The past decade has been a decade of compound fertilizer development, and a large amount of compound fertilizer has been applied to the soil. In the past ten years, it has also been a key decade for soil quality decline. In many areas, soils have been destroyed due to chemical fertilizer abuse, and soil quality has continued to decline. To ensure the sustainable development of agriculture and to take an efficient development route, it is necessary to solve the fundamental problem of agricultural development - the quality and safety of soil. The soil measuring instrument is used to guide the agriculture to carry out soil testing and formula fertilization, and to increase the fertilizer and increase the efficiency in a scientific way, so that the soil can be renewed and revived.
There is a strong relationship between the decline in soil quality and the irrational application of fertilizers. We know that there is a popular saying in agricultural production that “a crop is a flower, and it depends on the fat to be the masterâ€. Therefore, in order to obtain high yield, farmers’ friends often exchange for the input of chemical fertilizers, and a large number of fertilizers that are not absorbed and utilized by crops remain. In the soil, it becomes a serious burden on the soil and leads to problems such as soil compaction, acidification and salinization. The soil testing instrument is used to test the soil. On the one hand, it is necessary to understand the true quality of the soil, and provide a basis for subsequent development and improvement. On the other hand, it is necessary to carry out scientific fertilization, balanced fertilization, etc. on the basis of production. Give full play to the fertilizer efficiency of resources such as fertilizers in exchange for the double growth of ecological and economic benefits.
At present, the agricultural sector attaches great importance to soil conservation and efficient use of soil. Although China is a big agricultural country, many farmers have been dealing with the land for half a lifetime, but the understanding of the soil is still poorly understood. To promote the green, ecological and efficient development of agriculture, it is necessary to fully understand the soil quality before it can better carry out soil protection and quality improvement. The soil measuring instrument is an important tool for us to understand the quality of the soil. With its support, scientific fertilization can be followed, not only to save costs, to protect the environment, but also to improve soil quality and improve the yield and quality of crop cultivation.
An eyedrop tube packaging is a small, plastic container with a nozzle that is used to administer liquid medication directly into the eye. The tube is typically made of a clear, flexible plastic material that can be squeezed to release drops of medication. The nozzle is designed to fit over the eye and deliver a precise amount of medication with each drop. Eyedrop tubes are commonly used to treat a variety of eye conditions, such as dry eyes, allergies, and infections. They can be purchased over-the-counter or prescribed by a doctor.
